Particle Emissions from Small Wood-fired District Heating .

Particle and gaseous emissions of four different wood chip-fired district heating units in the size range 5−15 MW were studied. Three of the units were fire-tube boilers based on rotating grate combustion technology, and one was a gasification combustion boiler. All of the units were equipped with cyclones to remove coarse particles from the flue gas.
