During the recovery of heat energy from the cylinder exhaust of diesel engines, the installation can greatly reduce noise pollution and mostly eliminate exhaust lampblack.

当它对柴油发动机汽缸排气余热回收时，大大地降低了噪声，且排气中油烟亦基本消除。

The turbines burn only 40 percent of the natural gas they would if they were fueled by natural gas alone, and better heat recovery technology would lower that figure to 30 percent.

这些涡轮机只需要燃烧原本需要量的40%即可，而更先进的热能回收技术可以把这个值降低到 30%。

The ground loop itself is used to provide the source and offers an extremely efficient method of heat recovery.

地面循环本身是用来提供源，并提供一个非常有效的热回收方法。

The technology in question is KERS (kinetic energy recovery system) for capturing and storing the car's braking energy instead of wasting it as heat.
