<p>METHOD OF STARTING A COMBUSTION SYSTEM UTILIZING A CATALYST A method and system are provided for starting a combustion system utilizing a catalyst, and at the same time provide low emissions of unburned hydrocarbons and carbon monoxide. The method is particularly applicable to starting such combustion systems which are subject to intermittent operation, such as for example, gas turbines used to power automotive vehicles in which carbonaceous fuels are combusted to provide the motive fluid, or furnaces which are used intermittently. In the method, heat, such as produced by electrical means or by thermal combustion of a carbonaceous fuel, is employed to bring the catalyst to an operating temperature which will permit rapid oxidation of the carbonaceous fuel. When the catalyst has been heated to reach such operating temperatures, the start-up heating may be terminated and the normal operation of the combustion zone including the catalyst may proceed.</p> |
