the 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.

D-type layout

Compact structure, small volume

Good flame fullness.

Membrane water wall structure

this boiler is a quick-assembled,the convection tube bundle on the left and the furnace on the right. during heating process, the flue gas generated by furnace combustion enters combustion chamber. Convection tube bundle area from the smoke outlet at the end of the furnace, then turns to economizer and condenser made of finned tube, and finally passes through flue and chimney.

BoilerFeature

1. this kind of boiler adopts the structure of double longitudinal drums and D-type furnace. Water tube design, the economizer and other auxiliary heating surface are fixed in the rear. The combustor is located on the front wall. The convection tube bank and rear heating surface from the back of the furnace, and then into air through the chimney.

2. Boiler capacity from 4-60ton/hr, pressure up to 50 bar

3. Body Structure Features: for the double drums longitudinal D-type boiler, the pressure body has a good state of stress. Drums and other important pressure parts won't be radiated and eroded by high temperature flame. Pressure parts, with small thermal stress, can stretch out and draw back freely, and can reach higher safety margin.

4. Auto protect, long-distance control, safety operation.

this steam boiler is widely used in chemical industry, plastics industry, coatings and automotive industries, bitumen industry, construction equipment industry, shipbuilding industry, apparel clothing, washing, ironing, the pharmaceutical industry, biotechnology, food industry, sauna and beauty, hotels, restaurants, sports, fitness and other places where need energy.

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.
