STEAM TURBINE SERVICES

Macek Power is equipped to handle many aspects of steam turbine design. Capabilities include flow path modeling, performance simulation, and component engineering. Thermal and fluid flow analyses, rotordynamic analysis, and stress analysis are employed as necessary to support design efforts. Components such as blades, nozzles, seals, and bearings can be designed as required for the specified application. Additionally, Macek Power provides design and engineering services for instrumentation, control, lube-oil, and gland leak-off systems.


Project experience includes a wide variety of steam turbine arrangements of various makes and frame sizes ranging in capacity from a few hundred kilowatts to 150 MW. Macek Power engineers have designed complete flow paths for single and multi-stage turbines with either condensing or non-condensing exhausts, and have provided engineering support for turbines with single-flow, double-flow, extraction, and induction arrangements. Significant manufacturing process experience benefits the design process and allows Macek Power to effectively supervise subsequent component manufacturing. 


EXAMPLE WORKS

ROTOR CAD MODEL

The CAD model shown here was obtained by reverse engineering the rotor via light scan methods.  The next step is to use the CAD data to build the performance simulation computer model.

PERFORMANCE SIMULATION MODEL

The rotor geometry shown here represents a multi-dimensional performance simulation computer model.  Less sophisticated methods take a simplified mean-line (one-dimensional) approach.

ROTOR BLADE DESIGN

Both finite element and hand calculation methods are used to evaulate steady and alternating rotor blade stresses as part of the design acceptance process.

OUTAGE TECHNICAL DIRECTION

Macek Power directs a millwright crew for major inspection of a steam turbine employed in electrical power generation service.

FAILURE ANALYSIS

Macek Power is often called upon for root cause failure investigation.

STEAM PATH AUDIT

This image is from a steam path audit of a 55 MW double flow Toshiba brand rotor in geothermal electrical power generation service.

PERFORMANCE SIMULATION I

This screenshot of output from Macek Power developed proprietary simulation software illustrates the performance of an axial turbine Curtis stage.

PERFORMANCE SIMULATION II

This screenshot of output from commercially available simulation software helps illustrate the performance of a multi-stage axial flow turbine.

PRECISION ENGINEERING FOR
SAFE AND RELIABLE TURBINE OPERATION

OUR WORK IS OUR REPUTATION.  OUR GOALS ARE THE SUCCESSFUL COMPLETION OF THE PROJECT ON TIME AND WITHIN BUDGET,

AND MORE IMPORTANTLY, THE CULTIVATION OF A MUTUALLY BENEIFICIAL AND TRUSTING RELATIONSHIP WITH THE CLIENT.
