SZS Series Oil And Gas Fired Boiler

Type: Steam Boiler/Hot Water Boiler Capacity/Hot Power: 4 - 90ton /14 - 58MW Pressure: ≤1.6MPa Fuel: Natural Gas, Light Oil, Heavy Oil, Biogas, Blast Furnace Gas Application: Industrial Steam and Hot Water Supply


Brief Introduction:

SZS series oil and gas fired boiler is a packaged water tube boiler with double drums and D-type layout. It has lots of advantages such as sufficient burning, no pollution in the emission, convenient operation, easy installation etc. Besides, SZS series boilers have the features such as high thermal efficiency, high output, better load adaptability, and high automation level as well as safe and reliable operation. It is an ideal environmental protection product with high efficiency, low energy consumption and less pollution which will play an important role in the application field of thermal energy equipment in future.


SZS series oil & gas fired boiler is mainly used in centralized heating, industrial steam and hot water supply.

  • D-type Double-Drum style with compact structure, less occupied area, good flame fullness which is better for low nitrogen combustion and low nitrogen emission.
  • With totally automatic burner and full set of safety protection device, thus automatic safety operation can be guaranteed.
  • Gas-tightness inner guard board with totally-enclosed welding structure which ensures a good sealing performance of the furnace wall.
  • The heat exchange surface area of the boiler and the space for water and steam are large enough to make sure the boiler parameters are stable.
  • The rear section of such boiler is equipped with flue gas condensing and recovery device which can effectively control exhaust gas temperature so that to improve boiler thermal efficiency.
  • Adopts high heat resistance material as adiabatic layer which brings a good thermal insulation property; the outer shell of the boiler adopts pressed guard board which makes the boiler looks delicate.
  • Adopts packaged structure; the whole boiler is fixed on the steel base with strong rigidity. Such structure provides convenience for installation and transportation.
