非炼焦煤

通过煤质改性提高非炼焦煤在炼焦过程中用量的试验研究炼焦过程中多环芳烃与NOx产生的相关性

Study on Increasing the Usage of Non-coking Coal in Coke-Making by Adding Coal Modifying Additive into Coal Blend EMITTING RELATIVITY OF POLYCYLIC AROMATIC HYDROCARBONS AND NO_x IN COKING

COREX是用非炼焦煤与氧气的熔融还原炼铁法，取代传统的高炉、焦炉、烧结组成的炼铁系统。

COREX ironmaking means that conventional ironmaking system with blast furnace , coke oven and sintering circuit is replaced by melting reduction ironmaking with non-coking coal and oxygen .

COREX流程是目前世界上以非炼焦煤为主要还原剂，能大规模生产铁水的成熟工艺；

At present , the COREX process is the only technology existing on an industrial scale which directly produces hot metal from ore and non-coking coal as reductant ;

COREX熔融还原炼铁工艺采用非炼焦煤直接炼铁，缩短了工艺流程，减轻了炼铁工业对环境的污染，生产过程产生的大量优质煤气可以用于生产热压块。

The COREX process for hot metal has been known as an advanced technology due to the use of non-coke coal which can shorten the production route , greatly lighten pollution of iron making process , and offgas can be used for production of HBI .

型焦技术是合理利用非炼焦煤资源或扩大煤焦煤资源的有效途径，工艺条件对型焦质量影响很大。

The technology of formed cokes is an effective way for making rational use of noncaking coal resources or extending coking coal resources .

本文根据我国拥有丰富高挥发份非炼焦煤资源特点，提出了煤气厂直立式炭化炉应积极使用非炼焦煤制取城市煤气的设想。

Based on rich resources of high volatile non-coking coal in China , this paper proposed the idea about that which non-coking coal is used to manufacture city gas in vertical retort of gas plant .

作者结合自己的试验研究成果和经验，提出高挥发份非炼焦煤用于直立炉须满足的两个工艺指标，即块煤热稳定性和块煤干馏后的落下强度。

The author proposed that high volatile non-coking coal is used in vertical retort and to meet index of two processes , such as : heat steady property of cake coal and falling strength after carbonization of it .
