The WNS series light diesel boiler built by ZOZEN Boiler adopt a packaged structure, which is composed of the boiler body, burner, economizer, condenser, water and steam system and control system. It has the advantages of less occupied area, convenient installation and maintenance. This time, the boiler solution customized by ZOZEN for Inversiones Goa 7 C.A. not only has sufficient output, but also has the advantages of convenient operation, environmental protection and high efficiency while meeting customers needs, and all technical indicators have reached the advanced level at home and abroad. According to the video data sent back from the customer site, ZOZEN WNS oil-fired boiler is operating very well.
The steam boilers in the hospital are mainly used for sterilization and have certain requirements for the quality and quantity of steam. This time, Shandong Jining Psychosis Prevention and Treatment Hospital purchased two sets of WNS series gas-fired steam boiler from ZOZEN Boiler. This series of boiler has a wide fuel adaptability including natural gas, coal gas, biogas and so on. It also adopts the large-diameter corrugated furnace to ensure the sufficient combustion of fuel and the high thermal efficiency of over 98%. Equipped with the imported low-nitrogen burner, it can easily realize the ultra low NOx emission.
Recently, ZOZEN took a field trip at the project location of the WNS boiler. The ZOZEN WNS series gas-fired steam boilers are horizontal wetback fire-tube boilers which have reasonable internal structure. An advanced low NOx burner is equipped with the boiler to reduce the NOx emission to less than 30mg/Nm3. At the same time, the burner can realize automatic air adjustment, which can ensure the sufficient fuel combustion.
Bolivia is the highest average altitude country in the world, local Bolivian companies have higher requirements for boilers than general boilers. As the altitude increases, the atmospheric pressure and the air density decrease accordingly, which adversely affects boiler combustion.
In view of this situation, ZOZEN technical team makes adjustments from the combustion system and exhaust system of boiler, fully considering the influence of low air pressure on boiler body design and combustion. By appropriately increasing the volume of the furnace to extend the residence time of the fuel in the furnace, and the problems of slow fuel burning speed and long burning time are solved.
