WNS series horizontal internal combustion boiler is classic 3-pass wetback oil/gas fired boiler. After fuel is atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, called 1st pass; the high temperature flue gasses are collected in reversal chamber and then enter 2nd pass, which is grooved tube bundle area through heat convection, air temperature gradually falls and flows to front smoke box and enter 3rd pass, which is done in the smooth tube bundle area, and then through back smoke box lead to chimney and exhausted to the atmosphere.
WNS series gas-fired (oil-fired) hot water boiler adopts full-wave furnace, which has good thermal expansion; full-edge butt welding technology reduces the temperature difference stress of the furnace. The connection between the pipe and the tube plate is in the form of first expansion and post-welding, which eliminates the corrosion problem and prolongs the service life of the boiler. The heat exchange of the threaded pipe increases the heat transfer coefficient of the boiler. The product has beautiful appearance, high thermal efficiency, low fuel consumption, stable output, short installation period, convenient maintenance and high automation.
1. Horizontal internal combustion three-return pyrotechnic tube shell full wet back boiler, stable operation.
2. The flexible corrugated, two-return screw-type pipe has a large heating area, good heat transfer effect, sufficient output and low exhaust gas temperature.
3. The boiler is burned with imported famous brand burners. The boiler is burnt for micro-positive pressure combustion. The power conditions are reasonable, smooth, full of combustion, smokeless dust and noise, and the environmental protection effect is good.
4. Fully automatic operation, high automation program and simple operation management.
5. Pressure, temperature, water shortage and burners use multiple interlocking protection to ensure safe and reliable operation of the boiler.
6. Applicable to a wide range of fuels, such as light oil, heavy oil, residual oil, natural gas, city gas, petroleum liquefied gas.
7. Polished stainless steel outsourcing, beautiful and generous.
8. There are two categories of atmospheric pressure and pressure, which users can use first according to their needs.
