Abstract

The invention provides a biomass briquette fuel. The biomass briquette fuel is formed by mixing biomass raw material particles with fuel additives, and then crushing, mixing, drying, extruding and granulating; the weight percentage of the biomass raw material particles is 90-95%; the weight percentage of the fuel additive is 5-10%; the biomass raw material particles are composed of saw dust, bamboo dust, straws and rice straws; and the fuel additives are composed of quick lime, a combustion improver and high clay. The biomass briquette fuel is low in dust content which is greatly lower than the dust content of the fuel coal, and also high in combustion value and advantageous for improving the efficiency and the output of a boiler.

Description

technical field [0001] The invention belongs to the technical field of biomass energy utilization, and in particular relates to a biomass briquette fuel. Background technique [0002] At present, coal-fired boilers dominate my country's industrial boilers, and low fuel costs are a major advantage of industrial coal-fired boilers. According to decades of practical experience, coal-fired boilers have two unavoidable disadvantages: first, the thermal efficiency of the boiler is low, generally around 70%, and the fuel combustion is insufficient; second, the blackness of the flue gas is large, and the SO 2 , NO X High content, serious environmental pollution. As the country and the government's energy-saving and emission-reduction measures have been strengthened step by step, the Shanghai Municipal Government has implemented the energy-saving transformation of industrial boilers with fuel oil and gas instead of coal-fired boilers last year. How to ensure their own economic ben...
