Brief Intro :SZS series water tube boiler has double drums, and arranged as “D” shape, adopts membrane cooling wall, has the characteristics of high steam quality, sufficient output, and high thermal efficiency (97%), etc.

SZS series boiler body is a double-pot barrel, longitudinal-type, room-burning D-type layout structure, with furnace chamber on the right and convection tube bundle on the left.The movable supports at the middle and both ends of the boiler barrel are fixed on the body chassis, and the whole boiler is guaranteed to expand to both ends.Furnace for narrow spacing around the membrane water wall tube, furnace on the left side of the membrane water wall of furnace and the convection bank completely sealed off, convection bank area at the back of the cuo column structure for diarrhea, a front along the column structure, out of the smoke at the end of the combustion chamber of a stove or furnace to produce gas from the furnace mouth into the burning chamber, convection bank area, and then from point to spiral fin tube economizer of boiler on the left side of the front and condenser, finally enter into the chimney flue discharge into the atmosphere.

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.

Technical Parameter

1. The brand of burner?

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

2. 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.

3. 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!

4. 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.

5. 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.
