Abstract: A fuel conditioning system for a turbine plant may include an inlet fuel module followed by a turbine fuel module for each turbine, the modules being monitored and controlled by a programmable logic controller. The inlet fuel module may include a metering station, an inlet pressure control station, an inlet scrubber station, and an inlet coalescing filter station. Each turbine fuel module has a turbine pressure control station, a turbine super-heater station, and a turbine coalescing filter station. The fuel conditioning system may also include a trip transient mitigation system and a latent fuel venting system. The programmable logic controller collects data from all of the stations and systems as well as the turbine and then uses self-correcting algorithms to control the stations and systems. The programmable logic controller also stores the data collected and transmits the data to an off-site storage and verification center.

Abstract: An orifice seal is shown of the type adapted to be inserted into an orifice meter tube for determining fluid velocity within the tube. The orifice seal includes a resilient seal ring which is adapted to be received about a circumferential region of the orifice plate. The seal ring has circumferential grooves formed on either side of an orifice plate channel. The grooves are formed between inner and outer resilient lips of the seal ring. The inner lips of each of the circumferential grooves is arranged to overlie the circumferential region of the orifice plate when the plate is in place to retain the orifice plate within the seal ring. A U-cup spring located within each of the circumferential grooves resists the deformation of the groove lips by pressure acting on the orifice plate to prevent cold flow of the seal material.

Abstract: A device and method are shown for detecting leaks in the differential pressure measuring passageways of an orifice meter tube. A body having a threaded end region is inserted within the differential pressure measuring passageway to be tested. A stem is slidingly received within an internal bore provided in the body when the body is engaged within the passageway. The stem has an exposed end which extends externally from the body and an inner end which is insertable through the internal bore of the body and into the passageway to be tested. A packing cap seals the region of the internal bore adjacent the exposed end of the stem and a deformable seal located on the inner end of the stem is actuated by manipulating the stem exposed end to seal off the opening of the passageway into the orifice meter tube. A test port located on the body communicates with the internal bore of the body for connection of vacuum testing equipment to test the integrity of the passageway.
