1.Boiler ka blowdown valve fail hojane per kya karo ge ?
A.Feed water Jith na bhi lage hane drum drum level maintain karna hai.
check karna hai kithna pani blowdown valve mese passing horaha hai.
Agar pani kam loss horaha hai tho Acceptable hai tho boiler running me rakhe, shutdown clearance milnetak.
Agar Blowdown valve mese pani bahoth loss horaha hai acceptable nahi hai tho Boiler ko shut down kare Aur Blowdown valve ko change ya repair kare.
2.Boiler (Blast) explosion hone ka kya karan hosakta hai ?
A.Boiler ka pressure high positive hone ke karan bhi Boiler explosion hosakta hai.
Agar Boiler protection aur inter locks by pass kar ke chalarahe hai tho use condition me major folt bad jathe hai iske karan bhi boiler explosion hosakta hai.
scale aur corrosion agar pressure parts me hoga tho bhi boiler explosion hosakta hai.
3.Boiler ka flue gas outlet temperature (high) badne ka kya karan hosakta hai?
Ecnomizer aur (APH)clean kare.
Aur maintain kare flue gas temperature as per manufacturer guide yani Aap kis company ka Boiler hai wo jithna flue gas temperature maintain karne ki guide lines diya hai usi prakar hame maintain karna hai.
Boiler me Higher moisture content fuel ko burn karrahe hai use condition me bhi flue gas temperature bad tha hai is liye Boiler me limit moisture content wala coal ko burn karrahe hai tho use condition me bhi flue gas temperature bad tha hai is liye boiler me limit moisture wale fuel ko burn karraha hai.
4.Boiler me fuel consumption high bad raha hai iska kya karan hosak tha hai?
Incomplete combustion horaha hai tho uss condition me bhi coal consumption bad jatha hai.
Furnace combustion Draft excess air aur fuel moisture maintain karna hai 3ts ke according
HP aur LP heater se hame ecnomizer inlet feed water ko increase karna hai yani bada na hai.
Shoot heat transfer achche se nahi horaha hai tho hame shoot blowers ko regularly open karna hai.Aur rated pressure aur temperature ko operate karna hai.
5.Boiler me clinker formation hone ka kya karan hai?
Low moisture content coal ka uss karnese bi furnace me clinker formation hoga.
Air ka aur fuel ka mix sahi se nahi hoga tho bi clinker formation hoga.
Agar hum coal high ash fusion temperature ka use karrahe hai tho uss condition me bi clinker form hosak tha hai.
Sudden startup ya stop karrahe hai ya power cut horaha hai tho uss condion me bi clinker form hosakta hai.
Agar hum high temperature me boiler ko run karrahe hai uss se boiler ka bed temperature high coal feeding ke karan temperature bad ke clinker form hoga is liye hame boiler ka bed tempwrature 850 se 900 ke beech me maintain karna hai.
6.Boiler drum me corrosion rate ko kaise control karna hai?
Maintain boiler feed water ph desired range ke motha bik.
Boiler feed water me oxygen %0.007 ppm tak raakh na hai oxygen scavenger chemical dosing karthe huye.
DM water storage tank properly sealed hona chahiye.
Condenser leak hai tho jald se jald find karke close karna hai.
