Pressure increase hone k karan agar drum lvl low jata h toh hp lp bypass line me lena h... Open karna h.. vent itne high preasure me thode kholte hai..
Water supply control valve by pass may not be provided on some feed water system. If by pass is provided then open it as per the load demand feed water demand. Over feeding on full load can trip boiler drum high level to avoid carry over to turbine through Super heated steam. If drum level low occurs then FC must be open on Man mode or Start Stand by feed pump with in some seconds. We have been facing these all situations.We operated 1000 Ton/h feed with two fw pumps like 510 ton/h each pump output. If drum level low not controlled then boiler MFT observed to save boiler tubes bulging.
Hi sir... I have back dated boiler attender experience certificate (2017-2019) , now can i apply for 2nd class boiler exame..? Is that ex.certificate is valid .?
Due to moisture available in service air
We used instrument air
