An industrial heat generator is a special equipment for producing thermal energy from the combustion of various fuels.

The operation of this device consists mainly of periodically feeding fuel into the combustion chamber to maintain the required level. Nozzles directed to the base of the combustion chamber provide the combustion process using supplied air.

Fans installed in the casing of the solid fuel heat generator cool the outer casing of the appliance. The heated air from the chamber is discharged into the combustion chamber through vortices.

The main technical advantages of chip and pellet heat generators are as follows:

  1. The cylindrical vertical design of the equipment allows a smaller footprint as well as an efficient use of the combustion chamber volume.
  2. The unit is equipped with a special fuel control system.
  3. A uniform distribution of air over the combustion chamber’s internal circuit is achieved by spiralling the combustion gases and volatile particles.
  4. Diverting the gases through a battery cyclone reduces the amount of ash in the air stream.
  5. The solid-state heat generator can also be supplied with additional equipment for cleaning the pyro-air mixture of fly ash.
