Energy and exergy analyses of natural gas-fired boilers in a district …

2017/7/5 · Abstract. In this study, energy and exergy analyses of natural gas fired boilers in a district heating system are performed. Mass, energy and exergy balance equations are formed for the boilers and its components. In the boilers, energy or heat losses are examinated, and the biggest of these is identified as the heat loss of flue gases.

Energy and exergy analyses of a mass-fired boiler for a proposed …

2018/7/25 · In the energy analysis, as illustrated in Fig. 10, the energy losses of the mass-fired boiler was mainly due to the flue gas, bottom ash, surface heat loss, and blow-down water. Total energy loss ratio was found to be 21.3%, which the both flue gas sensible and latent heat losses were the greatest ratio in the studied boilers with 20.2%.
