Large-scale cracking furnace burner industrial application test project uses advanced technology to develop the design of the bottom burner, flame flat and rigid, stable combustion, nitrogen oxides (NOx) emissions and noise values ​​are better than the national environmental protection standards, combustion performance Better than foreign similar products, can fully meet the process heat flux requirements. This achievement has succeeded in realizing the localization of domestic new and rebuilt combustion systems for ethylene cracking furnaces, and has changed the long-term reliance on imports from the bottom combustion systems for large-scale ethylene cracking furnaces in China. This new device has been successfully applied in the national “Eleventh Five-Year†key construction project—Tianjin One Million Ethylene Cracking Furnace, which has extremely high promotion and application value.
It is understood that the combustion system as an important part of the ethylene cracking furnace, its advantages and disadvantages are directly related to the long-term safe and stable operation of the cracking furnace. With the increase in the size of the furnace and the increase in environmental protection requirements, higher requirements have been placed on the burner flame length, flame shape, heat flux distribution in the furnace, and NOx emissions. Tianhua Chemical Machinery & Automation Research and Design Institute is the main organization for the research and development of ethylene cracking technology and equipment in China. It is one of the three domestic development units for the domestically-owned ethylene cracking furnace-CBL cracking furnace and has been completed in recent years. Development and design and industrial application of CBL-II to CBL-VI and SL-I and SL-II ethylene cracking furnaces. As a joint development and design institute, the institute is mainly engaged in the research and development of quenching boilers and combustion systems for ethylene cracking furnaces. It owns and has mastered advanced fluid mechanics software-CFX and multiphysics calculation software-ANSYS, and has advanced quenching boilers. The test device and the combustion test device have a complete set of experimental test instruments.
After actively tracking foreign advanced technologies, the institute has developed many independent quenching boiler technologies and burner technologies with independent intellectual property rights after more than years of independent innovation. More than 10 technologies have been awarded national and provincial-level technology. Progress award and national patent authorization, more than 400 sets of quenching boilers and more than 2,000 burners for ethylene cracker have been successfully applied to major petrochemical enterprises in China.
Tianhua Chemical Machinery and Automation Research and Design Institute and Sinopec Tianjin Petrochemical Branch Co., Ltd. jointly undertaken the Sinopec scientific and technological research project, the industrial application test of large-scale cracking furnace burners, and passed the technical appraisal organized by Sinopec in Beijing last week. Experts commented that the overall technology of this achievement has reached the international advanced level, and the benefits of energy saving and environmental protection are significant, filling the gap in the bottom combustion system for domestic large-scale ethylene cracking furnaces.
