High pressure Coal Fired Steam Boiler Components Enamel Tube Air Preheater Wiht Advanced Technology
Product Description
1. A device,which increases the tempurature of air before it supply to the furnance using heat from flue gases passing through chimney.
2. The heat carried with the flue gases coming out of economiser is further utilised for preheating the air before supplying to the combustion chamber.
3. An increase of 20 degree centigrade in the air temp.increases the boiler efficiency by1%.
4. It is a necessary equipment to supply hot air for drying the coal in pulverised fuel systems to facilitate grinding and satisfactory combustion of fuel in the furnace.
Adavantages
1. Preheated air increases combustion rate and then increases steam generations of boiler.
2. Due to higher temp. of air,furnace temp.increases,so low grade coal can be burnt efficiently.
3. Air heated by heat of exhaust gases.It reduces fuel consumptions.Therefore thermal efficiency of boiler increased.
