Analysis of transformation of methanol replacing diesel in ignition system in coal-fired boiler
Several common ignition methods of coal-fired boilers were introduced.In view of the problems of incomplete combustion of oil mist,black smoke emission and large resistance of tail dust collector bag in the diesel ignition and combustion stabilization system of 3 coal-fired boilers in Changqing Energy Chemical Company,the diesel ignition and combustion stabilization system was reformed by using self-produced clean green methanol instead of diesel as fuel.After the transformation,the above problems were completely solved,and the fuel cost could be saved by 48%.In addition,the new problems that arose in the methanol ignition and combustion stabilization system were solved.
