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.
