利用土窑、以煤渣作为燃料进行内燃烧制青砖,最近在江苏省南通专区长河砖瓦厂进行首次试点,已经获得成功。共生产了14余万块青砖,收到了显著效果。一、成品质量——经多次检验,平均标号超过100~#,比原来平均标号75~#超过25%以上;砖的一等品率由过去86%提高到97%。二、煤耗——过去烧一万块青砖要3.5—4.0吨煤,现在只要1.53吨,煤耗降低50%以上。三、产量——过去焙烧一窑时间要七天以上(168小时以上),现在只需要90—93小 The use of earth kiln and coal slag as fuel for internal combustion of blue bricks was recently carried out at the Changhe Brickyard in Nantong Prefecture, Jiangsu Province. A total of more than 140,000 green bricks were produced, which have achieved remarkable results. First, the quality of finished products - After repeated inspections, the average number of labels exceeds 100~#, which is more than 25% more than the original average number 75~#; the first grade of brick products has increased from the previous 86% to 97%. Second, coal consumption - in the past to burn 10,000 green bricks to 3.5 - 4.0 tons of coal, now as long as 1.53 tons, coal consumption decreased by more than 50%. Third, the output - in the past to roast a kiln to more than seven days (168 hours or more), now only need 90-93 small
