Utilization of slag in Incineration power plant

Utilization of slag in Incineration power plant

The slag of Incineration power plant refers to the solid waste generated in the process of Incineration, which is usually a gray powdery substance. These slag are usually considered as waste, but in reality they can be utilized as a useful resource. In this paper, we will discuss the utilization of slag in Incineration power plants.

1. Source and composition of slag

Incineration power plant is a way to treat garbage. It burns garbage into heat energy and uses heat energy to generate electricity. In this process, slag is an inevitable product. The composition of slag mainly includes: unburned garbage, burned ash, metal, etc.

2. Treatment method of slag

There are usually two ways to treat slag: landfill and utilization. Landfill is the direct dumping of slag into a landfill, which not only wastes resources but also causes environmental pollution. Utilization refers to the reuse of slag as a useful resource. Below, we will introduce several ways to utilize slag.

3. Utilization of slag

3.1 Cement production

Slag can be used as a mineral admixture in cement production, replacing some cement raw materials, reducing production costs, and also improving the strength and durability of cement.

3.2 Brick and tile production

Slag can be used as a mineral admixture in brick and tile production, replacing some clay raw materials, reducing production costs, and improving the strength and durability of bricks and tiles.

3.3 Road construction

slag can be used as roadbed filler and pavement material in road construction, replacing some stones and sand, reducing construction costs, and also improving the strength and durability of the road.

3.4 Sewage treatment

Slag can be used as a mineral admixture in sewage treatment, replacing some of the sludge, reducing treatment costs, and also improving the efficiency of sewage treatment.

4. Advantages of slag utilization

The utilization of slag can not only reduce the load on landfills and environmental pollution, but also reduce production costs and improve resource utilization efficiency. At the same time, the utilization of slag can also promote the development of circular economy and achieve sustainable development.

5. Conclusion

Although the slag of Incineration power plant is a kind of waste, it can actually be used as a useful resource. Through various methods such as cement production, brick and tile production, road construction, and sewage treatment, the reuse of slag can be achieved, production costs can be reduced, resource utilization efficiency can be improved, circular economy development can be promoted, and sustainable development can be achieved.
