Pressurized fluidized bed combustion (PFBC) topping combustor apparatus of one method and such plants in the power generation plant

摘要

(57) Abstract Rise stand die namely topping (topping) combuster 7 of the compressed fluidized bed combustion (PFBC) generation of electricity plant in order the flue gas from the combuster of the generation of electricity plant to lead via the topping combuster, has the 1st chamber 22 which is formed. The means 8 which are supplied the fuel gas, the topping combuster and at least vis-a-vis one burner 28 are laid out, the burner burns up the fuel gas in the topping combuster and making the gas mix which then it occurs with the flue gas, in order to reinforce the temperature of the flue gas, is constituted. The topping combuster, furthermore, is laid out in side of the 1st chamber and 22 possesses one which is separated from the flue gases current with that 2nd chamber 27 at least. The above-mentioned means are formed, in order to supply the fuel gas to the 2nd chamber, and burner 28 is formed in order to make the burnup of the fuel gas cause with 1st zone 29 of the topping combuster which is categorized to the 2nd interior. As for long-cherished desire, in addition, using the topping combuster, temperature of the flue gas from the combuster of the aforementioned PFBC generation of electricity plant it regards also one manner in order to rise.
