WNS type fuel (gas) steam / hot water boiler

Product application
Steam boiler: rated evaporation: 1-20t/h, rated working pressure: 0.7-1.6MPa
Zhongyue WNS series automatic fuel (gas) steam and hot water boiler is a horizontal three-return fire tube boiler. Its main structure consists of a shell, a furnace, a steering chamber, and a pipe. The boiler is suitable for light oil, heavy oil, natural gas, liquefied gas, city gas and other fuels.
The structure of the wet back and the corrugated furnace is adopted, and the heated surface is symmetrically arranged, so that the force and expansion of the boiler are more reasonable. Reasonable heating surface arrangement ensures good water circulation and heat exchange, so that the heat transfer effect is optimal, and the boiler thermal efficiency is improved.
The wetted back structure of the full butt weld avoids the damage of the rear wall to high temperature flue gas and ensures the reliable operation of the boiler.
The combustion chamber adopts a corrugated furnace, which effectively reduces the thermal stress of the boiler and improves the safety and service life of the boiler.
The use of international famous brand burners and advanced automatic control system makes the boiler combustion more stable, the operation is more convenient, the operation is safer and more reliable; the boiler installation time is short, and the instrument valve, water source, power supply, fuel pipeline and discharge pipeline are connected on the construction site. , you can put it into operation.
