Detailed Product Description

The steam boiler is used of vertical furnace without bile tubes,four return structure.Effectively increaseing heat transfer to the gas water heaters,improving the thermal efficiency and good energy saving effect.Without pipe design,so that the products will not be scaled  and burned,heat evenly pass on the wall and heat transfer fin,avoiding stress,extending the service life. Compared with similar products. The combustor room is large and the furnace biliary export low-temperature,the main thread pipe is convection heating suface,the upper chamber can install the heat exchanger recovery to maximize saving energy.
