ABSTRACT:
An apparatus allowing the use of low-grade solid fuel powders (coal, lignite, peat) and products derived therefrom during cold starting periods and for backing up combustion chamber operation at low load. The pilot burner (1) has an auxiliary and pilot igniter which burns gas produced by gasifying low-grade fuel in a gasification unit (6) and a main igniter which burns the low-grade fuel powder in a storage silo (5). The combustion air is heated in an air heater (10) by the gas produced by gasifying low-grade fuel in gasification unit (6). In particular, turbulence is set up in the combustion air sent to the outlet of the pilot igniter. Application to combustion apparatus including steam generators of thermal power stations.
