Document Type and Number:
Japanese Patent JP2017036693
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a steam turbine plant capable of simplifying a structure and reducing cost while improving heat exchange efficiency and improving performance.SOLUTION: A steam turbine plant comprises: a high-to-intermediate pressure turbine 21 including a high pressure turbine part provided in one end portion in an axial direction C and an intermediate pressure turbine part provided in the other end portion; low pressure turbines 22 and 23 disposed to be coaxial with the high-to-intermediate pressure turbine 21; a pair of low-pressure moisture separator/heaters 28a and 28b disposed on both sides of the high-to-intermediate pressure turbine 21, removing moisture from steam from the high-to-intermediate pressure turbine 21, and feeding the moisture to the low pressure turbines 22 and 23; and a pair of fourth low-pressure feedwater heaters 46a and 46b disposed on both sides of the high-to-intermediate pressure turbine 21 and heating condensate water (feedwater) by the steam from the high-to-intermediate pressure turbine 21.SELECTED DRAWING: Figure 3
