Through the reasonable design of heating surface, the temperature of exhaust gas can be greatly reduced. Industrial oil fired boiler to ensure that the water vapor in the flue gas to meet the design requirements of low nitrogen rate. At the same time, the sensible heat in the flue gas and the latent heat of vaporization released in the process of water steam condensation are absorbed and utilized to greatly improve the thermal efficiency of the boiler. This series of steam boiler three return design is to improve the heating area of the boiler, further strengthen the thermal efficiency of the boiler.
Oil fired steam boiler with back structure, the use of (FGR) flue gas external circulation, full premixed surface combustion and other technical advantages, NOx emissions meet the national standard, the boiler is equipped with blue flame burner, NOx emissions may also meet the corresponding international emission standards. The energy saving effect is very significant, and the thermal efficiency is more than 100% based on the low heating value of the fuel. The structure of the boiler adopts a highly integrated technology, the body heating surface and low temperature expansion heating surface (energy saver and condenser) highly integrated, so that the type of boiler structure compact, small occupation area, save the boiler room construction land and capital construction costs, while simplifying the on-site installation workload. More environmentally friendly. The harmful gas of flue gas is effectively controlled, and flows into the neutralization tank with the condensate, which can effectively reduce the emission and improve the emission index.
WNS series steam boiler has the characteristics of safe operation, easy operation, quick installation, less pollution, low noise and high efficiency. The boiler is suitable for hot spring bath, sauna steam room, printing and dyeing textile, workshop office school, medical and pharmaceutical, hotel and catering, food processing, chemical plants, socks factory heat styling, clothing processing, industrial steam washing, heating and drying farms and other industries. The industrial oil fired boiler adopts the butt-welding seam of the whole cutting edge, which has high reliability and low maintenance cost. In addition, the use of advanced wavy furnace structure, not only to enhance the heat transfer area, but also to meet the furnace free expansion after heating.
This series of boiler products adopts the wave furnace, which not only strengthens the flue gas disturbance, but also increases the radiation heat transfer area; It not only increases the stiffness of the furnace, but also effectively weakens the thermal stress of the furnace. It not only enhances the heat transfer effect, but also promotes the combustion of fuel in the furnace. The whole heating surface is symmetrical arrangement, the structure strength is firm, the water circulation system is reasonable. The water capacity of the upper cylinder is large, the steam space is large, the steam quality is good, and the water level fluctuates little during the operation period. Large distance between the two cylinders and large pipe diameter ensure good natural circulation. The unique furnace setting and flue gas scour mode to the hot surface make the heat dissipation loss of the boiler small.
Industrial oil fired boiler with 100% corrugated furnace has good thermal scalability. The whole design of water and fire, sufficient heating area and reasonable structure arrangement are the guarantee of boiler operation. This series steam boiler combustion chamber space is large, make full use of radiation heat transfer, coupled with reliable imported burner, so that the fuel can be completely burned, greatly reduce the emission of harmful components in the flue gas.
