换热式两段焦炉热工预测

针对目前焦化企业迫切需求解决的能耗高、污染严重等问题，提出换热式两段焦炉的炼焦工艺，其工艺特点 是用换热室取代传统蓄热式焦炉中的蓄热室，并在炉体上部引入干燥预热室，有望实现预热煤炼焦、烟气余热品位对 口高效梯级利用和能源优化配置。通过物料平衡和热平衡计算，对换热式两段焦炉和传统蓄热式焦炉进行能耗分析 对比，预测换热式两段焦炉具有生产效率高、节约能源、改善环境等优点，为焦化工业的发展探讨了一条新的途径。

Thermal Predictions of Heat Exchanged Two-Step Coke Oven

Upon the requirement to solve the problems of high energy-consuming and severe pollution in the coking industry， a recuperative two-zone coke oven and its related coking process were proposed in this paper. The regener- ator in traditional regenerative coke oven was to be replaced by recuperator， and a drying and preheating chamber was to be introduced as the upper part of the oven. The preheated-coal coking、efficient cascade utilization of waste gas heat and optimal allocation of energy resources were to be expected. By mass balance and heat balance calcula- tion， energy consumption of recuperative two-zone coke oven was analyzed and compared with traditional coke oven. It was predicted that the new coke oven would be of high productivity， energy saving and environmental protection. It explored a new way for the development of coking industry.
