First, the choice of high temperature flue gas parameters
The higher temperature heat source is beneficial to the drying process, while the flue and drying equipment has a limited ability to withstand the temperature of the flue gas. If the temperature of the extracted flue gas is too high, the boiler output will also have an adverse effect. Therefore, the high temperature smoke Gas parameters should be properly selected.
Second, the choice of drying equipment
Reasonable drying equipment (recommended to use RD sludge dryer), first of all to adapt to the layout space of the site, to achieve the purpose of transporting the blending after the sludge is dried, and at the same time take into account the operational performance requirements such as energy consumption and noise.
Third, the design of the transport blending process
As with the choice of drying equipment, the drying sludge conveying equipment should also be adapted to the limited space of the site and integrated with the existing coal handling equipment.
Fourth, the impact on the operation of the unit
In order to ensure the safe operation of the generator set, the interference of the start-stop of the drying system to the normal and stable combustion of the boiler should be as small as possible.
5. Prevention and control of secondary pollution
The design of the sludge drying system should fully consider and avoid the secondary pollution problem of the drying and conveying process to the environment of the power plant production area and the sludge drying workshop.
