电蒸汽锅炉运行中向外供汽应该注意哪些问题?

1、蒸汽锅炉供汽前,应进行暖管。目的是使管道、阀门、各附蒸汽锅炉件的温度缓慢上升,不可骤热,避免由于管道或阀门因温差过大,产生应力而造成损坏。   
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、暖管时,应打开分汽缸疏水器的旁通阀,逐渐开启蒸汽主阀,使蒸汽预热母管后再进入分汽缸,进行暖缸。   
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、当母管和分汽缸内凝结水排除后,关闭疏水器旁通阀,观察锅炉压力表与分汽缸上压力表指示压力是否相等,然后全部打开主汽阀及分汽缸的分支送汽阀向系统供汽。   
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、送汽过程中应观察水位计水位,注意补水并维持炉内汽压。  
Send steam process should be observed water level gauge, pay attention and maintain the furnace steam pressure.
