Whrb boiler kya hai ? Ye kaise work karta hai ? Full Explain

Hello friends apko pta hi hoga ki India me power plants ki kami nhi hai jo plants me electricity power production krta hai and yah power production k liye plants Boiler ka use krke karte hain and yah kai types k hote hain but hum apko sabse easy and simple “West Heat Recovery Boiler” (WHRB) Bolier k bare me btayenge ki whrb boiler kya hai ? Ye kaise work karta hai ? Esse power production kaise hota hai ? Whrb boiler accessories, aur Complete work principal.  

WHRB Boiler


How to produce Electricity by boiler in power plant?

Whrb boiler ho ya koi aur boiler power plants sabhi me flue gas aur water ka use krke High pressure and temperature steam bnakr Turbine rotate krke turbine k shaft se juda ganarator kinetic energy ko Electricity energy me Convert karta hai.

WHRB Boiler kya hai ?

Ye boiler ” West Heat Recovery Boiler ” hai esme DRI or kilan (sponge iron Production plant) k post combustion chember se nikli west flue gas ko use krke Boiler me water ko Steam me Convert krke turbine k rotation se generator se electricity produce krte hain.

DRI kilan k flue gas ka temperature Approx 850 °C se 950° C ka hota hai jisse Boiler me Water ko Steam me Convert kiya jata hai and WHRB Boiler me Steam ka Temperature output 520°c se 525°c and pressure 89 kg/cm^2(g) hota hai.

WHRB Boiler me kya kya hota hai?

West Heat Recovery Boiler me apko Accessories mil jate hain jaise Economizer -1 & Economizer- 2 , Evaporator-1 & Evaporator-2 and Whrb boiler Drum, boiler water wall panel, drum down commer, Evaporator down commer, water wall pannel Riser jo drum me enter krti hai yah total 12 pipe hoti hai jo water wall header se nikal kr drum me jati hai.

Esme apko Drum se IBD aur CBD line hoti hai, Boiler k water wall panel me Soot blower lgi hoti hai jo 2 type ki hoti hai ek LRSB and ek RSB boiler k main outlet steam line me motorize valve lgi hoti hai and boiler k chahe steam line ho ya feed line ho wahan apko ek Bypass valve jarur hi mil jata h jo emargency k liye hota hai.

Working of WHRB Boiler

whrb kya hai ? Eski working process janna chahte hain to yah post apko avsya ki benefits degi to chaliye hum West heat Recovery Boiler ki working Process samjhte hain.

1. Sabse Phle Dm plant se water Dearator se Hote hue Boiler feed water (BFP) pump k through jab feed water line se yah water sabse phle Economizer-1 k Top inlet header me Enter krta hai starting me eska temperature 130°C ka hota hai fir Eco- 1 me Enter hota hai to yahan k coil tube ka temperature 193°c hone k karan water ka temperature 182°c ho jata hai fir yah Eco- 1 k outlet header se nikal jata hai.

2. Economizer -1 se Economizer- 2 ka ek connecting pipe link hota hai jo Eco- 2 k inlet header me water 182°c k sath Enter krta hai. Economizer- 2 me es water ka temperature 279°C ka ho jata hai because Economizer-2 k coil tube ka temperature 295°C hota hai esliye Economizer -2 k outlet header se jo water nikalti hai wo 279°C k temperature k sath niklti hai.

3. Eco- 2 ka link boiler Drum se hota hai aur es Boiler Drum ka temperature 313°C hota hai esliye water ka temperature bhi 313°C ka ho jata hai.

4. Boiler k drum k niche side me ek down commer pipe lga hota hai jiska link Evaporator-1 and Evaporator-2 se hua hota hai jika outlet header ka link fir se drum me hota hai yah dono Evaporators Boiler k Efficiency badhane me help krta hai aur kuchh bache water ko steam me convert krta hai.

5. Jab Economizer- 2 se Water drum me jati hai to fir water main down commer se yah Ring header se hote hue Boiler k water wall pannel se chadhkr yah Risers se Drum me fir se jata hai water wall ka temperature 341°C ka hota hai.

6. Drum me water aur Steam dono hota hai water niche jata hai aur steam upper ki taraf jata hai esliye Drum se Steam 313°C k temperature k sath upper k riser pipe ka link boiler k primary super Heater k inlet header se hota hai.

7. Primary Super Heater k coil tube ka temperature 434°C hota hai, Jab steam Drum se Primary super heater me High temperature aur pressure k sath Steam Enter krta hai to Primary super heater k coil ka 434°C temperature Steam ko aur high temperature deta hai jo 313°c se yah 395°C ka ho jata hai.

8. Eske Bad Primary super Heater k outlet link Secondary super heater k inlet link se juda hota hai jise Desuper heater bhi kahte hain, Secondry Super heater k coil tube ka temperature 575°C hota hai jisse Steam 525°C ho jata hai aur Pressure yahan apko 89 kg/cm^2(g) ka milta hai.

9. Secondry Super Heater k outlet header main steam line se juda hua hota hai esme apko Temperature 525°C aur Pressure 89 kg/cm^2(g) ka hota hai jise steam line me lage motorized valve ko DCS se control krke open krte hain aur yah High temperature and pressurized Steam turbine me jata hai.

10. Jab Steam 525°C temperature aur 89°kg/cm2(g) turbine me jata hai to Turbine Rotate hone lgti hai aur yah gear box se judi hui hoti h jo Turbine ko extra force dene me help krti hai aur turbine k shaft generator se juda hua hota hai jisse generator kinetic Energy ko Electric Energy me Convert karta hai aur Electricity produce hota hai.

Above me humne apko Whrb kya hai ? Aur eske working process k bare me btaye hain ap ye padhkr process jan jan skte hain aur Whrb project ya running ki details es post se ya humare esse related dusre Education post se le skte hain

apko yah post jarur hi knowledge dega ager ap power plant k bare me janna chahte hain to whrb boiler easily samjh jayenge ager ap es post ko achhe se read kre to.   Thank You!
