(54) СПОСОБ РАБОТЫ КОТЕЛЬНОЙ УСТАНОВКИ(54) METHOD OF OPERATION OF BOILER INSTALLATION
Изобретение относитс к области теплоэнергетики и может быть использовано при эксплуатации котельник установок , с устройствами дл очистки .дымовых газов.The invention relates to the field of power engineering and can be used in the operation of boiler plants, with devices for cleaning smoke gases.
Известен способ работы котельной установки, включающий дробевую очистку котельных поверхностей нагрева l1There is a method of operation of a boiler plant, including shot cleaning of boiler heating surfaces l1
Недостатком этого способа вл етс существенное повыьюние выбросов твердых веществ в атмосферу во врем очисток котельных поверхностей нагрева при работе котельной установкй.The disadvantage of this method is a significant increase in the emissions of solid substances into the atmosphere during the cleaning of boiler heating surfaces during operation of the boiler installation.
Известен также Способ работы котельной установки путем периодической очистки в Процессе ее работы поверхностей нагрева котла и осадительных поверхностей золоуловител , причем очистки указанных элементов котельной установки могут совпадать по времени 21.Also known is the method of operation of the boiler plant by periodically cleaning the boiler heating surfaces and precipitating surfaces of the ash collector in the process of its operation, and the cleaning of these elements of the boiler plant may coincide in time 21.
Недостатком известного способа вл етс то, что в периоды совпадени по времени очистки котельных поверхностей нагрева при работе установки и отр хивани осадительных поверхностей золоуловител , выброс в атмосферу твердых веществ возрастает как за счет увеличени запыленности газов перед золоуловителем, так иThe disadvantage of the known method is that during periods of coincidence in the cleaning time of the boiler heating surfaces when the installation is working and removing the precipitating surfaces of the ash collector, the emission of solids into the atmosphere increases both due to an increase in the dust content of the gases in front of the ash collector and
вследствие снижени эффективности последнего в период отр хивани осадительных поверхностей, например электродов электрофильтра.due to a decrease in the efficiency of the latter during the period of drying of the precipitation surfaces, for example, electrostatic precipitator electrodes.
Целью изббретени вл етс улучшение очистки дымовых газов.The goal of avoidance is to improve flue gas cleaning.
Указанна цель достигаетс тем, что согласно способу очистку поверхностей нагрева и осадительннх поверх10 ностей золоуловител производ т поочередно .This goal is achieved in that, according to the method, the cleaning of the heating surfaces and precipitating surfaces of the ash collector is carried out alternately.
Способ осуществл етс следующим образом.The method is carried out as follows.
1515
При работе котельной установки сначала производ т очистку осадительных поверхностей золоуловител , например электрофильтра, а затем осуществл ют останов механизмов отр хивани 20 осудительных электродов по сигналу датчиков, фиксирующих начало очистки поверхностей нагрева котла.During the operation of the boiler plant, the precipitating surfaces of the ash collector, for example, an electrostatic precipitator, are first cleaned, and then the stop mechanisms of the 20 sluggish electrodes are stopped by a signal from the sensors that record the start of cleaning the boiler heating surfaces.
Очистку осадительных поверхностей золоуловител возобновл ют после прекращени очистки поверхностей нагре25 ва котла.The cleaning of the precipitating surfaces of the ash collector is resumed after the termination of cleaning the surfaces of the heating of the boiler.
Возможна и обратна очередность очистки поверхностей нагрева котла и осадительных поверхностей золоуло30 вител .It is also possible to reverse the sequence of cleaning the heating surfaces of the boiler and the precipitating surfaces of the ash unit.
таким образом, предлагаемый способ дает возможность улучишть очистку дымовых газов и, следовательно, сннэйть выброс ЭОЛЫ в атмосферу.Thus, the proposed method makes it possible to improve the cleaning of flue gases and, therefore, to sniff the release of EOLA into the atmosphere.
