The invention relates to a method for determining the instantaneous rate of the mass flow of a flow of a fluid pulsating periodically at a frequency f, said method comprising the following steps: a) a pressure gradient in the flow over a certain period (P) is determined, b) the harmonic amplitude of the pressure gradient is calculated by means of Fourier transformation, c) the frequency f and the time t are converted into dimensionless numbers F, t and d) the rate of the mass flow is determined using a table from which at least one corresponding value describing the mass flow rate and/or a phase difference can be deduced for each dimensionless number F of the frequency f.

Method and device for determining the instantaneous mass flow of pulsating flows

A packing as a porous body for burners, in particular for heating systems, is provided with a housing having an inlet for a gas/air mixture as a combustable gas mixture, a combustion chamber, an ignition device in the combustion chamber and an exhaust gas outlet. The combustion chamber is at least partly filled with a three-dimensional ordered packing of heat resistant ceramic material, foil material, or sheet metal material having continuous hollow cavities for the formation of a defined flame zone.
