s better to mixed them up, and the separator and crusher is necessary before the incineration.? The waste in the fluidized bed is at aerosol fluidization condition, and the flyash amount is 3~4 times of that of grate。因此,通 過調(diào) 整各獨立 驅(qū)動單 位的速度,能控制垃圾和灰 層 的厚度。q Incline angle: 26176。q 燃燒空氣從爐底部送入并從爐排塊的縫隙中吹出,對爐排有良好的冷卻作用。? Mechanical move of grate make the waste agitate and mix pletely, and promote waste to burn up. Different makers of different incinerators have respective design characteristic.? Waste is burned stably and entirely, and the amount of flyash is small, and the loss of ignition is very low as well。? Fuel in the incinerator is pletely solid waste, petroleum is just used as auxiliary fuel at the beginning。 城市建設(shè)研究院城市建設(shè)研究院China Urban Construction Design Research InstituteConstruction and Running of MSW Incineration Plants in China 6全國城鎮(zhèn) “十一五 ”環(huán)境衛(wèi)生規(guī)劃Chinese Environmental Sanitation Plan (20232023)q 全國 “十一五 ”期間計劃新增的城市生活垃圾無害化處理能力為 24 萬噸 / 日 ,平均每年新增 萬噸 / 日;同時將采取封場、搬遷或改擴建等措施對現(xiàn)有約 70% 的不達標(biāo)設(shè)施進行改造,總規(guī)模約 萬噸 / 日;建設(shè)一批大型轉(zhuǎn)運設(shè)施并建立和完善收運系統(tǒng) ,城市生活垃圾無害化處理率不低于 60%; q 全國 “十一五 ”期間,全國城鎮(zhèn)環(huán)境衛(wèi)生固定資產(chǎn)總投資約為 1115 億元 。 城市建設(shè)研究院城市建設(shè)研究院China Urban Construction Design Research InstituteConstruction and Running of MSW Incineration Plants in China 城市生活垃圾產(chǎn)量預(yù)測 Municipal Solid Waste Output Forecast預(yù)計 到 2023年:? 全國 縣 城以上生活垃圾 總產(chǎn) 量 約為 噸– 城市: 噸 /年(日均 約為 )– 縣 城: 噸 /年(日均 約為 )To 2023 ?
