Description
(54) епосоБ очистки ТЕПлооБМЕНных АППАРАТОВ (54) EPOSOB CLEANING HEAT-EXCHANGE DEVICES
от коксовых ОТЛОЖЕНИЙfrom coke deposits
рани , котора не превышает . В конце выжига кокса температуру смеси .воздух:(вод ной пар) на в темплообменник вновь поднимают до 450®С, а соотношение воздух: вод ной пар медленно довод т до 1:5. По достижению температуры продуктов сгорани равной температуре паровоздушной смеси на выходе из печи процесс выжига (очистки) считают. / законченным, прекращают подачу воздуха в печь, тушат ее, теплообменник охлаждают. Врем очистки составл ет 28-30 ч. При опрессовке теплообменника пропусков не обнаружено.injuries that do not exceed. At the end of the coke burning, the air mixture temperature (water vapor) is again raised to the heat exchanger to 450 ° C, and the air: water ratio is slowly brought to 1: 5. To achieve the temperature of the combustion products equal to the temperature of the vapor-air mixture at the exit of the furnace, the burning process is considered. / finished, stop the flow of air into the furnace, extinguish it, the heat exchanger is cooled. The cleaning time is 28-30 hours. When molding the heat exchanger, no gaps were detected.
Технико-экономическа эффективность способа заключаетс в том, что длительность очистки снижена в 2,5 раза, а развальцовка устранена полностью .The technical and economic efficiency of the method lies in the fact that the cleaning time is reduced by 2.5 times, and the flaring is completely eliminated.
