Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

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.

Wedge Heat Insulation Materials & Systems
Improved solutions to heat problems are constantly required in most
applications and processes starting from (-) 60 °C to 1750 °C to improve
operational performance and durability of equipments, reduce heat loss,
save energy, save space, and protect environment.
Finding heat insulation system with highest insulation performance
(lowest thermal conductivity), high mechanical strength, high service
temperature, easiest application, long lasting, and lowest cost is almost
impossible. However, thanks to the modern insulation technologies and
latest developments in combining wide range of technical properties
making it available a wide range of insulation materials & systems to
achieve optimized high performance at low cost and long lasting
insulation systems at extremely low maintenance cost.
Heat insulating materials usually have a total porosity of at least 45%, in
practice mostly from 60 to 90%, and in extreme cases up to 99%.
Besides low thermal conductivity, high porosity causes reduced
mechanical strength, high gas permeability and low corrosion resistance.
The thermal conductivity not only depends on the total porosity of the
material, but also on the pore size and shape, the structure composition
and the mineralogical composition.
Depending on temperature, the factors responsible for the flow of heat –
solid state conduction, convection and radiation – vary in influence.
Maximum pore diameters of < 1 mm are necessary. Micro -porous
insulating materials with pores < 0.1 μm have the lowest thermal
conductivity.
Wedge SSPL manufactures and offers wide range of Insulation materials
& systems designed in-house, manufactured with high quality raw
materials, and fabricated to highest precision. Our insulation materials
are most suitable for all types of surfaces straight and cylindrical.
Wedge Insulation systems satisfy the demand for optimum planning,
thermal profiles, ready to use shapes, lower thickness, easy
installation, high insulation performance, long life, and lower
maintenance cost.
Our wide range of insulation products include: Microsilica, Fumed
Silica, Nano-porous, Microporous, Millboards, Magnesium Silicate,
Calcium Silicate, Perlite, Vermiculite, Refractory Fibre Cement,
Ceramic Fibre, Glass Wool, Slag Wool, Foam Glass, Aerogel, Vacuum
Insulation.

Microporous Insulation Flexible Matress
Microporous insulation boards are manufactured by mixing high quality agglomerates of pyrogenic silica and selective grade
opacifiers along with filaments and pressed at a very specific pressure range to achieve a very narrow range of optimum highest
possible porosity and unique range of densities to deliver a product with lowest possible heat loss through conduction, convection,
radiations, and gaseous conduction. The thermal conductivity of Microporous insulation is lower than the still air at high temperatures.
Advantages

Perlite Insulation Boards & Pipe Sections
Wedge Perlite insulation board, also known as waterproof perlite insulation board, is made of expanded perlite bulk material as
aggregate, adding waterproofing agent and binder for preparation, screening, pressure forming, drying processes. Expanded perlite
is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 6mm in size. It is
inorganic, inert, neutral in pH, biologically stable and has no asbestos content. It has excellent thermal insulation properties over
an extremely wide temperature range from cryogenics at minus 273°C (absolute zero) up to refractory applications at over 1000°C.
It also has a highly adsorbent surface and a very low bulk density which makes it an ideal carrier or low cost filler for many compound
formulations.
Perlite Insulation products have the benefit of containing a rust inhibitor which is activated if the insulation comes into contact with
moisture. The inhibitor neutralises any chlorides present, thereby greatly reducing, if not totally eliminating, corrossion under
insulation (CUI).
Advantages
• Light weight with very low bulk density.
• Waterproof with extremely high hydrophobicity.
• Low thermal conductivity.
• Most suitable for cryogenic applications -190°C.
• High temperature insulation up to 650 °C.
• Fireproof, rot proof, damp proof, sound proof.
• Construction safety is simple and easy, roof and wall.
• Environmentally friendly.
• Water repellent, non-flammable, loose-pour insulant improves the
thermal performance on masonry walls and floors.
• Corrossion under insulation (CUI) resistant.
Applications
• High temperature insulation and heat protection
• Cryogenic application: Non-combustible ultra-lightweight mineral
aggregate with excellent insulation & adsorption properties.
• Fire proofing and sound proofing.
• Swimming pools, cold storage, boilers and some insulation projects
with special requirements for waterproofing.
• Perlite insulation is used in high temperature applications in the steel
and foundry industries such as ladle topping, hot topping and riser.
• Expanded Perlite is suitable for a range of landscaping applications such
as green roof construction, golf green renovation and construction,
planters, drainage.
• Expanded perlite powder and board is a hydrophobic insulating aggregate.
