Dow has charted a strategic path to unify process automation across its global operations, demonstrating how a single DCS ...

Turbine run-up speed control (auto and manual) ... Exhaust steam pressure control. The turbine is unloaded in proportion to rising exhaust steam pressure until a preset minimum load is achieved.

The steam turbine’s original five-pad ... for high-precision control of ... significant subsynchronous vibrations and enabled full-speed, full-power operation of the turbine. 3.

The turbine power plant has about 500 I/Os. The new standalone control system—separate from the plant’s distributed control system (DCS)—communicates with a Delphi vibration monitoring system. A key ...

Steam at a pressure of 200 pounds is supplied to a Westinghouse Parsons turbine for each shaft, each turbine developing about 3,600 shaft horse-power on 1,220 revolutions.

THE history of the steam turbine previous to the reign of Parsons, whose first patents were applied for in 1884, may be made out from chapters i. and ii. But descriptions of inventions in the ...

Designed for commercial, industrial, institutional, and municipal applications, the system is easily installed in a building's high-pressure steam distribution system in parallel with existing ...

The use of longer steam turbine last-stage blades (LSBs) reduces the number of low-pressure casings and, thus, a turbine's total installed cost. In many cases longer blades extract more energy ...
