Solid Fuel Fired Indirect Hot Air Generator Working Concept

The Solid Fuel Fired - Fluidised bed - Indirect Hot Air Generator works on the principle of Air to Air Indirect Heat exchange.



Highly efficient combustion and heat exchange are the corner stones to success of such equipment.
High end electronics and sophisticated control system makes operation extremely easy and simple at the same time providing ruggedness to the system.

Indirect Hot Air Generator Salient Features

  • We cater to Industries requiring Pure, Clean, Hot Air for Spray Driers, Spin Flash Driers, Rotary Driers, Fluidised Bed Driers, Tunnel Driers, Room Driers, Drum driers and many more.
  • Extremely rugged plants and precise automation to ensure same plant can operate at 300deg C and immediately can be shifted to operate at 130deg C without any changes in the system.
  • Turn down ratio of 33% and in special cases even upto 30% to ensure flexibility of plant operation.
  • Our Indirect Hot Air Generator systems have a Thermal efficiency of over 82%. Thus ensuring less fuel consumption
  • Highly Automated Plants with PLC based controls, VFD controlled Motors, PID controllers and sensors for consistent parameters
  • Easy and continuous operation of our systems without unplanned stoppages.
