are responsible for powering all kinds of things around the world.
You have almost certainly benefited from them numerous times, probably without consciously acknowledging it. But what exactly are gas turbines? How do they work and how can you keep them running efficiently?
Here’s a quick guide telling you everything you need to know about these amazing systems…
A gas turbine is used to power various things including aircraft; trains; ships; pumps; gas compressors; tanks; and electrical generators to power e.g. homes.
What are the 3 main components of a gas turbine?
The compressor has rows of rotating and stationary blades. The rotating blades accelerate the air in both the axial and circumferential directions, while the stationary blades ensure the flow of air is redirected and prepared for the next set of rotating blades.
Working together, the series of blades create a continuous flow of increasingly compressed gas.
Although all used for a similar purpose, there are different kinds of gas turbine compressors:
ISO stands for International Organisation for Standardization and the ISO conditions for gas turbines are 59ºF, 14.7 pounds per square inch absolute, and 60% relative humidity.
It is important to compress the air before ignition as this allows for greater expansion and a more complete, efficient combustion.
As the name suggests, steam turbines are rotated using steam. There is no compressor or combustion system in this process. Water is heated in a boiler, offering the opportunity to use a renewable energy source.
Although natural gas is the most common fuel for gas turbine plants they can be adapted to use almost any flammable gas or light distillate petroleum products e.g. petrol, diesel, or paraffin.
Crude oil and other heavy oils can even be used if they are first heated to reduce viscosity.
Efficiency is important to your operations but it can be difficult to know if your turbine is running efficiently or not. Use our tool to determine if your system could use some improvements.
As air and fuel flow through the compressor, are inevitably deposited on compressor blades.
When these foulants build up they interrupt airflow and compromise efficiency.
If you are noticing inefficiency in your system it is worth looking at your compressor cleaning schedule.
A simple, method of is to regularly cleanse away foulants from the gas turbine compressor.
The hardware to complete cleans even during normal turbine operation can be retrofitted in almost every case.
Rochem are specialists in cleaning technology for gas turbine compressors.
Our range of is specifically designed to take on the .
We also design and supply hardware which can usually be retrofitted.
Atomised water and detergent (if desired) is sprayed directly into the compressor, effectively removing foulants and restoring a clean, efficient and productive system.
