Back Furnace Type

Product Description Technical Data Documents Fiyat Listesi
USAGE AREAS
■Water piped back furnace provides more savings and superheater unit could be placed inside the furnace, ■ Placed that need high efficiency,
■ Places that have high steam capacity, ■ Responds to all kind of working conditions,
■ Places that instantaneous steam consumption, ■ Eco-friendly due to 3-pass design,
■ Unattandant and constantly running, ■ Can be used at all places, that need to generate steam.
 
ADVANTAGES
■  Since the fuction of burning lays on rear furnace, 2 and 3 stacks are at the same height, therefore the gas passageway is longer. ■High efficiency due to the low flue outlet temperature,
■ Low counter pressure in the boiler, ■Provides lower nitrogen oxide emissions with 3-pass design,
■ Reacts to instantaneous steam traction, due to high steam capacities, ■Temperature of the flue gas reducing condensation temperature provides high efficiency with economizer,
■With the addition of superheater unit can obtain high temperatures at low pressure, ■Radiation loss prevented by rear smoke box and water cooler system,
■Staircase and platform provides easy and safe acces between floor levels and boiler, ■ Heat loss is prevented by mesh wire rockwool insulation
■Alumina-doped refractory is resistant to high temperature,durable and insulated ■Simple to operate and to maintain,
■Can be used with different types of burners,  
 
DISADVANTAGES
■ At first running, consumed more energy because of the large volume steam, ■ Physical size maybe an issue.
