问题问答题计算题

矿批重为14.0吨，理论批铁量为7.90吨，湿焦负荷为3.5吨/吨，焦碳水分为10%，喷煤8.0吨/小时，料速为每小时8批料，炉温为0.70%，若料速不变，炉温降至0.50%，焦量不变，每小时应喷煤多少？综合负荷应为多少？

答案

参考答案：

湿焦批重=14÷3.5=4.0吨

炉温下降0.1%，焦比减少4～6公斤/吨，取5公斤/吨。

炉温由0.70%下降至0.50%，则焦比减少10公斤/吨。

①则焦碳量=7.90×10=79公斤折算成煤粉=79÷0.7=113公斤折算成每小时煤量=113×8=904公斤

则每小时应喷煤=8.0－0.904≈7.1吨

综合负荷=14÷（4×（1－0.1）+7.1÷8×0.7）=3.317吨/吨

②炉温为0.70%时综合焦比=（4.0×（1－0.1）+8.0÷8×0.7）÷7.90=544公斤/吨

设炉温下降到0.50%需每小时喷煤X吨

炉温下降到0.50%时综合焦比=（544－10）÷1000=（4.0×（1－0.1）+（X÷8）×0.7）÷7.90

得X≈7.1吨

     We see many animals, like rabbits, bees, dogs, birds, sheep but do you know    1   these
animals say things? First, let's see a rabbit. When a rabbit sees something     2 , it runs away
at once. When it runs, its tail moves up and    3   . When others see this, they run   4   . Many
other animals use this kind of    5   . When a bee finds some food, it goes back to its home. It
cannot tell     6 bees where the food is by speaking    7    them, but it does a little dance in
the air. This may tell other bees     8    the food is. Some animals say things by making sounds
(声音) like a man    9    . A dog barks when a stranger (陌生人) comes near. Some birds can
make several (几种)    10   sounds, each with its own meaning. In a word, every animal has
