SZS series steam boiler is a typical D-type double-pot tube vertical water-tube boiler. According to the boiler capacity, there are two kinds of quick-fix type and assembled type. The quick-fix type is below the rated evaporation capacity of 20t/h, and the assembled type is above 50t/h.

this steam boiler is composed of upper and lower boiler tube, (superheater), furnace chamber, water cooling wall, convection tube bundle and waste heat device. the combustion is arranged on the front wall, and the flue gas is discharged into the chimney through convection tube bundle and waste heat device after combustion.the water cooling wall of the boiler is arranged in dense row or membrane type, the flue gas partition wall is arranged in membrane type and finned tube type, the inner guard plate is fully closed welded structure, and the boiler is equipped with explosion-proof door and other safety devices.

the steam boiler is a typical double - drum vertical - type "D" layout quick - installation water tube boiler.the burner is arranged in the front wall. after the fuel is burned in the furnace, the flue gas is discharged into the chimney through the convection tube bundle and the economizer.

Boiler characteristics:

the boiler adopts double drum "D" type layout, compact structure, small floor space, good flame filling.

the steam boiler adopts the lower support way, can freely expand upward.

the water wall of the furnace and convection flue all adopt membrane wall structure, good sealing and effectively reduce the use and maintenance of firebrick workload.

the outer packing of the boiler adopts the press guard plate, the appearance is beautiful, beautiful.

the furnace of the boiler is equipped with inspection hole, provides convenience for use, maintenance.the furnace top is provided with explosion-proof door.

the use of high thermal resistance material as insulation, heat preservation performance is good.

for the tail arrangement of economizer, heat transfer effect is good, can effectively reduce the smoke exhaust temperature, boiler thermal efficiency is high.

Therefore the boiler has enough space for soft water, to ensure that the boiler parameters are stable.SZS large industrial steam boiler factory in Guyuan, Ningxia sells low nitrogen oil-fired boiler directly

Full automatic burner, high combustion efficiency and ignition program control and overpressure, extinguishing protection function.

We will adopt continuous electric water supply adjustment, and with high and low water level alarm, overpressure alarm interlocking protection function.

Adopt quick installation structure, can effectively shorten the installation time.
