Abstract
A method is provided for atomizing fuel in a turbine engine having a compressor, turbine, recuperator, and combustor. The steps include flowing a compressed air to the combustor and passing a fuel to the combustor. A compressed air pressure from the compressor is sensed, as well as sensing a first pressure of an assist air. The first pressure is compared to the compressed air pressure. Then, the first pressure is adjusted to a desired pressure that is a function of at least one of the operating parameters such as turbine speed and the compressed air pressure. The assist air at the desired pressure is next moved to the combustor.
