Abstract

Flame radiation intensity and its changes in time domain deliver the quickest and straight information of a combustion process. We have compared combustion of coal-biomass mixture and reference coal through flame image analysis. The aim of the research was finding flame's shape features, that could point to a state of unstable combustion, for the fuels being considered. Several combustion tests have been made in a laboratory stand for pulverized coal mixed with paper sludge (10%) with variable coal flow. The stand was equipped with scaled down (1:10) low-NO_x burner. Flame images were recorded by a standard monochrome camera and captured by a frame grabber. After conversion to black-and-white images, changes of some shape parameters such as flame area, its horizontal and a vertical dimensions and shape coefficient have been investigated.
