AIR & FLUE GAS PATH | Power4you - "Power from Knowledge"

Jan 24 2016 · Flue Gas Flow. After burning of coal it is converted into Fly Ash and Bottom Ash. This Fly Ash contain huge amount of heat energy. So we utilise that energy to increase the efficiency of boiler. In flue gas path we place boiler auxiliaries which increase the efficiency of boiler by absorbing the heat content in the Flue Gas.

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.
