Thermoelectric generators convert heat directly into electricity using a fuel source for heat, a hermetically sealed thermopile, and cooling fins. These generators are a positive and cost effective solution for remote power requirements, having operational and cost benefits over batteries and solar sources for many applications.
To identify key areas in the steam generation cycle, condensate recovery system and waste heat recovery process where cost-effective instrumentation solutions offer a tangible return on investment over the short term. The goal is to reduce heat rate, environmental impact, fuel and water consumption, water treatment and maintenance costs in commercial and heavy industries where steam generation is essential to the production processes.
Electronic displacer level transmitter technology operates by detecting changes in buoyancy force caused by liquid level change. These forces act upon the spring supported displacer causing vertical motion of the core within a linear variable differential transformer.
As the core position changes with liquid level, voltages are induced across the secondary windings of the LVDT. These signals are processed in the electronic circuitry and used to control the current in the 4-20 mA current loop. The enclosing tube acts as a static isolation barrier between the LVDT and the process media.
The use of LNG is a proven, reliable, and safe process, and natural gas is quickly becoming the world’s cleanest burning fossil fuel as it emerges as the environmentally preferred fuel of choice. It is for this reason that LNG facilities are put under more pressure than ever to meet the world’s natural gas demand. Keeping your plants running at an efficient pace is vital to production and condition monitoring plays a critical part in this process. Condition monitoring provides a proactive approach so that maintenance can be planned, eliminating unscheduled outages and optimizing machine performance. In addition, condition monitoring helps to avoid breakdowns with subsequent secondary damage and loss of production revenue meaning that today’s LNG facilities simply can’t afford to not have a reliable condition monitoring solution.
The technology and thermal efficiencies of the coal-fired
cycle have improved dramatically, and the basic idea
of converting the stored energy of coal into electricity
accounts for more than 40% of the world’s power.
Hydraulic power units (HPU’s) complement Rotork's extensive offering of rotary and linear actuators.

BIST (Built-in-Self-Test) Features for Electronic Valve ActuatorsMead O'Brien, Inc.
The development and implementation of safety related devices in plant systems is crucial for dependable operation, not to mention peace of mind. Safety and safe operation were once only high priorities for installations that involve hazardous environments. Expensive certification testing was, and still is, paramount to meeting the hazards of such environments, but a new level of plant-wide integrity is emerging — that of Safety Integrity Level (SIL) and SIS. SIL is a safety rating that can be derived by analyzing a system to determine the risk of a failure occurring and the severity of its consequences. Safety Instrumented Systems (SIS) are systems containing instrumentation or controls installed for the purpose of preventing or mitigating a failure either by emergency shut down (ESD) or diverting the hazard. New or replacement equipment must have the ability to be introduced into plant systems without jeopardizing either the SIL of the operation or negatively impacting the SIS.

Electrical rooms provide safe and secure spaces for the operation and maintenance of electrical equipment. While electrical equipment types and ratings can have significant impacts on electrical room requirements, distributing the electrical power to the rest of the building via wiring, busways, and raceways can also affect electrical room design.
Switchboards, switchgear, transformers, generators, and UPSs require space for installation, maintenance, heat dissipation, and possible future expansion. And the wiring, busways, and raceways that distribute the electrical power must be accounted for—now, and in the future. Documentation and monitoring of electrical system’s equipment and how it connects to the rest of the facility must be accurately maintained.
The design of electrical rooms requires an integrated approach among disciplines. Architects and structural, mechanical, and fire protection engineers should work as a team in designing these rooms. NFPA 70: National Electrical Code (NEC) is the main source for electrical room requirements, but other codes, good practices, and recommendations should be considered. The result will be a room that is safe and secure, and provides for the functional operation and maintenance of the specific electrical equipment located within.

White paper - Ingeteam's new-generation power converters for 6-8 MW wind tur...Ingeteam Wind Energy
The wind sector is globally focusing its efforts on reducing the Levelized Cost of Energy (LCoE) of the technology in order to prove itself as a profitable option in the energy mix regarding electrical generation. In response to this market outlook, OEMs are working hard to develop wind turbines with a power range exceeding 6 MW, which potentially enables the reduction of the LCoE of the wind farm.
The upgrade of the power converter to power rates above 6 MW requires a detailed knowledge of DFIG features, especially the main design constraints of this topology, like the peak currents during FRT events, or the mechanical behavior of the whole converter inside the wind turbine. The design process followed by Ingeteam covers all these aspects and the new generation products ensure the reliable operation of the system.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Our Mission:
To be the dominant supplier of reliable remote
power systems for industrial customers in the world’s
toughest environments.
TEGs: SIMPLE, INNOVATIVE TECHNOLOGY
Our legacy product line of thermoelectric generators, convert heat directly into
electricity. As heat moves from a gas burner through a thermoelectric module, it
causes an electrical current to flow.
The heart of a GPT thermoelectric generator is a hermetically sealed
thermoelectric module (thermopile) which contains an array of lead-tin-telluride
semiconductor elements. This durable module provides a chemically stable
environment for the thermoelectric materials which ensures a long service life.
On one side of the thermopile, a gas burner is installed, while the opposite side
is kept cool by aluminum cooling fins or a heat pipe assembly. An operating
generator maintains a temperature of approximately 540ºC on the hot side and
140ºC on the cold side. The heat flow through the thermopile creates steady DC
electricity with no moving parts.

4. How Thermoelectric Generators Stack Up
100 watt system
cathodic protection, Louisiana, USA
COMPARED TO THE POWER GRID...
RELIABILITY: Power grid reliability can be a concern in many countries,
particularly in developing countries where the reliably is often below the
requirements of many applications. The installation of a GPT thermoelectric
generator is a common solution for customers requiring highly reliable
power for automation, cathodic protection and telecom applications.
COST: Even in developed countries with a reliable grid infrastructure,
the capital cost and service charges associated with running grid lines to
a remote location can be prohibitive. In such cases, the installation for
a thermoelectric generator to meet local power requirements is often a
more cost effective solution.
COMPARED TO GENSETS...
MAINTENANCE, RELIABILITY: While the capital cost of diesel or natural
gas gensets is typically lower than that of a thermoelectric generator, the
requirement to have a skilled technician perform regular maintenance
on the gensets results in greatly increased operational costs, increased
downtime and overall reduced reliability. When the complete life cycle
costs, including all operational costs, are compared, the thermoelectric
generator has lower operational costs and is more reliable.
COMPARED TO PHOTOVOLTAICS...
LIFE CYCLE COST AND PERFORMANCE: Although properly sized
photovoltaic systems have shown promise in providing low power
solutions in areas with high solar insolation, solar users are increasingly
turning to thermoelectric generators because of problems with reliability,
short battery life and theft.
GPT’s thermoelectric generators have a 20-year design life and require
minimal maintenance over the life of the system. An equivalent
photovoltaic system would require 20-year life batteries - the cost of
batteries alone can be as much as the thermoelectric generator. Studies
have shown that when the capital cost of a photovoltaic system is based
on medium life batteries (i.e. 10 years), the true life cycle cost of the solar
system is much higher than that of a thermoelectric generator due to the
high cost of battery replacement and higher maintenance costs. Theft and
vandalism have not been a concern with GPT systems, which are small
and unobtrusive, and can be mounted inside security shelters if required.
