The reaction – type has all the advantages of the impulse- type, plus a slower operating speed and greater The steam is fed from a high- pressure line into the high pressure turbine through a valve. After passing through this high pressure turbine where some of its energy is to useful work, the steam is fed to a low pressure turbine. The larger the diameter of the low pressure turbine is due to the increased of steam as it because of the decrease in pressure. The low pressure turbine usually consists of a of impulse and reaction elements. All of the stages of the low pressure turbine operate on the reaction . This rotor also carries the blading of the element which is used for backing down. The turbine bearings special attention. They support the weight of the rotor and are to maintain a close clearance between the stationary and rotating blades.
