Abstract
A novel process and apparatus for power generation from biomass and other carbonaceous feedstocks are provided. The process integrates a pulse combustor steam reformer with a gas turbine to generate electricity such that (i) efficiency is higher than those of conventional and current advanced power systems, (ii) emissions are lower than those proposed in the new environmental regulations, and (iii) performance is comparable to that of combined cycle, even though a bottoming cycle is not included here. The pulse combustor steam reformer generates a hydrogen-rich, medium-Btu fuel gas that is fired in a gas turbine to generate electricity. The apparatus may be configured to produce only power or combined heat and power.
Claims13
A process for producing electricity from carbonaceous materials comprising the steps of:
- providing a fluidized bed containing a particulate material and a fluidizing medium, said fluidizing medium comprising steam;
- combusting a fuel source in a combustion device to form a combustion stream, said combustion stream indirectly heating said fluidized bed;
- feeding a carbonaceous material to said fluidized bed, said fluidized bed being at a temperature sufficient for said carbonaceous material to endothermically react with said steam to form a product gas stream;
- feeding said product gas stream to a gas turbine, said gas turbine combusting said product gas stream in order to rotate a turbine and generate electricity, said gas turbine producing a flue gas stream;
- combining an air stream with the product gas stream prior to combusting the product gas stream in the gas turbine, the air stream being preheated by the combustion stream exiting the combustion device;
- preheating at least a portion of the flue gas stream exiting the gas turbine by the combustion stream exiting the combustion device;
- and
- feeding at least a portion of said flue gas stream to said combustion device for combustion with said fuel source.
