Flue gas filtration of biomass boilers. Dedusting and filtration of flue gases from a coal or biomass boiler is a very important topic due to the increasingly stringent requirements for the discharge of solid pollutants into the air. Most of the operated biomass boilers, mostly of older production date, are equipped only with cyclone separators or multicyclones.
Feb 23, 2010 · In order to measure the flue gas composition and emissions, a stainless water-cooled sampling probe was made and used to sample flue gases at the exit of the boiler, i.e. at the inlet of the chimney after the water heat exchanger of the boiler. Main composition of the flue gas (CO 2, O 2, CO) was continuously measured by an ABB continuous gas analyser equipped with a non-dispersive …
Twinning Biomass Boilers Page 5 The twinning of biomass boilers into one flue should only be designed and installed by a competent chimney specialist in accordance with BSEN 13384-2:2003+A1:2009, and with the approval of the boiler and flue manufacturers. The installation must also
Since biomass fuels are primarily composed of carbon, hydrogen and oxygen, the main products from burning biomass are carbon dioxide and water. Flame temperatures can exceed 2000°C, depending on the heating value and moisture content of the fuel, the amount of …
Chlorine. Chlorine is a major factor in ash formation. and corrosion. It facilitates the movement of inorganic. compounds in particular potassium. Potassium chloride. is one of most stable high temperature, gas-phase, alkali. containing species, hence is the prime cause for corrosion. in boilers.
The Grant biomass flue system has been engineered to cope with continuous operating temperatures up to 200°C although the typical flue gas temperature produced by the Spira are much lower than this. The system is designed so that the stainless steel outer case is load bearing and stainless steel inner liner is free to expand independently to
