Method and Device for Monitoring the Combustion Process in a Power Station on the Basis of an Actual Concentration Distribution of a Material

Abstract

Methods and a device for monitoring the combustion process in a power station are provided. An actual concentration distribution of a material and/or an actual temperature distribution are measured in the combustion chamber. Conclusions are drawn regarding the type of combustion material on the basis of the measured actual concentration distribution or temperature distribution. A concentration distribution or temperature distribution of a material that has been determined using a sample fuel is compared with the measured actual concentration distribution or temperature distribution.
