介紹6噸熱水鍋爐停爐有效保養(yǎng)方法
This paper introduces the method of effective maintenance of 6 tons hot water boilers
由于6噸熱水鍋爐故障或者停電的原因鍋爐需要停爐，蒸汽鍋爐停留之前應(yīng)該停止鍋爐的燃燒，慢慢的降低鍋爐的溫度直至達(dá)到鍋爐沒有壓力，停爐之前要把水泵、鼓風(fēng)機和引風(fēng)機關(guān)掉。
Need to stop because of boiler failure or outage boiler furnace, steam boiler stop should stop before the boiler combustion, slowly until the lower the temperature of the boiler is up to no pressure boiler, boiler stop before to turn off the water pump, fan and induced draft fan.
鍋爐停爐后的維護(hù)頤養(yǎng)，分為爐體外部和鍋內(nèi)的防腐頤養(yǎng)。鍋內(nèi)的防腐頤養(yǎng)，依據(jù)停爐時間的長短選擇干法頤養(yǎng)和濕法頤養(yǎng)兩種。在鍋爐長期停用時，應(yīng)非常留意爐體外部的防腐頤養(yǎng)問題。首先在鍋爐停爐冷卻后，必需盡量徹底肅清受熱面的積灰和爐排上部、爐體下部的灰渣。然后要堅持煙道有一定的自然通風(fēng)。普通狀況下，為了防潮應(yīng)在爐膛、煙道中放置枯燥劑。After the boiler is stopped, the maintenance of the summer is divided into the outside of the furnace and the inside of the pot. The inside of the pot is embalmed, according to the length of the pit stop time and the way of the summer and wet summer. When the boiler is discontinued for a long time, it is important to keep an eye on the embalming problem of the outside of the furnace. First, after the boiler is cooled, it is necessary to completely clean up the ashes of the heating surface and the top of the grate and the ashes of the lower part of the furnace. Then stick to the flue and have certain natural ventilation. In normal condition, to prevent the moisture from the furnace, the flue should be placed in the fire. If lime is used as a dry agent, it should be placed at about 3kg per cubic meter of furnace or flue. When placed, close all ventilation doors tightly. The powdered lime should be changed.
如鍋爐房位置低洼，停爐期間空中泛潮嚴(yán)重時，則應(yīng)采用經(jīng)常小火烘烤和放置枯燥劑相分離的方法。假如鍋爐鍋爐時間很長，在徹底肅清煙灰后在爐體金屬表面面涂以紅丹油或其它防腐漆。
If the boiler room is low, and the air tide is severe during the stop furnace, it should be used in the method of baking and placing the dry agent. If boiler time is very long, after thorough purging ash, the surface of the furnace metal surface is coated with red Dan oil or other anticorrosion paint.
至于爐體內(nèi)部停爐的防腐頤養(yǎng)辦法，則要按停爐時間的長短來定。普通狀況下，停爐不超越一個月的可用濕法頤養(yǎng)，一個月以上的應(yīng)采取干法頤養(yǎng)。
As to the preservation of the furnace inside the furnace, it is determined by the length of the stop furnace. In ordinary condition, stop furnace is not exceed a month of usable wet law to be raised, more than a month should adopt dry law to be taken care of.
干法頤養(yǎng)時要留意以下幾點問題：枯燥劑不要直接接觸鍋爐金屬外表，可裝在鐵盤等容器內(nèi);放置枯燥劑后，要關(guān)嚴(yán)手孔和其它孔蓋，汽、水管道上的閥門必需截斷;生石灰變粉應(yīng)及時改換。
When you do the work, you should pay attention to the following questions: the dry agent should not be directly exposed to the metal surface of the boiler, but it can be installed in the iron tray and other containers. After the boring agent is placed, the valve must be cut off for the hole and other holes. The powdered lime should be changed in time.
