Understanding Steam Turbine Technology

Understanding Steam Turbine Technology

Steam turbines are a specific mature technology that has been used since the 1880s. Additionally, steam turbines have been used for the production of electricity. Steam turbine testing continues to evolve as time progresses. Much of the electricity generated in the United States is created by steam turbines that are integrated and utilized in various power plants. With central station power, steam turbines are also generally used for combined power and heat. Let’s examine steam turbines and their many benefits.

Steam Turbine Applications

Based on current data, there are over 600 sites in the country that are utilizing steam turbines for the operation of CHP operation. These particular steam turbine CHP installations have an approximate capacity of 37 MW, coupled with a capacity of 26 GW. With this application representing 32% of the installed CHP capacity in the country, many of these CHP steam turbines are utilized in various paper, chemical, and food industrial plants. These steam turbines are also utilized in various heating sites.

Steam Turbine Performance

In order for a steam turbine-generator to function at an optimum level of thermal performance, the component must be able to sustain thermal performance over a considerable amount of time. Steam turbine testing must be conducted to ensure sustaining thermal performance. Evaluation and assessment of performance requires a three-fold objective. The first helps to detect any deterioration in the steam turbine’s thermal performance. The second helps to detect and ascertain any performance degradation through evolutionary steam turbine testing, evaluations, and measurements. The third is to create cost-effective solutions that help to correct any equipment and operational issues.

Steam Turbine Types And Designs

There are two general kinds of steam turbine designs that are available. The first design is an impulse design that allows the rotor to turn due to the force of the steam that’s on the blades. The second design is a reaction design, that operates on the principle of the rotor deriving rotational force from the steam. The steam will typically enter at one end, then travel in a direction that is toward the other end. Then, the steam will exit the casing and then later travel or reheat and pass to another section. A double-flow steam turbine is different, due to the steam entering the middle and then traveling in both directions. The steam will then travel toward the end of a section. Double-flow arrangements were common many years ago.

Receiving Quality Turbine Support

Whether you have a gas or steam turbine, you need quality support. From comprehensive steam turbine testing, to complete assessments, you need gas turbine support and assistance. Tremendous benefits await with a company that offers unbiased, thorough, and NDE or non-destructive evaluation of steam turbines. You may also need support for your electric generators and combustion turbines. There may also be a need for testing inspections on rotating equipment and visual borescope inspections.
