Pressurised Fluidised Bed Combustion System (PFBC): Pressurised Fluidised Bed Combustion (PFBC) system is used for large coal burning applications. The operating efficiency of PFBC is increased by introducing differential air pressure. In PFBC, coal is…

Circulating Fluidized Bed Combustion System (CFBC): The Circulating Fluidized Bed Combustion System (CFBC) has evolved from conventional bubbling bed combustion to over come some of the drawbacks associated with bubbling bed combustion. CFBC provides greater…

Bubbling Fluidized Bed Combustion System: In Bubbling Fluidized Bed Combustion System (or) Atmospheric bed combustion system, coal is crushed to a size of 1 - 10 mm depending upon the quality of coal and type…

Fluidized Bed Combustion Boiler Working and Types: The coal available in India is of low quality, high ash content and low calorific value. The traditional grate fuel firing systems have got limitations and are techno-economically…

Velox Boiler - Construction, Working Principle and Advantages: Velox Boiler - When the gas velocity exceeds the sound velocity, the heat is transferred from the gas at much higher rates than rates achieved with sub-sonic…

Loeffler Boiler Construction and Working Principle: The major disadvantage in La Mont boiler is the deposition of salt and sediment on the inner surface of the water tubes. It reduces the heat transfer and ultimately…

Benson Boiler - Construction, Working Principle and Advantages: In 1927, Benson boiler was developed by Benson in West Germany. It was the first super critical drumless boiler. Construction: It is a high pressure, vertical, fire…

La Mont Boiler Construction and Working: This type of boiler was introduced by Lamont in 1925. The arrangement of La Mont Boiler Construction and Working is shown in the Fig. 1.30. It is a forced…
