in the incinerator is completely solid waste,petroleum is just used as auxiliary fuel at the beginning;,Feeding waste does not need to pre-treat;,Mechanical move of grate make the waste agitate and mix completely,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 fly-ash is small,，,and the loss of ignition is very low as well;,The,technic,is very mature,，,and the equipment running time can be above to 8000 hours per one year.,The burning must be continual,turning on and

grate.,Adverse push can increase the staying time of MSW.,日本田熊,SN,型炉排炉,Takuma,Japan,设置两个阶梯，采用足够的炉排面积，使垃圾在炉内翻滚并燃烧；,采用四个驱动单位：一个在干燥阶段，二个在燃烧阶段，再一个在燃烬阶段。因此，通过调整各独立驱动单位的速度，能控制垃圾和灰层的厚度。,Two steps of ladders are established,and the area of the grate is big enough to let the waste roll well on it.Four actuating units:1 dry-step,2 burning,1 burned.So the thickness of the waste and residue can be controlled

needs quartz sand as the auxiliary material,and needs coal mixed with waste to achieve perfect combustion.The factory will economic efficiency more as more coal is mixed when the coal is cheap and electrovalence from MSW is more expensive than that from others in China.,all kinds of waste can be burned together,but it is 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 fly-ash amount is 34 times of that of grate;moreover,the loss of ignition is much lower,it only has 12%.,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 6000-8000hours per one year.,It is convenient to starting and blowing out.,25,流化床炉的技术特点,Fluidized Bed Incineration

Planned During 2006 to 2010,2,、新建垃圾焚烧厂将主要以大、中规模焚烧厂为主,New Incineration Plant Are Mainly Comprised by Large and Medium Scale Plant,我国新建的垃圾焚烧厂建设规模普遍大于,600,吨,/,日，我国大中城市新建的焚烧厂处理规模常在大于,1000,吨,/,日，焚烧厂配置以,2,3,台焚烧炉居多，单台焚烧炉的规模常在,300,600,吨,/,日，受政策影响焚烧炉的发展有大型化趋势。,The capacity of newly built plant are usually beyond 600,t/d,even up to 800-1000,t/d,in some big cities,and the capacity of one incinerator is usually 300-600t/d.Affected by new energy policies,the incinerator develops towards the large scale tendency,31,2/8,我国垃圾焚烧技术应用发展预测,Incineration Development Forecast,3,、炉排炉与流化床炉平分秋色，小型焚烧炉市场逐渐减小,Market Share Will Occupied by stoke grate Incinerator and Fluidized Bed Incinerator,，,Small Scale Incinerator will Quit Gradually,大中城市以机械炉排炉为主,对于中小城市及内陆城市和经济较发达地区，流化床的国产化技术、价格优势以及掺煤获得的经济受益，仍将具有较大的吸引力。,Stoke grate Incinerator will be the main choice in big cities.,Fluidized Bed incinerator will also be favored by some cities in the near future because of its advantages in investment and benefit from coal mixing.,32,3/8,我国垃圾焚烧技术应用发展预测Incineration Development Forecast,4,、近期内垃圾焚烧的余热利用将仍以发电为主,Power Generation is still the primary use in the near future,受我国可再生能源的影响，以及产品销路的稳定性、优惠的电价使得发电成为我国垃圾焚烧厂的热能利用方式相对单一，绝大多是焚烧余热都是用于发电。,在蒸汽参数方面，通常垃圾焚烧厂余热锅炉蒸汽参数为中温中压参数（,4MPa,和,400,）。若提高蒸汽参数将有助于提高余热利用效率，提高发电量，增加垃圾厂的收入，同时也加剧了余热锅炉材料的腐蚀，缩短了设备的使用寿命，增加了折旧成本。目前，广州李坑和中山焚烧厂采用三菱重工焚烧炉，尝试使用次高温高压余热锅炉蒸汽参数,6MPa/450,。采用次高温高压参数的经济性和对中国国情的适应性目前还在探索中。,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&pressure is still in exploration in China at present,and the incineration plants of,Likeng,in Guangzhou and of Center in,Zhongshan,are in the attempting with the condition 6MPa/450,they both choose the Mitsubishi-Marin grate.,33,4/8,我国垃圾焚烧技术应用发展预测,Incineration Development Forecast,5,、烟气处理工艺中干法的比例会有所增加Dry process will be widely used in flue gas treatment,随着技术的进步与发展，干法工艺也在提升和进步（如石灰粒度更细化、石灰喷射装置更优化等）。目前的干法处理效果有显著提高，在国外的应用有所增加。在日本，东京都焚烧厂对环境要求高，烟气处理均采用湿法处理工艺；东京都以外的焚烧厂烟气处理主要采用干法处理工艺。,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,我国垃圾焚烧技术应用发展预测,Incineration Development Forecast,6,、对二恶英的控制逐渐加强,Strengthening Dioxin control,大城市和经济发达地区的焚烧厂采用欧盟烟气排放标准，二恶英执行,0.1ng-TEQ/Nm,3,对二恶英的监控越来越严格,In big cities and economy-developed cities,MSW incineration plants take more strict standard as EU-DC-2000,and dioxin concentration cannot over 0.1 ng-TEQ/Nm3,The Control for dioxin will be more and more strict.,35,6/8,我国垃圾焚烧技术应用发展预测,Incineration Development Forecast,7,、垃圾焚烧厂建设融资模式多元化,Many Financial Models Will Emerge in MSW Incineration Projects,我国传统的垃圾处理设施是“政府投资建设，事业单位运营”。这种模式对于卫生填埋等技术水平相对较低的方式较为适用。对于焚烧项目，地方政府通常受技术水平和人才资源的限制，难以自建自管。,因此，部分城市采用了“政府投资建设，招标或委托企业运营”的方式，取得了较好的效果。,近年来，随着产业化政策的推广和国家投融资体制的改革，大量社会资本进入到垃圾焚烧处理邻域，“企业实行特许经营（,BOT,模式）”的方式广为应用。,Traditionally,the waste disposal facility is invested by the government,and operated by institution in China.Bt a incineration plant needs huge investment for construction and high-tech personnel to operate,so the construction and management is very difficult to be undertaken all by the government.,So,，,some cities used the method that government investing,entrusted company operating,and it already has obtained a very good effect in china.,In recent years,lots of social capital enters into the MSW incinerating domain,along with the national financing system reforming and the industrial production policy promotion.And the,BOT(Build,Operate-Transfer)mode is used especially widely.,36,7/8,我国垃圾焚烧技术应用发展预测,Incineration Development Forecast,8,、垃圾焚烧相关政策标准法规进一步完善,The policies related to MSW incineration will be gradually consummate,随着焚烧技术应用的发展，我国在相关的政策准法规建设也在逐步完善,国家已经颁布的标准有：,生活垃圾焚烧污染控制标准,(GB 18485-2001),生活垃圾焚烧处理工程技术规范,(CJJ90-2002),（已在修编）,城市生活垃圾焚烧处理工程项目建设标准,（已在修编）,城市生活焚烧厂评价标准,（在编）,The policies,laws,regulations and standards related to MSW incineration will gradually consummated along with the development of the technology.,The present national standards,：,Standard for Pollution Control on the MSW Incineration(GB 18485-2001),Technology Standard for MSW Incineration Project(CJJ90-2002),Construction standard for MSW Incineration Project(Compiling),Evaluation standard for MSW Incineration plant(Compiling),37,8/8,我国垃圾焚烧技术应用发展预测,Incineration Development Forecast,38,谢 谢 大 家,!,THE END,Thank you!,
