Steam Boiler - Definition, Working Principle, Types, and Applications

A steam boiler is a power generation device, used for generating steam by applying the heat energy to water. The pressure range of earlier boilers ranges from low pressure to medium pressure (7 kPa to 2000 kPa/ 1psi to 290 psi). The present boilers are more useful because it works with high …

Boiler Efficiency Improvement & Heat Loss Explained in …

2020/7/3 · Bottom ash from the boiler is generally at a high temperature and has a lot of sensible heat. This heat can be utilized to preheat the air or water used in a boiler . The optimum ratio of fuel to air and keeping the excess air as low as possible keeping in mind the complete combustion of fuel can increase the furnace temperature thereby increasing the radiation heat.

Water Handbook - Boiler Feedwater Deaeration | SUEZ

only a small quantity of steam must be vented, because most of the steam used to scrub the water is condensed and becomes a part of the deaerated water. In order to deaerate the boiler feedwater, water is sprayed into a steam atmosphere. This heats the water to within a few degrees of the temperature of the saturated steam.
