根據(jù)冶金專業(yè)工程《沸騰焙燒爐設(shè)計(jì)》（朱云 編）下達(dá)的課程設(shè)計(jì)指導(dǎo)書任務(wù)。經(jīng)濟(jì)上合理，所以 ,設(shè)計(jì)應(yīng)遵循的原則和指導(dǎo)思想為： 遵守國(guó)家法律、法規(guī)，執(zhí)行行業(yè)設(shè)計(jì)有關(guān)標(biāo)準(zhǔn)、規(guī)范和規(guī)定，嚴(yán)格把關(guān)，精心設(shè)計(jì)； 要按照國(guó)家有關(guān)勞動(dòng)安全工業(yè)衛(wèi)生及消防的標(biāo)準(zhǔn)及行業(yè)設(shè)計(jì)規(guī)定進(jìn)行設(shè)計(jì)； 在學(xué)習(xí)、總結(jié)國(guó)內(nèi)外有關(guān)廠家的生產(chǎn)經(jīng)驗(yàn)的基礎(chǔ)上，設(shè)計(jì)中應(yīng)充分考慮節(jié)約能源、節(jié)約用地
