Common Boiler Excess Air Trends and Strategies to Optimize

the stoichiometric air/fuel ratio, AFs. For natural gas, AFs is about 17.2 lbm-air/lbm-ng. The quantity of air supplied in excess of stoichiometric air is called excess air, EA. Excess air can be written in terms of the stoichiometric air/fuel ratio, the combustion air mass flow rate, ma, and fuel mass flow rate, mf.

analyses. The calculated flue gas flow is compared with the reference flue gas flow calculated from the elemental composition. It is shown that, for a wide range of coal and biomass compositions, the above formula performs very well. For light fuel oil the formula is: V God = 1.76435 + 0.20060 H (N) (m 3/kg) and for natural gas: V God

Experimental investigation on flue gas emissions of a

Feb 23, 2010 · Flue gas emission concentrations were measured by gas analysers. If the flow rate of the flue gas is known, quantitative analyses of the emissions could be done easily. When the biomass boiler is in operation at its design load with a flue gas O 2 concentration of 6%, the dry flue gas flow rate was estimated to be ∼550 l (at 15°C and 1 atm)/min.
