Abstract:This article studies the running of DZL58-1.6/150/90-AⅡ boiler of DengFeng boiler space in two heating periods, gets the secondary air blasting program though the experiment, and makes experimental research on boiler effects directed at the fullness of fire-bed, works out a reasonable length of the fire-bed, propounds the heating boiler must pay attention to the mixing work of fuel coal. Based on the coal measures in front of boiler, this article established the dynamic assessment system about heat and coal consumption. From the two aspects of technology and management, makes the operating efficiency of boiler above 82%.
