Oxygen-enriched combustion has broad application prospects and the industry is developing rapidly

Oxygen-enriched combustion is an efficient and energy-saving combustion technology, which refers to the complete combustion of oxygen-containing gases with a higher oxygen content than the air, so that fuel molecules and oxygen are more closely combined, thereby generating more heat. Compared with ordinary air combustion, oxygen-rich combustion has the advantages of accelerating combustion, reducing the amount of smoke after combustion, outstanding environmental protection effect, and effectively extending the life of the furnace. It is suitable for ceramics, fiberglass, lime, cement, gypsum board, etc. Furnace enterprise.

In the early 1980s, oxygen-enriched combustion technology was first proposed. This technology was initially applied to pulverized coal boilers for the purpose of capturing and processing carbon dioxide. However, in actual use, there were problems such as high power consumption and high operating costs. Since 2005, this technology has been mainly used to study circulating fluidized bed boilers. In 2012, Spain’s CIUDEN Technology R&D Center built the world’s first 30.0MW (th) oxygen-enriched fluidized bed test device. In February of the same year, my country’s first 100,000 tons/year carbon dioxide capture oxygen-enriched combustion boiler system successfully completed the acceptance inspection.

According to the “2022 Global and China Oxy-Combustion Industry In-Depth Research Report released by the Industrial Research Center, oxy-combustion has a wide range of uses. , the building materials field is its main demand side. Using oxygen-rich combustion in the cement kiln for the clinker production line can achieve energy saving and emission reduction. Benefiting from the rapid economic development, the prosperity of my country’s building materials industry has improved. At present, the oxygen-enriched combustion technology of cement kilns has been mastered by many building materials companies in my country, and the industry development space is expected to expand.

In recent years, the problem of global warming has intensified, and reducing carbon emissions has become a research hotspot in various countries. Oxygen-enriched combustion, as a new type of high-efficiency and energy-saving combustion technology, has received widespread attention from countries around the world. After years of development, my country, the United States, Spain, Canada, Australia, Japan and other countries have developed independent research and development capabilities for oxygen-rich combustion technology and equipment. The world’s leading oxyfuel combustion companies include France’s Alstom, Japan’s Hitachi Metals Co., Ltd., and the United States’ Babcock Wilcox Co., Ltd., etc.

Our country began to study oxygen-enriched combustion technology in the 1990s. Although the industry started relatively late, it has developed rapidly. At present, many companies in my country have oxygen-enriched combustion technology and equipment, including Chongqing Furan Technology Co., Ltd., Yantai Jiuzhou Fuel and Gas Energy Saving Technology Co., Ltd., Dongfang Electric Group Dongfang Boiler Co., Ltd., and Sichuan Air Separation Equipment (Group) Co., Ltd. Responsible companies, etc.

Industry analysts said that oxygen-rich combustion, as a new energy-saving combustion technology, has broad application prospects in furnace-related industries. With the increasing market demand Strong, its market space will be further expanded. my country’s oxyfuel combustion industry started late, but it is developing rapidly. Driven by the technological innovation of local enterprises and related research institutions, the application scenarios of oxyfuel combustion continue to expand.
