16 Bar D Type Water Tube Boiler Steam Drum Design Gas Condensing Boiler

China supplier SZS D type Water fired steam boilers with double drum for sale

SZS series oil-gas-steam/hot water boiler introduces advanced German industrial boiler safety control system, adopts PLC and independent chain protection system design, as well as all-chinese touch screen and intelligent, convenient human-machine operation interface of the boiler to ensure high safety, high reliability, automatic and intelligent boiler control and operation.

High efficiency and energy saving:
1. The boiler is equipped with internationally advanced imported automatic burner to realize efficient and automatic combustion
2. Micro-positive pressure operation, boiler combustion efficiency is higher, power consumption is low, and operation cost is reduced
3. Full-film wall structure, low temperature on the inner wall of the furnace wall, small heat loss, good sealing, high thermal efficiency of the boiler
4. The tail part is equipped with high-efficiency energy-saving device, which further reduces the smoke discharge temperature and improves the boiler's thermal efficiency

Product structure:
1. Three-way structure: the international popular pot shell three-way, full wet back structure, combustion chamber large volume design, make the combustion more fully.
Micro positive pressure in the fuel in the furnace combustion, high temperature along the furnace flue gas by back into the combustion chamber back turn 180 ° into the first flue tube bundle, the compression type smoke box before you turn 180 ° in the second, through the convective heat transfer back into the atmosphere.
2. Corrugated furnace bladder: the combustion chamber adopts full corrugated furnace bladder structure, which not only strengthens the disturbance of smoke, but also increases the radiation heat transfer area;
It not only increases the rigidity of the furnace, but also effectively reduces the expansion stress of the furnace.
It not only enhances the heat transfer effect, but also promotes the combustion of fuel in the furnace.
3. Unique smoke pipe and pipe plate welding process: the use of pre-expansion and then full welding, and then expansion of the advanced technology, not only prevent pipe gap corrosion, but also enhance the welding strength;
The screw pipe with high heat transfer coefficient is adopted to strengthen convection heat transfer effect, reduce smoke discharge temperature and improve boiler heat efficiency.
4. Symmetrical movable hinged front and rear smoke doors: easy to open, repair and clean.
