Hot Gas Generators

ENEVA hot gas generators are direct-fired systems designed for applications where the mixing of combustion products with process air is acceptable. These applications typically belong to heavy industry where hygienic requirements are not a concern.

These systems are specifically developed to meet high-capacity and reliable hot gas demands in industries such as cement, chemicals, and similar heavy industrial processes.

  • Direct-fired high-efficiency hot gas generation
  • Outlet gas temperatures of 500 °C and above
  • High thermal capacity up to 30 MW per unit
  • Improved efficiency through integration of process return air

In ENEVA hot gas generators, fuel is combusted under optimal conditions داخل a specially designed, cooled combustion chamber (furnace).

  • Hot flue gases generated by combustion are mixed with cooling air flowing outside the combustion chamber to achieve the desired outlet temperature
  • Outlet temperature is precisely controlled באמצעות the amount of cooling air introduced into the mixture
  • The same cooling air also provides thermal protection by cooling the combustion chamber
  • Minimal refractory design enables faster commissioning
  • Lower maintenance costs compared to conventional refractory-lined units

Main application areas:

  • Cement plants (cement, raw meal, and coal drying / grinding systems)
  • Chemical and mineral processes (detergents, powder coatings, etc.)
  • Ceramic factories (powder production via spray dryers)
  • Brick and refractory manufacturing plants

In these applications, HGG systems provide advantages such as high capacity, simple operation, and reliable performance.
