HYDROGEN GENERATOR Russian patent published in 2005 - IPC

FIELD: power equipment; generation of hydrogen both in stationary plants and in transport facilities.

SUBSTANCE: proposed hydrogen generator is made in form of chemical reactor generating hydrogen by hydrolysis, i.e. by decomposition of water by use of solid reagent and hydrolysis reaction of heterogeneous nature proceeding on solid agent surface. Hydrogen thus generated shall be used in power plants working on fuel elements. Hydrogen may be also used for cutting and welding of metals. Hydrogen generator working on hydrolysis exothermic reaction includes reaction vessel with hydrogen supply main and heat exchanger for removal of reaction heat. Generator is also provided with two hydrogen accumulators fitted with pressure sensors; each hydrogen accumulator is pneumatically connected with reaction vessel through inlet valve and with hydrogen supply main through outlet valve; hydrogen accumulators are made in form of hermetic reservoirs partially filled with water and hydraulically interconnected through heat exchanger used for removal of reaction heat and water flow regulator connected with pressure sensors fitted in hydrogen accumulators. Provision is made for autonomous operation of generator which may be cooled in automatic mode.

EFFECT: enhanced operational reliability at simple control algorithms.
