新的气化装置和技术目前正在测试中，但它们都面临着主要相同的缺点，例如去除发生炉气体中的各种污染物或堵塞材料路径。这项工作是面向开发一个新的模型的非氧化性热解步骤的气化过程的一部分，更广泛的研究进行的整体气化木材废物。间歇式反应器是通过节点建模，一种广泛用于简单的传热过程的技术。除了间歇式反应器内的热传输，该模型使用了一个简单而通用的通用化学和简化的传质原理。从建模的热数据进行了比较，从实验批式热解反应器使用木屑和切屑的数据。关于热现象的实验和理论结果是一致的。
New gasification installations and techniques are being tested today but they all struggle with mainly the same drawbacks such as removal of various pollutants in the producer gas or clogging of material pathways. This work is oriented on developing a new model for the non-oxidative pyrolysis step of a gasification process as a part of a wider research conducted on the overall gasification of wood waste. A batch reactor is modelled by means of nodal modelling, a technique widely used for simple heat transfer processes. Additionally to the heat transport inside the batch reactor the model uses a simple and versatile generic chemistry and simplified mass transfer principles. Thermal data from modelling is compared with data obtained from an experimental batch pyrolysis reactor using wood sawdust and cutter shavings. Experimental and theoretical results regarding thermal phenomena are in good agreement.
