electricity production unit it should of course be understood that there may be a plurality of such gas turbines in any suitable arrangement with one another such a turbine system is thereby adapted to produce the desired amount of peak load power it will be apparent to those skilled in the art that the gas turbine power units and their accompanying electric and steam generators can and will vary in both number and size depending upon the particular capacity of the system desired it should also be understood that more than one coal gasifier may be used in the process cycle to convert the necessary amount of coal feedstock to satisfy both peak and base load requirements it is also a part of the invention that any excess or waste heat may be either recovered from or exchanged between various conduits or units as best benefits energy requirements for example sensible heat recovered from the coal gasifier can be used as a steam source for any of the steam turbine electricity producing units an additional variation of the process can be provided by a second source of peak load power which can be supplied through the combustion of any net liquid methanol product in a gas turbine the heat in the exhaust gases from the turbine generator is preferably recovered in a suitable steam generator and a clean stack gas released to the environment it is to be noted that it is within the scope of this invention to incorporate any suitable combustion arrangement having an alkyl alcohol as a fuel for.
