Dear All,
We manage 2 block of gas turbine 3x100 MW dan steam turbine 180 MW. We have a policy to reduce the consumption of oil fuel in our power plant. One of these policies is to change fuel in power plant from HSD to MFO (Marine Fuel Oil) or residual fuel. So our power plant will be the pilot project to conduct that.
Beside of the hardware installation of MFO (including pre-oil treatment and its waste), we understand that some rung of our Mark V control system should be changed too. Result of our study comparation in the other power plant told that MFO using in GT after loaded 30 MW. So during start up we should use HSD. (It happened during shutdown process too, before zero RPM must be transfer to HSD). But unfortunately, they do not use same Turbine Control (Mark V).
Our questions are:
1. Is the re-design for Mark V (adding rung) only for rung start up and shutdown process that there is transfer fuel from HSD to MFO and its opposite?
2. How the percentage of process transfer from HSD to MFO (and MFO to HSD) is direct, or must there be a hold at some procentage first, and how does the transfer effect our running GT?
3. If we are using MFO as the fuel at GT, is the setting of Turbine protection at Mark V changing or still the same as distillate fuel (HSD)?
We wait for your kindly response.
Thanks,
Aiko
