Product Description
Introduction
Zhongding WNS series crude oil fired wet back boiler is jointly designed by Xi’an Jiao Tong University, it is a kind of safe and high efficiency heating equipment with full automatic control system. Zhongding Boiler adopts the national patent technology, optimizes the design of oil gas fired boiler, to achieve a more reasonable combustion chamber and heating area, the thermal efficiency increases more than 10% compare with the ordinary boiler. The boiler is equipped with explosion proof equipment at the back of boiler, prevent deflagration in furnace, discharge high energy, and automatic reset as well, to ensure the boiler operate safety and efficiently.
 
WNS series crude oil boiler is horizontal type fast assembly fire tube boiler with three pass structure, it has compact structure, small volume, strong load adaptability and low water quality requirement. This boiler adopts wet back structure, it can adapt to the high temperature, has a good sealing, increase the radiation heat transfer area and improve the heat transfer efficiency. 



Application

WNS series crude oil fired wet back steam boiler is widely used for industry production and processing, such as textile mill, medicine industry, food & beverage industry, chemical industry, garment industry, food processing industry, and wood processing industry, moreover, it could be used for central heating in enterprise, hotel, hospital, civil architecture, etc.
