求翻译：当料层足够厚，而温度降低时，可加快给煤机的转速，维持1~2分钟后就立即恢复到原转速，稍等2~3分钟看看炉温有否上升，一次不行，可二次，三次，每加一次，一定要稍等一下，观察炉温是否上升，如上升，说明给煤量不足，用此法控制炉温较为有效。是什么意思？

When the material layer is thick enough, the temperature decreases, it can accelerate the speed of coal feeder to maintain 1 to 2 minutes immediately after the return to the original speed, wait 2 to 3 minutes to see whether the furnace temperature rise, one not, may twice, three times, each additio

When the material level enough is thick, when temperature drop, may speed up the stoker the rotational speed, after maintains 1~2 minutes on to restore immediately to the original rotational speed, waits a bit 2~3 minutes to have a look the furnace temperature whether or not the rise, a time is not

Dang material layer enough thick, and temperature reduced Shi, may speed up to coal machine of speed, maintained 1-2 minutes Hou on immediately recovery to original speed, slightly, 2-3 minutes look at temperature has whether rose, once no, may II times, three times, each plus once, must to slightly
