Biomass is used as a substitute for coal to provide heat. The new biomass-fired biomass fuel boiler is fueled with agricultural biomass fuel (granular, rod, block, etc.) as a fuel, and is supplied by a dedicated biomass-forming fuel boiler to provide renewable heat. It is forbidden to blend municipal solid waste, used furniture plates, industrial solid wastes, and other hazardous wastes, as well as fossil fuels such as coal and vermiculite. It is forbidden to directly use unformed biomass bulk materials.
The raw material that generates the biomass fuel must be agricultural and forest residues, including crop straw (corn stalks, rice stalks, wheat stalks, cotton stalks, oil crop stalks, etc.), agricultural product processing residues (peanut shells, rice husks, husks, sugar cane Slag, furfural slag, plastic bags to remove plastic packaging, etc.) and forestry "three remainings" (care residues, felling residues, processing residues). The biomass forming fuel has a crushing rate of no more than 5%, a moisture content of no more than 18%, an ash content of no more than 8%, a sulfur content of no more than 0.1%, and a nitrogen content of no more than 0.5%.
New forms of distributed heating for renewable energy Heating for biomass forming fuel boilers refers to the use of agricultural and forestry biomass feedstocks (crop crops, forestry residues, etc.) that are physically compacted to form rod-shaped, massive, granular shaped fuels in biomass. Burned in special boilers to generate heat for industrial and residential heating.
Biomass-fired boiler heating is a distributed renewable energy source that is green, low-carbon, environmentally friendly and economical. It is an important measure to replace fossil energy for heating and prevent air pollution.
In addition, biomass-molded fuels supply green, low-carbon, zero-carbon emissions. Biomass-forming fuel raw materials include crop stalks (eg, corn stalks, rice stalks, wheat stalks, cotton stalks, oil crop stalks, etc.), agricultural product processing residues (eg, peanut hulls, rice husks, bagasse, bacterium bags, etc.) and forestry. The "three remainings" (feed residues, felling residues, processing residues) are typical renewable energy sources. The conversion process is the synthesis of carbon dioxide and water into biomass through the photosynthesis of green plants, and biomass energy. The use of carbon dioxide and water generated in the process, in theory, zero emissions of carbon dioxide, green and low carbon.
Biomass Fuel Boiler Heating Demonstration Project Boiler Technical Level and Emission Requirements The boiler used in the biomass biomass heating boiler heating demonstration project should be a dedicated biomass boiler dedicated to the combustion of biomass-forming fuel. Large-scale projects should adopt advanced recycling. Fluidized bed boilers. Demonstration project shall be equipped with cyclone dust removal and bag dust removal secondary dust removal device, and install and run continuous monitoring system for smoke emission. For SO2, NOx can not be stable to meet the emission requirements, desulfurization and denitrification facilities should be installed.
Strictly control the emission of boiler air pollutants. According to the requirements of Guoneng Xinneng [2014] No.295 Document, the smoke, dust, SO2, and NOx emission levels of the demonstration project are respectively less than 30mg/m3, 50mg/m3, and 200mg/m3, and the emissions are further strictly controlled to reach or exceed Natural gas emission standards (provided that the reference oxygen content emission concentration is tentatively calculated at 9%; the height of the chimney refers to the natural gas standard, and the specific altitude is determined according to the approved environmental impact assessment document). For demonstration projects constructed in key areas, the concentrations of soot, SO2, and NOx emissions should reach the limits of natural gas emissions. For projects that have a high level of clean emissions, they should be included in the demonstration project.
Compared with conventional heat production and utilization methods, such as large-scale long-distance transport of fossil fuels, centralized construction of large-scale heating projects, and the layout of large-scale pipe networks, biomass heating boiler heating is a typical distributed heating system. The use of raw materials, local production, and local use directly replace coal-fired heating in the terminal consumer side. It has a decentralized layout, flexible operation, and strong adaptability to meet the diversified heat demand. It is an important content of the revolution in energy production and consumption.
