In this case, the pulverized coal conveying pipe 7 coming out from the pulverized coal feeder 6''
Since there is only one burner 8°, it is necessary to turn on and extinguish the four burners at the same time. However, if the four burners are ignited at the same time, the change in the amount of fuel supplied is too large.

料システムに応用できるものである。The present invention is a device for cutting out pulverized coal from the storage bin in a boiler that uses all tangential burners, in which coal, oil, coke, etc. is stored in a -H storage bin and then supplied to the burner for combustion.
A pulverized coal feeder capable of supplying fixed amounts of pulverized coal 10,000 times is installed below the storage bin, and an air tray damper for conveying 20,000 times is installed in the air pipe leading to the pulverized coal feeder, facing each other. The solid fuel supply system is characterized by bare burner operation and paired point extinguishing of opposing burners. The present invention aims to provide a solid fuel supply system that can be minimized and can be applied to the fuel system of a boiler that completely burns petroleum coke or coal (anthracite).

FIG. 2 shows a schematic diagram of an embodiment of the solid fuel supply device of the present invention. The fine powder of fuel pulverized in the mill passes through one pulverized coal pipe by a conveying gas, enters a cyclone ZVc, is separated by the cyclone, and enters a storage bin 5Vc.
また微粉會分離された搬送用ガスはサイクロン出口排ガ
ス管５を通り排風機４ｔ−介して大気等へ排出される。The finely separated conveying gas passes through the cyclone outlet exhaust gas pipe 5 and is discharged to the atmosphere through the exhaust fan 4t.

17. Transported to 18.19 - In this case, flow meter 121
11 and distribution dampers 9 and 10 to form a primary air pipe 15'.
The conveying air passing through the tube is divided into two parts.
