Description

Изобретение относитс  к тепловым агрегатам, в частности стекловаренным печам в производстве тарного, сортового и технического стекла.The invention relates to heat units, in particular glass furnaces in the manufacture of container, high-grade and technical glass.

Целью изобретени   вл етс  обеспечение очистки насадок регенераторов стекловаренных печей.The aim of the invention is to provide cleaning of the nozzles of regenerators of glass melting furnaces.

Способ очистки регенераторов осуществл ют следующим образом.The method of cleaning regenerators is carried out as follows.

Во врем  очистки регенераторов через 3 мес дополнительно устанавливают горелки и нагревают до 1100°С в течение 4 ч. При этом соединени , образовавшиес  на поверхности огнеупоров в результате конденсации окислов натри , кальци , магни  и др., расплавл ютс  и стекают в поднасадоч ное пространство.During the cleaning of the regenerators, after 3 months, the burners are additionally installed and heated to 1100 ° C for 4 hours. In this case, the compounds formed on the surface of the refractories as a result of the condensation of sodium, calcium, magnesium oxides, etc., melt and flow into the sub-head space .

В результате такой термической очистки аккумулирующа  способность огнеупоров насадок регенераторов практически полностью восстанавливаетс . Через 6 мес работы печиAs a result of this thermal cleaning, the storage capacity of the refractory materials of the regenerator nozzles is almost completely restored. After 6 months of operation

в результате засорени  насадок средн   температура воздуха, подогреваемого в регенераторах, снизилась с gSO-SZO C до 850-860°С. Послеas a result of clogging of nozzles, the average temperature of the air heated in the regenerators decreased from gSO-SZO C to 850-860 ° C. After

термической очистки насадок температура воздуха повысилась до 910-920°С. Восстановилось и гидродинамическое сопротивление насадок.thermal cleaning nozzles air temperature has risen to 910-920 ° C. Restored and hydrodynamic resistance nozzles.

Эффект использовани  термическойThermal effect

очистки насадок регенераторов складываетс  из экономии топлива в пределах 3-6% за счет поддержани  посто нной аккумулирующей способности насадок регенераторов, экономииcleaning of regenerator nozzles is the sum of 3–6% fuel economy due to maintaining a constant accumulator capacity of regenerator nozzles, saving

огнеупоров дл  насадок (ремонт- - замена насадок производитс  один раз в течение кампании печи) и сокращени  расходов на гор чий ремонт. В зависимости от размеров и производительности печей экономический эффект от внедрени  термической очистки регенераторов в расче-ЕЗ на одну печь составл ет 25-40 тыс. руб. в год.refractories for nozzles (repair - replacement of nozzles is made once during the kiln campaign) and reduce the cost of hot repairs. Depending on the size and performance of the furnaces, the economic effect from the introduction of thermal cleaning of regenerators in the calculation of EZ per furnace is 25-40 thousand rubles. in year.
