SZS series steam boiler is designed with longitudinal double drums and " D " type chamber structure. Furnace is placed on the right and convection tube bank is on the left, super heater is arranged at convection tube bank. The body is fixed on the basement by middle and both end flexible supports and make the boiler expand horizontally sideways. Around the furnace is membrane water cooling tube wall. Furnace and tube bank are totally separated by the membrane water tube cooling wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, convection tube bank area and then from left front part enters spiral fine coil economizer and condenser, and finally is discharged to atmosphere through chimney.

Boiler advantage

1. It adopts double drum & "D" type layout, compact structure, small floor space and good flame fullness.

2. The furnace adopts a modular water-cooled wall structure, and the boiler adopts an airtight inner protective plate with a fully enclosed welded structure, and the furnace wall has a good airtightness.

3. The boiler layout has a large heating surface area, and the design has a large enough steam and water space to ensure the stability of the boiler parameters.

4. A flue gas condensing recovery device is arranged at the tail, which can effectively control the exhaust gas temperature and the boiler has high thermal efficiency.

5. The high thermal resistance material is used as the thermal insulation layer, and the thermal insulation performance is good. The outer layer of the boiler adopts a pressed guard plate, which has a beautiful and beautiful appearance.

6. Adopting quick installation structure, the whole boiler is designed on a strong rigid base, which is convenient for installation and transportation.

7. The furnace is equipped with inspection holes, which provides great convenience for use and maintenance. There is an explosion-proof door on the stove top.

8. Fully automatic burner is adopted, and the water supply adopts continuous electric regulation, and the combustion efficiency is high. And has multiple protection functions, safe and reliable operation.

Technique Parameters 

Boiler Usage

Industrial fields: thermal power plants, shipyards, petrochemical and other precision instrument manufacturers, medicine, bioengineering, food industry baking and other process steam supply; places where hot water is needed in the factory.

Living areas: steam use in laundry rooms in hotels, steam disinfection in hospital equipment, steam use in canteens, saunas and beauty salons; residential, schools, office buildings, hotels and other places that need heating; hot water supply for hotel baths and other hot water.

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.
