Abstract:
1. A process for determining the NOx content in flue gas produced by combustion in a furnace, comprising: a) measuring at least one first parameter during the combustion process, said first parameter comprising datum of pressure in said furnace; b) measuring at least one second parameter during the combustion process, said second parameter comprising datum of temperature, said temperature datum being measured in the furnace, in the flue gas, or in both the furnace and the flue gas; c) measuring at least one third parameter during the combustion process, said third parameter comprising datum representative of the concentration of nitrogen in the flue gas; and d) inputting information into a neural network, wherein at least one of said input information is selected from the group consisting: e) calculating with said neural network at least one output datum, wherein the output datum is representative of the concentration of NOx in the flue gas resulting from said combustion process; and f) receiving the output datum from said neural network.
