The maximum transfer of energy from fuel to steam shows better performance of boiler. If a boiler has good combustion system, which converted the fuel energy into thermal energy more thermal energy will be produced from the available fuel energy. If the boiler's heat transfer system is efficient, a maximum portion of generated heat will be absorbed by water during the generation of steam.Learn More

Boilers. Boiler is a system which transfers the energy from the fuel to water. The boiler fuel will be combusted and the thermal energy generated will be transferred to the feed water. The water gets heated up and hot water or steam will be generated. The maximum transfer of energy from fuel to steam shows better performance of boiler.Learn More

Boiler is a closed vessel in which water is converted into steam by the application of heat. Usually boilers are coal or oil fired. A boiler should fulfill the following requirements (i) Safety. The boiler should be safe under operating conditions. (ii) Accessibility. The various parts of the boiler should be accessible for repair and maintenance.Learn More

A research program was undertaken to study the feasibility of employing steam washers to control silica deposition in high-pressure turbines. Under certain laboratory conditions, steam washing was found to be effective; however, its useful application appears to be limited to a very small number of power stations.Learn More
