Combustion characteristics of biomass are very important to directly utilize as an energy resource. Bamboo was carbonized using a XD-1200N muffle furnace in the nitrogen environment and its combustion characteristics were investigated. Results showed that bamboo-biochars had better combustion characteristics compared to bamboo materials, such as a lower content of moisture and volatiles, a higher energy density, HHV and EHC, a lower H/C and O/C ratios and a shorter TTI. Characteristic peak of bamboo-biochars shifted to higher temperature in thermal decomposition process, indicating a more steady-state burning and a higher combustion efficiency. Bamboo-biochars had a low content of S and N, which was helpful to decrease pollutant emissions. A higher content of K and Na was observed in the ash of bamboo-biochars, resulting in slagging, fouling, corrosion and agglomeration. The data from this research will be very helpful to efficiently design and operate its combustion systems.
生物质的燃烧特性对于直接作为能源利用非常重要。本文使用 XD-1200N 马弗炉在氮气环境下对竹子进行碳化,并研究了其燃烧特性。结果表明,与竹子原料相比,竹炭具有更好的燃烧特性,如较低的水分和挥发分含量、较高的能量密度、高位热值和有效碳氢比、较低的 H/C 和 O/C 比以及较短的着火时间。在热解过程中,竹炭的特征峰向更高的温度移动,表明燃烧更稳定,燃烧效率更高。竹炭中 S 和 N 的含量较低,有助于减少污染物排放。竹炭灰中观察到较高含量的 K 和 Na,这会导致结渣、积灰、腐蚀和团聚。本研究的数据将非常有助于高效设计和运行其燃烧系统。
