Biomass fuel is a new type of green energy. It is a new energy fuel that uses straw, wood chips, branches, etc. as raw materials and is made into columnar particles by high temperature and high pressure special machines. Compared with traditional fossils such as coal, oil and natural gas. Energy has the advantages of being clean, cheap and renewable. Biomass fuel gasification boilers use 100% of biomass energy pellets as fuel. The boiler's combustion output is in line with national standards. The indicators of residual emissions are in line with national environmental protection standards, especially nitrides and Sulfide emissions are close to zero. Its burning cost is equivalent to ordinary coal, which is 1/2 of gas, 1/3 of oil and 1/5 of electricity.
After two years, Huludao Huadong Boiler Factory independently developed biomass fuel fuel and biomass fuel boiler biomass fuel gasification series boilers, which filled the gap in the country and attracted great attention from all parties. It has been listed as a national and provincial key environmental protection practical technology project by the China Environmental Protection Industry Association and the Liaoning Provincial Environmental Protection Bureau. It has been listed as an environmental protection product by Shenyang and Huludao Environmental Protection Bureau. The products are sold well in Northeast China and North China, and are well received by users. Favor. In April 2007, as the Olympic Games city of Shenyang, its environmental protection departments at all levels decided to change more than 200 loose coal boilers in the urban-rural integration department into biomass fuel gasification boilers before 2008. To this end, in June 2007, the Shenyang Municipal Environmental Protection Bureau, the National Development and Reform Commission, the Economic Commission, the Agricultural Economic Commission, and the Quality Supervision Bureau jointly issued the Notice on Promoting Biomass Fuels and Supporting Furnaces. Recently, domestic experts from various fields have highly praised this new type of product independently developed by Huadong Boiler Factory in Huludao City, Liaoning Province, and can be identified as a new bright spot in the development of regional circular economy. In this regard, "China Environment News", "Shenyang Evening News" and Shenyang TV station reporters conducted in-depth interviews and on-site reports, some enthusiastic people in environmental protection, energy conservation, published positive comments on relevant domestic websites and forums.
According to director Cui Guijuan, biomass fuel and biomass fuel gasification boilers are the best alternative to coal, oil and electric boilers, helping to save energy and improve the environment, and providing new areas for rural and farmers. The point of economic growth. According to the calculation of the relevant departments of Huludao City where the factory is located, only 30 processing points set up by the enterprise in the rural area can increase the income of farmers in the city by 100 million yuan, and increase the income of related industries such as animal flow and mechanical and electrical products production and operation by 200 million yuan. Yuan, so its development prospects are particularly impressive.

Huludao successfully developed biomass fuel and gasification boiler
In 2007, “Six-Five World Environment Dayâ€, Hualuo Boiler Factory in Huludao City, Liaoning Province accepted the warm invitation of Shenyang Yuhong District Committee, District Government and District Environmental Protection Bureau, and participated in the promotion of biomass boiler work in the Environmental Protection Bureau of Yuhong District, Shenyang City. On-site meeting. The site will conduct on-site furnace testing of biomass fuel and biomass fuel gasification boilers that are “non-combustible coal, non-burning carbon energy-saving and emission reductionâ€. The excellent output, energy saving and emission reduction effects have been met by the participants. Praise, dozens of enterprises and institutions on the spot signed a purchase agreement with East China Boiler Factory.
