DEVELOPMENT PROCESS AND TREND OF WASTE TO ENERGY PROJECTS IN CHINA
-
摘要: 垃圾焚烧技术在我国得到了快速应用。2018年我国垃圾焚烧量达到1.02亿t,占总无害化量的45%,将很快形成"焚烧为主,填埋托底"的垃圾终端处理格局,也还将继续由"能量回收型"向"资源回收型"发展。垃圾焚烧工程不仅在规模上得到了增长,同时在焚烧技术、烟气净化系统和市场竞争形势上也发生了深刻变化。我国垃圾焚烧行业依然存在较多技术痛点和发展瓶颈,可持续发展面临新的挑战和机遇。未来,建议垃圾焚烧企业和行业应探索中小城市(<50万人口)垃圾焚烧推广和盈利模式,响应矿化垃圾开采及焚烧处置需求,补齐垃圾焚烧飞灰无害化处置和资源化利用短板;在"提高发电效率,降低厂用电率"等方面提高技术水平和管理能力,加强"邻利"理念引领;积极布局国际市场,重视与高校科研院所的互动,以推动技术创新和技术转移。Abstract: Waste to Energy (WtE) technology has been rapidly applied in China, with the incineration amount of municipal solid waste (MSW) reaching 102 million tons in 2018, accounting for 45% of the total harmless amount. The MSW disposal pattern of "mainly incinerated, lastly landfill" will soon be formed in China, and it will also continue to develop from "energy recovery" to "resource recovery". WtE industry has not only increased in the scale, but also has undergone profound changes in incineration technology, flue gas clean systems and market competition. China’s WtE industry still has many technical shortage and development bottlenecks, and faces new challenges and opportunities for sustainable development. WtE enterprises and all the participants involved WtE industries should explore the application and profit model of WtE in small and medium-sized cities (<500, 000 population), respond to the needs of landfill mining and incineration disposal, quickly develop the harmless disposal and resource utilization of fly ash; improve technology and management through increasing efficiency of power generation, reducing ratio of power consumption by the plant itself, strengthen the concept of "Good Neighborhood"; actively deploy the international market, attach the interaction with scientific research institutes in universities, and promote technological innovation and technology application.
