32 Cemex, Thailand 2 Kilns upgrading to 1200 TPD Client Name: CEMEX Thailand LVT Role: EP Contract for kiln upgrading from 900 TPD and 1200 TPD Project period: Main objective: To increase the plant capacity from 900 to 1,200 TPD

33 Job carried out : Cemex, Thailand 2 Kilns upgrading to 1200 TPD New top stage cyclones Top cyclones preheater will be replaced to the new LVT cyclones (without refractory) for improving the efficiency. It can be improved by installing a cylindrical part at the body of the cyclone. LVT suggest modifying the complete inlet duct section to the top stage cyclones to LVT new design, to avoid the present ducting pinch point at the cyclone inlets, where caking on tendency on the roof has been observed. This will also reduce the pressure drop over the top cyclone stage. The new cylindrical cyclone part will also call for installation of an extra downcomer part.

34 Cemex, Thailand 2 Kilns upgrading to 1200 TPD Modification of the 4 stage cyclone Expand the riser duct after Pre-calciner and Enlarge the riser part of the Pre-calciner A small but not unimportant improvement can be done in the riser part of the calciner. The expansion of the riser part was done on the front side (towards the kiln) and on the right side (seen from the kiln). The start of the riser expansion to the sides has been done nearly horizontal, which has created shelves and areas for possible turbulence resulting in downwards flow and undesired material dropping directly to the kiln (along the walls). New preheater ID Fan & Motor

37 Hanil Cement (Danyang plant ), Korea Kiln No.5upgrading to 4800 TPD Client Name: Hanil Cement (Danyang plant), Korea LVT Role: Engineering Service for kiln upgrading Project period: November 2008 April 2009 Main objective: To increase the kiln capacity from 4,320 to 4,800 TPD and increasing the waste firing upto 20% In year 2008, Hanil cement at Danyang plant would like to upgrade plant capacity and they consult with LVT. After LVT team investigation, the LVT suggest that the Danyang plant can be upgraded to 4800 tpd from 4320 TPD as per the measured during pretest.

38 Hanil Cement (Danyang plant ), Korea Kiln No.5upgrading to 4800 TPD The operation by following the existing main equipment In-Line Calciner (ILC) 5-stage preheater with swirl chamber Kiln 4.57 x 67 m, slope 4 % Kiln drive motor 522 kw Fuller grate cooler (CIS-CFG-RFT) Pillard kiln main burner

39 Hanil Cement (Danyang plant ), Korea Kiln No.5upgrading to 4800 TPD Job carried out : 1) Cyclone Preheater The 4 existing top cyclones will be replaced by completely new LV Cyclones to reduce the pressure loss and to improve the top cyclone efficiency. This will lead to a bit higher pressure drop over the new LVT top stage cyclones. The cyclones are foreseen installed with 114 mm castable

40 Hanil Cement (Danyang plant ), Korea Kiln No.5upgrading to 4800 TPD 2) Extension of the ILC calciner with New TAD inlet and new LVT mixing chamber Hanil is firing approx. 20 % of waste fuel to the calciner. This leads to operational problems and CO formation in the calciner. Hanil possesses at the same time a strong desire to increase the waste firing to 30 %.

41 Hanil Cement (Danyang plant ), Korea Kiln No.5upgrading to 4800 TPD Extension of the ILC calciner LVT therefore suggests extending the existing calciner with a new square duct. The result in the largest possible extension of the calciner gas retention time, which is crucial for the satisfying completion of the combustion of the waste fuel fired in the calciner. The calciner a gas retention time of approx. 4.6 seconds is achieved (at 4800 TPD)

42 Hanil Cement (Danyang plant ), Korea Kiln No.5upgrading to 4800 TPD New TAD inlet and new mixing chamber Installing a new LVT mixing chamber and a modified TAD inlet to the new mixing chamber. The reason is that the existing swirl chamber is much too large (low gas velocity) and do not facilitate a proper mixing of the calciner fuel (waste) and the combustion air. The result is the observed CO problems out of the calciner. With the new LVT mixing chamber we improve the start conditions for the combustion of the calciner fuel (waste), and we are convinced that it shall be possible to increase the %-waste fired from the existing 20 % even at the increased clinker production level to 4800 TPD.

43 Hanil Cement (Danyang plant ), Korea Kiln No.5upgrading to 4800 TPD 3) New LVT material flap gates Installation of new LVT material flap gates to minimize the amount of heat transfer bypass gas flows in the preheater. Any amount of hot gas bypassing the heat transfer process stages leads to an increase in the kiln system heat consumption and to increased temperature profile and hereby to increased pressure drop and increased fan power consumptions 4) Modified inlets to the two bottom stage (C5) cyclones Modification of the inlets to the two cyclone stage number 5 cyclones to minimize dust settlement and build up in these areas.

44 Hanil Cement (Danyang plant ), Korea Kiln No.5upgrading to 4800 TPD 5) Material spreader boxes (distribution boxes) The existing spreader boxes (distribution boxes) in the preheater are suggested replaced by new and more efficient spreader boxes of LVT design
