Internally circulating fluidized beds have been applied to municipal waste incineration for power, these beds 'combustion velocity, burn-off rate and pollution control are better than chain furnace or bubble beds. 内循环流化床已应用于城市生活垃圾的焚烧制能,其燃烧速度、燃尽率及污染物排放优于传统的链条炉或鼓泡床。
The results show that the increase in burn-off rate has improved the hardness distribution through the joint and the toughness of weld. 结果表明:增大变形速率可使热影响区变窄,近缝区晶粒得到细化,并可改善接头的硬度分布状况和焊缝的韧性;
By means of measuring the carbon content of the area near the weld, the effect of burn-off rate on the highest heating temperature of friction welding has also been investigated. 本文通过测试异种金属焊缝界面近区碳浓度的分布,探讨了变形速率对摩擦焊最高加热温度的影响,增加变形速率可使摩擦界面的最高加热温度下降。
After the addition of combustion-supporting agent, the original microcosmic structure of coke is broken, thus not only increases the combustion rate, but also increases the burn-off rate of the coke. 加入了助燃剂后,焦炭原有的微观形态被破坏,这不仅提高了焦炭的燃烧速率,而且也增加了焦炭的燃尽率。
The Burn-off Rate of Low Grade Fuel and the Burn Patterns 劣质燃料的燃烬程度及其燃烬方式
The results indicate that the ICFB may realize the separation and circulation of particles, prolong the particle residence time, increase the burn-off rate and combustion efficiency. 结果表明,内循环流化床能实现炉内分离和循环,延长颗粒在炉内停留时间,提高颗粒燃尽度和燃烧效率。
Correlated curves of burn-off rate and time corrected by transfer function were fitted with shrinking sphere mechanism, shrinking cylinder mechanism or chemical reaction with reaction order. The most suitable burning model can be decided by the correlation coefficient. 通过传递函数修正后的燃尽率与时间的关系曲线与收缩核模型、收缩圆柱体模型、化学反应级数等模型进行拟合,通过相关系数来选取最合适的燃烧模型。
Influence of Particles 'Lingering Time on the Burn-off Rate of Fujian Anthracite in CFB Boilers 颗粒停留时间对福建无烟煤在CFB锅炉中燃尽的影响
Combustion of micro-pulverised coal has not only the function of decreasing NOX emission, but also represents some combustion characteristics such as low ignition temperature, high burn-off rate, reduction or removal of settling and slag-off made of fly ash on heating surface in furnace. 超细煤粉燃烧不仅有降低NOx排放的作用,在燃烧特性方面也表现出着火温度低、燃尽率高、减弱或消除飞灰在炉内受热面上的沉积与结渣等特点。
