Title:
THERMAL POWER GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/104023
Kind Code:
A1
Abstract:
The present invention provides a thermal power generation system which is highly efficient and highly economical even when the site conditions are such that water cannot be obtained from an ocean or a large river in the vicinity of the power generation plant, and when it is not possible to be supplied with water for industrial use from outside the plant. This thermal power generation system is characterized by being equipped with water recovery equipment (5) that recovers moisture by condensing steam in the exhaust gas from a boiler (1), water purification equipment (6) that removes particulate matter and toxic substances from the recovered water and adjusts the pH, a retention pond (7) that stores the purified water, and an air-cooling type cooling tower (10) to which water from the retention pond (7) is supplied, with the water recovery equipment (5) and the air-cooling type cooling tower (10) forming a closed-circulation water cooling system. By means of the present invention it is possible to achieve a highly efficient and highly economical power generation plant which satisfies various types of demands for water in the plant by recovering and storing water from the exhaust gas from the fuel used to generate power, even when there are significant restrictions on the use of water resources at the site where the power generation plant is erected.
