[0002] Most existing oil-fired and gas-fired steam boilers use shell and water tube structures, which have the problem of low utilization efficiency. On the one hand, the combustion efficiency of oil and natural gas needs to be further improved, and on the other hand, the exhaust temperature of natural gas utilization equipment needs to be further reduced to improve the equipment conversion efficiency. At present, oil-fired and gas-fired steam boilers mostly use atmospheric or diffusion combustion devices, which have low combustion efficiency, high NOx emissions, and exhaust temperatures generally above 150-180°C. The heat of the flue gas after boiler combustion lacks deep utilization, resulting in a huge waste of clean energy such as oil and natural gas, and also aggravates environmental pollution to a certain extent. Steam boilers refer to boiler equipment that produces steam. They are special equipment. Their design, production, delivery, and installation must be subject to supervision by the national technical supervision department. Users need to obtain a boiler use certificate to operate the boiler. In order to improve the efficiency of steam boilers and better save energy, a condensing integrated steam boiler is needed.
