Document Type and Number:
WIPO Patent Application WO/2020/179939
Kind Code:
A1
Abstract:
The present invention relates to a technology regarding a steam injector for an exhaust heat recovery boiler of a hybrid thermal power plant. The steam injector comprises: a steam injection tube configured such that steam is introduced through one end thereof and is then discharged through the other end thereof; multiple nozzles formed on the other end surface so as to constitute a circle; a porous plate provided inside the steam injection tube; a mixed injection tube having multiple mixing nozzles formed such that rear-end parts thereof are connected by multiple coupling points while surrounding the outer surface of the other end of the steam injection tube, thereby forming a channel through which the water flows, and the front ends thereof surround the nozzles, the mixing nozzles having an inner diameter larger than the outer diameter of the nozzles; a mixer module comprising an arm disposed in front of the mixed injection tube so as to engage with the outer surface of the mixed injection tube, a shaft extending towards the interior of the mixing nozzles, and a propeller connected to an end of the shaft. Steam and water are mixed in the mixing nozzles and then injected.
