Title:
A PRESSURIZED REACTOR SYSTEM AND A METHOD OF OPERATING THE SAME
Document Type and Number:
WIPO Patent Application WO/1995/027173
Kind Code:
A1
Abstract:
A method and apparatus are provided for operating a pressurized reactor system (1) in order to precisely control the temperature within a pressure vessel (3) in order to minimize condensation, and to prevent the temperature from reaching a detrimentally high level, while at the same time allowing quick heating during start-up. Gas is circulated from one part of the inside volume to another to control the temperature of the inside volume, for example by passing the gas through an exterior conduit (7) which has a heat exchanger (8), control valve (9), blower (10) and compressor (11) associated therewith, or by causing natural convection flow of circulating gas within one or more generally vertically extending gas passages, containing heat exchangers, flow rate control valves or the like, entirely within the combustion vessel. Preferably, inert gas is provided as circulating gas. The inert gas may also be used in emergency shut-down situations, when reaction gas supply to the reactor is cut off, and inert gas is introduced into the reactor.
