Hotel school hospital heating system high pressure condensing double pass fire hot water tube boiler

Gas Water Boiler Introduction:

WNS series condensing pressure exhaust heat recycle gas fired hot water boiler adopts shell type corrugated furnace structure, two passes design with wet back smoke-transfer chamber, Spirally corrugated tube technology , air pre-heater at the front of boiler.The energy-saving condenser at the top achieves third pass smoke flow,so that fresh air can fully absorb the waste heat from the flue gas to lower the waste smoke temperature to 60 degree centigrade. It is split-type frequency conversion burner, and mature technology, safe and stable operation, high heat efficiency,and is packaged in stainless steel, which looks elegant.
