Economiser kya hai? Eske types, structure or function kya kya hain?

Thermal Power Plant ke Boiler me Economiser ka ek important role hai esse boiler ki Energy improve hone wali device hai jisse Boiler ki bohot Energy efficiency badh jati hai, Economiser kya hai? Types, definition, functions material aur structure k liye yah post pdhe

What is Boiler Economiser in hindi

Actually ye boiler me Heat Exchang ka kam krti hai mtlb yah heat exchanger hote hain jo water k heat ko exchange ka kam krti hai ese pre-heater bhi kahte hain.

 

west heat recovery boiler Economiser

Boiler water ko sensible aur latent heat dekr steam me convert krne k liye bnaya gya ek device hai.

Esme flue gas k heat ka temperature ek amount me jarurt pdhti hai jisse Economiser ka water ek constant pressure aur temperature k sath steam vapour me change hai.

Whrb me actually 2 economiser hote hain 1 aur 2 lekin dono same hi hote hain inke temperature approx 182 se 279°C hote hain.

Whrb Boiler me jab Exhaust Flue gas ka heat Economiser me ati hai to esme water ka temperature increase krke Boiler drum me bhejti hai taki boiler k drum aur super heater ko heat dene ka load or steam me convert krne k liye kam heat aur temperature deni pde jisse eski boiler efficiency bhi bdh jati hai aur heat load kam ho jati hai.

Whrb Boiler Economiser

Boiler ki Overall efficiency 3-5% Economiser increase kr deti hai sath hi me ye boiler ki life bhi bdhati hai.

 

Boiler Economiser functions

Boiler me Economiser heat transfer k principal per work krta hai, Eco-2 se Eco-1 me heat ka transfer high se low temperature me hota hai.

Jab Feed pump se water Economiser k inlet header se inlet krta hai to eske tube me water hota hai use flue gas ya Exhaust gas Economiser k casing duct se outlet gota hai jo high temperature k sath hota hai jisse boiler me jane se pahle yah water ko heat kr deta hai,

 Esko Pre-Heater bhi kahte hain, esme flue gas niche se aur coil me water uper se ata hai jisse feed water ka temperature badh jata hai jisse ese pre heat kr deta hai eska flow direction opposite hone k karan ese counter flow kahte hain.

Water tube boiler me Economiser k coil tube me water hota hai aur eske casing duct area me flue gas, jabki fire tube boiler me tube k ander flue gas just opposite of water tube boiler.

Boiler me Economiser ke types

Boiler me Economiser, operation aur functions k hisab se classified kiya gya hai,

Temperature ke adhar per Boiler Economiser ko Pressurized aur non-pressurized name se 2 types me jarurt k base per bnaya gya hai.

Pressurized Economisers

Ye Boiler Economiser jab water ka atmosphere pressure per temperature Normal Boiling Point se jyada ho to wahan pressurized Economiser use kia jata hai, es type ke Economiser ko Pressurized Economisers kahenge.

Non-pressurized Economisers

Jab normal Boiling point se bhi kam temperature aur atmospheric pressure ka use krte hain tab es type k Economiser ko Non-pressurized Economiser kahte hain.

 

Economiser Tube material

Actually Economiser me carbon steel ( CS ) use kia jata hai eska code SA 210 Grad A aur B dono mil jata hai.

 

Structure of Whrb Economisers

West heat recovery boiler (whrb) ke 2 Economisers hote hain aur dono me 2- 2 parts hote hain jo bank- 1 dusra bank- 2 hota hai ye part coil ka ek group hota hai ek group upper jo bank- 1 hota hai dusra niche jo bank- 2 hota hai aise gi Economiser-1 aur Economiser-2 dono me hota hai esme total 26 Coil tube hote hain jinse milkr ek Economiser ready hota hai eska common header hota hai jo inlet aur outlet k liye hota hai.

Economisers ki fix koi length aur hieght nhi hoti lekin whrb me 26 coil ki ek buddnle hoti hai jisse ek Economiser kahte hain.

 

Conclusion

Thermal power plant Boiler me Economiser ka ek important role hota hain jisse Plant ki energy aur efficiency increase ho ske Economisers ki full details Economiser kya hai? Economiser functions and types aur explaination sab humne es post me cover kia hai ap es post ko read krke knowledge aur gyan le skte hain jisse apko eske bare me achha khasa knowledge ho hi ayega.

Power plant ke Jyada information k liye ap humare websites k others post ko read kre jahan fully details aur whrb, turbine, PP, working of power plant sab hai.
