In big cities and economydeveloped cities, MSW incineration plants take more strict standard as EUDC2022, and dioxin concentration cannot over ngTEQ/Nm3 ? The Control for dioxin will be more and more strict. 35 6/8 我國垃圾焚燒技術(shù)應(yīng)用發(fā)展預(yù)測 Incineration Development Forecast CUCD 中國 ? The dry process developed rapidly in recent years, such as the lime granules are much smaller than before, and its processing effect have enhanced remarkably, and the application has increased a lot in foreign country as well. for example, the cities in Japan always choose this way except Tokyo which has a much higher environmental standard. 34 5/8 我國垃圾焚燒技術(shù)應(yīng)用發(fā)展預(yù)測 Incineration Development Forecast CUCD 中國 目前的干法處理效果有顯著提高，在國外的應(yīng)用有所增加。 城市建設(shè)研究院 China Urban Construction Design amp。 ? The most of the heat energy from incineration is changed into electric power since favorable power price can be get from Chinese government. ? In steam quality aspect ， the operation with inferior high temperature amp。目前，廣州李坑和中山焚燒廠采用三菱重工焚燒爐，嘗試使用次高溫高壓余熱鍋爐蒸汽參數(shù) 6MPa/450℃ 。 ? 在蒸汽參數(shù)方面，通常垃圾焚燒廠余熱鍋爐蒸汽參數(shù)為中溫中壓參數(shù)（ 4MPa和 400℃ ）。 城市建設(shè)研究院 China Urban Construction Design amp。 Research Institute Construction and Running of MSW Incineration Plants in China 爐排爐與流化床爐平分秋色，小型焚燒爐市場逐漸減小 Market Share Will Occupied by stoke grate Incinerator and Fluidized Bed Incinerator， Small Scale Incinerator will Quit Gradually ? 大中城市以機械爐排爐為主 ? 對于中小城市及內(nèi)陸城市和經(jīng)濟較發(fā)達(dá)地區(qū)，流化床的國產(chǎn)化技術(shù)、價格優(yōu)勢以及摻煤獲得的經(jīng)濟受益，仍將具有較大的吸引力。 ? The capacity of newly built plant are usually beyond 600 t/d, even up to 8001000 t/d in some big cities, and the capacity of one incinerator is usually 300600t/d. Affected by new energy policies, the incinerator develops towards the large scale tendency 31 2/8 我國垃圾焚燒技術(shù)應(yīng)用發(fā)展預(yù)測 Incineration Development Forecast CUCD 中國 城市建設(shè)研究院 China Urban Construction Design amp。 城市建設(shè)研究院 China Urban Construction Design amp。 ? According to the new Trial Guidelines on renewable Power Generation Price and expense ， the price of the power generated from the new waste incineration plant built after 2022 will up to： – Zhejiang: yuan/kwh； Guangdong: yuan/kwh。 ? 按照國家發(fā)改委頒布的 《 可再生能源發(fā)電價格及費用分?jǐn)偣芾頃盒修k法 》 規(guī)定， 2022年起新核準(zhǔn)建設(shè)的垃圾發(fā)電廠，上網(wǎng)電價應(yīng)分別為： – 浙江省 /度； 廣東省 /度。 城市建設(shè)研究院 China Urban Construction Design amp。 Research Institute Construction and Running of MSW Incineration Plants in China 28 ? 流動空氣的風(fēng)量差：左右空氣量比中央部分多 ? 傾斜式爐床：爐床由中央向爐兩端的不燃物排出口傾斜 ? 回旋流效果：從左右二側(cè)部分向上吹起的砂被導(dǎo)流板阻擋回流到爐的中延部分 日本荏原 CUCD 中國 循環(huán)流化床 Zhongke Tongyong Co. 目前已建和在建的焚燒項目有 10余項 ? 浙江嘉興熱電廠 ? 東莞市市區(qū)垃圾焚燒廠 ? 寧波市鎮(zhèn)海垃圾焚燒廠 ? 四川彭州垃圾焚燒廠 ? 城市建設(shè)研究院 China Urban Construction Design amp。 Research Institute Construction and Running of MSW Incineration Plants in China ? 高比重惰性物料循環(huán) ? 特殊布風(fēng)結(jié)合定向風(fēng)帽結(jié)構(gòu) ? 二次風(fēng)旋渦分段燃燒 ? 垃圾滲濾液回噴爐膛焚燒 26 浙江大學(xué) moreover, the loss of ignition is much lower, it only has 1~2%. ? The speed of flue gas is very high, and the attrition to equipment is serious. ? Compared with grate, it needs more repair, but has the shorter running time which is about 60008000hours per one year. ?
