The SZS gas/oil double-drum horizontal chamber combustion boiler consists of upper and lower drums, membrane water wall, burner, superheater, convection pipe bundle, condenser, and dirt separator. Its furnace water wall and convection flue adopt a membrane wall structure, eliminating the need for refractory bricks. With advantages such as energy savings, high efficiency, environmental friendliness, short installation cycle, simple operation, and comprehensive protection, it meets the needs of industrial heating and small power station heating supply and has become a popular boiler type on the market.

It is a quick-assembled or bulk water tube boiler with a convection tube bundle on the left and a combustion chamber on the right. During the heating process, the flue gas produced by combustion in the chamber enters the combustion chamber and convection tube bundle through the smoke outlet at the end of the furnace, then passes to the economizer and condenser, which are made of finned tubes, and finally discharges into the air through the flue and chimney. The use of the economizer and condenser reduces exhaust gas temperature, improves thermal efficiency, and lowers fuel consumption.

FEATURE

  • Natural circulation structure: Double drum, vertical type, D-type layout, offering large capacity.
  • Membrane water-cooled wall: Adopted for front and rear walls, effectively extending service life.
  • Explosion-proof door: Installed at boiler tail to ensure operational safety.
  • Automatic control system: Programmable control with comprehensive functions including water supply, combustion adjustment, oil temperature control, steam overpressure protection, gas pressure protection, leakage detection, purging, flameout protection, and interlocking safety.
  • Insulation layer: Aluminum silicate fiber with good thermal insulation performance and light weight.
  • Economizer at boiler tail: Effectively reduces exhaust gas temperature and improves energy efficiency.
  • Full instrumentation: Water level gauge, level alarm, pressure gauge, electric contact pressure gauge, pressure controller, and flow meters, providing high/low water level alarms, low water level interlock, overpressure alarm, and overpressure interlock.
  • Imported burner: Original Italian Baltur burner with high automation, enabling fully automatic control including pre-purge, ignition, firing rate adjustment, shutdown, and flameout protection.
