VTF SERIES
The VTF-series, vertical four pass F.B.C fired Thermic fluid heater is designed for maximum efficiency, using a variety of Fuel Like Crushed Coal, Pellets, and Crushed Briquettes. VTF- Series Thermic fluid heater is High Temperature Working Process.
The combustion Furnace system for free flow fuels consists of fuel feeding threw screw feeder handling and stoking equipment, in refractory lined chamber, air and flue gas handling system (including I.D. fan and F.D. fan) with blowers and pollution control equipment. The furnace construction is done on site (only for bricks works). It includes foundation, fabrication and erection of supporting structure, building up refractory chambers, fixing up firing doors, ash doors, access doors, air plenum chamber and nozzle.
Operating Range
- Capacity – 4,00,000 Kcal/hr. To 50,00,000 Kcal/hr.
- Fuel-Crushed Coal/ Agro Pellet/ Crushed Briquette
- Overall efficiency of 78 % (+/-2%) on GCV with APH.
