Method 1: drying method

此法就是在停爐時(shí),當(dāng)鍋爐水的溫度降100～120℃時(shí),進(jìn)行放水.當(dāng)水放盡后,利用爐內(nèi)余熱,點(diǎn)微火或引入爐膛熱風(fēng),將鍋爐內(nèi)表面烘干。

This method is to discharge water when the temperature of boiler water drops to 100-120 ℃ when the boiler is shut down. When the water is exhausted, the boiler inner surface is dried by using the residual heat in the furnace, igniting a slight fire or introducing hot air into the furnace.

方法二：燥劑法:

Method 2: drying agent method

干燥劑法就是在鍋爐停用后,當(dāng)鍋爐水的溫度降100～120℃時(shí),將鍋爐內(nèi)的水放掉,利用爐內(nèi)余熱,將金屬表面烘干,并清理沉積在鍋爐水系統(tǒng)內(nèi)的水垢和水渣.然后在鍋爐內(nèi)放入干燥劑,保持金屬表面干燥,不讓腐蝕.常用的干燥劑有:無水氯化鈣、生石灰、硅膠.

The desiccant method is to drain the water in the boiler when the temperature of the boiler water drops to 100 ~ 120 ℃ after the boiler is out of service. The metal surface is dried by using the residual heat in the furnace, and the scale and water slag deposited in the boiler water system are cleaned up. Then the desiccant is put into the boiler to keep the metal surface dry without corrosion. The commonly used desiccants are: anhydrous calcium chloride, quicklime and silica gel

方法三：濕法保養(yǎng)

Method 3: wet maintenance

濕法保養(yǎng)一般適用于停爐時(shí)間不超過一個(gè)月的鍋爐的保養(yǎng)。停爐后按規(guī)定時(shí)間放盡爐水，將水垢、水渣、煙灰清理干凈。

Wet maintenance is generally applicable to the maintenance of boilers whose shutdown time is less than one month. After the boiler is shut down, the boiler water shall be drained according to the specified time, and the scale, water slag and ash shall be cleaned up.

方法四：壓力保養(yǎng)

Method 4: pressure maintenance

新鄉(xiāng)燃油燃?xì)忮仩t廠家認(rèn)為適用于生產(chǎn)備用鍋爐或停運(yùn)進(jìn)行短暫檢修時(shí)間不超過一周的鍋爐。停爐后把爐水放盡，將爐內(nèi)的水垢、水渣清理干凈，重新加入合格軟化水。

Xinxiang oil and gas-fired boiler manufacturers believe that it is suitable for production of standby boilers or boilers that are out of service for a short period of time less than one week. After shutdown, drain the boiler water, clean up the scale and water slag in the furnace, and add qualified softened water again.

定期用小火加熱，或定期利用相鄰鍋爐的蒸汽加熱爐水，使鍋爐內(nèi)的爐水溫度夏季應(yīng)保持在環(huán)境溫度+10℃左右，冬季應(yīng)使?fàn)t水不凍結(jié) ，關(guān)閉放空閥、排污閥和放水閥，不讓漏水。

Heat the boiler water regularly with small fire or steam from adjacent boilers to keep the boiler water temperature in the boiler at + 10 ℃ in summer and keep the boiler water from freezing in winter. Close the vent valve, drain valve and drain valve to prevent water leakage.

方法五：熱法

Method 5: thermal method

此法用于停爐時(shí)間在10天以內(nèi). 方法是在汽包上方安裝一個(gè)水箱,用管子和汽包相聯(lián)通.鍋爐停用后,充滿除過氧的水,水箱中大半充滿著水.水箱用外來蒸汽通入加熱,使水箱中水經(jīng)常保持沸騰狀態(tài).所述做好課后及時(shí)復(fù)習(xí)的要點(diǎn)適用于本環(huán)節(jié)外，還必須注意以下幾點(diǎn)：

This method is used to stop the boiler within 10 days. The method is to install a water tank above the drum and connect the pipe with the drum. After the boiler is shut down, it is filled with water excluding peroxide, and most of the water tank is full of water. The water tank is heated by external steam to keep the water in boiling state. The key points of timely review after class are applicable to this link, and the following points must be paid attention to:
