BOILER EFFICIENCY CALCULATION METHOD OF LATENT HEAT RECOVERY BOILER

摘要

PROBLEM TO BE SOLVED: To provide a boiler efficiency calculation method calculating boiler efficiency of a latent heat recovery boiler easily and precisely.;SOLUTION: A calculation method of boiler efficiency of all of a latent heat recovery boiler with a can body and a latent heat collecting unit collecting heat of exhaust gas from the can body has a step using exhaust gas heat loss quantity of the can body calculated from heat of combustion air supplied to the can body and heat of exhaust gas from the can body and recovery heat of the latent heat collecting unit calculated from heat difference of heated fluid before and after passing the latent heat collecting unit, and subtracting recovery heat of the latent heat collecting unit from the exhaust gas heat loss quantity.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
