초록 ▼

A method for operating an energy system includes calculating an auto-ignition temperature of a fuel in use with the energy system, storing the auto-ignition temperature in a system memory, unloading a gas turbine associated with the energy system to a pre-determined range of operations, controlling a temperature of the exhaust flow discharged from the gas turbine, opening an exhaust bypass damper to a pre-determined position to enable a pre-determined volume of air to enter an exhaust flow path defined within the energy system, and releasing the energy system for normal operation after a pre-determined amount of time has elapsed.

대표청구항 ▼

What is claimed is: 1. A method for operating an energy system, said method comprising:calculating an auto-ignition temperature of a fuel in use with the energy system;storing the auto-ignition temperature in a system memory;unloading a gas turbine associated with the energy system to a pre-determined range of operations;controlling a temperature of an exhaust flow discharged from the gas turbine to the energy system;opening an exhaust bypass damper to a pre-determined position based on a comparison between the temperature of the gas turbine exhaust and the auto-ignition temperature of the fuel in use such that the gas turbine exhaust bypassed the energy system to enable a pre-determined volume of air to enter an exhaust flow path defined within the energy system; andreleasing the energy system for normal operation after a pre-determined amount of time has elapsed.
