As for the combustion method, a composite combustion technology combined suspension combustion of wood powder with layer combustion of coal on the chain furnace is suggested.
在燃烧方式上，尽量考虑运用木材粉悬浮燃烧和链条炉上煤层燃的复合燃烧技术。
Coal fire is a dynamic process caused by spontaneous combustion of the coal layer in various directions, accompanied by the sensible thermal field variation both in time and in space.
煤层自燃是一个动态变化的过程，随着自燃向不同方向扩大或缩小，其热场随着燃烧过程而发生空间变化。
The results prove that the movable heat insulate layer has obvious effects on improving the temperature profile in furnace and combustion efficiency of coal fired boiler at low load.
试验表明：可调卫燃带对改善锅炉低负荷时炉内温度分布及提高燃烧效率具有十分明显的效果。
