摘要
以玉米秸秆粒度、含水率、成型压力、压缩时间和超声波电源功率为因素,采用单因素试验研究了成型参数对成型燃料抗渗水性和吸湿性的变化规律。结果表明,随着玉米秸秆粒度的增加抗渗水性略有增加,最高为57.2%;含水率在6%时抗渗水性为77.7%,8%~14%时抗渗水性基本相同,约为50%;而成型压力、压缩时间和超声波电源功率对燃料的抗渗水性影响较大,成型燃料的抗渗水性最低约为44%。压缩时间和超声波电源功率增加吸湿率先快速降低,当压缩时间超过90 s或超声波电源功率超过80%时燃料部分炭化破碎,导致吸湿率有所增加;玉米秸秆粒度、成型压力和8%~14%含水率对吸湿率的影响较小。
Based on the factors of corn straw size,moisture content,molding pressure,compression time and ultrasonic power supply,influence of molding parameters on water resistance and hygroscopicity of biomass briquette fuel was studied by single factor experiment.The results showed that water resistance of biomass briquette fuel increased slightly with the increase of corn stalk size,and the maximum value was 57.2%.The water resistance was 77.7%when the moisture content of corn stalk at 6%,and it was about 50%between 8%and 14%.However,molding pressure,compression time and ultrasonic power supply had a great influence on the water resistance,the lowest value was about 44%.The moisture absorption rate quickly reduced with increase of compression time and ultrasonic power supply.While,compression time exceeded 90 s or ultrasonic power supply exceeded 80%,part of the biomass briquette fuel were carbonized and broken,resulting in an increase in the moisture absorption rate.The corn stalk particle size,molding pressure and moisture content of 8%-14%had little influence on moisture absorption rate.
