Water Tube Oil Gas Fired Boiler

Overview

SZS boiler is gas fired(oil fired) boiler with three pass return water tubes, also called fast-assembled water tube boiler. It adopts double-drum "D-type" arrangement, full water membrane wall structure, compound water circulation.

• Fuel: natural gas, lpg, cng, biogas, diesel oil, heavy oil, dual fuel

• Capacity: 4-50 ton, 300-3500hp, 2.8-35mw

• Rated Pressure:1.0mpa/1.25mpa/1.6mpa/2.5mpa/3.0mpa/3.82mpa (30psi-600psi)

• High steam temperature up to 450˚C

Application

For saturated steam, superheated steam or hot water supply, in food, beverage, refining, petrochemical, pulp and paper, mining, manufacturing, utilities and other industries.

Protective Function

• 5 Stage Interlock Protection. Water level protection, flame out protection, pressure protection, exhausted smoke over temperature protection, design with the 5th water level detector;
• Automatic operation of the burner ignition, flameout, big/small fire switch;
• Voltage and power supply abnormality protection function;
• Steam quality protection;
• Water quality protection (dosing device and TDS system optional)

• Leakage protection.

Advantages

1. D-type offset furnace has large furnace space, good flame filling, and sufficient combustion;

2. D-type double drum with compact structure, quick installation.

3. Pure water pipe + large upper and lower drum design, rapid pressure increase, saving operating costs;

4. Larger water volume + steam-water separation device, high steam quality;

5. Adopt full water membrane wall furnace, which has good sealing performance and good heat transfer performance.

6. Double-layer 120mm aluminum silicate insulation, the outer temperature does not exceed 45 degrees Celsius

7. The tilt angle design of the upper and lower headers makes the water flow smoother and prevents the generation of dead water areas.

8. Natural water circulation princinple, low water quality requirements and has few faults.

9. The tail is equipped with a flue gas condensation device to reduce the flue temperature and improve the thermal efficiency of the boiler;

10. Built-in soot blower for effective cleaning of superheaters and other heat transfer surfaces

11. Safe operation for over 20 years
