Therefore, as shown in figure 15, also can consider the first middle-pressure turbine 112 to be further divided into 1-2 middle-pressure turbine 113, but can produce following problem in this case, because of the increase of casing quantity, follow the building in this, the increase of pipe arrangement to cause the manufacture cost of equipment to increase.And, also produce following problem, because increasing, the number of axle (quantity of divided turbo machine) cause vibrative possibility to increase.
In addition, also can consider not use Ni base alloy and adopt ferrite material to deal with, but in this case, need in casing, import a large amount of cooled vapor, causing turbine interior Efficiency Decreasing.
