CWNS methanol-fired hot water boiler

CWNS type full-automatic methanol-fired hot water boiler is a fast-installed horizontal internal combustion three-pass fire tube structure. The offset furnace bile wet-back arrangement is adopted, and the high-temperature flue gas sequentially flushes the second and third return smoke pipes, and then is discharged into the atmosphere from the rear smoke chamber through the chimney. The boiler is equipped with world brand burners. It adopts advanced technologies such as automatic combustion proportional adjustment, automatic feed water adjustment, program start and stop, and automatic operation. It also has automatic protection functions such as operating water temperature control, over-temperature and over-pressure flameout. This type of boiler has the characteristics of compact structure, safety, easy operation, rapid installation, less pollution, low noise, high efficiency, etc. It is widely used in enterprises, hotels, hospitals, offices, civil buildings and other facilities for industrial steam and living and heating.

product description

CWNS methanol-fired hot water boiler

CWNS type fully active methanol-fired hot water boiler is a fast-installed horizontal internal combustion three-pass fire tube structure. The offset furnace bile wet-back arrangement is adopted, and the high-temperature flue gas sequentially flushes the second and third return smoke pipes, and then is discharged into the atmosphere from the rear smoke chamber through the chimney. The boiler is equipped with world brand burners, adopting advanced technologies such as active combustion proportional adjustment, active feed water adjustment, program start and stop, and active operation, and has active cherishing functions such as operating water temperature control, overtemperature, and overpressure flameout. This type of boiler has the characteristics of compact structure, safety, easy operation, quick installation, low pollution, low noise, high obedience, etc. It is widely used in enterprises, hotels, hospitals, office buildings, civil buildings and other facilities for industrial steam and living and heating.

1. Proprietary technology of Yongxing Boiler Full-wet back flashback chamber, the flashback chamber is connected with the rear tube plate, the boiler is fully butt-welded, with low stress and better quality.
2. Large-diameter corrugated furnace boiler combustion chamber is composed of large-diameter full-corrugated furnace furnace. The combustion space is large, the fuel combustion is effective, it is useful to absorb thermal expansion, and the radiation heating surface is large.
3. Sufficient heat power The total heating area of the boiler is sufficient, it can fully absorb useful heat, the exhaust temperature is low, the heat loss is small, the output is sufficient, and the obedience is high.
4. Strong heat load adjustment capacity. The pot diameter is large, the water capacity is large, the ability to adapt to load changes is strong, and the output is stable.
5. Effectively solve the problem of subcooled boiling of hot water boilers. The water return system of the hot water boilers has been scientifically arranged, which has increased the disturbance of the water side of the heating surface in the high temperature area, avoiding the signs of subcooled boiling in the lower part, and effectively solved the problem of high temperature zone pipes The problem of cracks at the ends of plates and tubes.
6. Multifunctional safety explosion-proof assembly The rear panel of the boiler is equipped with an explosion-proof assembly that communicates with the furnace to prevent the high-energy instantaneous release of fuel when the fuel is violently detonated in the furnace and can be actively reset. It also has a fire-viewing mirror and maintenance. The function of the channel, the adjustment of the combustion flame during operation, convenient furnace inspection and maintenance.
7. Convenient maintenance in the boiler. Manholes are provided on the top of the boiler, and unique hand hole assembly is provided in the middle and lower part of the front and rear ends of the boiler, which facilitates the assembly in the boiler and the inspection and cleaning of the bottom of the boiler.
8. Unique front and rear smoke box sealing The unique smoke box adopts double-opening smoke box door, which is easy to open, multi-stage labyrinth seal, special sealing material, good compressibility, effectively blocking the leakage of smoke, and can be reused.
9. Pressure, temperature cherish the boiler pressure, water temperature settings multiple control cherish, and super smoke temperature cherish, to ensure the safety of boiler operation.
10. Active control horizontal boiler controller adopts Siemens / Delixi electrical components for performance. The controller has three situations: popular type, Chinese and English menu type with liquid crystal display, and touch screen type with long-distance control of man-machine dialogue.
