Abstract
Abstract A process and apparatus for controlling the temperature of the fluidized bed in a thermal reaction furnace. An igniting flame is directed horizontally and radially at the fuel within the bed in the lower third of the bed above the grate. The ignition burner and fuel pipeline are arranged closely together and enter the furnace through a common fitting or flange. In operation, the ignition flame is ignited before fuel is fed to the fluidized bed.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
101 words
In a thermal reaction furnace for incinerating substances, the process comprising a. providing a fluidized bed of small, granular, solid particles, b. introducing combustion air to the fluidized bed to keep the bed above the fluidization point, c. igniting a flame before fuel is fed to the cold fluidized bed and directing said flame into the interior of the lower third of the bed, d. delivering to the fluidized bed in opposed relation to said flame substances to be incinerated, and e. feeding fuel to said ignition flame in parallel closely arranged fashion thereto after the ignition flame has burned reliably.
Claim 2
Dependent Claim
101 words

Claim 3
Dependent Claim
110 words
A thermal reaction furnace for incinerating substances comprising a. an upright incinerator housing, b. a grate in the lower portion of said housing to support a fluidized bed of small, granular, solid particles, c. means for feeding combustion air through said grate to keep the bed in fluid state, d. means for directing a flame radially of said housing into the interior of said bed in the lower third thereof, e. means in opposed relation to said flame means for delivering substances to be incinerated, and f. means arranged close to and in parallel relation to said flame means for delivering fuel to said flame after it has burned reliably.
