Since the thermal Power Plants in the Kyushu Districts are obliged to use low quality coal for fuel, they have no alternative but to utilize combustion of pulverized coal. The Unit System Tube Mill is a low costing Pulveruzer, but this system has its difficulties with automatic coal feeding. The reason being that as the feed control is carried out by interlinking the draft of the exhauster which blows the pulverized coal into the furnace with the feed rate of the coal feeder, after operation over a long period，excessive quantities of coal accumulates within the mill causing Mill-over or shortage of pulverized coal comes about decreasing the load of the Power Plant. With such difficulties constantly happening, perfect automatic combustion cannot be obtained. These defects can be corrected by disconnecting the interlink between the coal feeder and the exhauster, and controlling the feed rate of the coal feeder so that a fixed quantity of coal is constantly retained within the Tube Mill. Since a detector is necessary to determine the quantity of coal retained in the Tube Mill, the Author has invented and developed an Electro-acoustic Mill Level Meter which is quick responding and enables the operator to accurately detect the quantity of coal retained within the Mill. Recently the Unit System Tube Mill coal feeding system of the No. 2 Minato Power Plant of the Kyushu Power Company was completely switched to automatic operation by the use of this invention. Following this, the same automatic coal feeding system was installed at the Ainoura Power Plant which brought about excellent operating results. This thesis reports on the outline of this Invention.
