结焦时间
coking time
jiejiao shijlan结焦时间(coking time)煤料装入焦炉炭化室至焦饼成熟的时间。在这段时间内,装炉煤经过焦炉炭化室内结焦过程转变成焦炭。在炼焦生产中,一般把装煤时平煤杆伸入炭化室至推焦时推焦杆头接触焦饼之间的时间间隔定为结焦时间。结焦时间越短,焦炉的焦炭生产能力就越大。结焦时间的长短,与炭化室宽度、炭化室墙厚度、砌筑炭化室墙的耐火材料及其导热系数、两侧燃烧室的温度、装炉煤水分和堆积密度等有关。由于耐火材料的荷重软化温度限制了燃烧室温度的提高,因此,结焦时间的缩短也是有限度的。乌克兰煤炭化学研究所提出,当燃烧室温度一定时,炭化室宽度与结焦时间存在以下关系: ‘,,。,、,l架 几、乙:)式中t,、t:为结焦时间,h;bl、b:为炭化室平均宽度,~;Ts、八分别为燃烧室温度和焦饼中心最高温度,℃。通常,室式焦炉在顶装煤条件下,当炭化室墙厚度为90~100mm、炭化室宽度为300一350znm、标准立火道温度为1300一1340℃时,结焦时间为10~14h。当炭化室墙厚度为100~IO5mm、炭化室宽度为400一450mm、标准立火道温度为1300一1350℃时,结焦时间为巧一17h。为了提高焦炉生产能力,在设计焦炉时,可以采取的缩短结焦时间的措施有,(l)减薄炭化室墙;(2)采用导热系数高、荷重软化温度高的耐火材料砌筑炭化室墙;(3)采取煤干燥工艺或煤预热工艺对装炉煤进行炉外预处理。 (葛茂弟李哲浩)
