Oil gas boiler central heating system is to provide hot water or steam to the whole interior of a building from one heat source to multiple rooms. The whole system includes three parts: heat source, heat supply network, and heat user. The main heat source could be regional boiler plant. Generally, the industrial regional boiler plant uses steam boilers, for heating, drying, steaming, cleaning, cooling, melting during industrial production. While the civic regional boiler plant uses hot water boiler, to offer heating, ventilation, air-conditioning, and hot water supplying. Sitong Boiler produces large numbers of boilers that could used for central heating system.

CWNS series oil gas fired packaged boiler could be used for central heating. The boiler operate under atmospheric pressure,  it is very safe. This series packaged boiler is horizontal type fire tube boiler with three pass structure, it has compact structure, small volume, strong load adaptability and low water quality requirement. This boiler adopts wet wet back structure, it can adapt to the high temperature, has a good sealing, increase the radiation heat transfer area and improve the heat transfer efficiency.

Performance Advantages

1. High Efficiency

1) Equipped with high quality and reliable burner, high combustion efficiency, low harmful gas emission and noiseless operation.

2) 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

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 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.
