Its technical advantages are: Environmentally friendly (flue gas emissions meet standard), energy-saving (efficiency increased by about 8%), and operating costs are very low. The combustion system saves more than 30% of electricity compared to chain furnaces. ； It saves more than 50% of electricity than fluidized bed or pulverized coal boilers. Therefore, it can fully replace various existing coal-fired boilers (including large pulverized coal boilers in power stations) and oil and gas boilers at home and abroad. Application demonstration examples and benefits 1. The 20T/h chain boiler uses coal molecular gasification and combustion, and the emissions meet the standards (the gas furnace lacks oxygen and solidifies sulfur ； α is close to 1 for combustion, pollution control costs are greatly reduced by 80%), and the combustion system saves more than 30% of electricity (α is reduced from 1.5 to 1.05 ； Gas combustion wind pressure drops by 50%) ； Coal saving is 10% (significant reduction in Q2, 3, and 4), and the transformation cost is recovered in 18 months. 2. The 35T/h fluidized bed boiler uses coal molecular gasification and combustion, and the emissions meet the standards (the gas furnace lacks oxygen to fix sulfur ； α is close to 1 for combustion, pollution control costs are greatly reduced by 85%), and the combustion system saves more than 60% of electricity (α is reduced from 1.2 to 1.05 ； Gas combustion wind pressure drops by 75%) ； Coal saving is 8% (Q2, 3, and 4 are significantly reduced). The renovation fee will be recovered within 16 months. 3. The 935 T/h pulverized coal boiler uses coal molecular gasification and combustion, and the emissions meet the standards (the gas furnace lacks oxygen to fix sulfur) ； α is close to 1 for combustion, pollution control costs are greatly reduced by 89%), and the combustion system saves more than 50% of electricity (α is reduced from 1.2 to 1.05 ； Combustion wind pressure drops by 70% ； Pulverizing power consumption is reduced by 60%) and smoke exhaust loss is reduced by 10%. Achieving prevention and control of the generation of harmful gases (SOx, NOx, etc.) from the source and element level has completely changed the passive situation in which desulfurization, denitrification and dust removal in power generation boilers have to increase energy consumption. The cost of coal-fired power generation is greatly reduced, and the economic and environmental benefits are huge.
