बहुत अच्छा गुरू जी प्रणाम
Sir why both thrust load and radial load is necessary for every Steam turbine and Boiler feed pump???
Sir, kindly explain how to save the boiler from min. Eco. Flow trip protection when the turbine is tripped. I.e, how to take BCWP and MDBFP into service to save the boiler from Min. Eco. flow protection. I am working in BHEL 800MW unit.(MDBFP: 20.5Mw & BCWP: 830 Kw)
OK, will explain
could you please explain about IGV and VFD control (Blade pitch control) of ID fan.
IGV means throttling of flow, vfd means Speed control, Blade pitch control means control of flow by Blade angle
@@kpatelblaSir, I am asking about how the IGV and VFD plays the role in controlling the flow. You explained a video on PA fan control right? like that make a video on ID fan.
@@motive0507 sure
Sir why balancing line is provided in turbine vertical pump??
Balancing line provided to prevent Axial shift of pump rotor.
could you please tell me that at 0.6ksc if HPBP valves not closed then what will happen. please elaborate it clearly. Doubt is that if TG trip happens, but to run the boiler independently we want HPBP and LPBP to be open. But as per this 0.6ksc criteria if HPBP closed then by reheater protection boiler will also trip.So, could you please tell me that what is main reason behind that at 0.6ksc ,HPBP closes.
Hope you give reply for this
could you please tell me that what is the main reason behind turbine trip on condenser pressure high that is >0.3ksc.
To protect LP Turbine from abnormal pressure at exhaust and Condenser tubes.
@@kpatelbla At what pressure the LP turbine diaphragm will rupture?
please give reply
It is at 0.9 to 1 kg/cm2 gauge pressure in condenser.
Sir send. The copy ofmy PDF mdbfp
Sorry Docoment can't be share. If any question you may ask
could you please tell me that why 220V DC failure leads to MFT.
Without 220 Volt DC you can't run Boiler safely, as LDO gun LONV, HONV, LOTV, HAD, HAG control fails....
@@kpatelbla could you please make a video on this topic. It helps to so many
@bla could you please differentiate about the role of 24V DC and 220V DC?
