基本原理
BASIC PRINCIPLE
热解是指将有机物在无氧或缺氧状态下进行加热蒸馏，使有机污染产生裂解，经冷凝后形成各种新的气体、液体和固体，从中提出燃料油、油脂和燃料气的过程。
Pyrolysis refers to the process of heating and distilling organic matter in the absence of oxygen or such a limited supply, causing organic pollution to produce pyrolysis and forming various new gases, liquids and solids after condensation, from which fuel oil, grease and fuel gas are put forward.
