Specialized Tools · Kiln · No. 03

Is your kiln working in the band of its type?

Free lime jumps, the coating falls, the burning zone shell runs hot and the refractory bill grows. The flame, the kiln speed and the load decide it, yet they are rarely checked together, and the operator changes one thing at a time without knowing where the kiln sits in its band.

What it savesKeeps the burning zone and the flame where the clinker is made, not the shell.

How this file helps

Find out if it is happening to you, how much it costs, and what to correct.

1Find outResidence time, filling and loads, graded against kilns of the same type.
2MeasureThe flame of the main burner: primary air, tip velocity and momentum.
3CorrectToday's condition from O2, burning zone and back end, with the actions in order.

What it gives you

The kiln, graded against its own type.

Questions

Before you buy

Can I see it before I buy?

Yes. The sample report shows the whole first sheet of the file, worked on a demonstration plant: every result, the charts and what to do first.

Does it need the internet or macros?

No. It works on Excel 2013 or later, on Windows or Mac, with no macros and no connection. Nothing to install.

Can I use it for several kilns?

Yes. Save one copy per kiln and per test. The file is yours to use for as long as you like.

What is the What-if column?

Type a new figure beside today's and see every result change, before anything is changed in the plant.

Who may use my copy?

One engineer or one plant. Your name is written on every sheet.

How do I pay?

Press Buy. We reply on WhatsApp and by email with the bank details. When the payment arrives, your copy is ready to download from this page.

Kiln Heat Balance, a worked example
Kiln · No. 01
Kiln Heat Balance

Where does the heat of your kiln go?

The heat crept up 20 kcal/kg this month and nobody can say where it went. On a 5,000 t kiln that is about 17 t of coal a day, burnt for nothing.

What it savesFinds the kilocalories above target, and puts a daily cost on them.

  • The heat of every fuel, main burner and calciner, per kg of clinker
  • The full balance in and out: preheater gas, cooler exhaust, clinker, radiation

Kiln Gas, False Air, Fans and Stack, a worked example
Kiln · No. 02
Kiln Gas, False Air, Fans and Stack

Is your ID fan moving kiln gas, or leaked air?

The ID fan is at its limit and the kiln cannot take more feed. Very often the fan is pulling air that leaked in through doors, flaps and joints, not kiln gas.

What it savesTurns the air leaking into the tower back into capacity for feed.

  • Excess air at the kiln inlet, the calciner outlet and the preheater exit
  • The false air between them, and what one point of O2 costs a day

Raw Mix, Clinker and Volatile Cycles, a worked example
Kiln · No. 04
Raw Mix, Clinker and Volatile Cycles

How much more chlorine will your kiln take before it blocks?

The lowest cyclone blocks again and the kiln stops. Chlorine and sulfur circulate unseen until they condense, and every ton of new alternative fuel adds to them.

What it savesTells how much alternative fuel the chemistry will take, before the cyclones find out.

  • LSF, moduli and the clinker phases from the kiln feed
  • The heat of clinker formation for the heat balance
