14-05-2010· For fossil fuels (i.e., coal, fuel oil, diesel oil, LPG or natural gas), the flue gas specific heat can be assumed to be 1.02 to 1.03 kJ/(kg ·°C) which is equivalent to 0.25 Btu/(lb·°F). If you are using some other fuel, then you will need the flue gas composition as noted by Michael Reid's response. 2nd March 2009, 7:09 #4
The fuel is considered to be Standard Natural Gas (1040 Btu/std. ft3), the fuel consumption is 100,000 Btu/hr (HHV Basis), and the heat delivered to the home is 80,000 Btu/hour. The percent excess air for this combustion system is 10 %. The combustion air is drawn from the home at 70 F and 35 % Relative Humidity.
The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas.

· PDF fileThe available heat is defined as the amount of heat remaining in heating equipment (i.e. furnace, oven, boiler, heater, kiln etc.) after the heat contained within flue gasses and other losses are subtracted from the total heat supplied to the
16-04-2004· As far as computing the sensible heat or mean specifc heat of the flue gas for high gas temperatures, such as adiabatic flame temperature- at high temps over 2200F there is s significant departure from linearity due to dissassociation, ionization and generation of new species- the best method is to obtain a chart of sensible heat as a function of temperature for typical gas mixtures â€¦
