この発明は成型炭槽からベルトコンベアを介して石炭塔
に供給される成型炭の粉化防止方法に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for preventing pulverization of molded coal supplied from a molded coal tank to a coal tower via a belt conveyor.
（従来の技術及び発明が解決しようとする課題）成型炭

継いで送給されるが、ベルトコンベアのジャンクション
にて落下する際に、その落下の衝撃により成型炭がかな
りの割合で粉化していた。(Prior art and problems to be solved by the invention) Molded coal is mixed with blended coal and sent to the coal tower via a belt conveyor, but when it falls at the junction of the belt conveyor, the A considerable proportion of the briquette coal was pulverized by the impact.
この発明は、かかる問題点を解決するためになされたも
ので、成型炭の粉化率を減少させることを可能にした成
型炭の粉化防止方法を得ることを目的とする。The present invention was made to solve this problem, and an object of the present invention is to provide a method for preventing pulverization of briquette coal, which makes it possible to reduce the pulverization rate of molten coal.
（課題を解決するための手段）
この発明に係る成型炭の粉化防止方法は、成型炭払出し

更に配合炭（２３）でコーテングされる。In the equipment configured as above 15, the molten coal tank (
Molded coal discharged from 1) is transferred to a belt conveyor (3)
from there to the Bell 1 conveyor (6). then,
At the junction of Bell 1 conveyors (3) and (6), tar slag from tanks 2) is sprayed onto the briquette coal from below by a spray gun (4). After that, the blending point
is transferred onto the belt conveyor (6) by the belt conveyor (5). For this reason, briquette coal that has been mixed with tar slag is mixed with tar slag. is attached,
Furthermore, it is coated with a coal blend (23).

従って、ベルトコンベア（６）以降の移送に際しては、
成型炭が２重のコーティングされているので、これらの
コーティングがクツションとなり、成型炭の形状が崩れ

いる。Figure 2 (A) shows conventional briquette coal (21), and Figure 2 (B) shows briquette coal (21), tar slag (22) and blended coal (23).
This is the briquette coal (20) of this example which was subjected to the following process.A comparison of these in terms of shutter strength is as follows. The numbers below indicate the original shape retention rate.
