WNS type oil and gas boiler is steam boiler developed in cooperation with German technology. Its technical indexes all reach the world's advanced level.The type boiler really did clean combustion, emissions, no pollution, convenient operation, the output is enough, the ontology of pot shell all wet back downstream three return fireworks tube structure, indoor micro positive pressure combustion flame in the combustion, burning full, furnace heat load is low, the SOX. The harmful substances less NOX emissions, corrugated furnace and threaded pipe structure, which can not only improve the strength and strengthening heat transfer effect, and meet the requirements of parts heat expansion at the same time.The front and rear smoke boxes are connected by hinges, which can be opened easily and repaired quickly.

steam boiler features
Reasonable design: horizontal internal combustion three - return full wet - back design corrugated furnace.It has good thermal retractility.The overall design of water and fire, sufficient heating area and reasonable structure layout, is the guarantee of high efficiency of boiler.
High efficiency and energy saving: the thermal efficiency of steam and hot water boilers is between 90%-95%.Large space combustion chamber with reasonable structure arrangement can transfer more heat into water, greatly improving the heat exchange capacity of fuel - steam and fuel - hot water
Meet the requirements of environmental protection: large combustion chamber, full use of radiation heating, coupled with high quality and reliable imported burner, so that the fuel can be completely burned, greatly reducing the emission of harmful components in the flue gas.By the statutory department test, the company's fuel (gas) steam, hot water boiler meets the environmental requirements, is the ideal environmental protection products.
Excellent configuration: supporting world famous burner, advanced control system (main components are imported parts), valves, pumps are all made of quality products, and excellent boiler accessories provide strong guarantee for the safe and stable operation of the boiler.
Fully automatic operation: the boiler can run according to the set program as long as the user only needs to start the button.Load section, water supply, etc. are fully automatic operation, without special care
Convenient maintenance: the boiler is equipped with movable smoke box door before and after, and there are fire viewing holes and inspection holes in the rear, which can be entered into the furnace for inspection and cleaning.Manholes are opened on the furnace body, and the structural design fully considers the convenience of maintenance in the future.
