Abstract

The invention relates to a method for forming biomass fuel by comprehensively utilizing straws. Formed biomass fuel which is formed and produced by pulverizing and squeezing the straws is thrown into a biomass direct-burning boiler, slag and ash obtained through the combustion of the formed biomass fuel are used as potash fertilizer fuel after being processed by a humidifying stirring packing machine, partial steam generated by the boiler is used for generating the power through a steam turbine and a generator, the generated electric power is inputted to an electric network, part of the low-grade steam obtained after the work of the steam turbine is pumped for supplying the heat, and the rest steam is condensed into water by a condenser to be used for the boiler after the working of the steam turbine. The biomass direct-burning boiler utilizes a water-cooling vibration grate boiler structure, the fuel applicability is strong, the straws can be fed into the boiler after being simply pretreated, nearly no abrasion exists, and effects of comprehensive utilization, high efficiency, low cost and cleanliness can be realized by improving the boiler structure.

Description

technical field [0001] The invention relates to a method for comprehensively utilizing straw to form biomass fuel. Background technique [0002] Biomass energy is the solar energy fixed on the earth by the photosynthesis of plants, which is a typical renewable energy source. The use of biomass energy to replace fuels such as oil, coal, and natural gas to produce electricity can reduce dependence on fossil energy, protect national energy resources, and reduce environmental pollution caused by energy consumption. [0003] my country SO 2 The emission space is limited, the country burns more than 700 million tons of coal every year, SO 2 emissions have reached the upper limit. Thanks to SO 2 pollution, acid rain has harmed 30% of the country's land area. In 2003, only acid rain harm caused the loss of agricultural and forestry crops as high as 22 billion yuan, SO 2 The pollution is even more dangerous to people's health. Since the sulfur content in biomass is only about ...
