Title: 600MW generating units of inferior coal combustion stability regulation technology
ABSTRACT
This paper introduces the experience of burning high sulfur and high ash coal in Fa'er 4× 600MW power plant,and research inferior coal combustion stability control technology。When burning the coal that easy coking ,the main method is to use smaller imaginary circle diameter,improving the stiffness of primary air and coal mixture,select small fineness of pulverized coal;When burning the coal with high sulfur,low heat value and low volatile matter,mainly from the controling of primary air speed,choosing the intersection of primary air and secondary air, reasonabler distribution of secondary air,choosing the opportunity of inputing fuel oil。It is very meaningful to thermal power plant that burning the same type of coal。
