Highlights of biomass boilers

17 Jan, 2022

  It is understood that in recent years, the price of fossil fuels in the global market has been rising, and in many factories and enterprises that need fuel, the cost of material resources is increasing. In addition to petroleum fuels, people have turned their attention to biomass pellet fuels and other bioenergy fuels. Although biomass fuels have not been effectively promoted, it is believed that with the promotion of biomass boilers, fuels will become common.

  It is understood that in recent years, the price of fossil fuels in the global market has been rising, and in many factories and enterprises that need fuel, the cost of material resources is increasing. In addition to petroleum fuels, people have turned their attention to biomass pellet fuels and other bioenergy fuels. Although biomass fuels have not been effectively promoted, they have not been effectively popularized. With the understanding of biomass pellet fuel, biomass fuel will definitely replace some non-renewable energy fuels in the future.

  It is reported that there are currently more than 500,000 industrial boilers in my country, and the annual coal consumption is about 1/3 of the country's total coal consumption. The environmental pollution caused by coal-fired industrial boilers is very serious, and a large number of industrial boilers must be replaced with clean energy. According to my country's biomass resource conditions, the use of agricultural and forestry residues as boiler fuel is environmentally friendly and renewable. Research on biomass combustion technology for industrial boilers and development of biomass fuel boilers will save conventional energy and optimize my country's energy structure. Reducing environmental pollution has positive significance.

  Biofuels can not only reduce costs, but also reduce environmental pollution. Straw fuel is a kind of biofuel. It uses a straw fuel pellet machine to make sawdust, corn stalks, peanut shells, straw, cottonwood stalks, branches, edible fungus waste and cow dung into high-density, combustible, high-quality pellets. . Biomass-fired boilers treat "waste" with "waste" and become a new direction of zero carbon emission, environmental protection and energy saving. It is understood that biomass fuel boilers are designed for waste in various processing industries, and the main fuels include waste wood, rice husks, corn cob, etc. According to incomplete statistics, only 12 million tons of biomass can be used every year in Zhejiang Province, China. If all of them are used, it is equivalent to saving 6 million tons of standard coal every year. At present, most of such surplus materials in China have been disposed of disorderly, which is a pity. Biomass fuel boilers can not only process waste, but also reduce fuel costs, zero carbon emissions, and generate environmentally friendly new energy, which has attracted widespread attention.

  The biomass boiler adopts the most suitable combustion equipment for biomass fuel combustion - reciprocating grate. In terms of structural design, the boiler has a larger furnace space than traditional boilers, and at the same time, a very reasonable secondary air is arranged, which is conducive to the full combustion of a large amount of volatile matter that is instantly precipitated when biomass fuel is burned.

  Due to the limitations of electricity, natural gas supply and gas pipelines, it is currently impossible to change all coal-fired boilers in my country to electric boilers or gas-fired boilers. The low price and low operating cost of biomass boilers are easier for users to accept and promote, which just fills the gap. this blank. Biomass pellet fuel is widely distributed in our country with its raw materials and advanced processing technology. Biomass pellets are known as green coal and are a kind of clean energy. As the fuel of the boiler, it has a long combustion time, high temperature of the intensified combustion furnace, and is economical. At the same time, it has no pollution to the environment, zero CO emissions, zero SO emissions, and is a renewable energy source.

  Recycling, can replace wood, coal, natural gas. And the running cost is only half of gas. A large number of raw materials produced by agriculture in my country provide a strong material guarantee for the promotion of biomass boilers. It can not only solve the problem of straw burning for farmers, but also make full use of resources. The burned ash is a very good fertilizer.

biomass boilers

  At present, biomass boilers are roughly divided into two categories according to their uses: one is biomass thermal energy boilers, and the other is biomass electric energy boilers.

  In fact, the principle of the two is basically the same, both obtain energy by burning biomass fuel, but the first one directly obtains heat energy, and the second one converts the heat energy into electricity. Among these two kinds of boilers, the first one is the most widely used and the technology is relatively mature.

  Biomass boilers mainly have the following four advantages:

  One furnace can be used for heating, cooking, boiling water and bathing at the same time; super conversion system. Low start-up heat transfer temperature, fast heat transfer speed; low installation cost, safe heating: common equipment, no change to the original heating equipment, common pipes and radiators, using water circulation to achieve a wide range of heating materials, never exhausted, available everywhere (such as: chaff, corn stalk, rice stalk, wheat); safety and environmental protection: low work pressure, cooking, boiling water, bathing, heating, etc., but also suitable for boilers, greenhouse heating, large-area heating, small and medium-sized restaurants. Not limited by season, can be used all year round

  Biomass boilers are a potential product in the boiler industry. Only by correctly understanding biomass boilers can we actively guide the development of the boiler industry.
