smokestack

At the other end of Shenzhen from Longgang, no smoke is visible from the towering smokestack of the Baoan incinerator, built by a company owned by the municipal government.

深圳龙岗的另一端是宝安垃圾焚烧厂，它由政府所有的一家公司建造，它的烟囱里几乎没有任何可视烟雾排出。

Today, the fly ash produced by coal-fired power plants brims with cenospheres, but they are largely trapped by pollution-control equipment before they escape the smokestack.

如今，由煤炭发电厂所排放的煤灰中充斥着许多小“煤胞”，但大部分在逃离工厂的大烟囱前就让污染控制设备给过滤了。

So for months I have watched a gray plume rise heroically from the smokestack’s summit, disappearing into the gray muckosphere.

连着好几个月，偶都眼巴巴地看着一股灰色的烟柱从烟囱顶上冒出，直冲云霄，最终消失在灰蒙蒙的烂大气里。
