Raising of fuel utilization efficiency in the contact heat exchange boilers

Abstract

The relevance of the study is due to low effective utilization of heat of fuel combustion in existing heat generators, in particular, boiler units intended for heat supply to industrial enterprises and residential buildings. Another important research area of the study is the ascertaining ability of a boiler to operate on raw water, which hasn't undergone a process of preliminary reduction of hardness. The article reveals the use of latent heat of water vapor contained in the exhaust gases in all models of existing boiler units. The authors proposed and described a method for the effective utilization of the latent heat by means of contact heating of the coolant
