Combustion Characteristics, Kinetics, SO2 and NO Release of Low-Grade Biomass Materials and Briquettes

The influence of the briquetting process on SO2 and NO release characteristics, combustion properties kinetic characteristics during biomass was investigated. Two (Wheat straw Tree bulk) two obtained briquettes were analysed. helps to prevent NO. experimental results show that once is made into a briquette, when reaction temperature 900 ∘C, sulphur ratio for TB reduced from 34.7% 4.3% WS 12.4% 1.6%. When increases 1000 73.4% 30.4%, it 58.4% 10.2%. SEM micrographs compact structure TB-Briquette WS-Briquette reduce rate combustion. thermogravimetry confirmed performance best, while worst. According Coats-Redfern method, fitting performed at segments 250 ∘C 550 correlation coefficient degree above 0.99. effective collision much higher than other briquettes. Compared BR-1 BR-2, trying mix with make compound briquette can enhance TB-Briquette. may guide upgrading technology benefit efficient application
