1. Control of initial water. The wet fly ash water that has just been discharged from the power plant is generally around 45%. At this time, drying immediately, the production cost is large, and the equipment also poses a great pressure. Stack in a well ventilated place for about 15 days, so that the water is reduced to about 20%, and then treated.
2. Selection of dust collector. Because the fly ash particles are fine and light in density, they are easily taken away by the airflow under the condition of negative pressure after drying, resulting in a change of the fluid medium, and the dusty gas has a large water content.
3, dry material conveying equipment should pay attention to sealing.
4, the choice of hot stove. The hot blast stove should be selected to have high efficiency, can fully burn low quality coal, and is easy to operate.

Polycarbonate roof sheets are a type of roofing material made from polycarbonate, a strong and durable thermoplastic material. These sheets are transparent or translucent, allowing natural light to enter a space while providing protection from the elements. Polycarbonate roof sheets are commonly used in applications such as greenhouses, skylights, patio covers, and industrial roofing. They are lightweight, easy to install, and offer high impact resistance, UV protection, and thermal insulation properties.
