cfb boiler Agent erosion how to solve

Modeling of ash formation and deposition processes

The combustion of solid fuels will result in serious ash-related issues, such as corrosion, erosion, fouling and slagging, which will eventually lead to the efficiency reduction of the boiler and may in turn cause an unexpected shutdown [1,2].

Fly ash - Wikipedia

2019-7-17·Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify rapidly while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from 0.5 µm to 300 µm. The major consequence of the rapid cooling is
