WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
1. WNS series oil fired boiler adopts the boiler structure of three passes fully wet back technology.
2. The design of furnace heat transfer and flue gas tube radiation heat transfer is reasonable, the boiler layout is reasonable, and the thermal efficiency is high.
3. The water capacity of the boiler is larger, and the whole radiation heat transfer and heat exchange technology is adopted, which is especially suitable for medium and large boilers.
4. The furnace adopts a unique combustion chamber layout, the whole combustion chamber is located in the center of the boiler water, making full use of radiation heat transfer to heat the boiler water, and the corrugated furnace is used as the combustion chamber so that the combustion is full, the heat exchange is more full, and the thermal efficiency of the boiler is higher.
5. The design of the furnace heating surface is simplified, with a larger heating area, smaller stress, more stability, and higher thermal efficiency.
