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 one set of 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, and purchased one set of 10 tph WNS series gas fired steam boiler. This boiler has sufficient steam storage space and heating surface to ensure the quality and quantity of steam; and it adopts the most advanced ultra-low NOx burner at home and abroad, the NOx emission can be below 30mg/Nm³ in conjunction with a large-diameter furnace. At the same time, this series of steam boilers has the characteristics of fully automatic operation, and the combustion condition, water level, temperature and steam pressure can be automatically adjusted and protected to ensure safe and stable operation of the boiler for a long time.
After a period of operation, the WNS series gas-fired steam boilers provided by ZOZEN had met our expectations and needs from all aspects. Not only the energy saving and environmental protection effects are good, but the flue gas emissions are in full compliance with national regulations. What's more, the steam output is sufficient and the quality of steam is also very good.
