CWNS gas fired hot water boiler

  CWNS series of hot water boiler is three return trip back all wet big chamber boiler shells, the main structure be made of the shell pan, oven bile, changing breathing room, convection control components, convection breathing tube is threaded pipe used to enhance heat transfer.
Furnace big, high radiate,three return design, combustion air is full, high-efficiency heating surface. Application breathing tube additional spoiler film technology, not only expansion of heat, the dust and its "self-cleaning" feature can reduce thermal resistance, improve heat transfer effectiveness. Using high thermal resistance of insulation materials, boilers, heat losses to the minimum.
More than 90% thermal efficiency. Intelligent, automatic control, with automatic temperature regulation, over-temperature standby. Freezing cold winter night, and other functions, and to achieve the outdoor temperature changes automatically adjust the temperature heating function to maximize energy conservation.
Burners are used  by importing, pressure spray, burning completely, low noise. thus Combustion intensity will be reduced dust emissions reduction of harmful gases such as NOx emissions reduced to the minimum, to meet stringent environmental requirements.
Confined by connecting structure, safe, reliable, long service life. Super temperature,cut water, overload, ignition failure, abnormal flameout, gas boiler pressure, all can do self-test, multiple chain protection. Expansion of water  testing through the atmosphere, atmospheric pressure operation, there are no all potential safety problems.
