On the morning of December 20th, the Guilin City’s Shankou Domestic Waste Incineration Power Generation Project was officially ignited after three years of construction. The project will not only undertake the task of harmless treatment of domestic garbage in the city, but also produce green energy for daily life use of the citizens, which marks the realization of treatment of domestic garbage in the manner of “garbage great reduction, utilization and harmlessness” in the city.
Shankou Project is located in Shankou Village, Lingui Town, Lingui District. It covers an area of about 147 mu and is invested and operated by Shenzhen Energy Environmental Protection Co., Ltd., with a chartered period of 30 years. The first phase of the project will design and build 2 sets of mechanical grate furnaces with a daily processing capacity of 750 tons. The furnaces are working with the medium-temperature medium-pressure waste heat boiler system, one 35MW (MW) steam turbine generator set, flue/gas purification system, slag collection and storage system, and fly ash collection and stabilization system, sewage treatment system, circulating cooling system, and other equipment. It uses the process of “waste full-burning + fly ash stabilization + residual landfill”, and uses the waste heat from waste incineration to generate electricity. The project has been implemented since December 2015. After more than three years of hard work, it has built a modern domestic waste incineration and power generation plant that is superior to the national standard and even the EU environmental protection technology standards.
According to the relevant person in charge of the project, after the project is put into production, it can annually treat 547,500 tons of domestic garbage, generate 210 million kWh which can be used by the project itself, or sold 180 million kWh to the grid. Equivalently, it can annually save 66,000 tons of standard coal and reduce carbon dioxide emissions by 220,000 tons. At the same time, it can also reduce waster weight by about 80%, or in other words, reduce waste volume by more than 90%, effectively alleviating the problem of garbage disposal in the built-up area of the city and saving land resources. With the first phase of the project being put into operation, the second phase of the project is about to start that will expand the scope to achieve solid waste incineration full coverage, and fundamentally solve the problem of urban and rural domestic garbage pollution.
