Product Description
SZS Series Double Drum Oil and Gas Fired Steam Boiler
SZS series double drum oil & gas fired steam boiler is double drum, longitudinal type D-form layout, fast loading water tube boiler. This series of boiler are made of upper boiler drum and lower boiler drum, membrane wall, convection tubes and condenser, the fuel was burning in boiler furnace, flue gas discharge into chimney from convection tubes and waste heat recovery device. By using mechatronic structure, the performance being in the leading domestic level.
Product Feacture
1. Advanced Control System:
Full automatic control, user just need press the start button, and then boiler will start running according with setting program. Load control, automatic feed water etc. are all automatic operation, in order to meet the user's requirements.
2. Accord with Environmental Protection:
Large furnace area, and with high quality and reliable imported burner, to make the fuel can burning fully, and also greatly reduce the harmful ingredients of flue gas, testing by relevant department show that our oil and gas fired boiler meet with national most strict environmental requirements, can meet constantly improving environmental requirements.
3. Wide Variety of Applicable Fuel:
Large furnace area, fuel burning fully, particularly suitable for low calorific value fuels, such as coke oven gas, blast furnace gas etc. The burning effect of high calorific value fuels are much better, such as natural gas, liquefied gas etc.
4. Reasonable Structure:
Set front water wall at front of boiler furnace, convenient for fixing the head of burner, to ensure the water degree and cooling near the burner, contribute to eliminate the carbon deposition of burner, so that the fuel can combust more
5. Easy Maintenance:
Set explosion door, fire hole and inspection door on boiler furnace wall, set manhole at front and back of boiler barrel, convenient for maintenance boiler
