The comprehensive investigation of a pyrolysis reactor has been conducted on the basis of thermal engineering design. The gas dynamics, thermodynamic, and psychrometric behaviour of the producer gas have been thoroughly assessed. The pilot-scale reactor has been programmed to operate at the temperature 973 K in the absence of an inert medium. The concentric casing of the heating filament has been used as an external source of energy. The experimental task is divided into two parts: upgradation of biomass and the decomposition of pellets in a developed small-scale pyrolysis unit for the possible gas, char, and pyrolysis oil generation. The fuel upgradation is performed via quasi-static torrefaction of pine pellets using Joule heating in the presence of nitrogen gas. The volumetric gas of nitrogen flowing across the improvised furnace is 0.70 L·min⁻¹. The obtained results are compared with the wood pellets. The unsaturated producer gas has been found to vary accordingly to the following gas equation $p{v}^{0.25}=C$ and $p{v}^{-0.69}=C$ for the processed pine pellets and wood pellets, respectively. A relative increase of 21.00% has been seen while running the reactor with the processed pine pellets. The percentage yield of the pyrolytic oil for the processed pine and wood pellets is 10.48% and 30.00% respectively. The flame temperature and adiabatic flame temperature of the producer gas (processed pine) is lowered by 8.10% and 17.00% respectively. The energy yield of processed pinechar is found to be 122.58% higher than that of wood char.

热解反应器的综合研究是在热工程设计的基础上进行的。已对生成气的气体动力学，热力学和湿热行为进行了全面评估。已将中试规模的反应器编程为在不存在惰性介质的情况下在973 K的温度下运行。加热丝的同心外壳已用作外部能源。实验任务分为两个部分：在开发的小型热解装置中生物质的升级和颗粒的分解，以产生可能的气体，焦炭和热解油。燃料的升级是通过在氮气存在下使用焦耳加热通过松粒的准静态烘烤来进行的。流经简易炉的氮气的体积气体为0.70 L·min^-1。将获得的结果与木质颗粒进行比较。已发现不饱和产生气会根据以下气体方程式变化$p{v}^{0.25}=C$ 和 $p{v}^{-0.69}=C$分别用于加工的松木颗粒和木质颗粒。当反应器与已加工的松粒一起运行时，观察到相对增加21.00％。加工后的松木和木质颗粒的热解油百分率分别为10.48％和30.00％。煤气（经处理的松木）的火焰温度和绝热火焰温度分别降低了8.10％和17.00％。发现加工后的松木的能量产率比木炭高122.58％。
