Patent FR-2668815-A1 (FR)
Inventor: ROGER SINQUIN
IPC: F23J15/02
Filed: 1990-11-02
Abstract: The process is implemented in a boiler (1) comprising a hearth (10) containing a fluidised bed surmounted by a post-combustion chamber (13). The combustion gases follow alternately rising and descending paths (16, 17, 19 and 21) where they cool in contact with walls (35, 36, 37, 38, 39) equipped with water pipes. Limestone is injected (at 28) into the bed (10) to fix the sulphur oxides and halogen compounds, and a jet of powdered lime, which neutralises the halogen compound residues, is injected (at 20) at the beginning of the third path (19); the flying particles deposited (at 18) are recycled into the hearth (10). The temperature of the bed is maintained between 800 DEG and 900 DEG C and the secondary air injection is controlled to give an oxygen content in the combustion gases of between 5.5 and 7.5 %, to minimise the formation of nitrogen oxides, dioxins and furans.
