China Gas or Fuel Steam Boiler

Horizontal Gas (Fuel Oil) Fired Steam Boiler
I. Structure of the boiler
1. WNS series full automatic boiler adopts heat components of the structure of horizontal tri-backhauling wet back as threaded smoke tube. Adopting wetback down stream structure can avoid the problems that the smoke box of the dry back and central back flash system could be sealed and the temperature of the smoke box could be too high.
2. The furnace adopts the most advanced domestic structure-corrugated furnace, which can increase the heat transfer area and the stability of the furnace.
3. The smoke tube adopts high efficient heat transfer component_threaded smoke tube. It raises the heat transfer coefficient of the smoke tube. The volume of the boiler can be further decreased.
4. The entire boiler installed in the steel base. If the FD fan needs to be installed separately, then use the flexible joint at the interface of combustion chamber and the blower duct. Steel base using fixed angle expansion bolts.
5. Boiler using two-way full-opening and big-open furnace door design. The internal structure of the furnace is clear and repair to maintain. Observation window installed at both ends of the boiler, install hand-holes in order to check and clean the boiler. Install lifting rings at the top of the boiler shell installed front and rear hinges, gaskets and insulation.
