SZS 10 ton 20 ton 30 ton water tube fuel natural gas diesel heavy oil fired industrial steam boiler for grain and oil factory

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 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.

Features of Low Cost szs series gas/oil fired steam boiler

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.

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.
