Gas turbines are a mode of production of electric power, privileged over others for variables reasons depending on the case, including sometimes the fact that it involves power stations of which footprint is moderate (when compared to the footprint of coal-fired plants or of nuclear power stations), which can be therefore a priori implanted almost everywhere and whose location can be notably guided by the proximity of consumers (e.g. in industrial zones when it is not in a semi-urban environment) or by the proximity of fuel deposits (e.g. gas, crude oil).
The fight against noise pollution that they may generate is not the only field of intervention of ITS which is also marketing technologies and services for solving problems related to those of industrial soundproofing.
Indeed, these plants with very variable production capacity (from a few MW for the smallest ones to several hundred MW for the largest ones) are based on the use of machines affiliated to internal combustion engines requiring combustion air and a fluid for its (complex) forced ventilation systems sufficiently clean.
In case of plants which are sometimes located in places as hostile as a desert where recurring sandstorms occur, specific devices must be envisaged in order to allow the proper functioning and durability of the various high-tech equipment involved by the various operating principles used.
ITS will participate in the construction of filtration systems for two high-power gas turbines (more than 120 MW single cycle, more than 190 MW combined cycle) for a power plant in North Africa.
The quality of the air once filtered will obviously constitute a major criterion of judgment of the quality of these systems, the modalities of their maintenance (e.g. the replacement of the consumables) also constituting an essential aspect of this filtration system for gas turbines.
As often happens for installations upgrading projects providing the implementation a posteriori of equipment not originally planned, the design of devices which are both efficient and compatible with the existing equipment e.g. sufficiently compact to enable their addition in a gas turbine environment where little space is available for them will be a major challenge.
As always in regard to filtration systems for gas turbines, the choice of optimum filter media and their integration in a sophisticated system whose piloting requires specific instrumentation will be key factors for success.
The design and the construction of a gas turbine filtration system requires multidisciplinary technical skills, all of which must be of the highest standard, the performance of the related technology and its durability not being the least of quality of equipment marketed by ITS, which can be sollicited for any project in relation to air intake systems.
