| titleOfInvention | Method for calcining novel dry-method cement clinker by brown coal |
| abstract | The invention discloses a method for calcining novel dry-method cement clinker by brown coal, wherein the method comprises that the brown coal is sent to a decomposing furnace as a calcining fuel after crushed and homogenized. Based on characteristics of short combustion time of the decomposing furnace and long combustion time of a rotary kiln, the method of the invention uses brown coal to replace common novel dry-method soft coal as a fuel of the decomposing furnace, and the rotary kiln still uses soft coal or/and anthracite with characteristics of high heating value and long combustion time, wherein the brown coal has characteristics of low heating value, low price, fast flaming speed and short combustion time, and the soft coal has characteristics of high price and long combustion time. The method enables fuel characteristics to accord with different combustion characteristic requirements of the decomposing furnace and the rotary kiln, is in favor of raising a burn-off rate of coal dust and raising a decomposition speed of calcium carbonate, reducing buildups jam of a preheater system, enables a utilization rate of brown coal for producing novel dry-method cement to reach more than 60%, fully utilizes a local coal resource, raises an energy utilization rate, and further reduce a production cost of cement. |
