Cogeneration plant

  1. Nov 23, 2011 #1
    1. The problem statement, all variables and given/known data
    The question asked about a cogeneration plant with water as a working fluid, but I am not sure what type of cycle it belongs to. The plant uses utility heat and steam can be throttled.


    2. Relevant equations
    The system was assumed to be ideal, no pressure drop, no heat loss and is internally reversible.


    3. The attempt at a solution
    Brayton, ideal Rankine cycle?

    I would think it would be the ideal Rankine cycle.

    I believe it's regenerative rankine cycle?

    Yeah that's it, I couldn't remember how the regenerative cycle's T-s diagram looked like. But it should be that one.

    I can leave out the throttling valve in the ts diagram right?since the valve does not give power....but increases pressure?

    I think you mean pump and not throttling valve? But you'd need to have it, else your diagram won't make a cycle.
