Product Introduction>>

The WNS low nitrogen hot water boiler adopts a mature three pass full wet back structure, with a large opening front smoke box design, a low nitrogen burner combined with a large furnace and high-efficiency heat transfer threaded smoke pipes, and the principle of injecting flue gas external circulation (FGR) or fully premixed surface combustion technology. The boiler is matched with a reasonable low nitrogen burner flame, which fully reduces the combustion temperature in the high-temperature zone of the furnace flame and effectively controls the increase in NOx concentration. After testing, the boiler meets the ultra-low nitrogen emission standard of NOx ≤ 30mg.

The combustion chamber of WNS low nitrogen hot water boiler is composed of a large diameter full corrugated furnace chamber, with a large combustion space, sufficient fuel combustion, effective absorption of thermal expansion, and a large radiation heating area. The diameter of the pot shell is large, the water capacity is large, the adaptability to load changes is strong, and the output is stable. Using thread heat transfer calculation and spiral disturbance design principle, efficient heat transfer and low friction resistance threaded smoke pipes are designed through 3D animation simulation. High quality seamless steel pipes are used to achieve good heat transfer, low friction resistance, and extended service life.

The tail of the WNS low nitrogen hot water boiler is equipped with a built-in recovery heat source device. All components are laser cut and cold worked, and low-temperature corrosion-resistant ND steel spiral finned tubes are selected to increase the heat transfer area in a limited space, fully absorb the tail flue gas, reduce the exhaust gas temperature, and improve the thermal efficiency of the boiler. Its structure is built-in and does not occupy the space area of the boiler room, making it widely applicable.

The outer surface of the WNS low nitrogen hot water boiler body is covered with aluminum silicate felt with good insulation performance. The outer frame is made of high-quality cold drawn plate processed by CNC folding machine, and is formed into a "concave" shape with strong pressure resistance. The skeleton is connected and welded to the front and rear panels. The packaging panel is a rectangular embedded snap in assembly, with concave self tapping wire holes at all four corners, and sealed with 304 decorative cover for easy maintenance. The overall shape is beautiful and novel, with low heat dissipation loss and improved boiler thermal efficiency.
