Determining the air excess in the heating of coke furnaces. 2. Sampling and analysis

Resumo

A sampling method for the combustion products is proposed in determining the air excess at coke batteries. The selection of the sampling location and method may distort the results obtained in analysis of their composition. Systems for sample analysis are considered. In the case of coke-oven gas, determination of the combustion-product composition by automated analysis of samples from the heating channels is recommended. Tubes of quartz or other refractory materials may be used in the analysis.
