Document Type and Number:
WIPO Patent Application WO2003034819
Kind Code:
A3
Abstract:
The invention relates to a method of measuring the NOx content in the fumes produced by means of combustion in a furnace (46). The inventive method is characterised in that it comprises the following steps, consisting in: (a) during the combustion, measuring at least one pressure datum in the furnace, at least one temperature datum in the furnace and/or in the fumes resulting from the combustion, and at least one datum that is representative of the nitrogen concentration in the fumes; and (b) introducing said data, or data processed or obtained from said data, as input data for a neural network which provides at least one output datum that is representative of the NOx concentration or content in the fumes resulting from the combustion.
