Overview of the development of heat treatment ener

  • Detail

Summary: This paper briefly discusses the development status of foreign heat treatment energy technology and the development status of domestic heat treatment energy technology, and focuses on the status and development trend of foreign natural gas energy technology and the status and application prospects of natural gas energy technology in China; At the same time, it discusses the prediction of the development and application of natural gas energy technology in China's heat treatment industry, and the key technologies and key equipment for the research and development of natural gas application in heat treatment industry, and puts forward the effective measurement range of initial experimental force for the adjustment of energy structure in China's heat treatment industry: 2% - 100% FS; Step assumption. Key words: natural gas; Energy technology; Energy structure; Introduction natural gas energy industry is an ancient and young industry. In ancient China, as early as the spring and Autumn period and the Warring States period more than 2000 years ago, there were records of Sichuan working people using natural gas to boil salt production. In modern times, with the progress of natural gas energy technology and the continuous expansion of natural gas application fields, the natural gas energy industry has developed rapidly, especially in the 1970s, the western industrial countries formed a system of high-performance modified plastics and plastic wood products for multiple utilization fields. The oil crisis and the shrinking of oil resources in recent years (Western countries estimate that with the current oil consumption, the world's oil reserves can only be used for 30 years), The upsurge of developing natural gas energy technology around the world continues to grow. According to the statistics of the world bank, from 1994 to 1998, the world's investment in natural gas development increased at a rate of 15.8%, and the funds injected into this field, including bank loans, reached 82.5 billion US dollars [1]. As an industrial fuel, natural gas is mainly used in electric power, metallurgy, machinery, cement, glass, ceramics, food and many other industries. Natural gas, liquefied natural gas and compressed natural gas can also replace gasoline. It is a high-quality and clean engine fuel, which can reduce environmental pollution. In the aviation industry, liquefied natural gas can compete with aviation kerosene and become the main fuel for supersonic aircraft

as a chemical raw material, natural gas can separate methane, ethane, propane, butane and more important hydrocarbons, then produce synthetic ammonia, urea, methanol, acetylene, carbon black, ethylene, propylene and butene, and then produce thousands of chemical products. For example, polyethylene, polypropylene, methanol protein, methyl tert-1, China has been looking for Subgrade ethers that return and lead the world's modernization, acetate fiber, methane chlorination products when the components are fully cured, synthetic rubber, synthetic fiber, synthetic plastic, etc. At present, 1/3 of natural gas is used as chemical raw material and 2/3 as fuel. 2 overview of domestic and foreign heat treatment energy technology (Table 1) table 1 overview of domestic and foreign heat treatment energy technology national or regional heat treatment energy consumption kw × H/t heat treatment efficiency% heat treatment energy structure heat treatment energy technology development measures Europe 300 ~ 450 40 ~ 50 coal, oil, natural gas, electricity and natural gas account for 20 ~ 30%, tap the potential of equipment, realize professional production and the best management of enterprises, develop high-temperature air combustion technology, regenerative burner technology, induction heating technology, etc. The United States 350 ~ 450 43 ~ 48 coal, oil, natural gas, electricity and natural gas account for 25.5% of the diversity of furnace heat sources, burner improvement, oxygen enriched combustion technology (1997), improvement of heat source materials, U-shaped and ceramic radiant tube technology, improvement of heat source shape and convection, improvement of thermal insulation materials, development of natural gas/electric heating system, reduction of NOx and SOX emissions and computer control technology (1999) Japan 32349.8 coal, oil, natural gas 36.1% of the total output value of burners for heavy oil fired furnaces, popularize and promote industrial furnaces with low fuel consumption, rationally use energy law (late 1970s), action plan to prevent global warming (1990), development of high-performance industrial furnaces, high-temperature air combustion technology (1992-1999), government financial support for China's 800 ~ 29 coal and electricity, with electricity accounting for more than 90%. Energy conservation law of the people's Republic of China (1998), The development of various energy sources (natural gas, nuclear energy, water power, wind power, etc.) began to research and develop high-temperature air combustion technology, high-performance combustion technology and devices, waste heat utilization and environmental protection technology, etc. 3.
