STEAM CONTROL APPARATUS FOR TURBINE

摘要

The temperature and flow rate of steam introduced to a gas turbine and a combustor is controlled properly through mixing intermediate-pressure steam and high-pressure steam. Thus, two different requirements; i.e., adjustment of steam temperature and securing of a sufficient steam flow rate, can be satisfied simultaneously. As a result, it becomes possible to simultaneously achieve control of the clearance of the blade ring of the gas turbine by means of steam and cooling of the combustor by means of steam.
