WHY CHOOSE US

Why use our NIRAEUS® Acoustic System?

The answer is simple: saving money while preserving the environment!

It is economical because it uses only compressed air from the network at 6 bar, it is compact, non-invasive, simple and its periodic maintenance is done on-line. It does not cause damage or even unforeseen shutdowns of the plants.
It preserves the environment because the steam produced becomes Energy and is not used for cleaning, so with the same amount of energy produced (steam generation), the plant saves many tons of fuel (coal, biomass, waste, etc.).

The Technology of Acoustic Cleaning

Acoustic Cleaning Technology, to prevent the accumulation of ash, soot, particulates and dust.

The accumulation of ash, soot and particulate matter have always been problems associated with boilers. This adds to the flow issues, such as soot aggregations in general, particulate bridges, funnels and dusty obstructions, which are created in industrial processes around the world.

While industry has been addressing this particular problem for the past 40-50 years with steam soot blowers and other “flow enhancing” devices such as pulse compressed air blowers, mechanical actuators on hoppers, hammers, all of these are not sufficient to provide a balanced solution in terms of investment, cost-effectiveness, performance, efficiency and operation, as well as maintenance.

Our Acoustic Units (also known as sonic horns, acoustic cleaners, acoustic blowers, horns) operate with Audio-sonic frequencies (between 60 and 300 Hz), therefore frequencies that are not as harmful and not dangerous as those generated by conceptually similar systems but that use Infrasound, which are very dangerous for structures and equipment, because they emit very low frequencies, which create destructive resonances.

The frequent case

Do we want to analyse together one of the most common traditional systems?

Let’s therefore consider it as one of the most common traditional and conventional systems already installed on the plant: Steam sootblowers.

If we produce steam to produce energy, why waste it to remove dust and/or ash?

Steam blowing (a very frequent case with blowers installed some time ago) causes erosion and corrosion effects on the exchange surfaces, to the point of causing breakage and plant stoppage, with loss of production.

Spare parts are expensive and for their replacement the plants must be stopped, with loss of production.

The blowing action radius are reduced and act only where the steam jet impacts the surface.

And if instead we consider a new plant, in addition to the points mentioned above:

Experience and competence!

GMF provides customized acoustic cleaning systems for industries around the world from over 10 years. Our Technicians have over 20 years of experience in keeping processes clean in various types of applications, from boilers to filters, heat exchangers, SCR, etc., with a background of more than 40 years of experience in the Energy sector.

Acoustics Technology

NIRAEUS® Acoustic Cleaning Systems by GMF, provide the most energy-efficient solution for removing ash and soot. A small amount of compressed network air and continuous operation with 3-4 sound cycles per hour, are sufficient to maintain high process efficiency. The energy savings are considerable, especially for thermal power plants.

No erosion, no corrosion, no water or mechanical wear!

NIRAEUS® systems drastically reduce the use of water in power plants. Steam is no longer needed to blow soot, so it can be used for its original purpose in Power Generation.

GMF is a member of industrial associations that deal with sustainable technologies in the energy/environmental field.

Solutions tailored to the needs of each Customer!

The NIRAEUS® Acoustic Cleaning System is a combination of Acoustic Units, selected from time to time for each project and application. The system removes particles from surfaces by means of sound pressure (in fact, sound is a product of the vibration of a body, generated by pressure variations). The pulses or sequences of sounds are repeated until the result required for cleaning is achieved.

Constant level of cleanliness at all times!

The Acoustic System usually includes a Control Panel for programmed sequence control. The desired level of cleanliness is kept constant during the production program, so that the removal process remains adequate and efficient without interruption.

Target: costs reduction!

Hundreds of systems already benefit from NIRAEUS® Acoustic Cleaning Systems. Cost savings are the result of improved operating efficiency, no production losses, no unwanted downtime, reduced operating and maintenance costs, fuel savings.

THINK EFFICENT.
