The invention discloses a novel hearth structure of a biomass chain boiler. The novel hearth structure of the biomass chain boiler comprises a chain grate, wherein a front arch, a middle arch and a rear arch are sequentially arranged above the chain grate from front to back; the middle arch consists of a vertical flame turning wall; the rear arch comprises a vertical decorated wall and a transverse wall; the transverse wall is arranged on the rear side of the bottom of the decorated wall and transversely extends front and back; an arch top is arranged between the front arch and the middle arch, and an arch top is arranged between the middle arch and the rear arch; a first combustion chamber is formed between the front arch and the middle arch; a second combustion chamber is formed between the middle arch and the rear arch; a vertical rear boiler wall is arranged on the rear side of the rear arch; the decorated wall, the transverse wall and the rear boiler wall enclose a third combustion chamber. According to the novel hearth structure of the biomass chain boiler, a hearth can be effectively matched with the chain grate, an air power field in the boiler is organized, the combustion efficiency is improved, and the problems of ash deposition and slag formation in the biomass combustion process are mitigated.
