The invention relates to a low-temperature generating method and generator, which uses horizontal chimney and multi-medium segmented heat exchange method to reduce the heat loss that exhausted to the air, to improve the utilization of fuel; in the process of generating via steam, it uses multi-medium stepped temperature decrease and fluidifying and medium temperature decrease stepped feedback generation to release the gasified heat to generate, to reduce the heat loss in said process, to improve the coal-electricity transformation rate. |
