Auxilary Boiler Fuel Consumption

How to calculate the gas consumption of the gas boilers

How to calculate the gas consumption of a gas boiler? Gas consumption = Gas boiler power /Fuel calorific value / Gas boiler heat value utilization For example we operate 1 ton gas boiler for 1 hour (full load) The boiler output is 600000 kcal (fixed value) the natural gas calorific value is 3622 MJ/Nm3 (fixed value) and the thermal efficiency is 92% (non-fixed value)

Auxiliary Power Consumption - an overview | ScienceDirect

The auxiliary power consumption of IGCC without CO 2 capture is expected to be around 15% of the gross power output while for CO 2 captured cases this is typically 2426% This is consistent with the findings in recent literature ( Prins et al 2012; Martelli et al November 2011; Gräbner et al 2010; Kunze and Spliethoff 2010; DOE/NETL-2015/1727 2015 )

16-Perfect reasons for more fuel consumption of Boilers

Increase in excess air causes dry flue gas loss & hence more fuel consumption And also leads to more auxiliary power consumption 5 Unburnt fuel or incomplete combustion of fuel leads to increased consumption of fuel Unburnt is due to improper air fuel mixture or unbalanced draught or variation in the fuel quality 6 Blow down water carries saturated
