Question

Which answer best describes the process that takes place in an open feedwater heater for a regenerative rankine cycle?

Question 1 options:

Warm, wet steam is mixed with cool liquid water to raise the temperature of the resulting liquid mixture.

Saturated liquid water is raised in pressure to a compressed liquid state.

High pressure hot water is throttled down to a lower pressure, causing the liquid to flash to the vapor phase.

Warm, wet steam releases heat through a physical barrier into a flow of cool liquid water to raise the temperature of the liquid.

Explanation / Answer

In open feed water heater, the warm and wet steam is mixed with liquid water from pump to raise the resultant mixture temperature. Here, the steam mixes with water directly.

Hence, the correct option is (a).
