Product Description

Three-Step Program Horizontal Fuel (Gas) Steam Boiler For School heating


Three-return structure

WNS series automatic fuel gas steam boilers are all shell-type three-return, full wet back structure.
Steam boiler features: All pressure components are symmetrical with the center of the drum. The boiler adopts a fully wet back structure with a large inner cylinder and an eccentric fire box structure, which is beneficial to provide sufficient radiation heating surface. The front tube plate of the back combustion chamber is connected with the furnace, and the back tube plate of the back combustion chamber is made of an ellipsoidal head and a tube sheet. The second return and the third return tanning chamber constitute the front smoke box. The structure of the front smoke box adopts a light structure refractory insulation material. The rear smoke box outlet is arranged in a direction along the longitudinal axis of the barrel. Mainly consider the principle of boiler overhaul and stability. The water mixing device installed in the backwater inlet of the boiler first flushes the pipe bundle of the pipe and then contacts the furnace to improve the water temperature of the returning water contacting the furnace. The phenomenon of partial cold boiling is avoided.


Wave furnace (according to the user's choice)

This series of boilers adopts the corrugated furnace, which not only enhances the disturbance of the flue gas, but also increases the radiation heat transfer area; it not only increases the stiffness of the furnace, but also effectively reduces the expansion stress of the furnace; It also promotes the combustion of fuel in the furnace.


Welding process of pipe and tube sheet

The advanced technology of first pre-expansion, full-welding, and then expansion is prevented from corrosion of the pipe gap and enhanced welding strength.



Symmetrical movement articulated front and rear smoke doors

Easy to open, easy to repair and clean.
