Noise emissions reduction methods for wall gas boilers are here investigated. An intensimetric and vibration measurement campaign has been carried out in order to individuate the suitable noise reduction solutions. Numerical simulations have been led by means of a volume finite code to verify the compatibility between such solutions and the boiler thermofluidodynamic properties. A 3.5dB average acoustic power reduction and a 5.0dB average vibration level reduction have been obtained. A measurement campaign has allowed to verify that the proposed methods do not affect the boiler thermofluidodynamic performances.

Abstract
Noise emissions reduction methods for wall gas boilers are here investigated. An intensimetric and vibration measurement campaign has been carried out in order to individuate the suitable noise reduction solutions. Numerical simulations have been led by means of a volume finite code to verify the compatibility between such solutions and the boiler thermofluidodynamic properties. A 3.5dB average acoustic power reduction and a 5.0dB average vibration level reduction have been obtained. A measurement campaign has allowed to verify that the proposed methods do not affect the boiler thermofluidodynamic performances.File in questo prodotto:
