Application And Research Of Anthracite In Coking

Coke is the main raw materials and fuels in metallurgy、machinery and chemical industry. In recent years, coke tight supply on the International centre and its price has been rising around the word. In this study, combined with China’s abundants of coal resources and a wide range, However, the proportion of coking coal is higher and the proportion of coking coal is lower, resource of coking coal constraints for the country and higher prices, the company of Huaneng coal gasification coking has a higher coking costs, has a lower coke quality and coke breeze waste of resources and environmental pollution, then I did a fully investigation.According to six kinds of coking coal gasification Huaneng provided for each coal industry were analyzed. In 5Kg small coke oven, the basis for the coking temperature transfer research.1. The provision of industrial analytical test coal gasification by Huaneng Coking Company, for this study were coal preparation. More coal to determine the election: BAUER coking coal, fat coal Panjiang, gas coal and Nayong River anthracite, coking and each carried a single test. Tests showed that coking coal, fat coal can be formed relatively high coke strength, the strength of gas coal coke formation is relatively low, the indicator does not meet the three coke, anthracite unable to form coke.2.Obtained by the temperature detection of different coal transfer speed of impact on the coking temperature. Heat transfer rate can be drawn from the impact of coking coal were: coking> Anthracite> gas coal> Fat coal. After the end of the coking process, the impact of coke and coal furnace wall temperature difference in the size of the order of: Coking> Fat coal> gas coal> anthracite.3.Through single factor experiments, each with different coal into coke strength ratio trends influence and find the premise of ensuring secondary metallurgical coke coking coal, fat coal, gas coal and anthracite minimum Blending Ratio with the maximum rates were: coking coal 20%, Fat coal 33%, gas coal 15%, anthracite 34%.4.By orthogonal experiment, obtained by analysis of the impact poor mechanical strength of coke coal for the different indicators M40: fat coal �'anthracite �' coking coal �'gas coal; M10: fat coal�' anthracite �' gas coal �'coking coal. And draw the best ratio in ensuring the secondary metallurgical coke coal each case, namely coking coal: 20%, Fat coal 35% and gas coal 12%, anthracite: 33%.5.And in each case the best ratio of coal coke breeze were added single factor determined in ensuring the secondary metallurgical coke coke breeze in the case of the largest coal can be equipped with the ratio of 2%.
