Product Discription
Series Double Drum Oil and Gas Fired Steam Boiler
The series of two -drum gas -fired steam boilers are two -drum, long -running boilers with fast water supply. The series of boilers consists of upper and lower drums, membrane coils, convection bushes and condensers. Fuel is burned in the furnace of the boiler. Liquid gas is discharged into the chimney from the convection tanks, and waste heat recovery device. With Mechatronics structure, performance is at the leading level in China.
Product Features
1. Miscellaneous applicable fuels:
The furnace zone is large, fuel combustion is sufficient, especially suitable for low calorific fuels such as coke gas, blast furnace gas, etc. The combustion efficiency of high calorific fuel is better, such as natural gas, liquid gas, etc.
2. Overload capacity:
The heating area is large, the furnace area is large, the output is strong, and has a certain overcharging capacity.
3. Reasonable structure:
The front of the water wall for the boiler is easy to attach the burner head, provide the water level and cooling at the burner, help to eliminate the carbon footprint in the burner and make the combustion of the fuel more complete.
4. Easy to maintain:
The blast -proof door, fire -resistant hole and handheld door are on the wall of the boiler, and the handheld hole is on the front and back of the boiler to facilitate the revision of the boiler.
5. Reducing heat loss:
A thick insulation layer is assumed to reduce the heat loss of the boiler and to improve the heat efficiency.
6. Long life and durability:
Excellent professional design, advanced production technology, strict quality control and control are the quality assurance of each boiler. The normal life of the boiler is more than twenty years.
