COMBUSTION - tnp-instruments.com

2014-2-15 · Combustion takes place when fuel, most commonly a fossil fuel, reacts with the oxygen in air to produce heat. The heat created by the burning of a fossil fuel is used in the operation of equipment such as boilers, furnaces, kilns, and engines. Along with heat, CO 2 (carbon dioxide) and H 2 0 (water) are created as byproducts of the exothermic

Experimental investigation on flue gas emissions of a

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.
