Abstract: Systems and methods for golf analysis including a tag coupled to a golf club providing statistical analytics for coaching including text, tabular, graphic, and image-based outputs that include trends information for the golfer, all based upon actual golf play on course situations, wherein the golfer inputs shot data during play, without interrupting the flow of the game, and uploads the shot data for analytics and review online, and wherein all information related to a given user are reviewable by an authorized coach user through a web-based coach access account. The system is further operable to provide the coach user rights for providing corrective or instructive feedback to the user, including visual recommendations such as modified target areas.

Abstract: A heat recovery steam generator (“HRSG”) includes a first casing having an interior enclosing at least one duct for gas to flow therein along a gas flow axis. Each duct is defined by duct defining members that are spaced apart from each other and extend into the interior of the first casing. A plurality of stiffening members are elongated along the gas flow axis. Each of the stiffening members are positioned between two of the duct defining members. The stiffening members and duct defining members have a substantially similar coefficient of thermal expansion.

Abstract: Apparatus for handling ash and slag produced in the combustion of coal or other ash-bearing fuel in the furnace (10) (not shown) of a steam generator, including a submerged scraper conveyor (20) beneath the furnace, and a water seal including plate means (24) extending from the furnace bottom or transition chute into the water (18) in the tank (16) housing the scraper conveyor, which plate means (24) also form a seal at their upper ends (40,42) with the furnace bottom or transition chute, for preventing the atmosphere from being exposed to the furnace interior. A motor (50,52) is provided for moving the plate means (24) upwardly and downwardly, to allow the submerged scraper conveyor (20) and its tank (16) to be quickly removed from beneath the furnace (10) when the unit is shut down for maintenance purposes.

Abstract: Apparatus for handling ash and slag produced in the combustion of coal or other ash-bearing fuel in a top-supported furnace (10) of a steam generator, including a submerged scraper conveyor unit (14) beneath the furnace (10), and a water seal (24, 26) including a bottom-supported trough (26) positioned beneath the furnace (10), and plates (24) secured to the furnace bottom extending down into the trough (26). The submerged scraper conveyor unit (14) is bottom-supported independently of the trough (26), and there is an adjustable (34) seal member (29) between the two to prevent gas leakage therebetween.

Abstract: By providing a heat exchanging vessel which employs no moving parts and is interposed in the exit flue between the furnace and the chimney, an efficient energy recovery system is achieved which prevents hot air from escaping without any benefit. In the preferred embodiment, the energy saving system of this invention optimizes normal convection currents and air flow paths to eliminate the necessity for any moving parts or electrically driven equipment, as well as incorporating fin members to increase surface areas for heat transfer and heat radiation.
