Taiyuan reason to run the boiler combustion control burn pulverized coal fire in a two time intervals too close to the wind speed is too small to cause ignition of pulverized coal interval too. In operation, the total control of the primary air pressure is too low, it may cause a fire spaced too close, causing the burner nozzle to overheat and distort until damage. 3 secondary air velocity interval too low can also cause a fire, causing damage to the burner nozzle. 4 changes affecting coal coal quality better, after volatile progressive industrial burner, primary air vents interval becomes nearly pulverized coal fire, running staff failed to adjust the primary air and secondary air, in order to adapt to changes in coals . 5 coal fineness too fine coal quality analysis report from two months to see, combustible coal-based power plant running at 15% volatile matter and 23% ash at 25%, corresponding to control coal fineness should R90zj 14.5% to 21%, while coal fineness R90 operational control of about 12%, resulting in a wind vents spaced too close pulverized coal fire, causing damage to overheat and distort until burner nozzle. 6 low-load operation is not enough to cool the upper primary air vents in the low load operation, is not put into use primary air nozzle, almost in a dry state, can not be sufficiently cooled, resulting in overheating of the burner, until deformation damage. Countermeasures burning boiler burner burner 1. improve the structure and wear performance of direct ignition of pulverized coal burner programmable preheat burner tube, a tube wall thickness and respond within an appropriate length of the barrel design improvements, the choice of quality alloy steel burner, increase wear resistant properties. For pulverized coal concentrate, preheat burners, burner design should take full account of wear resistance, high temperature resistance preheating chamber. 2. The upper primary air vents to increase the perimeter wind design perimeter wind can play such a role: high load Aging methanol burner, perimeter wind is open, this time the perimeter of the wind's role is to strengthen the primary air strength to prevent the pulverized coal expansion and wash around Wall and replenish the oxygen demand of combustion; perimeter presence also weakened wind around Wall reducing atmosphere to avoid the occurrence of hot water wall corrosion; at low load, to meet discontinuation of mill when a station, the upper one air vents cooling requirements, to prevent burn burner. According to Jiangsu Province plant boiler burners research situation, at high loads, the wind can be put into operation perimeter effectively controlled pulverized coal burner ignition interval. Methanol, oil burner, Luliang burner, the sun can be environmentally friendly by Shanxi Environmental Protection Equipment Co., Ltd. sun. Shanxi Environmental Protection Equipment Co., Ltd.
