SZS Double Drums Horizontal Waste Oil Natural Gas Fired Steam Boiler for paper plant
SZS fuel gas boiler is a double-drum vertical chamber-fired boiler, composed of upper and lower drums, membrane water walls, burners, superheaters, convection tube bundles, economizers, and decontamination devices. Both the water wall of the furnace and the convection flue adopt a membrane wall structure, which reduces the use of refractory bricks. In addition, the boiler has the advantages of energy saving, high efficiency, environmental protection, short installation cycle, fully automatic operation, simple operation, perfect protection function, etc., which can not only meet the needs of industrial heating, but also meet the heating needs of small power stations. A very popular boiler on the market.

Technical Advantages
1. “D” shaped layout
Adopts double drums and “D” type structure, large combustion chamber, good flame fullness degree, sufficient combustion. The boiler has a sufficient output, and excellent overload capacity. Compact structure, covers a small area.
2. Membrane Wall Structure
The furnace adopts membrane cooling wall, and equipped with inner board with whole sealing welding structure, low heat loss, high thermal efficiency.
3. Good Thermal Insulation Property
The boiler shell uses aluminium silicate board for heat preservation, high thermal shielding efficiency, low heat loss, increase the boiler thermal efficiency.
4. Automatic Control
1) 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.
2) Adopts international brand burner, operate automatically, high combustion efficiency, low harmful gas emission and noiseless operation.
5. Safe Operation
1) Equipped with two explosion door at the furnace roof, to ensure the boiler operate safety and efficiently.
2) Complete gas manifolds and protection system, including filter, pressure regulating valve, and solenoid valve, etc., to ensure the safety performance of fuel.
3) Reliable boiler auxiliaries and multiple safety protection devices, such as pressure controller, pressure transmitter, water level alarm, and safety valve, etc.
6. Convenient Maintenance
1) There are manhole and inspection hole on the boiler, convenient for boiler internal installation, inspection and clean.
2) Membrane wall effectively reduce refractory brick quantity and maintenance workload.
