At 16:06 on December 16, 2020, the generator set of Dunhua Municipal solid waste incineration project of Welli Group was successfully connected to the grid for power generation. The sound, vibration and bearing temperature of the turbine generator set meet the requirements of technical specifications, and the system runs normally when the unit is connected to the grid and starts to run with load. The success of the grid-connected power generation project indicates that Welly Group has the industry-wide operation capability in solid waste fields such as landfill, incineration, kitchen waste disposal, hazardous waste incineration, and construction waste. 

The construction site of Dunhua Municipal solid waste incineration project is located in the original landfill site of Dunhua City, which mainly deals with Dunhua urban solid waste. According to the survey, Dunhua urban household waste mainly includes household waste, food service kitchen waste, sanitation cleaning waste and a small amount of green waste. Because the city is in the construction period, there is also a small amount of construction waste mixed in the garbage. At the same time, in order to maintain the city's appearance and health, the Dunhua municipal government has increased the collection of garbage in the surrounding towns, so the composition of agricultural and forestry waste has increased. 

      As the first domestic household waste incineration power generation project under Willey Group, Dunhua project carries out General Secretary Xi Jinping's new energy security strategy of “four revolutions and one cooperation”, and aims to build a power plant with “characteristics of the times and characteristics of the Group”. It adopts mature, reliable and advanced harmless treatment technology for household waste incineration power generation, and ultimately achieves the purposes of harmlessness, minimization and resource utilization.

The scale of the project is one furnace and one machine, the daily waste treatment is 500t, the annual waste treatment is 166,500 t, equipped with 1*500t/d grate incinerator, 1*9MW condense-type air-cooled turbine generator set, and the annual operation is 8000h. 

In the process of project construction, we fully implemented the infrastructure control system of Welly Group, adhered to safety as the first priority, strictly organized, overcame difficulties, and solidly promoted the project construction. In order to ensure the success of the unit's grid-connected power generation, the project department of Welly Group mobilizes strong soldiers, increases the technical backbone force, and works on site shifts to carefully monitor and escort the unit's smooth grid-connected power generation, and responds quickly and actively to do a good job of the on-site defect elimination and related electrical tests in an orderly manner, cooperating with the owner, supervision, commissioning and centralized control operation personnel. In strict accordance with the requirements of the whole set of unit start-up scheme, the preparatory work of the unit before grid connection has been successfully completed. The unit has entered the whole start-up trial operation stage since the beginning, the boiler ignition and the unit impulse speed have achieved a success, the system equipment runs smoothly, and the main operating parameters are all qualified. 

At present, the project department of Welly Group and the project participants in close cooperation, sincere cooperation, to 72+24 hours of trial operation goal sprint. 

The construction of this project will enable Dunhua City to have a stronger power supply capacity, provide a strong power support for the vigorous development of the local economy, and help achieve the goal of energy conservation and emission reduction. At the same time, it has played a huge role in promoting the transformation of waste into treasure, improving the urban environment, optimizing the energy structure and protecting the regional environmental quality.
