It is disclosed herein a desulfurisation method according which the exhausts derived from the combustion area of the combustibles (boiler 1) are conducted from the exit (1α) to the heat exchanger 2 and therefrom to the first electrostatic filter 3 where the maximum ratio of dust and ashes is retained; in the sequel, the mixture of our material (GREEN LIME) which is stored up in the silo 5 is conducted to the exit of said filter as well as to the position 4 inside the duct of the combustibles 4α. The GREEN LIME injection depends on the number of the electrostatic filters or sack filters in use, as follows: 1) injection to positions (6,7) or to both positions in case that one single electrostatic filter 3 exists; 2) injection to positions (7,6,4) or, alternatively, to positions 4, and 6 or to positions 6 and 7 and/or solely to the position 4 or 4 and 7, if two electrostatic filters exist. The used material can be reused in the aforementioned positions (recycling). |
