    摘要:

    基于已有文獻(xiàn)實(shí)驗(yàn)數(shù)據(jù),，建立了木屑和煤,、稻殼和煤混合壓縮成型過程LS-SVM模型。結(jié)果表明,，兩種模型預(yù)測(cè)值與實(shí)驗(yàn)值相對(duì)誤差最大值分別為3.46%,、5.83%,，兩類型煤混合壓縮成型過程具有較好的模擬效果。在此基礎(chǔ)上設(shè)計(jì)擬合了兩類型煤混合壓縮成型過程多目標(biāo)優(yōu)化目標(biāo)函數(shù),，尋優(yōu)分別得到木屑,、稻殼與煤混合型煤壓縮成型過程Pareto最優(yōu)解集。依據(jù)生物質(zhì)固體成型燃料標(biāo)準(zhǔn)和生物質(zhì)型煤綜合性能CV值,，進(jìn)一步從Pareto最優(yōu)解集中選出了對(duì)木屑和煤,、稻殼和煤混合型煤不同指標(biāo)要求下的壓縮成型工藝過程運(yùn)行工況的優(yōu)化目標(biāo)值。

    Abstract:

    The compression process LS-SVM model of biomass compound coal mixed with sawdust, coal and rice hull was established according to the published experimental data. The test result showed that the maximum relative error of predicted and experimental values of two models was 3.46% and 5.83%, which proved the efficiency of model. On this base, the multi-objective optimization objective function of compression process was designed and fitted, by which the Pareto optimal solutions were gained in a single run. According to the standard target of solid biomass fuels and CV value which represented the comprehensive performance of biomass compound coal, the efficient solutions that are suitable for compression process were selected from the Pareto optimal solutions under different indicators for compound coal mixed with sawdust, coal and rice hull.
