Abstract:
     According to this invention, poor-quality coal or coal gangue is used to generate combined gas with low thermal value. This gas generator is a circular construction made of ordinary and refractory bricks. Its kiln channel is an enclosed ring around the generator and baffle plates are arranged for segmenting the channel. In the channel, the gasifying sequence of coal as raw material is oxidation, reduction, dry distillation and drying. This gas generator features high power of heat accumulation and convenience for dregs exhaust.
