Preheater & Calciner basic | Type of Preheater | Pyroprocessing | Cyclone

Preheater is an equipment to extract heat from the kiln gases to PRE- HEAT the raw material before being fed in to kiln.
Raw material is preheated to Calcination temperature in the Preheater.
Cyclone is cylindrical vessel with a conical bottom and a slightly enlarged top with entry for dust laden gas and exit for gas at the top and dust at the bottom.
Type of Preheater:
1. SP - Suspension Preheater
2. ILC-E (In Line Calciner Using Execess air)
3. ILC - Single, twin or 4 String
4. SLC - Separate Line Calciner
5. SLC-I (Separate Line Calciner with inline calciner)
6. SLC-D (Separate Line Calciner with Downdraft)
7. SLC-S
1. The first cyclone Preheater patent is develop on 25-July-1934 by Mr. M Vogel Jorgensen (FLSmith Empolyee).
2. Cylone preheater put in operation in 1951 by Mr F. Muller (KHD)
3. Heat Transfer is in Counter Current and 0.1 mm Limestone takes 0.1 second time at ~ 515 °C.
4. The pressure drop of a cyclone raw mix suspension Preheater is in range of 55-60 mbar.
5. Dust load of exit gas is about 80-115 gm/Kg of clinker, average 10% of clinker weight.
6. Exit gas volume is 1.4-1.5 st.M³/Kg of clinker.
7. 80% of heat Transfer is in Riser duct and 20% Heat transfer in Cyclone. Prove by Mr. Spassky of Soviet Cement Plant.
8. By 330 °C gas temperature is dry the raw material with upto 8.5% of moisture.
9. Preheater retention time upto 50 mtr length is 25 sec (Till Kiln Inlet)
10. Riser duct Gas velocity 20-22 m/sec.
11. Kiln L\D ratio (length by diameter) is appox 14: 1

Thanks sir ❤️🔥

[@sabahathussain1320]

Nise explain

[@houcemeddinechaoua3951]

What could be the main reasons for unstable calcination level in the preheater ? For the record the kiln feed is stable

[@ramcharan6969]

nice video sir...sir what will be the cost of 5 stage ILC calciner in approx.

[@rAmigass]

What is calcinator used for?

[@royalritesh_9207]

Sir preheater ke duct me 90 percentage preheating and cyclon me10 percentage preheating ke jate hae

[@shivbhankushwaha5323]

Riser duct aur culsiner ke bare me Bata digiye

[@vivekkumarjakhotra6143]

what is K-line sir ??

[@ziauddinkhanofficial1794]

Dear sir as I know firstly martial into cyclone no 2 duct then goes to cyclone 1 🌀

[@kaushlendrapratapsingh2603]

Sir, plz cyclone and duct design ke bare me ek video banaye ki usak Kya dimensions rahega.

[@yashmenariya3647]

What is string.

[@sthapa9632]

Sir Can you describe about pressure drop in PH Cyclone its advantages or disadvantages

[@cementpdm]

ok

[@jaffaralikhan974]

Sir how r you.sir gypsum calciner new type gypsum boiler ke vidio send kerna.thanks
