Kotka

On a window in Kotka, a slightly battered mosquito sits silhouetted against a mosaic of water drops, each reflecting spring sky and the crayon colors of nearby buildings.

在芬兰的科特卡，一只嗡嗡叫的蚊子趴在窗户上看五彩斑斓的水滴，每个水滴都呈现出天空的蓝色和附近建筑的颜色。

This is a critical function because the quality of the municipal and industrial waste used to power the Kotka plant varies dramatically, yet the burning process must remain steady and consistent.

由于利用市政和工业的垃圾质量变化性非常大，但是燃烧过程又需要持续和稳定的燃烧，所以这是关键部分。
