<p>The invention relates to an electrically heated catalyst (EHC, 10) and a start-up method of a gas turbine engine employing an EHC (10) in the combustor (33). The catalyst (10) is electrically heated to a predetermined temperature prior to start up of the turbine system and is turned off when any one of several conditions are met, e.g. the heat of catalytic reaction is sufficient to maintain the catalyst (10) in its steady state condition. The EHC (10) is made of stacked or spirally wound foils (12, 14).</p> |
