Finding new methods for saving energy is a global megatrend. Implementing technology that saves energy will have a positive impact on sustainability. Gas turbines are widely used for energy production as natural gas is one of the cleanest burning fuels. One of the most important parts in a gas turbine is the blade section, which converts the kinetic energy of the hot combusted gases into electric power with the help of a generator connected through a rotating shaft.
However challenging the weather conditions may be, the air entering the system must be as clean as possible. Despite humidity, salt, soot, dust or sand, the air before combustion must remain clean for maximum efficiency in burning the gas. In the power generation industry there is therefore a trend towards higher efficiency media, because contamination reaching the turbine blades will have a negative impact on the throughput of the gas turbine power plant.
While the function of air intake filters is to separate the contaminants, they also form a barrier to the air entering a gas turbine. This means that the filters generate a pressure drop which requires a lot of energy to pump the air pass through the filters. The second generation of gas turbine air intake filter media simultaneously meets energy savings criteria and particle removal requirements. New Trinitex® air intake filter media are designed to minimize the pressure drop, and consequently the energy consumption to feed the gas turbine, maintaining or increasing filtration efficiency to safeguard that the blades remain clean and the power plant runs at maximum efficiency.
A 50 Pa pressure drop increase over the air intake filters can easily reduce power plant output by 0.1-0.5%. Power plant studies have moreover revealed that output degradation due to fouling is in the order of 1.5% per month, varying to some degree based on geographical location. Gas turbine air intake media such as Trinitex® therefore offer tremendous opportunities for cost savings in the thousands or even millions of EUROs, depending on the size of power plant operations.
At the same time, lower gas consumption means lower environmental impact, by reducing CO2 emissions at the exhaust.
