CWNS type fuel (gas) hot water boiler

The CWNS series hot water boiler is a three pass fully wet back large combustion chamber shell boiler. Its main structure consists of a shell, furnace chamber, smoke transfer chamber, convection tube bundle, etc. The convection tube adopts threaded tube to enhance heat transfer. Large furnace chamber, high radiation surface, three pass design, sufficient combustion air, high utilization rate of heating surface. The application of turbulence plate technology in smoke pipes not only expands the heat transfer surface, but also effectively reduces thermal resistance and improves heat transfer efficiency through its self-cleaning function for smoke and dust. Using high thermal resistance insulation materials to minimize boiler heat loss; ◆ Thermal efficiency above 90%. Intelligent and fully automatic control, with temperature regulation and over temperature standby. In winter, it has functions such as low temperature and anti freezing at night, and can automatically adjust the heating temperature according to changes in outdoor temperature to maximize energy savings; ◆ Imported burner, pressure atomization, complete combustion, low noise. The reduction of combustion intensity leads to a decrease in smoke and dust emissions, and the emission of harmful gases such as NOX is minimized, meeting strict environmental requirements; Adopting a pressure bearing connection structure, it is safe, reliable, and has a long service life. It has multiple interlocking protection functions such as overheating, water cut-off, overload, ignition failure, abnormal shutdown, gas boiler pressure, and gas leakage self check. The expansion tank is directly connected to the atmosphere and operates under normal pressure without any safety hazards;
