Title:
METHOD AND SYSTEM FOR COOLING HOT GASES BY WATER INJECTION
Document Type and Number:
WIPO Patent Application WO/2010/025739
Kind Code:
A3
Abstract:
Hot gas, produced in a thermal reactor (1), can be cooled in a cylindrical cooling reactor (4) by leading the gas tangentially into the evaporative cooler through and inlet duct (2) whereby the gas perform a rotary movement in the evaporative cooler, and by injection water droplets into the gas at one or more injection zones (3) in such an amount and in such a way that the gas temperature due to water evaporation is reduced to below 400°C. The dry cooled gas can now leave the reactor through the outlet duct (5) and be cleaned for particles in a dry filter (7) and energy can be recovered in a condensing unit (8). Hereby, a compact cooling, cleaning and energy recovery system is obtained, which is cheap and simple and has low maintenance costs, and which moreover has a high efficiency degree and good environmental qualities. The method can be used for a broad spectrum of fuels and conversion technologies.
