A combustor (130) for a gas turbine system (100) includes an additively manufactured (AM) one-piece member (164) with a combustion liner (166) with a transition portion (170) and an aft frame (190) at an aft end (232) of the transition portion (170). An impingement cooling structure of the transition portion (170) includes impingement openings (254) leading to an internal impingement cavity (256). A coolant passage (260) extends from the internal impingement cavity (256) to the aft end (232) of the transition portion (170). A coolant passage (260) outlet is near an aft rail (266) extending radially inward from the transition portion (170) aft end (232) and axially spaced from the aft frame (190). In operation, coolant enters the internal impingement cavity (256) through the impingement openings (254), then travels through the coolant passage (260) to cool the aft rail (266). The AM combustor body (160) includes a plurality of parallel, metallurgically bonded metal layers (280). The impingement cooling structure promotes increased cooling to the aft frame (190) and combustion liner (166) without loss of structural strength.

A shortened piping layout for a steam cycle circuit (352) of a combined-cycle power plant (354) without thermal expansion loops is provided. The piping layout includes a first steam pipe (366) to provide a first supply of main steam from a steam generating source (356) to a first turbine section (126, 226) of a steam turbine system (358). A first steam admission valve (361) is configured to receive the first supply of main steam at a bottom portion. A cold reheat steam pipe (368) supplies cold reheat steam exhausted from the first turbine section to the steam generating source for reheating. A hot reheat steam pipe (370) supplies hot reheat steam from the steam generating source to a second turbine section. At least one reheat steam admission valve (363) is configured to receive the hot reheat steam at a side portion for introduction to a side portion of the second turbine section.

The invention refers to a wireless power transmission system (10) and method. It comprises a power transmitter arrangement (11) and a power receiver arrangement (12). The power transmitter arrangement (11) is configured to transmit electromagnetic wave pulses (W) to the power receiver arrangement (12), where the electrical energy can be accumulated and/or stored. The power receiver arrangement (12) is configured to create a feedback signal (F) for controlling the amount of transmitted electrical energy and/or power. The feedback signal (F) is wirelessly transmitted from the power receiver arrangement (12) to the power transmitter arrangement (11). In the power transmitter arrangement (11) the creation of electric pulses (P) resulting in the transmission of electromagnetic wave pulses (W) is controlled based on the received feedback signal (F).
