1、蒸汽鍋爐供汽前，應(yīng)進(jìn)行暖管。目的是使管道、閥門、各附蒸汽鍋爐件的溫度緩慢上升，不可驟熱，避免由于管道或閥門因溫差過大，產(chǎn)生應(yīng)力而造成損壞。
Before steam boiler for the steam, should be warm tube. The purpose is to make the pipes, valves, each attached to a steam boiler temperature to rise slowly pieces, not sudden heat, to avoid the pipe or valve due to the temperature difference is too large, resulting in stress and damage.
2、暖管時(shí)，應(yīng)打開分汽缸疏水器的旁通閥，逐漸開啟蒸汽主閥，使蒸汽預(yù)熱母管后再進(jìn)入分汽缸，進(jìn)行暖缸。
When the warm pipe, open the sub-cylinder trap bypass valve, gradually open the main valve steam, the steam preheat mother tube and then into sub-cylinder, the cylinder warm up.
3、當(dāng)母管和分汽缸內(nèi)凝結(jié)水排除后，關(guān)閉疏水器旁通閥，觀察鍋爐壓力表與分汽缸上壓力表指示壓力是否相等，然后全部打開主汽閥及分汽缸的分支送汽閥向系統(tǒng)供汽。
When the condensation of water inside the main pipe and sub-cylinder is removed, close the trap bypass valve, pressure gauge on the boiler pressure gauge and observation points indicated pressure cylinder are equal, then the main steam valve fully open branches and sub-cylinder steam valve to send to the system steam.
4、送汽過程中應(yīng)觀察水位計(jì)水位，注意補(bǔ)水并維持爐內(nèi)汽壓。
Send steam process should be observed water level gauge, pay attention and maintain the furnace steam pressure.
