Abstract: Certain embodiments may include systems and methods for a protective automobile seat cover system. According to one embodiment of the disclosure, a protective cover assembly for an automobile seat can be provided. The protective cover assembly may include a cover pad for an automobile seat contoured to fit the automobile seat. In an example embodiment of the disclosure, the cover pad may have a top layer, a bottom layer, a top end, and a bottom end. The cover pad may further include an opening for an automobile seat headrest. The assembly may further include a dispenser attached to the automobile seat and configured to store and dispense the cover pad. The dispenser may include a slit configured to allow a user to retrieve and deploy the cover pad. The protective cover assembly may further include an attachment mechanism to attach the dispenser to the automobile seat.

Abstract: A system includes the HRSG having an economizer disposed along a fluid flow path, and a drum disposed along the fluid flow path downstream of the economizer. The HRSG also includes a drum level control module configured to modulate an amount of the fluid provided to the drum along the fluid flow path and a supplemental control module configured to control an amount of the fluid in a different manner than the drum level control module. The heat recovery steam generator also includes a drum level event controller configured to monitor a rate of change of a level of the fluid in the drum. If the rate of change is over a threshold value, a signal goes to the supplemental control. If the rate of change is less than or equal to the threshold value, the signal goes to the drum level control module.

Abstract: The disclosed embodiments relate to a system and method that allows air to be extracted from a plurality of gas turbine engines and fed to a downstream process, even in situations in which one or more of the gas turbine engines are operating in a part load condition. For example, in an embodiment, a method includes monitoring signals representative of a header pressure of a header, or a pressure of extraction air flow from one or more gas turbine engines to the header, or both, and maintaining substantially continuous flows of extraction air from the gas turbine engines to the header. The substantially continuous flows are maintained when the gas turbine engines are under symmetric and asymmetric load conditions.

Abstract: A fuel purging system for a turbine assembly includes a fuel delivery system. The fuel delivery system includes a fuel source for providing a fuel to the turbine assembly, a control valve for regulating a fuel flow of the fuel, a flow divider for selectively distributing the fuel to at least one combustor, and a combustor valve located upstream of the at least one combustor. The fuel purging system also includes a steam source for distributing a steam to the fuel delivery system at a location upstream of the combustor valve.

Abstract: A fuel delivery system for a gas turbine designed to efficiently transfer from one type of fuel to a separate fuel, comprising different and cooperating fuel modules, namely high hydrogen fuel gas, distillate fuel and naphtha fuel modules, each of which feeds a different liquid or gas fuel to the combustors, an atomized air delivery system for either the naphtha or distillate (or combinations thereof), an air extraction system, a plurality of distribution control valves for the high hydrogen fuel gas, distillate fuel and naphtha fuel modules, and a nitrogen purge system to purge the high hydrogen fuel gas lines to the combustors and/or flushing the naphtha lines with distillate.

Abstract: A system includes a heat recovery steam generator (HRSG), a waste heat exchanger coupled to the HRSG and configured to transfer heat from the HRSG to a purge stream to generate a heated purge stream, and a heated purge stream path configured to transfer the heated purge stream from the waste heat exchanger to an inlet of the HRSG.
