1. Steam Turbine Operation Manual

Video using Steam Turbine Training and Governing System Training software. The primary focus on graphics/animations in the steam turbine training course, helps to very clearly understand steam turbine/governor maintenance procedures & steam turbine operating/working principle like turbine/governor control, governor hunt, turbine/governor droop, turbine/governor trip mechanism, etc.

It also aids in turbine repair. The steam turbine training program provides detailed knowledge on steam turbine assembly and dismantling. Animated cut-sections give a deep insight into steam turbine operation and how they work.

Steam Turbine Operation Manual

The N600-16.7/538/538/-3 steam turbine used in this project is a subcritical, single reheat, condensing, tandem, three-cylinder four-exhaust, impulse steam turbine produced and designed by Dongfang Steam Turbine Works. The main and reheat steam of it is configured to unit system in form of two-one-two.

Its high pressure (HP) cylinder contains one single-governing stage and eight-pressure stage; the intermediate pressure (IP) cylinder has five-pressure stage; the high and intermediate pressure (HIP) flow passages are designed to two-layer countercurrent with a common casing; and the low pressure (LP) is two-layer double-flow LP cylinder with 2.2.7 pressure stages. Through four pieces of admission pipe that are vertically and symmetrically arranged at the middle of the HIP outer casing, the main steam enters into the steam turbine, and then to the boiler reheater after experiencing HP 9-stage work. Similarly, the reheat steam enters into the IP part of the steam turbine in the same way as the main steam, and then enters into two LP two-pass cylinders separately through a piece of reducing connector after IP five-stage work; at last it is exhausted into a double-back pressure condenser through the bi-directionally arranged exhaust pipe of the two cylinders after the 7-stage work. The steam turbine is equipped with two HP main stop valves that are used for contacting the sealing surface well so as to prevent steam leak at the status of wide open. There are steam strainers inside the valves for purpose of preventing foreign substances from flowing into the flow passage. The unit is provided with four main steam control valves for regulating steam volume entering the steam turbine.

They are equipped with a balance chamber for preventing from vibrating and arranged into a shared valve casing in the form of straight line. The valve casing is independent of the steam turbine proper. The IP main steam valves and control valves are union valves with a common valve seat, wherein the former two are sleeve valves and the later four are spherical valves. Both of them are able to move independently during the total stroke, and opened, closed by hydraulic pressure and spring separately. T he unit is also provided with two IP union valves each of which has a steam strainer for preventing foreign substances from entering the flow passage. Under normal condition, the IP main stop valves and control valves are widely open.

The main stop valves, control valves and union valves are equipped with on-off testers solely used.
