Process for generating electricity in a pressurized fluidized-bed combustor system

Patent ·
OSTI ID:6828409

This patent describes a method of generating electric power from coal using a pressurized fluidized-bed combustor system. It comprises: supplying coal in a feed slurry comprising water, coal and a sulfur sorbent to a combustor; combusting the coal with air in a pressurized combustor chamber in the combustor to produce a flue gas; controlling the combustor temperature by varying an amount of excess air and water supplied to the combustor.
