New Laboratory Methods for the Practical Assessment of Solid Fuel Characteristics in Large Furnaces

J. Wadenbäck, M. Berg, N. Padban & J. Zelkowski
With more suitable and accurate methods for characterizing all solid fuels future problems in power plants may be avoided. The methods described here focuses on grindability¬, ignitability/burnout¬and sintering properties simulating conditions in full¬scale furnaces. Grindability properties are assessed with a laboratory mill. (1) A solid fuel is ground in the mill. (2) Resulting ground material is separated into a dust fraction with the required fineness, and a coarser fraction recirculated to the mill. (3) New...
