Determination of biomass concentration in an air coal dust flow of coal/wood particle power station

摘要

The process operates at the region of highest coal dust biomass concentration of the post milling flow (12). A partial flow (22) is diverted to a sample collection device (7), where the coal dust and biomass are separated in a known manner and the flue gas (23) is fed back to the suction side of the milling plant (1). A blocking disk (15) can be used to shut off the sample flow (22). The sample collection channel is connected by a union piece to the sample collection device (17) and a separating device for recycling the flue gas (23).
