The Greatest Economy in a Regenerative Feed Heating Cycle

In a regenerative feed heating cycle, the greatest economy is obtained when steam is extracted from several places in different stages of steam turbines. Let's understand why this is the case by analyzing each option given in the question.

a) Steam is extracted from only one suitable point of a steam turbine:
- Extracting steam from only one suitable point in a steam turbine limits the amount of heat energy that can be utilized.
- Since the extraction is done from a single point, the remaining steam is not fully utilized, resulting in reduced efficiency and economy.

b) Steam is extracted only from the last stage of a steam turbine:
- Extracting steam only from the last stage of a steam turbine allows for some heat energy to be utilized, but it is not the most efficient option.
- The steam extracted at the last stage may still have a significant amount of energy that could be further utilized in earlier stages, resulting in a waste of potential energy and reduced economy.

c) Steam is extracted only from the first stage of a steam turbine:
- Extracting steam only from the first stage of a steam turbine also limits the utilization of heat energy.
- Since the extraction is done at the beginning of the turbine, the remaining steam passes through the subsequent stages without fully utilizing its energy potential, leading to lower efficiency and economy.

d) Steam is extracted from several places in different stages of steam turbines:
- This option offers the greatest economy in a regenerative feed heating cycle.
- By extracting steam from multiple stages of the turbine, the heat energy is effectively utilized at different points in the cycle.
- The extracted steam can be used for various purposes such as feedwater heating, auxiliary processes, or other power generation applications.
- This maximizes the utilization of heat energy and improves the overall efficiency and economy of the system.

In conclusion, extracting steam from several places in different stages of steam turbines provides the greatest economy in a regenerative feed heating cycle. It allows for the efficient utilization of heat energy, resulting in improved system performance and overall cost-effectiveness.
