Využití tepla odchozích spalin z kotle pro ohřev vody

Abstract

This thesis focuses on the theoretical analysis of boilers with granulating fireplace for hard coal combustion. The thesis also describes dew point of combustion products which is important from the viewpoint of corrosion of the boiler heat exchanger. The research of boilers with granulating fireplace is described in detail. Stoichiometric calculations for the specified fuel (hard coal) are performed to the calculate of heat exchanger and the calculation of boiler efficiency is performed. There is proposal of heat exchanger of type combustion product - water is done in the calculated part of thesis. Dimensions of the exchanger, the thermal performance and water of heated water are determined. In consclusion assessment of heat exchanger alternatives is performed.
