The optimal use of fuel energy and water in a fire tube boiler is important in achieving economical system operation, precise control system design required to achieve high speed of response with no overshot. Two artificial intelligence techniques, fuzzy control (FLC) and geneticfuzzy control (GFLC) applied to control both of the water/steam temperature and water level control loops of boiler. ...

An Industrial boiler is considered as highly energy intensive equipment. The primary objective of this study to identify and quantify the potential losses different sections fire tube its overall performance. Several saving measures such combustion optimization, excess air control, control flue gases temperature effect excessive or uncontrolled steam blow down on performance are also applied. E...

PROCESS AND TECHNOLOGY STATUS – Combustion boilers are widely used to generate steam for industrial applications and power generation. While all kinds of energy sources fossil fuels, biomass, nuclear and solar energy, electricity can be used to generate heat and steam, the scope of this brief is limited to combustion boilers using fossil fuels and biomass. Boilers can be grouped into two broad ...

The research aims to design and construct a new mixed vertical boiler (fire tube – water tube) with three gas passes. strength of this technological innovation is in the best use thermic transmission receiving fluid (hot water, steam, thermal oil), due its multipurpose function steps using alternative fuels (Diesel, Liquid Petroleum Gas LPG, natural gas), by improving efficiency temperature red...

National Thermal Power Corporation (NTPC) has signed an MoU with Bhabha Atomic Research Centre (BARC) for design and development of automated boiler tube inspection system for vertical water wall tubes. A vertical climbing robot has been developed for this purpose at Division of Remote Handling & Robotics (DRHR), BARC. Recently, an Electromagnetic Acoustic Transducer (EMAT) has been integrated ...

Fe-2.25Cr-1Mo a widely used material for headers and steam tubes of boilers. Welding of steam tube to header is required for production of boiler. Heat affected zone of the weld can have poor mechanical properties and poor corrosion behavior leading to weld failure. The cost of material used for steam tube and header of boiler should be controlled. This study propose a new materials design for ...
