摘要： In order to create a calcinator preceding the rotary tubular kiln and equipped with secondary firings in which inert fuels that are difficult to ignite or, respectively, difficult to burn (secondary fuels) can be beneficially disposed of by burning for the purpose of calcination of the cement raw meal and a complete burn-out of CO gas strands and other fuel constituents, as well as an exhaust gas with low Nox, are nonetheless assured for cement clinker production lines, the tertiary air channel in the region of the calcination unit is fashioned as a combustion chamber that expands the channel cross-section and through which the suspension flows from bottom to top. Tertiary air having a torsion component as well as an easily ignitable fuel is centrally introduced at the lower end of the combustion chamber, whereby a high-temperature zone that extends centrally from bottom to top and has a hot core flame proceeds from this burning location. An inert fuel that is difficult to ignite or, respectively, difficult to burn (secondary fuel) is introduced into the high-temperature zone and is burned and, thus, is usefully disposed of for the purpose of calcining the raw meal.

摘要： A method for the thermal treatment of mineral raw materials containing calcium carbonate and similar carbonates, particularly for the production of calcined products such as burnt lime, cement, magnesite, dolomite or the like wherein the raw material carriers of the calcium or other carbonate constituents are supplied to the calcining unit with a particle size of from 1 mm to 25 mm. The calcareous constituents are preferably supplied to the calcining unit with a particle size from 1 mm to 4 mm. To achieve this condition, the raw material containing the calcareous constituents is preferably pre-crushed to a particle size below 200 mm and pre-homogenized. It is then supplied to a drying comminution system connected to the calcining unit at the gas side and is suspended therein in direct heat exchange relationship with the gases. The material is preferably processed by means of single-stage crushing and grading to form the appropriate particle size. The upper limit of the grain size is determined by the amount of free lime content or of the ignition loss of the calcined product to the extent that the limit is lowered with a high free lime content or a high ignition loss.

摘要： A method and apparatus for the thermal treatment of mineral raw materials for the manufacture of cement clinker wherein the raw materials are separately preheated and at least partially calcined in separate first and second preheating systems. One of the systems is charged with a mixture of raw materials and fuel, usually a low-grade fuel, to produce calcined meal and exhaust gases. The exhaust gases are passed from the first preheating system into the second preheating system to aid in preheating and calcining the raw materials therein. The calcined meals from both the first and second preheating systems are jointly introduced into a burning system to form cement clinker which is then cooled in the usual way. Additionally, exhaust gases from the burning system and from the cooler can be passed into the second preheating system for preheating and calcining the raw materials.

摘要： A method and apparatus for burning fine grained products, such as raw cement meal, wherein the product is preheated in a preheating stage, calcined in a calcining stage, and is burned into clinker in a clinker stage followed by cooling in a cooling stage. The heating of the largely calcined product in the temperature range of about 900.degree. C. to the beginning of alite formation which occurs at approximately 1250.degree. C. is carried out under the fastest possible temperature rise conditions and the clinker reaction is carried out in concurrent flow with the gas stream in the burning stage. The clinker is then graded into a coarse grained fraction and a fine grained fraction which are then cooled in separate coolers after separation from the gas stream.

摘要： A burner for introducing a suspension of solid fuel particles into a combustion chamber which includes a tubular conduit arranged to receive the suspension therethrough, and flow diverting means positioned at the discharge end of the conduit, and subdividing the cross section of the discharge end into a plurality of discharge openings. The burner may include a centrally disposed conduit which is coaxial with and surrounded by the tubular conduit, and an outer conduit surrounding the tubular conduit and coaxial therewith. The flow diverting means can be positioned at various positions between the respective conduits, to create a turbulent suspension of particles in the primary air stream, creating an aspirating effect for drawing secondary air into the burner along with the turbulent suspension of solid fuel particles.

摘要： Method and apparatus for the thermal treatment of finely divided material for the calcination of cement wherein the material is preheated in a multi-stage heat exchanger and later passed to a calcining furnace. The material is partly deacidified in a pre-calcination zone before entering the sintering furnace where further calcining and sintering of the material is completed. A portion of the feed material is treated with rapidly oxidizing fuel components in a pre-calcination zone in a first stage and with more slowly oxidizing fuel components in a second stage, the more slowly oxidizing fuel components being a mixture of relatively fine granulated fuel particles of substantially uniform size and larger particles of briquetted or coarsely broken fuel.
