Waste heat recovery As energy efficiency grows even more important, the focus is widening from the production of thermal energy to the reuse of what already exists on board. Already the leader in waste heat recovery, Alfa Laval is expanding both the application and its potential for every vessel. Why let fuel go up in smoke?
Flue Gas Waste Heat Boiler Thermal Efficiency Calculation
Selnikel waste heat boiler system is an optimal solution for plants aiming to decrease their energy costs and to become more enviroment friendly by cutting down their harmful emissions. Waste heat recovery boilers are engineering solutions for generating steam, hot water, hot oil and hot air from gas turbines and motors exhaust gasses which are used to generate electricity. With this application, it is possible to increase the efficiency of a turbine or motor system from 40% up to 90%.
According to the system, the temperature of smoke discharged by the boiler can be reduced to be lower than the water dew point temperature through the smoke heat exchanger, the temperature of
colored smelting smoke waste heat boile outlet temperature. Waste Heat Boiler - an overview | ScienceDirect Topics. Heat absorbed by water = 0.95 Vs(t 1 t 2)MJ s 1. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in .
The anti-balance test method is usually used to measure boiler thermal efficiency. The calculation formula for the thermal efficiency of the anti balance method: η= 100- (q2+q3+q4+q5+q6) 1. q2-flue gas heat loss The exhaust heat loss is the heat loss caused by a part of the heat that is taken away by the smoke of the boiler.
