Feb 01 2017 · In this article flue-gas aerosol from a large scale pulverized coal-fired power plant boiler is investigated. The power plant combusted various mixtures of coal and two types of wood pellet. Special attention is paid to the particle number size distributions total particle number concentration and chemical composition of particles in the ...

• ### ANALYSIS OF FLUE GASES - Project Gutenberg

The weight of flue gases resulting from the combustion of a pound of dry coal will be the sum of the weights of the air per pound of coal and the combustible per pound of coal the latter being equal to one minus the percentage of ash as found in the boiler test. The weight of flue gases per pound of dry fuel may however be computed directly ...

• ### How To Calculate Natural Gas Boiler Consumption--ZBG

The boiler gas consumption calculation need the following parameters: such as natural gas calorific value 8500kcal/m3 pressure 8-10Kpa and theoretically the gas consumption of boiler heat = boiler calorific value÷ (Calorific value of natural gas x Boiler thermal efficiency )= 2400 000 Kcal / (8500Kcal * 0.94) =297m3/h here we take 4 tons of natural gas boilers for example then the boiler gas

• ### CO Measurement in Coal Fired Plants | Yokogawa America

The amount of excess air in the flue gas is determined by measuring the concentration of oxygen (O 2). The ideal excess O 2 level (the lowest possible that allows complete combustion) depends on several factors: the fuel type the burner type humidity changes in the air moisture content changes in the fuel varying boiler loads fouling of the burner system and mechanical wear of combustion equipment.

Assuming that flue gases contain only these two gases the losses [kW]can be calculated as: L1 = m& CO H l CO + m& H 2 H l H 2 (9) where m& CO is the mass flow of carbon monoxide [kg/s] m& H 2 the mass flow of hydrogen H l CO the lower heating value (LHV) of carbon monoxide (1012 MJ/kg) and H l H 2 the lower heating value (LHV) of hydrogen (1195 MJ/kg).
