The outer surface of the WNS hot water boiler body is covered with aluminum silicate felt with good thermal insulation performance. The outer frame is made of cold-drawn plates processed by a CNC folding machine, and is formed into a “concave”-shaped skeleton with strong pressure resistance, which is connected and welded with the front and rear panels. Its packaging panel is a rectangular inlaid snap-in assembly, with recessed self-tapping holes at all four corners, and is sealed with a 304 decorative cover for easy maintenance. The overall appearance of the 1400KW WNS condensing boiler is beautiful and novel, the heat dissipation loss is small, and the thermal efficiency of the boiler is improved. The condensing boiler uses the condenser and economizer to absorb the sensible heat in the high temperature flue gas discharged by the boiler and the latent heat released by the condensation of water vapor, so as to achieve the purpose of improving the thermal efficiency of the boiler.
The low nitrogen condensing hot water boiler tube sheet and the cylinder are connected by a pull-edge structure. The main welding seam of the main body is a butt structure, and all the welding seams are completed by submerged arc automatic welding. This series of boiler products has abundant heating area, large furnace structure, slightly positive pressure combustion, low combustion heat load, and low emission of harmful substances. The boiler combustion chamber design is reasonable, fully adaptable to city gas, natural gas, light diesel oil, heavy oil and other fuels.
The technical indicators such as flue gas blackness, soot blackness, concentration and noise of this type of gas boiler are better than the regional standards of the first class. The radiant heating surface of the hot water boiler is a full corrugated furnace, and the convection heating surface adopts a threaded smoke pipe, which has a large heating surface. The thermal efficiency of the boiler is high, which is higher than the relevant regulations. The main longitudinal and circumferential welds of the condensing hot water boiler are heat treated according to JB/T1613 after welding to eliminate stress and ensure welding quality. 1400KW WNS condensing boiler automatic welding equipment to ensure the qualified rate of flaw detection. The boiler is outsourced with colored steel plates, with hinged smoke boxes at the front and rear, and the surface is painted with high temperature, which is novel and beautiful.
The heat exchange area and flue pipe size of the condensing hot water boiler have been reasonably designed and calculated. Because the boiler has internal thermal stress, the design is more flexible. The three-return flue tube design achieves low pollutant emissions and high combustion efficiency. This series of hot water boilers have high thermal efficiency, and the water-cooled finned tube rear wall (made of finned tubes) increases the utilization rate of thermal energy and reduces the radiation heat dissipation inside the boiler. In the back of the fire tube of the boiler, there is no need for work such as bricklaying (or fireproof cement).
The low nitrogen condensing boiler adopts a large furnace design, which increases the combustion space and reduces the flame temperature. The low-nitrogen burner is matched with it, which not only increases the thermal efficiency of the boiler, but also achieves low nitrogen emissions. The 1400KW WNS condensing boiler is designed with a jet return water outlet, and the external return water cold water can be quickly mixed with the hot water in the boiler. This ensures that there is no danger of condensation in the flue pipes at the boiler return. For steam boilers, there are many return holes on the return pipe. The return water can be quickly mixed with the hot water in the boiler through these small holes, avoiding the thermal shock inside the boiler and prolonging the service life of the boiler. WNS hot water boiler can be flexibly used with various other equipment. Compact shape design, compact structure, flexible installation position.
