This document summarizes the design of a duct system for recirculating air within a house. It includes the dimensions of the ducts, a schematic of the duct layout, information about the selected fan such as its curve, and an equivalent circuit diagram of the system. It then describes the method used to calculate the required fan operating speed to achieve an outlet velocity close to 25 ft/s without exceeding it. The results determined the required airflow is 2040 cfm, fan speed is 1607 RPM, and maximum pressure loss and outlet velocity meet specifications.
Estimating The Available Amount Of Waste Heat
The document estimates the available waste heat from the flue gases of an asphalt dispenser machine used in a dry cell manufacturing plant. The machine uses LPG burners to melt asphalt and seal dry cells. Hot flue gases from combustion are currently exhausted and lost. The study aims to quantify this waste heat for potential recovery. It outlines the machine's operation, describes the flue gas properties, and presents equations to calculate the gas temperature reduction possible before condensation and the resulting recoverable sensible heat.
Separating and throttling calorimeter for steam
This document describes an experiment conducted to determine the quality (dryness fraction) of steam passing through a steam main using a separating and throttling calorimeter setup. The calorimeter was developed on a diesel-fired boiler in a thermal power laboratory. The experiment measured parameters like steam temperature, pressure, and flow rates. Steam was sampled from the main and passed through a separator to remove water, then throttled to a lower pressure and superheated region where its dryness fraction could be calculated using energy equations and steam tables. Factors affecting the accuracy of the experiment like measurement errors and device leaks were also discussed.
Draught and chimney
Natural draught is produced by a chimney and provides ventilation for boiler systems. The height and diameter of a chimney can be calculated based on factors like flue gas temperature, ambient temperature, and air-fuel ratio. For maximum discharge of hot gases, the flue gas temperature should be slightly higher than ambient temperature. Chimneys provide advantages like no external power requirements but have limitations like low efficiency below 1%. Boiler performance is quantified by equivalent evaporation and efficiency, which allow standardization based on feed water temperature and pressure.
Evaluating Pipeline Operational Integrity - Sand Production
Piping systems associated with production, transporting oil & gas, water/gas injection into reservoirs, experience wear & tear with time & operations. There would be metal loss due to erosion, erosion-corrosion and cavitation to name a few. The presence of corrosion defects provides a means for localized fractures to propagate causing pipe ruptures & leakages. This also reduces the pipe/pipeline maximum allowable operating pressure [MAOP].
The following document covers methods by DNV standards to quantitatively estimate the erosion rate for ductile pipes and bends due to the presence of sand. It is to be noted that corrosion can occur in many other scenarios such as pipe dimensioning, flow rate limitations, pipe performance such as pressure drop, vibrations, noise, insulation, hydrate formation and removal, severe slug flow, terrain slugging and also upheaval buckling. However these aspects are not covered in this document.
Based on the erosional rates of pipes and bends, the Maximum Safe Pressure/Revised MAOP is evaluated based on a Level 1 Assessment procedure for the remaining strength of the pipeline. The Level 1 procedures taken up in this tutorial are RSTRENG 085dL method, DNVGL RP F-101 (Part-B) and PETROBRAS’s PB Equation.
ECONOMIC INSULATION FOR INDUSTRIAL PIPING
Thermal Insulation for Industrial Piping is a common method to reduce energy costs in production facilities while meeting process requirements. Insulation represents a capital expenditure & follows the law of diminishing returns. Hence the thermal effectiveness of insulation needs to be justified by an economic limit, beyond which insulation ceases to effectuate energy recovery. To determine the effectiveness of an applied insulation, the insulation cost is compared with the associated energy losses & by choosing the thickness that gives the lowest total cost, termed as ‘Economic Thickness’.
The following tutorial provides guidance to estimate the economic thickness for natural gas piping in winter conditions as an example case study.
design and analysis of heat exchanger
The document summarizes the design and analysis of an air-cooled heat exchanger for a 3-phase induction motor. It outlines specifications for the heat exchanger including air flow rates, temperatures, and heat exchange capacity. It then describes an 8-step process for the design including selecting materials, configuring piping, calculating heat transfer coefficients, and evaluating effectiveness. The scope of the project is defined as developing a prototype while considering losses, fan calculations, cost analysis, and testing iterations through graphical plotting.

This document discusses modifications made to improve the output of a gas turbine-heat recovery steam generator (GT-HRSG) system. The modifications included installing an inlet air chilling system and converting the evaporator section of the HRSG.
The inlet air chilling system cooled the intake air for the gas turbine, allowing it to operate at higher loads while keeping exhaust temperatures low. This provided more flexibility before temperature controls kicked in. Measurements showed the chilled air increased gas turbine mass flow and output.
Supplementary firing in the HRSG was heating the superheater section excessively. To address this, the evaporator section was converted to move the superheater further downstream. This protected the superheater from

Turbomachinery Engineers often conduct studies to determine if a hot gas bypass is required for a given centrifugal compressor system. This would mean building a process model and simulating it for Emergency Shutdown conditions (ESD) & Normal Shutdown conditions (NSD) to check if the compressor operating point crosses the surge limit line (SLL). A quick estimation method that uses dimensionless number called the inertia number can be used to check prior to the study, if a Hot gas bypass (a.k.a. Hot Recycle) is required in addition to an Anti-surge line (ASV or a.k.a Cold Recycle).

It explains that the Dual cycle generalizes the Otto and Diesel cycles by allowing both constant volume and constant pressure heat addition. It also notes that the Diesel cycle has lower efficiency than the Otto cycle at the same compression ratio but is used in combustion engines because it requires higher compression to ignite fuel.
Evaporation Pond Process Design in Oil & Gas Industry
In the upstream oil & gas industry, produced water is a by-product of well production. Hydrocarbon wells initially produce less water but in late field life, the water content increases. Produced water can contain oil carryover and a host of salts with TDS ranging anywhere from 2,000 mg/L to 40,000 mg/L for which evaporation ponds are used to concentrate by evaporating the associated water.
The energy requirement consists of pumping concentrate to the pond and in some cases aeration is provided to enhance the rate of evaporation. The ponds are lined with synthetic liner material to prevent seepage of water into the soil. In case of any corrosive compounds in the water, the number of layers is increased. Landscape and topography play a role in setting up evaporation ponds and it is necessary to have a flat terrain to avoid any overflow of the contents.
Evaporation ponds must also ensure that the amount of water entering is minimized and avoid any flooding. As part of waste disposal, the ponds maybe designed to accumulate sludge over the life time of the operating wells or can be periodically removed. The below figure depicts an evaporation pond.
The following article focuses on estimating the rate of evaporation, water surface temperature and rate of heat transfer to the water in an evaporation pond.

DESIGN OF AIR PRE HEATER AND ECONOMIZER
Heat/light/electrical energy is out today’s necessity and has scarcity also. Energy conservation is key requirement of any industry at all times.
In general, industries use heat energy for conservation of raw material to finished product. The source of heat energy is generally saturated or super heated steam. The steam generation is common use one boiler with carity of fuels. Whatever may be the fuel the generation should be as economy as possible which adds to the product cost. Further the usage of steam and recycling steam condensate back to boiler is an art depending on plant layouts.
In this project the steam generator is water tube boiler fired with rice husk. The steam is transferred to the tyre/tube moulds where tyres/tubes are cured while the heat is rejected to the tyres the condensate forms and this condensate is put back to the boiler. While doing so the steam is also stopped back to boiler without rejecting complete heat to the product. This gets flashed into atmosphere at feed water tank. The science of separation of condensate from steam saves energy. Better the separation more the fuel conservation.
In the steam generator the fuel is burnt to heat the water and form steam. This fuel burnt flue gas carries lot of energy, out through chimney. Prior to exhausting through the heat left in flue need to be recovered, through heat recovery mechanisms’. In this project an air-preheater condensate heat recovery unit is the major energy consuming station.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
