Fly ash samples were collected from the coal-fired power plant in Shandong Province, China. The samples of fly ash, pure ash and different sizes of fly ash for were prepared for experiments. In the first stage, the collected fly ash was dried in drying oven at 105 °C for 2 h, cooled in a vacuum chamber, and weighted 150±0.5 g for each sample.
The project will be the 26th commercial-scale fly ash separator installed worldwide by STET. In 2020, SRMG announced the award of a fly ash contract with a Utah power plant. SRMG is currently constructing a new fly ash beneficiation facility at the plant utilizing the patented STET fly ash separation system.
Figure 1 shows fly ash produced in a typical pulverized-coal-fired utility boiler and collected by an electrostatic precipitator. There are two commonly used methods for removing the fine powdery fly ash from the fly ash hopper of the precipitator – a wet method or a dry method [12–15].In the wet method, water is used to flush the fly ash out of the hoppers …
