Biomass, which is a renewable resource, is regarded as an essential energy source due to its accessibility and abundance. In this study, the gasification of wood-based biomass wastes from the medium density fiberboard (MDF) facility was carried out and investigated utilizing an updraft fixed bed gasifier. The feeding capacity of the upstream gasifier is 2100 kg/h. MDF wastes are loaded into the system with feeding capacities of 1500, 1750 and 2100 kg/h. As a reference, the system has also been tested with oak wood chips at a maximum rate of 2100 kg/h. Produced syngas production rate to biomass waste is approximately 2.5 Nm/kg. The measured gas compositions are CO, CO, CH, H, O and N. Test results with 2100 kg/hMDF wastes have similar gas composition compared to the test results with oak wood chips. The quality of the syngas produced by gasification is directly related to the fuel. It has been observed that the efficiency of the gasification process can be directly or indirectly impacted by the properties of the fuel, such as the moisture content, chemical compositions, and size. The temperature of the produced gas is approximately 430 °C, and it isdirectly combusted with tars and soot it contains to ensure that no chemical energy is lost. The thermal gasification system converts approximately 88% by weight of MDF residue to syngas. The calorific value of produced syngas is obtained between 6.0 and 7.0 MJ/Nm. The hot syngas containing tars produced from the gasifier was directly burned in the thermal oil heater retrofitted to vortex syngas burner to recover thermal energy, which was then utilized in the production of energy via an ORC turbine. The thermal oil heater has a thermal capacity of 7MWh and the power generation capacity of the ORC turbine is 955 kW of electricity.
生物质是一种可再生资源，因其易得性和丰富性而被视为重要的能源。本研究利用上吸式固定床气化炉对中密度纤维板（MDF）工厂的木质生物质废料进行气化，并进行了研究。上游气化炉的进料能力为 2100kg/h。MDF 废料以 1500、1750 和 2100kg/h 的进料能力装入系统。作为参考，系统还以最大速率 2100kg/h 用橡木木屑进行了测试。生物质废料的产合成气速率约为 2.5Nm/kg。测量的气体组成是 CO、CO、CH、H、O 和 N。以 2100kg/h 的 MDF 废料进行的测试结果与以橡木木屑进行的测试结果具有相似的气体组成。气化产生的合成气的质量直接与燃料有关。已经观察到，气化过程的效率可以直接或间接地受到燃料性质的影响，例如水分含量、化学成分和大小。产生的气体温度约为 430°C，其中所含的焦油和烟尘直接燃烧，以确保没有化学能损失。热气化系统将约 88%重量的 MDF 残渣转化为合成气。产生的合成气的热值在 6.0 和 7.0MJ/Nm 之间。从气化炉中直接产生的含有焦油的热合成气在改装的涡流合成气燃烧器中的热载热油加热器中燃烧，以回收热能，然后通过 ORC 涡轮机用于能源生产。热载热油加热器的热容量为 7MWh，ORC 涡轮机的发电能力为 955kW 的电力。
