Coal elevator is used for conveying coal into coal bin, then the coal is transported into hearth by stoker. In pyrolysis section of the furnace, the coal is dried and carbonized. The Coal will move downwards slowly with temperature increasing and come to gasifying section after 8 to 10 hours. All the water in coal is released, tar and most sulphide are carbonized out and hydrocarbons produced, which forms up gas; While down gas is produced by gasification reaction of semi-caking coal which is gasified.
Discharge up gas comes into electrostatic tar separator from tar preremover, where tar carried by the gas is removed, then the gas comes into electrostatic precipitator after mixing with the gas in the lower zone.
The gas in the lower zone comes into heat exchanger after being removed most dust by cyclone separator, it mixes with up gas and fine dust and part light oil in gas are is removed by electrostatic dust separator again. Then the gas comes into indirect cooler to be cooled to normal temperature. Finally the gas is transported to its consumption place after pressurized with gas compressor.
Tangshan Keyuan Environmental Protection Technology & Equipment Co., Ltd which was established in 2004 is specially engaged in the development, manufacture, sale and service of coal gasifier and relevant purifying equipment, gas desulphurization system, online detection system, combustion equipment and phenol water treatment system. The products have been successfully applied in the field of metallurgy, ceramic, glass, nonferrous metals, chemical industry and refractory materials, etc. and have been sold at home and abroad, like india, south korea, Austrilia and many other Southeast Asia country. Keyuan has been recommended the tiltle of China-Asean faminous brand by China-Asean Business Council.
Our has been granted the title of Hebei Provincial Scientific and Technological Enterprise and High-Tech Enterprise by STD of Hebei Province is the Council Member of Hebei province high and new technology industry association and Tangshan equipment manufacturing industry association and member of Hebei province environmental protection industry association. Keyuan Company has always been committed to the field of development and manufacture of coal gasification and related products; we melt the most effective energy-saving and environmental protection technologies into the R & D of products to offer the clients the optimized fuel supply solution. As the outstanding achievements in the field of energy saving and environmental protection, keyuan company has been awarded Energy-saving China Contribution Award by China Energy Conservation Association in 2010.
Keyuan Company owns Tangshan Coal gasification Engineering Technology Research Center which is approved by Tangshan STD and has a dynamic and innovative R & D team, on the basis of close cooperation with the universities and research institutes of Tsinghua University, China University of Mining and Technology, University of Science and Technology Beijing, Hebei Polytechnic University, North China Municipal Engineering Design & Research Institute and Sinoma Suzhou Design & Research Institute Of Non-metallic Minerals etc. Taking market-based, collaboration and innovation as the purposes of research and development, we have made intensive study and continuous improvement of various types of coal gasifier and successively developed a series of new types of single-stage coal gasifier, double-stage coal gasifier and pyrolysis coal gasifier, as well as gas purifying equipment, gas desulphurization system, online detection system, combustion equipment and phenol water treatment system. We have a number of independent intellectual property rights of key technologies in the field of coal gasification and other related fields. The pyrolysis coal gasifier has been identified as environmental products for three times continuously by Hebei Environmental Protection Industry Association since 2007 and been widely promoted. The energy-saving and environmental protection type gas station is well-received by the client and has gotten the honorary title of excellent green demonstration project of energy saving and environmental protection industry in the eleventh China International Science and Technology Industry Exposition. Phenol water treatment technology is the support plan of tangshan science and technology which is promoted and supported as key energy conservation and environmental protection technology.
It took the lead and was certificated by ISO9001 Quality Management System. Some products were certified by the CCC National Mandatory Product Certification. We strictly abide by the quality policy of improvement and perfection and insist on the enterprise guideline of human-centered and creditability, in order to provide the clients with the most professional-quality products and fast, high-quality services to assist their success on the business.
