摘要
华能太仓港区煤炭中转码头项目采用新型精细化动力配煤技术,为长江下游沿江电厂提供定制的适合锅炉稳定高效工作的低成本动力配煤。该项目配煤技术方案运用由PLC、高精度电子皮带称和可变立轮活化给料机组成的数字化自动流量闭环控制给煤系统实现精细化实时配煤,并结合堆场取料外运流程使已按设定控制流量汇聚在一条胶带输送机上的各参配煤流在后续的运输过程中自然混匀后装船。这种新型精细化动力配煤技术具有工程投资和运行成本低廉、产品性能实时稳定可控的特点。
A new fine coal blending facility for power generation is constructed in Huaneng coal transfer terminal of Taicang port, which could supply low cost blending coals for boiler of power plant keeping in high- efficiency and stable performance. The closed-loop coal flow control composed of PLC, accurate belt scale and feeder with adjustable eccentric block wheel is adopted in real-time coal blending process of this new facility. The coal blending completed in the shiploading process on belt conveyors of Huaneng coal transfer terminal has outstanding characteristics of lower investment and operation cost, controllable and stable properties of products.
