Controller for ignition and extinguishing of burner
专利汇可以提供Controller for ignition and extinguishing of burner专利检索，专利查询，专利分析的服务。并且PURPOSE:To reduce use of an auxiliary burner to a minimum and to widen a load control range, by extiguishing the auxiliary burner when it attains to a state of a self combustion range by watching coal quantity/primary air quantity, a state of a flame and a load factor of a crusher. CONSTITUTION:This device is so constituted that an auxiliary burner is extinguished when self combustion becomes possible by a method wherein coal quantity to be fed to a crusher is detected by a coal quantity detector 50, primary air quantity to be supplied to a burner through the crusher is measured by a primary air flow meter 51, which are made into coefficients by a divider 52, a present value of coal/air is compared and judged by a coal/air comparator 53 as to whether it is more than a specified value or not, and in addition to the above states of a pulverized coal burner's flame, mill differential pressure and primary air differential pressure are detected.，下面是Controller for ignition and extinguishing of burner专利的具体信息内容。
