We had a host to whom we use to provide steam and the host is down now. Boilers were originally sized according to the load conditions but after the host is gone, they are too big for what we need the steam for.
We are not looking at this from the efficiency stand point; reason being, we need this boiler to start the combined cycle operation and shut down after the combined cycle is up and self sustaining. So for every start of the combined cycle, this boiler has to be running for a maximum of 4 hours...
Thanks for the reply.
We are also looking into purchasing the smaller once through boiler and looking at the cost Vs converting the existing boiler to run at lower MCR.
Hi,
