Zero Emissions Power Generation Boiler

Abstract

This is a zero emissions power generation boiler that can be used to drive a wide range of steam turbines, from 20 MW up to 1200 MW, creating dry steam pressure ranging from 1000 psi up to 4500 psi. It creates steam by burning liquid hydrogen with liquid oxygen, completely eliminating the emission of greenhouse gases, lethal poisons, and every form of pollutant. It employs high-pressure cryogenic fuel pumps, a water cooling system, an electronic sparking system, a double-wall cylindrical boiler with a hemispherical top, and a control system that employs electronic sensors, actuators, signal conditions, microprocessors, digital interfaces, and mechanical back-up systems. It can be used in new power plants or as a replacement for current boilers in existing power plants. It has the option of working as part of a combined cycle system and can employ steam reheat systems.

1 . First claim: This zero [harmful] emissions power plant boiler is a unique design that can produce enough steam to run turbines ranging from 20 MW to 1200 MW, at pressures of 1000-4500 psi, by means of burning liquid hydrogen and liquid oxygen, completely eliminating the emission of greenhouse gases, lethal poisons, and all known pollutants, in a system comprising:
 cryogenic fuel tanks   high-pressure cryogenic fuel pumps   rings of centrally-located burners   an electronic sparking system.   
     
     
         2 . Second claim: The boiler is a unique, double-walled cylindrical design with a hemispherical top capable of handling the high stresses involved, in which steam pressure is created in the central cavity, rather than in a system of piping along the sides, and is comprised of:
 an outer wall   an inner wall   a steam header at the top.   
     
     
         3 . Third claim: The boiler is cooled by a system of water pumps that send heated water at high pressure to rings of nozzles located between the burners and the walls, sending the water up into the central cavity where it becomes steam while cooling the walls and top of the boiler, in a system comprised of:
 cooling ponds   a water holding tank   a water pre-heat system   high-pressure reciprocating water pumps   rings of nozzles at the base of the boiler   
     
     
         4 . Fourth claim: The boiler system is controlled by a large series of sensors, actuators, signal conditioners, microprocessors, and digital interfaces that allow feedback loops run through the plant control room to continually monitor and adjust cryogenic fuel temperature, pressure, and flow rate, cryogenic pump speed, electronic sparking system activation, water temperature and pressure, water pump speed, boiler steam temperature and pressure, boiler material stresses, and the temperature, pressure, and flow rate of the steam turbine intake, while being subject to manual and mechanical back-up systems, safety systems, and control overrides.
