Sectional Axonometric Drawing

�Grasping the pulse of the times, in line with energy-saving and emission reduction

policy-oriented, ZBG launched out the WNS series oil and gas boiler. As the

subproject of high efficient and green boiler in the World Bank Group's GEF

Program, each technical index of WNS series oil and gas fired boiler has reached

the world advanced level. Through the layout of a reasonable furnace size, which

makes the combustion chamber evenly distributed in the temperature field, flame

stability, high combustion strength, and greatly improve the combustion efficiency,

can be widely used in production, power generation, heating, hot water supply

and other fields. WNS series boiler is fast-assembly installation boiler and it mainly

consists of boiler proper, interconnecting flue, burner, steam & water system,

meters, economizer and condenser (optional). Focusing on the development and

production of clean boilers, we have constantly promoted low-level environmental

protection level of oil and gas boiler to a new height in China for years. At

present, ZBG low nitrogen NOx emissions of WNS series oil and gas boiler is far

lower than 30mg/m3 requirement that the Beijing Municipal Government

announced the "Beijing Boiler Air Pollution Discharge Standard".

Capacity: 1 - 20 tons/0.7-14MW

Design thermal efficiency: �≥95%

Applicable fuel: Natural gas, light oil, heavy oil, gas, etc

Application: Central heating, public heating, steam for production

Product introductionProduct introduction

SINCE���1945SINCE���1945

The large combustion chamber ensures the fuel fully burned and the NOx

emission is less than 35mg/m3.

Full burning and low NOx emission1

a. Adopts advanced corrugated furnace to increase heat transfer area and

satisfy the free expansion of the furnace after being heated.b. The smoke tube adopts thread structure to improve heat transfer effectiveness.

High efficiency and energy saving2

a. Adopts wet-back structure with butt weld to improve the reliability and reduce

the maintenance cost.

b. Various protection functions ensure the boiler’s safe and reliable operation.
