SZS Gas & Oil Water Tube Boiler

Capacity :10tph~50tph

Pressure :1.0 MPa~ 4.9 MPa

Fuel :Heavy oil, diesel, natural gas, LPG, etc.

Application : Textile mill, paper plant, food industry, laundry, hotel, etc.

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 type oil and gas steam boiler chamber water cooling wall and convection flue all adopt membrane wall structure, good sealing, high thermal absorption rate, and effectively reduce the use and maintenance of firebricks.The boiler adopts high thermal resistance material as insulation layer.Good insulation performance.Energy-saving condenser is arranged in the tail.Can effectively reduce the smoke exhaust temperature, boiler thermal efficiency is high.Ultra-low nitrogen automatic combustion machine, so that the smoke less harmful pollutants, noiseless operation.And has the ignition program control and overpressure, flameout protection functions, safe operation.

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.
