To solve the problems that energy consumed excessively, temperature fluctuated largely in the pyrolysis process and pyrolysis by-products can not be used, a novel heating system was designed for pyrolysis, which used liquefied petroleum gas (LPG) and non-condensable gas (NG) to combust simultaneously. The PLC microcontroller utilized the negative feedback to control the pyrolysis temperature within the required temperature range. The experiment apparatus was built to obtain the heating system's temperature rising curve, product yield and input, consumption energy changes. The results showed that the heating system basically satisfied the pyrolysis conditions. The yield of liquid pyrolysis oil was 58.2 %, which was an energy balance but also the most economical point. At this time, the production of NG could provide thermal energy for the heating system to the utmost extent. The thermal energy balance analysis was carried out, finding that the pyrolysis temperature of 500℃ was an ideal condition, where the combustion gas replacement ratio was 76.2 %. Our studies have provided a new design pattern of the heating system for biomass fast pyrolysis with experiment research.

为了解决能量消耗过多，热解过程中温度波动大，不能使用热解副产物的问题，设计了一种新型的热解加热系统，该系统使用液化石油气（LPG）和不凝性气体（NG）。 ）同时燃烧。PLC微控制器利用负反馈将热解温度控制在所需的温度范围内。建立该实验装置以获得加热系统的温度上升曲线，产品产量和投入量，能耗变化。结果表明，加热系统基本满足热解条件。液体热解油的产率为58.2％，这是能量平衡，也是最经济的点。此时，NG的产生可以最大程度地为加热系统提供热能。进行了热能平衡分析，发现500℃的热解温度是理想的条件，燃烧气体的置换率为76.2％。我们的研究通过实验研究为生物质快速热解加热系统提供了一种新的设计模式。
