焦化除尘灰在球团回转窑生产中应用

Applications of Coking Fly Ash in Production with Rotary Kiln of Pellets

通过开展球团回转窑使用焦化除尘灰研究,焦化除尘灰在球团回转窑生产使用的混合煤粉中的配比能够达到15%,回转窑工艺生产顺行,球团质量稳定。同时,解决了焦化除尘灰堆存造成的环境污染问题,为焦化除尘灰有效处理提供了新的途径。焦化除尘灰配入混合煤粉有效降低了燃料成本,降低了球团的生产成本。

The proportion of coking fly ash in mixed pulverized coal used in the production with rotary kiln of pellets could reach 15%,production with rotary kiln process is trouble-free and quality of pellets is stable by studying rotary kiln of pellets with coking fly ash.Moreover,the problem of environmental pollution caused by stockpiling of coking fly ash is solved,which provides a new way for effective treatment of coking fly ash.The fuel cost and production cost of pellets are effectively reduced by adding coking fly ash into mixed pulverized coal.
