Sectional Axonometric Drawing
�SZS series oil and gas fired boiler is a packaged water tube boiler with
longitudinal type double drums and D-shape layout. It has lots of advantages
such as sufficient burning, no pollution in the emission, convenient operation, easy
installation etc. Besides, the 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.
Capacity: 4 - 35 t/h /14 - 58MWDesign thermal efficiency: 92—95%Applicable fuel: Natural gas, light oil, heavy oil, gas, etc
Application: �Large central heating and residential heating in winter
Product introductionProduct introduction
SINCE���1945SINCE���1945
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.
Environmental and clean1
With totally automatic burner and full set of safety protection device, thus
automatic safety operation can be guaranteed.
Safe and reliable2
Gas-tightness inner guard board with totally-enclosed welding structure which
ensures a good sealing performance of the furnace wall.
Reasonable structure3
Product featuresProduct features
a. 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.
b. 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.
c. Adopts high heat resistance material as adiabatic layer which brings a good
thermal insulation property.
High efficiency and energy saving4
