Paper Abstract

There is no method of direct measurement of amount coal dust supplied to the burner, as well as a primary air. It is important in avoiding flame instabilities that could lead flame extinguishing and thus, improve both safety and combustion quality. One of the quickest way of drawing information of a combustion process is to analyze its radiation. The article presents investigation of flame image features, that could point to a state of unstable combustion. Several combustion tests of pulverized coal have been done, generating stable and unstable state of combustion. In this article, some flame image parameters as image energy, entropy and median have been investigated as combustion quality pointers.
