Description

technical field [0001] The invention relates to the technical field of secondary clean energy for raw coal liquefaction and clean thermal combustion for energy saving and emission reduction, in particular to a raw coal alcohol liquefaction process and thermal clean combustion method based on the effect of RSG engineering technology. Background technique [0002] China is rich in coal, poor in oil, and low in gas. The reserves of coal resources account for the second in the world, the total consumption accounts for 50% of the world, and the energy consumption structure accounts for 62%. The lack of clean energy has become a hidden danger to my country's energy security. The problems of the secondary energy "coal liquefied fuel" in my country's coal-water slurry project in the thermal combustion of small and medium-sized industrial boilers and kilns: ①The physical method has not solved the problem of coal slurry "sulfur, silicate" fuel pollution; ②Traditional combustion technol...

The problems of the secondary energy "coal liquefied fuel" in my country's coal-water slurry project in the thermal combustion of small and medium-sized industrial boilers and kilns: ①The physical method has not solved the problem of coal slurry "sulfur, silicate" fuel pollution; ②Traditional combustion technology only Refers to thermal combustion still requires a huge large flue gas treatment system to make up for the technical defects of coal-water slurry components; ③The environmental protection problem of the operation of special combustion and heating devices cannot meet the flue gas emission index "dust 10mmg / Nm" in key pollution control areas in my country 3 , SO 2 20mmg / Nm 3 , NO X 50mmg / Nm 3 "Basic requirements

[0003] GB16663-1996 "Alcohol-Based Liquid Fuels" designed the blending of industrial methanol materials to blend secondary clean energy. The results of the pilot test in the thermal industrial boilers and kilns and civil catering stoves provide a basis for China's substitution of diesel and gasoline and the elimination of raw coal, coal-water slurry, and biofuels. Highly polluting fuels have made positive contributions and have reached the level of engineering application technology; however, if the traditional alternative method of engineering application is still used, the common problem of low thermal energy efficiency and high operating costs of the system will continue, and the heating device will be affected. The carbon steel series metals cause corrosion, causing safety hazards for pressure-bearing equipment. The production cost of pure industrial-grade methanol chemical materials is relatively high, and the price fluctuates greatly due to the influence of the chemical market. Therefore, there are still great limitations in the application of thermal combustion. ; Although there is currently no lack of ways to add a variety of heating agents to solve the problem of low calorific value of alcohol-based fuels in our country: adding waste steam, diesel, coal, engine oil, tar, tire oil, and kitchen waste oil to alcohol-based fuels to increase the calorific value For the corrosion problem of flue gas condensate, nitric acid, ferrocene, potassium permanganate, etc. are added to alcohol-based fuels to increase the chemical reaction speed, but it will inevitably lead to SO 2 , NO X , dust emission exceeds the standard or loses the economy of clean fuel; therefore, they are unable to undertake the industrialization task of clean thermal combustion of raw coal liquefaction secondary clean energy in the industrial field
