A rotary airlock feeds the raw material to the hammer mill. A controller adjusts the air lock speed and the mass flow of the entering raw material. The material is ground between the rotating beaters and the housing. A fan generates a constant flow of air or hot gas and transports the ground product out of the mill housing into an air separator.

The correct pilot action for a hot start typically is to cut fuel off immediately and leave the starter engaged. Motor the engine long enough to purge all the fuel and hot gas from the combustor and allow airflow to cool the hot section. A hung start occurs when the engine starts but doesn't accelerate to idle speed.

Hot gas efficiency (HGE) is defined as the ratio between the sum of chemical energy and sensible heat of the produced syngas, on the one hand, and the sum of chemical energy and sensible heat of the feedstock fed to the plant, on the other hand. The hot-gas efficiency assumes that the heating of the unconverted char is a loss.
