Partial run customarily called partial furnace, by definition, the "partial" refers to all areas of the material layer temperature
-
differences are the following phenomenon: some half cold, half hot; some part of the cold region, part of the normal state; some
-
part of the district heating, part of the region the normal state; plenty hot center, edge cold; plenty of edge heat, central cold;
-
plenty of hot center and periphery, the intermediate ring with cold; plenty of cold center and periphery, the intermediate ring with
-
thermal. Most of bias arises from the following types of furnace reasons:
-
(1) Since the ash body caused by congenital defects, often in the big gray knife before the fire layer on the move, big gray knife
-
drop occurs after the fire floor, the situation is severe, the side causing the surface sparkle, causing the other side of the fire
-
layer down bottom.
-
(2) of the air flow and increase the performance of the coal body suited, in a small flow, the temperature tends to lower edge, and
-
the center temperature is high. In the large flow is often caused by edge temperature is high.
-
(3) Since the particle size can also cause partial coal furnaces, coal when using smaller particles, the center stoker more, the
-
center temperature is low, the edge temperature. When the coal particle size is too large, the resulting center of high temperature,
-
low temperature edges.
-
(4) Since the slag and clinker, affecting up that part of the material layer, resulting in the furnace side.
-
(5) Since the slag properly, high-speed large ash content of the slag, resulting in a large gray area after local fire knife off
-
the bottom layer and partial furnaces.
