Job carried out :

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.

Cemex, Thailand


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).

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.

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



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



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 %.



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)



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.



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.



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
