  • Fuel cleaning for gas fired engines
    Patent number: 8435329
    Abstract: Gas fired internal combustion engines which are run on contaminated fuel suffer from the buildup of internal deposits and corrosion. This is a particular problem with engines fuelled by biogas, e.g. from waste decomposition. By filtering the fuel via a filter containing an ion-exchange resin substantial improvements can be obtained.
