Sir make video on primary air fan, force draf fan, induce draft and seal air fan and line up
Very informative video sir
APH ka bhi samja dijiye..types of sealing,sector plate etc
Ok
Yes sir pls make video on aph
Sir please make video on CEP ISOLATION AND NORMALISATION
Ok
Why we are seeing suction flow in pumps like TDBFP? Why not discharge flow.And what are the conditions on which suction flow will come low,and it leads to TDBFP trip,mainly tell me impact of recirculation valve on suction flow?
To prevent cavitation with accurate measurement of suction flow if it comes below preset value pump must be tripped. Suction flow will reduce in case of Deaerator level low, if Suction valve closed in case of pump running condition, malfunction of flow transmitter.
Which factor affects high mill rejection?and how it can be reduced??coal factor definition?
Sir R- Raymond hai(founder of bowl mill)not Reynold...anyway very nicely explained.👍👍
Exactly.
Not founder, inventor.
Sir in our plant 500MW. There are total 10bowl mill.
Load is around 490MW. total 7mill in service BDFGHJK.
when mill C taken and charged then BC flame got deteriorated also BC fireball out. Why this happened sir? We support the boiler by firing but inspite of firing flame disturbed?
This happened regularly when base mill like A or B taken flame become poor?
You have to observe when taking mill in service which is creating disturbance in flame their coal nozzle to be checked in opportunity shutdown for possible misalignment and necrssary correction.
Please tell me what does it mean mill choking?And also tell me what does it sensing bowl DP is showing negative value?
. Mill bowl DP increases due to choking of Mill, and PA air not coming from MRS sustem.
Sir,which factor affects mill rejection??how it can be reduced?coal factor definition?
Main factor Specific coal if it is according to design coal rejection always less.
Does classifier is having any mesh? How the classification is happening there?
please clarify this?
It is flap type screen, can be adjust manually from outside the mill. Mounted at Mill top.
@@kpatelbla What we are adjusting?
Classifier position 1 to 10, means flap type mesh adjusted inside mill with the application of outside mounted lever.
Sir, why Turbine heatrate is high at part load? What are the exact practical reasons?
Sir, please respond... What practically happens in turbine during part loads ...
