Reduction of the exposure to noise emitted by a single-facer corrugator

A single-facer corrugator is a machine allowing the production of single-sided corrugated cardboard from a web of paper which is formed between two cannulated cylinders, which are heated with saturated steam, and from glue, applied by the means of a cylinder in rotation.

This process is accompanied by significant noise emissions, likely to induce the exposure of workers to the risks due to noise, which is regulated by the Decree n ° 2006-892 of July 19, 2006 relative to the prescriptions of...

Soundproofing of a Heating Ventilation and Air-Conditioning (HVAC) System

Thermal comfort and air renewal are fundamental features for a building (whether residential, tertiary or industrial) requiring a Heating Ventilation and Air-Conditioning (HVAC) installation often involving air flows that are often rejected outside, and therefore, if they themselves constitute a source of flow noise e.g. because of excessive fluid speeds or if they allow the propagation of noise of upstream components, may be in able to negatively impact the sound environment, especially in the...

Biogas methanation-cogeneration without noise pollution (ITS at Expobiogaz 2018 Strasbourg-France)

At a time when renewable energies are of particular interest, methanation (i.e. degradation by micro-organisms of waste/organic material under controlled conditions, especially in the absence of oxygen) is a popular process (since the resulting biogas can be used as fuel for a heat engine).

The combustion of biogas can enable the production of electrical energy and the recovery of heat (cogeneration): this constitutes a mode of valuation currently quite widespread, which leads to the...
