Embodiment Construction

[0037] according to figure 2 The cement production equipment generally includes, for example, a preheating zone 1 composed of multi-stage suspension heat exchangers, a calcination zone 2 and a sintering zone 3 in the form of a cylindrical rotary kiln, and a displaceable grid cooler for example. Subsequent cooling zone 4. The exhaust gases of the sintering zone 3 flow continuously through the calcining zone 2 and the pre-heating zone 1, and the raw material flows countercurrently to the pre-charging zone 1 and subsequent calcination in a manner known per se, before the pre-calcined material is burned in the sintering zone 3 Belt 2 provides the exhaust. The sintering zone has at least one burner 5 with adjustable momentum.

[0038] The sintering belt 3 is operated with a burner with adjustable momentum, so that the shape, size and / or temperature of the flame can be adjusted by adjusting the momentum.

[0039] In the example shown, the calcining zone 2 is formed by an oblique...

Abstract

In the method according to the invention for operating a cement plant, the raw meal is preheated in a preheating zone, the preheated material is precalcined in a calcining zone and the precalcined material is finally sintered in a sintering zone. The cement plant is operated in such a manner that the precalcined material which is supplied to the sintering zone has an SO3 concentration of at least 5.5% by mass and a CaSO4 proportion of at least 75%, preferably 90%, of the total salt content.

Description

technical field [0001] The present invention relates to a cement manufacturing plant and a method of operating a cement manufacturing plant. Background technique [0002] In the production of cement clinker, the raw materials must first be preheated, then pre-calcined, and finally fired in the furnace. The current combustion process takes place in the sintering zone of the furnace, where the material is heated to a temperature of 1400C° to 1500C°. [0003] German Patent No. DE69806183 relates to a method of producing cement clinker by sulfur-rich fuel. The oxygen concentration at the inlet of the combustion furnace is increased from 4.5% to 5.5%, thereby increasing the temperature of calcium sulfate decomposition and greatly exceeding the sintering temperature. so that calcium sulfate (CaSO 4 ) become an ingredient of the finished product, rather than decomposing into gas and leaving deposits in the combustion furnace, preheating furnace and preheating cyclone. [0004] S...
