Fuel reactivity and release of pollutants and alkali vapours in pressurized combustion for combined cycle power generation

The recirculation of flue gases in pressurized combustion units offers possibilities for more efficient, environmentally-friendly burning of fossil fuels. Many aspects remain to be studied, however. In particular, the alkali metals present in the flue gases, both in the vapour phase and in dust particles, are known to be detrimental to the turnine blades used in modern power plants.

The objective of the research was to examine the reactivity of solid fuels in direct pressurized combustion facilties with recirculated flue gases. Fuel behaviour at pressures up to 20 atmospheres and the influence of flue gas recirculation (mainly CO2) on reactivity was studied. Pollutant emissions and alkali release were determined for a series of pressurized reactors for the same solid fuels.
