吉林热电厂200MW机组动态混配煤方案的论证

Discussion of Dynamic Mixing and Proportioning of Coal in Jilin H. P. P.

火力发电厂燃用的天燃煤的质量,不仅影响电厂的经济性,而且直接关系到发电厂设备的安全与稳定运行。对已经建成投产的机组,在无法改变煤源的状况下,如何提高煤质?本文通过在燃用劣质煤中混入一定比例量优质煤的办法,提高入炉煤的发热量,从而改变生产被动局面,取得很大经济效益的实例,论证动态混配煤方案,为燃用劣质煤的电厂,提供了一条改善煤质状况的理想途径。

The quality of as-fired coal in a thermal power plant affects not only the economy, but also the safety and stability of the plant operation. The coal sources of generating sets already in operation are definite: how can the coal quality be improved? In this paper, the example of taking measures to mix a certain ratio of high quality coal into the low-grade coal is discussed, thus to raise the heat value of as-fired coal; from which the passive situation of production was turned round , and much economical advantages gained. Discussion of the scheme of dynamic mixing and proportioning of coal, provides an ideal path of improving coal state for the plants burning low-grade coal
