FIELD: power engineering.
SUBSTANCE: proposed method is suited to burning not only coal but also other coal-containing materials and involves division of gasification process into two stages thereby making it possible to effectively combine high-speed process in swirling flow of dust-gas mixture and gasification in fluidized bed at excess air ratio lower than unity.
EFFECT: enhanced productivity of process and burn-up of components of various fuels.
