ZOZEN has always been committed to continuously improving the thermal efficiency of gas-fired boilers. WNS three-pass condensing gas-fired steam boiler is an environmentally friendly boiler product of ZOZEN. With advanced low NOx burner, the boiler thermal efficiency can be as high as 98% while achieving ultra-low emission of NOx≤30mg/Nm³. After the fuel is fully combusted in the large-diameter corrugated furnace, the high-temperature flue gas flows backwards to the second pass along the furnace through the reversal chamber , that is, the threaded smoke tube bundle area; After convective heat transfer, the boiler flue gas temperature gradually decreases and goes to front smoke box and turns to 3rd pass, that is, the smooth tube bundle area; Finally, the flue gas enters the economizer and condenser through the rear smoke box, and flows into the chimney and is exhausted into the atmosphere.
Veolia (Harbin) Thermal Power Co., Ltd. was established in 2003 and is a Sino-foreign joint venture controlled by Veolia Group.

Huludao Longgang District Heating Co., Ltd preferred ZOZEN boilers and ordered 2 sets of DHW series coal-fired boilers.
In the technological process of the battery production, many key links are inseparable from the heat source provided by the boiler. Whether the boiler operation is stable and efficient will directly affect the efficiency of the battery enterprise. Harbin Coslight Battery Co., Ltd. was established in 1997. It mainly produces lead-acid batteries and accessories. It is currently one of the largest manufacturers of valve-regulated sealed lead-acid batteries in China. With the continuous development of foreign markets, Coslight battery has been in short supply, and the production capacity has been further expanded and upgraded.
Steam boilers are essential in large hospitals, which are used to sterilize and disinfect medical equipment, hospital bed sheets, quilts, etc. and provide steam for washing machines and dryers in hospitals. Nanyang Second General Hospital is a three-level general hospital with more than 2,000 beds and over 80 clinical and medical technology departments. Therefore, the hospital has a large demand for steam. In response to the national green development concept, People's government of Henan province decided to repurchase a gas-fired steam boiler for daily sterilization and disinfection. Serving as a place of healing the wounded and rescuing the dying, the hospital has high requirements for the quality of steam and the stability of boiler operation. The project leader of Nanyang Second General Hospital was attracted by ZOZEN's perfect production line and strict quality supervision after inspecting many well-known boiler plants.
