    Westinghouse 501DA Fuel Conversion

    The 501Ds are good machines with a reasonable base load. They were the first Dry Low NOx machines. I don't know if Siemens is converting them to TXP (Siemens control system)or not. If your customer is serious the first step is to look into a control system - WDPF(spares) or after market. Should...
