Title:
PRIMARY REACTOR LIQUID WATER AND AIR INJECTION FOR IMPROVED MANAGEMENT OF A FUEL PROCESSOR
Document Type and Number:
WIPO Patent Application WO2004013482
Kind Code:
A3
Abstract:
A method is provided to inject liquid water into the normal stream of fuel, superheated air and superheated steam entering a primary reactor of a fuel processor. The injection location is in the steam supply line where superheated steam vaporizes a majority of the liquid water, preferably prior to injection into the primary reactor. Steam supplied by a vaporizer may temporarily lag desired steam production due to system up-power transients or startup conditions, coupled with vaporizer thermal lag time. Injection of liquid water overcomes this temporary deficit of steam. Additional air is also supplied as needed to improve reactance for a given steam volume/temperature. Injection rate or volume of the liquid water and air may also be based on one or more measured variables of the primary reactor.
