Abstract A variety of biomass materials unique to the Huanghua area of Hebei Province are used as raw materials to make biomass particles. According to the requirements of the national standard, the density, mechanical strength, water content, calorific value, volatile content, ash content and components of different biomass particles were analyzed. The results show that the density of biomass particles is between 1.1 and 1.3 g/cm3, the calorific value of combustion is between 3 500 ~ 5 000 cal/g, which is equivalent to 0.50 ~ 0.71 of the standard coal equivalent, and the volatile content is between 41.5% and 45.3%, ash content is between 0.8% and 4.2 %. Among them, the heat value of pine trees such as Huanghuasong is high, the ash content is low, and the silicon content is high and the ash is loose. The calorific value and ash content of agricultural products such as jujube core are centered, and the alkali metal content is high, and there are some slag forming phenomena. The heat value of wild plants such as reeds is low, the ash content is high, and the content of silicate and alkali metal salts in ash is high, and the ash residue is glassy.
