Definitions

  • this invention will permit to blow primary air in prefixed and independent adjustable quantities below the mass of material to be incinerated, in various sections along the longitudinal furnace axis, while a controlled amount of secondary air is directly let into the combustion chamber, in the free space above the fuel bed, thus obtaining an optimum combustion which is carefully controlled during all process stages.
  • the combustion air is blown in through a longitudinal piping system 10, mounted along the peripheral shell plating 1; these pipes are placed in parallel and at equal distance, having their axis parallel to the generating line of the shell, as shown in fig. 1 and 2.
  • each valve in each furnace zone S1, S2 and S3 is adjusted twice: once to control the primary air flow rate below the fuel bed and once to adjust the secondary air flow rate in the upper furnace zone occupied by air and gaseous combustion products.
