Method and apparatus for utilizing alpha decay radiation energy in electric power generating system

Abstract

The present invention relates to a method and apparatus for utilizing radiation energy by alpha decay in electric power generating system. The present invention implements a power generation system in which an improved efficiency of fuel combustion and effective purification of exhaust gas can be attained with the use of radiation energies caused by alpha-decay of a natural radioactive element. In particular, according to the invention, a fuel activating device, a feed air activating device and a neutron energy irradiating device are provided, wherein a feed fuel and an intake air being necessary for combustion in a combustion device in the electric power generating system are irradiated with a radiation by alpha of a natural radioactive element irradiating 0.6 becquerel or more of alpha ray and with the neutron generated at the same time, to thereby convert the oxygen in the intake air to an active oxygen and achieve complete combustion of the feed fuel with the resulting intake air; the above apparatus which further has a feed water activating device with an aerator for the feed water to a steam generator and an exhaust gas clarifying device with an aerator for the exhaust gas from the combustion device.

Problems solved by technology

[0004] In addition, the combined cycle power generation system of a high-efficiency large-scale gas turbine using liquefied natural gas (LNG) and a steam turbine that recovers the high-temperature exhaust heat of the gas turbine burns clean natural gas, so the comprehensive power generation efficiency reaches about 50%, and the gas emitted is also clean, but the CO it emits 2 and NO x the amount is huge

[0005] In a conventional power generation system, as a method of purifying exhaust gas or improving combustion, it is generally achieved by combining various methods and making them larger. However, in the use of LNG, due to the availability of LNG Due to the restrictions of region or LNG consumption, etc., it is not suitable for small and medium-capacity power generation systems, and NO x and CO 2 more discharge

Recently, with the technological advancement of micro gas turbines, a power generation system that uses LNG as fuel to generate electricity and uses exhaust gas recovery boilers to control the temperature of residential quarters has been developed, but it is not enough as a countermeasure to prevent environmental pollution by exhaust gas
