为了充分利用煤炭,节省资金和能源,长期以来,我们对焦炭、煤块的燃烧做了多次观察、分析和试验。 笔者认为,单用焦炭或煤块作燃料不如和煤粉混合使用效果好。在化铁炉上试验表明,往已燃烧着的炉子加焦炭后,因焦炭本身是冷的,会使炉温降低,需要一段时间预热,靠已燃烧的焦炭把它点燃。点燃后,其温度未达到已燃烧焦炭的温度时,它的放热 In order to make full use of coal and save money and energy, we have done many observations, analyzes and experiments on the burning of coke and coal lumps for a long time. The author believes that the use of coke or coal as a single fuel and coal mixed with good results. Experiments on the hearth show that after the coke is burned, the coke itself is cold, lowering the temperature of the furnace, taking some time to warm up and igniting it with burnt coke. After ignition, its temperature does not reach the temperature of the burnt coke, it's exothermic
