Fermented biomass briquette coal and production method thereof

The invention provides fermented biomass briquette coal and a production method thereof. The fermented biomass briquette coal is prepared from the following raw material components in parts by weight: 150-250 parts of pulverized coal, 25-75 parts of sludge powder, 20-40 parts of biomass, 4-6 parts of a sulfur-fixing agent and 4-6 parts of a dust-fixing agent. The production method comprises the following production steps: (1) crushing biomass and mixing with water and a leavening agent, and fermenting for 7-10 days to obtain fermented biomass; (2) mixing the pulverized coal, the sludge powder, the sulfur-fixing agent and the dust-fixing agent together uniformly, and then adding the fermented biomass, and uniformly mixing; (3) performing cold pressing and molding, and naturally maintaining to obtain the fermented biomass briquette coal. The fermented biomass briquette coal disclosed by the invention not only has the advantages of low ignition point, high burn-off rate, relatively good thermal stability, and the like, but also has relatively high strength and relatively good waterproof performances. Moreover, the content of combusted soot pollutants is low.
