秸秆固化成型燃料引火助燃剂研究

Development of ignition-assisting agents for the combustion of densified straw briquette fuel

以玉米秸秆块状成型燃料为试验原料，LLA-6型户用生物质炉具为试验装置，选取了废弃机油、废弃柴油2种废弃液体燃料为配制原料，按不同的体积比（5：1～1：5）相互混合，配制成9种液体引火助燃剂，以不同的用量对助燃剂进行了试验研究。结果发现，当用量≥5mL时除废弃机油和废弃柴油按5：1配比混合的助燃剂①JC51外的8种助燃剂均能顺利将成型燃料引燃，并且废弃机油和废弃柴油按1：5配比混合的助燃剂（9）JC15引燃效果最好。当用量为8～9mL时，40s即可使炉火达到炊事要求，比不加助燃剂的燃料引燃时间缩短了30～40倍。引火助燃剂的研究解决了秸秆固化成型燃料推广过程中普遍存在的点火难和使用不方便的问题。

Several ignition-assisting agents for the combustion of densified corn straw briquette fuel （DCBF） have been developed and studied. A type LLA-6 household cooking stove was used as the experimental device. Two waste liquid fuels （waste engine oil and waste diesel oil） were mixed in different volume ratios （5：1 - 1：5） to make nine ignition-assisting agents. Ignition tests were carried out in order to investigate the performance of nine ignition-assisting agents at different dosages. With the exception of （1）JCS1, all other eight ignition-assisting agents successfully ignited the DCBF. The ignition-assisting agent （9）JC15 was found to be the most effective, and could successfully ignite DCBF when the dosage used was more than 5 mL. The use of （9）JC15 with a dosage of 8 - 9 mL was optimal, taking only 40 s to ignite the DCBF, which was 30 - 40 times lower than that without the use of any ignition-assisting agent. This study has therefore solved the problems associated with the ignition of DCBF.
