A fluidized bed system in use with independent combustor

The present invention relates to a fluidized bed indirect gasification system with an independent combustor which enables to obtain high quality of synthetic gas through effective indirect gasification of low grade fuels having various constellations such as biomass, waste, coal, etc. According to the present invention, the system comprises a pre-process unit having a selector (500); a gasifier (300) supplied with a first fuel selected in the pre-process unit; a combustor (100) supplied with a second fuel selected in the pre-process unit; and a riser (200) for connecting the gasifier (300) and the combustor (100) and having temperature-increasing and transporting functions of a bed material therein.

Fluidized bed reactor apparatus and related gasification system

A process and pressurized, gasification reactor apparatus for converting combustible carbon containing materials such as coal char and other carbonaceous solids or carbonaceous solids/heavy oil combinations to an intermediate heating value fuel gas. The gasification reactor includes an insulated fluidized bed reactor chamber, an upper reactor housing for a freely suspended bayonet bundle type heat exchanger for (a) superheating incoming saturated steam and (b) cooling outgoing high temperature product gas, and a lower reactor housing structure which includes a free-floating, conically-shaped perforated plenum chamber. The superheated steam and oxygen are premixed with the plenum chamber before being pressure directed into the fluidized bed reactor chamber for mixture and combustion with the incoming combustible carbon containing materials such as coal char. After reaction of the superheated steam, oxygen and coal char in the fluidized bed reactor at temperatures ranging from 900° F. to 1750° F., the product fuel gases and associated particulate matter are cooled by steam flowing through the bayonet heat exchanger, the steam being superheated by this exchange. After discharge from the heat exchanger, the fuel gas product containing particulate matter is pressure directed into a conventional cyclone separator for (a) separation of the desired product gases and (b) return of the particulate matter for further recycling in the reactor chamber. Undesirable ash clinkers are gravitationally and pressure directed out of the reactor chamber through a central ash withdrawal pipe.
