ABSTRACT:
A hydro-pressurized fluidized bed combustor having an uptanding shell and an entry at its bottom for admission of feedstock. The feedstock passes through a conduit surrounded by a heat exchanger. Inside the shell an entry conduit is outwardly flared in the upward direction to furnish a controlled expansion entry feeding into the fluidized bed. The entry conduit has a plurality of tuyeres in its peripheral wall. An injector pump feeds the feedstock into the entry. A weir above the entry conduit keeps the height of the bed constant within the combustion during operation.
