Is biomass fuel a highly polluting fuel and can biomass boilers be used in the city? According to the environmental protection requirements and implementation standards, the Ministry of Environmental Protection of China has responded. The original text is as follows:
I. The use of agricultural and forestry waste (stalks, rice husks, sawdust, branches, etc.) as raw materials and processed by special equipment under specific process conditions to produce rod-shaped, block-shaped or granular biomass molding fuels can effectively improve agriculture and forestry The combustion performance of wastes is low in sulfur, nitrogen and ash content. It can be used in supporting special combustion equipment to achieve clean and efficient combustion. It produces less sulfur dioxide, nitrogen oxides and soot, and is not a highly polluting fuel. .
II. The promotion and application of biomass molding fuel in cities should fully consider the local environmental air quality control requirements and the actual situation of fuel supply. When the city’s gas supply can not meet the demand, biomass molding fuel can be used as an alternative fuel and should be required by the gas emission standards; the promotion and application in the metropolitan central area should be scientifically demonstrated and more stringent Requirements for air pollutant emission control.
3. In the promotion and application work, the supervision and management of the production and use of biomass molding fuels should be strengthened, and local standards and technical specifications for biomass molding fuels and supporting special combustion equipment should be formulated to regulate their production and use. During the application process, Pay attention to monitoring whether dioxins are produced; the units that produce and sell biomass molding fuel and supporting special combustion equipment should have corresponding qualifications, and the products must be certified by relevant management departments such as quality, safety, environmental protection and energy saving, and comply with relevant technologies Regulations and standards.
Protecting the environment is a basic national policy of our country. Taking the road of sustainable development has become the basic strategy of China’s economic and social development. In order to further implement the Law of the People’s Republic of China on the Prevention and Control of Air Pollution, the Law of the People’s Republic of China on Energy Conservation, and the Interim Regulations on the Safety Supervision of Boiler and Pressure Vessels, and in accordance with the requirements of the comprehensive improvement plan for the atmospheric environment, natural person boiler manufacturers have strengthened the prevention and control of gas pollution. And boiler energy-saving work. Its biomass boiler has achieved the requirements of low-carbon environmental protection.
The biomass fuel boiler replaces the coal-fired boiler, which helps to save energy and improve the environment. It has been listed as a key environmental protection practical technology project by the Ministry of Environmental Protection and China Environmental Protection Industry Association.
1. Boiler is a kind of energy conversion equipment. The energy input to the boiler is chemical energy and electrical energy in the fuel, and the boiler outputs steam, high temperature water or organic heat carrier with certain thermal energy. The original meaning of the pot refers to the water container heated on the fire, the furnace refers to the place where the fuel is burned, and the boiler includes the pot and the furnace.
2. The hot water or steam generated in the boiler can directly provide the required thermal energy for industrial production and people’s life, it can also be converted into mechanical energy by steam power devices, or mechanical energy can be converted into electrical energy by generators. Boilers that provide hot water are called hot water boilers and are mainly used in daily life. There are also a few applications in industrial production. The boiler that generates steam is called a steam boiler, often referred to as a boiler, and is mostly used in thermal power stations, ships, locomotives, and industrial and mining enterprises.
