Oil(gas) Fired Steam Boiler with Energy Saver
Steam Capacity: 1-10t/h
Rated Working Pressure: 7bar, 10bar, 10bar, 12.5bar, 16bar, 20 bar
I. Structure of the boiler
1. WNS series full automatic boiler adopts heat components of the structure of horizontal three pass 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.
II. Technical characteristics
1. Possessing three national patent product;
2. Horizontal body three-pass design;
3. Furnace symmetrically located in the central low level;
4. Full wet-back structure;
5. Corrugated furnace and screw thread matching design;
6. Full butt-joint welding structure;
7. Front and back smoke boxes double seal structure;
8. Economizer(Energy saving device) is installed on the back smoke box; Compact in structure, small floor area;
9. Installing explosion-proof door at furnace outlet;
10. Automatic intelligent control system of PLC Touch Screen and PC digital.
