Application of image processing for spray angle measurement of furnace oil gun nozzle

In the modern era of the coal fired boilers combustion optimization plays a vital role for increasing the boiler efficiency and reducing the production of hazardous waste gases like NOX, SOX etc. Hence to optimize the combustion there are different ways to control the parameters of boiler combustion like 3T method, which includes Time, Temperature and Turbulence. Each of them can be controlled by controlling variety of parameters available in boiler combustion. One of the methods to control the turbulence of the fire ball is to control firing of the coal and the oil burner´s angle and the direction in accordance to get proper tangential firing. In this paper we propose a method based on digital image processing for measurement of furnace oil gun nozzle spray angle measurement using Hough transform.
