Structure of Automatic Condensing Oil-Fired Steam Boiler
Oil-fired steam boilers refer to industrial boilers that heat water to certain parameters and produce high-temperature steam. The water is heated in the drum to become steam, and the fire emits heat in the furnace, which is the principle of the steam boiler. The design, processing, manufacture, installation and use of automatic oil fired boiler must be supervised by the technical supervision department. The user can only use the steam boiler if he has obtained the boiler use certificate.
The oil-fired steam boiler can realize full condensation of flue gas and efficiently recover the latent heat of vaporization of flue gas H2O. This series of boiler products use energy saving and environmental protection. According to the traditional calculation method of low calorific value of fuel, the thermal efficiency can be greater than 100%. The main pollutants NOx, SO2, etc. in the flue gas of oil-fired boilers can be dissolved in condensed water, reducing pollutant emissions, environmental protection and energy saving.
The automatic oil fired boiler has a built-in two-stage series high-density staggered fin tube economizer. The boiler uses high-efficiency absorption of flue gas waste heat, realizes full condensation of flue gas, and recovers latent heat of gasification. WNS series steam boiler condenser and its flue gas flow flue are all made of acid corrosion resistant material ND steel (09CrCuSb) to prevent low temperature corrosion of flue gas, with a service life of ≥20 years.
The exhaust gas temperature of condensing oil-fired boilers can be reduced to below 70℃, which is far lower than the national requirements. The boiler thermal efficiency is calculated based on the low calorific value of traditional fuel, which can exceed 100%. This series of boilers reduce the heat load of the re-combustion chamber and reduce the thermal stress of the tube sheet of the re-combustion chamber. The boiler adopts an eccentric arrangement on the low side of the advanced burner, which meets the requirements of the two-pass heat transfer of the furnace body and improves the safety of the water circulation in the furnace.
All pressure components of the automatic oil fired boiler are symmetrical with the center of the drum, and the boiler adopts a full wet-back structure. With the structure of extremely large inner cylinder and eccentric fire box, it is beneficial to provide sufficient radiant heating surface. The oil-fired boiler adopts effective digital control technology. The combustion process can be monitored remotely during use, and the entire equipment is highly automated and well preserved. Equipped with high-quality imported low-NOX burner, the combustion is sufficient, and it is an environmentally friendly product.
