为完成“七五”计划期间,“建材工业发展纲要”和“粘土砖工业七五技术发展纲要”赋予粘土砖工业的技术改造任务,推动整个粘土砖工业的技术进步和不断提高企业的综合效益。现对粘土砖工业的节能途径加以综述。一、发展空心砖空心砖一般要比实心砖耗煤低10—15％,且耗煤随孔洞率增加而减低。有关资料介绍,孔洞率每增加10％,燃料消耗平均降低12—13千克。据测算,我国县以上的砖厂的50％、乡
In order to complete the “Seventh Five-Year Plan” period, the “Outline for the Development of the Building Materials Industry” and the “Outline for the Development of the Clay Brick Industry’s Seventh Five-Year Plan” have given the task of technological transformation of the clay brick industry, promoted the technological progress of the whole clay brick industry and continuously improved the comprehensive benefits of the enterprise. . The current review of the energy-saving approach of the clay brick industry is summarized. First, the development of hollow brick hollow brick is generally 10-15% lower than that of solid brick, and the consumption of coal decreases with the increase of hole rate. According to relevant data, the fuel consumption is reduced by an average of 12-13 kilograms for every 10% increase in the hole rate. According to estimates, 50% of the brick factories in the county above our country
