What is the definition of fly ash rate?

Refers to the proportion of combustible substances and other incomplete oxidation products in solid fuel discharged from combustion equipment in the form of dust after combustion or incineration.

Fly ash ratio is usually expressed by mass ratio or volume ratio. Its level can reflect the combustion efficiency and environmental pollution. High fly ash rate may mean that there is incomplete combustion in the combustion process, which leads to energy waste and increased pollutant release. Low fly ash rate means that the combustion process is more complete and efficient.

The determination of fly ash rate is usually calculated by collecting particulate matter in flue gas discharged from combustion equipment, and after proper treatment and analysis. These data are of great significance for evaluating the performance of combustion devices, improving the combustion process and reducing environmental pollution.
