Combustion system

The combustion system, consisting of the grate system and the furnace, is the technological core of a waste-to-energy plant. We differentiate between conventional combustion system, the combustion system combined with flue gas recirculation and the SYNCOM-process.

 

These three combustion systems differ in terms of the composition of the combustion air provided:

 

  • Conventional - underfire and overfire air is being fed to the combustion process
  • Flue gas recirculation - most of the overfire air is replaced with recirculated flue gas, after fly ash removal
  • SYNCOM - part of the underfire is enriched with pure oxygen; most of the overfire air is replaced by recirculated flue gas

 

The grate systems used are the MARTIN reverse-acting grate Vario, the MARTIN horizontal grate and the MARTIN reverse-acting grate SITY2000.
