Practical Problems associated with Carnot Cycle Plant
- Maximum temperature limitation for cycle (a). What is the maximum temperature in the cycle?
- Isentropic expansion in a turbine from 3-4. What is the quality of the steam inside the turbine? Will high moisture content affect the operation of the turbine?
- Isentropic compression process in a pump from 1-2. Can one design a condenser and transmission line system that precisely control the quality of the vapor in order to achieve an isentropic compression? Even we can, is it practical to handle two-phase flow (liquid + vapor) using such a system?
- The latter two problems can be resolved by the use of cycle (b) from previous slide. However, the (b) cycle requires the compression(1-2)of liquid at a very high pressure (exceeding 22 MPa for a steam, how do I get this number from?) and that is not practical. Also, to maintain a constant temperature above the critical temperature is also difficult since the pressure will have to change continuously.
