Gas turbines are essential to power generation. They are mainly used for large-scale electricity generation. There are two types of land-based gas turbines: aero-derivative engines and heavy frame engines. Heavy frame engines are typically very large and have low-pressure ratios. Aeroderivative engines, on the other hand, are typically smaller and have high-pressure ratios.
Land-based gas turbines usually do strenuous work to produce electricity, and they operate at extremely high temperatures. As a result, they are prone to breakdown. Turbine breakdown can lead to lost time and money for a power generation plant. Thus, it is important to inspect turbines to ensure they are operating optimally. Generator inspections allow technicians to examine the exterior of the turbines up close and detect any defects.
Turbines are often inspected using borescopes. A borescope is an instrument used for visual inspection. Borescopes are advantageous because they can inspect hard-to-reach areas that can’t be reached by inspected by technicians. Borescope inspections are great for the following situations.
During pre-commissioning, gas turbines are examined to ensure they are functioning well before commissioning. Borescope inspection can ensure any underlying issues that would otherwise go undetected are spotted before commissioning.
2. Outage Planning
Outage planning is aimed at ensuring that unintended maintenance activities are avoided during an overhaul. When done appropriately, maintenance shutdowns can significantly reduce costs.
3. Baseline Inspection
Power plants usually undergo baseline inspection. Baseline inspection prioritizes activities that are not closely measured by performance indicators.
4. Condition Based Maintenance
Condition-based maintenance (CBM) focuses on monitoring the condition of turbines to determine what maintenance needs to be carried out. CBM emphasizes that maintenance should only be done when there are specific signs of a decline in performance or potential malfunction. CBM aims to monitor and detect potential equipment malfunction, so maintenance can only be scheduled when necessary. CBM can reduce the cost of equipment failure and reduce the time spent on maintenance. Additionally, it can bolster worker safety. Borescopes are key to successful condition-based maintenance.
Why You Should Hire Professionals for Borescope Inspection of Gas Turbines
Borescope inspection isn’t straightforward. It requires expertise. It isn’t a labor-intensive process, but a gas turbine inspection using a borescope requires technical know-how. An expert can detect underlying issues that would otherwise go undetected if examined by a non-professional. Additionally, experts are more likely to know where to examine the gas turbines when performing a borescope inspection. Overall, you are likely to save plenty of money and time if you choose to use a professional borescope inspection service.
Why Gas Turbine Inspections Are Essential
Gas turbines are almost unparalleled when it comes to electricity generation. They’re compact, fairly silent, easy to install, efficient, and they can run without water cooling. Above all, they’re incredibly durable. However, because they operate at extreme temperatures, they’re susceptible to wear and tear. If gas turbines malfunction, the operations of an entire power plant can come to a standstill.
That’s why regular maintenance checks are crucial. Inspecting turbines regularly can ensure they operate at their optimum levels and avert breakdowns. Don’t leave turbine inspection to a novice. Hire a turbine inspection service and save time and money.
