9. The temperature limit of austenite stainless steel is less than 700℃

10. Only heat-resisting steel can be adopted for use

Passage 6 The role of the condenser

1. A condenser is a heat exchanger removing the vaporization heat from the exhaust steam and condensing

the exhaust steam into water

2. It is suggested that the water should not be cooled below the saturation temperature3. The saturation temperature would not remove excess energy from the system and reduce the overall

efficiency

4. It is unnecessary to reduce the steam to water so that it can be pumped back through the system

5. The condenser does not control back-pressure at the turbine exhaust6. The important factor controlling the turbine backpressure is the temperature of the cooling water

passing through the condenser tubes7. The temperature of cooling water will increase its temperature between 15oF and 20oF as it passes

through the condenser.8. The terminal difference means the temperature difference between the cooling water and the turbine

exhaust steam

9. The temperature increase of the cooling water and the terminal difference depend on 3 factors.10. The exhaust steam temperature does not rely on the temperature of the cooling water which enters the

condenserPassage 7 Hydraulic structure

3. The equipment installed inside the dam is to discover the normality of dam in time.

4. Horizontal displacement is more important than vertical displacement

5. Temperature stress and strain are the two main monitoring items of dam

6. The monitoring method is the suitable points on the dam and its foundation.

7. Some monitoring devices are movable for periodical supervision.)

8. The monitoring result result shall be analyzed and studied by computers.

Passage 8 Heat treatment

1. The post-weld heat treatments have two main purposes

2. One of the purposes is to diminish the residual stress in the welded joints.

3. The other purpose is to improve the organization of the welded joints

4. The welding crack can be classified into 5 categories

5. To change the internal structure of the work piece is one of purposes for heat treatment

6. There are 5 kinds of steel heat treatment

7. The processes of heat treatment include 4 procedures.

8. The electric resistance furnace is not widely used9. Heat treatment furnaces are not composed of electric resistance furnace, combustion furnace and surface
