This oil &gas steam boiler is three return fire tube steam boiler. The burning control, water feed, programs run, etc, is full automatic.It equipped with a bias furnace tube structure, and high temperature gas into the atmosphere through five-return smoke tube, smoke chamber. It equipped with good performance burner and advanced techniques. This fantasy boiler is safe and reliable, and also has the advantage of compact structure, simple operation, easy installation, high efficiency, less pollution and noise, etc

Boiler characteristics
1. High Efficiency
1) Equipped with specific burner, high automation and combustion efficiency, low NOx emission.
2) Increases the layout of horizontal fins and vertical fins based on the boiler capacity, combustion gas flows among the water tube bundle at a high speed, excellent heat convection and fast heat transfer efficiency.
3) By equipping with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, the thermal efficiency increase to as high as 96%.
2. Full Automatic Control
1) The burner is full automatic, stable operation.
2) Full automatic interlock protection program, has the protection function of water shortage, over pressure, over temperature, gas leakage, flame out, electric leakage, and phrase-lacking or overloading of motor, etc.
3. High Safety Performance
1) Complete gas manifolds and protection system, including filter, pressure regulating valve, and solenoid valve, etc., to ensure the safety performance of fuel.
2) Reliable boiler auxiliaries and multiple safety protection devices, such as pressure controller, pressure transmitter, water level alarm, safety valve, etc.
4. High Quality
1) All the materials has quality certificate, uses full automatic CO2 welding, NDT test and hydraulic pressure will be done for all boilers to ensure the quality.
2) The preheater uses seamless steel pipes, which are treated by sand blasting and hot-dip galvanizing, lengthen the working life.
5. Centralized Control
Several boilers could be used in parallel, and controlled centrally. Moreover, the centralized controller could record the downtime, location, evaporation capacity, fuel consumption, water volume, steam pressure, water tube temperature, exhaust smoke temperature, etc.
