<p>PCT No. PCT/DK95/00160 Sec. 371 Date Sep. 20, 1996 Sec. 102(e) Date Sep. 20, 1996 PCT Filed Apr. 18, 1995 PCT Pub. No. WO95/29138 PCT Pub. Date Nov. 2, 1995A method and apparatus for controlling the temperature in a kiln in which cement clinker is manufactured. The temperature is controlled by controlling the fuel rate to the kiln. The fuel rate is adjusted according to a calculation that is made of the sulphur evaporation in the kiln, thereby obtaining a measure of the instantaneous temperature in the burning zone. The evaporation factor is calculated on the basis of measurements of the sulphur content in the cyclone material which passes to the kiln or a measurement of the sulphur content in the exit gases out of the kiln.</p> |
