Heavy oil burner for low nitrogen gas hot water boiler
WNS low-nitrogen condensing (built-in) hot water boiler adopts mature three-pass full wet back structure, large open front smoke box design, and easy maintenance. It adopts low-nitrogen combustion large furnace full mixed combustion and equipped with high-efficiency heat transfer threaded smoke tube technology , Instilled flue gas external circulation (FGR) or fully premixed surface combustion technology principle, after testing, fully meets the 30mg low-nitrogen NOx combustion emission standard, and is fully suitable for the 30mg low-nitrogen emission city heating demand. The WNS low-nitrogen condensing hot water boiler adopts a large furnace full-wave furnace design, matching a reasonable low-nitrogen burner flame, fully reducing the combustion temperature in the high-temperature zone of the furnace flame, effectively controlling the increase of NOx concentration, and thoroughly meeting the low nitrogen emission requirements. Using threaded heat transfer calculation, spiral disturbance design principle, through three-dimensional animation simulation, design high-efficiency heat transfer resistance and small threaded smoke pipe, and use high-quality seamless steel pipe, so that it has good heat transfer, low friction resistance and prolonged service life. Equipped with invisible FGR flue gas external circulation configuration, which can meet the emission standards of 30mg low-nitrogen burners, equipped with Siemens solenoid valve, according to the burner's own combustion conditions to control the flue gas flow recirculation rate, to achieve the ideal low nitrogen emission below 30mg. WNS low-nitrogen condensing hot water boiler is equipped with a built-in condenser at the rear. All parts are laser-cut and cold-worked. The sealing plate is made of ND steel, and low-temperature corrosion-resistant spiral fin tubes are used to increase the heat transfer area in a limited space. , Fully absorb the tail flue gas, reduce the exhaust gas temperature, improve the thermal efficiency of the boiler, and its structure is built-in, it does not occupy the space of the boiler room, and it has a wide range of applications. The design concept of the front smoke box adopts a double-layer double-set built-in labyrinth insulation layer and a two-layer structure with a heat-resistant layer, which has good thermal insulation performance. The smoke box panel and the smoke box cover are made of integral Q245R boiler steel plate, and the steel plate blanking adopts laser The numerical control cutting technology has small deformation, high assembly precision and good welding shape. It is mainly convenient to open and tightly sealed, which is convenient for users to inspect and maintain. The outer surface of the WNS low-nitrogen condensing hot water boiler body is made of aluminum silicate felt with good heat preservation performance, and the outer frame is made of high-quality cold-drawn plates by CNC folding machine, and becomes a \u0026ldquo;concave\u0026rdquo; Strong ability. The frame and the front and rear panels are connected and assembled. The packaging panel is rectangular inlaid and snap-in assembly. The four corners are equipped with trapped self-tapping holes, and are sealed with 304 decorative covers, which are convenient for maintenance. The overall appearance is beautiful and novel, and the heat dissipation loss Small, improve boiler thermal efficiency. ! If you are interested in heavy oil burners, please ask us for prices!
