2) gas steam boiler Adopts horizontal type three pass structure, absorbs the thermal expansion effectively. Uses large diameter corrugated furnace, large combustion space, high combustion efficiency.

3) The spirally corrugated tube strengthen the disturbance of flue gas, high heat transfer efficiency.

4) The boiler shell use aluminium silicate board for heat preservation, low heat loss.

5) Equipped with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, the thermal efficiency could be increased to as high as 98%.

2. 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.

3) Equipped with explosion proof equipment, discharge high energy when deflagration happened in furnace, to ensure the boiler operate safety and efficiently.

3. Full Automatic Control

this oil fired steam boiler Adopts PLC full automatic intelligent control cabinet and 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.

4. Low Cost

1) Adopts proprietary technology of Sitong Boiler, the boiler is 100% butt welding, high quality, and long working life, low maintenance fee.

2) The oil fired steam boiler has high combustion efficiency，energy saving, and low cost on fuel.

5. Save Space

Adopts fast assemble structure, compact structure, convenient for transportation, small occupation.

6. Convenient Maintenance

1) There are manhole, head hole, and special hand hole on the boiler. The front and back smoke chambers are equipped with movable doors, convenient for boiler internal installation, inspection and clean.

2) The explosion proof door has the fire sight glass and inspection gallery, convenient for furnace checking and maintaining.

Application

As the WNS series oil gas fired packaged boiler has the characteristics of compact structure, safe operation, convenient installation, low pollution and low noise, it is widely used for industry production and processing, such as textile mill, medicine industry, food & beverage industry, chemical industry, garment industry, food processing industry, and wood processing industry, moreover, it could be used for central heating in enterprise, hotel, hospital, civil architecture, etc

FAQ

1. What are the available fuel for the oil gas fired boiler?

Oil gas fired boiler could burn both liquid fuel and gaseous fuel. The liquid fuel could be heavy oil, light oil, diesel, furnace oil, bunker oil, LPG (liquefied petroleum gas), etc. The gaseous fuel could be natural gas, city gas, bio-gas, etc.

2. Whether the boiler can burn dual fuel or multi-fuel?

Small steam boiler have oil burner, gas burner, and oil&gas dual fuel burner, we can offer the specific burner based on customers’ requirement.

3. What is the texture of spirally corrugated tube?

The texture of spirally corrugated tube is 20#.

4. The brand of burner?

The brands of burner are Italy Baltur, Rellio, Elco, etc.

5. What is the thickness of combustion chamber?

the thickness of corrugated furnace is different based on working pressure and furnace diameter, generally, the thickness is between 10~18mm, large combustion space, and combustion sufficient.

6. What is the advantages of fire tube boiler?

This fire tube boiler has compact structure and convenient operation, strong load adaptability, lower water quality requirement, and the failure rate of it is lower than 0.1!

7. Details of electric control cabinet.

Electric control cabinet adopts PLC touch screen, display in English. It shows working condition details of boiler, such as water temperature, water pressure, exhaust gas temperature, and over-pressure alarm, etc. In addition, the cabinet is used for set up the parameter, record and analyze the operation data, etc.

8. What is the inlet pressure of gas burner?

The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 18~20KPa.
