SZS series oil-fired and gas-fired boilers are double-drum vertical "D" type quick-install water tube boilers.It is composed of upper and lower boiler tube, membrane water cooling wall, convective tube bundle and flue gas condensation recovery device. after the fuel is burned in the furnace, the flue gas is discharged into the chimney through the convective tube bundle and flue gas condensation recovery device.Full combustion, pollution-free emission, convenient operation and installation are realized.High thermal efficiency, large output, strong load adaptability, high degree of automation, easy to operate, safe and reliable operation, is an ideal high efficiency, low consumption, low pollution green environmental protection products.

Performance advantages of Steam boiler

(1) the design of super large combustion chamber enables complete combustion of fuel with high combustion efficiency and low pollution.

(2) the boiler has a surplus heating surface and a large enough space for soft water to ensure the stability of boiler parameters.

(3) Explosion-proof door is set on the top of the furnace, which can discharge the energy released by chamber explosion.

(4) the water supply adopts continuous electric adjustment, and has the function of alarm of high and low water level and interlocking protection.

(5) Some furnaces are equipped with water-jet temperature-reducer, which is sensitive in temperature regulation and has a large range of temperature regulation.

(6) Considering the overall transport requirements of the boiler, the boiler design layout is more compact addition, the boiler adopts quick installation structure, which can effectively shorten the installation period.
