  • Effect of Black Liquor Firing Conditions on Salt Cake

    The recovery boilers were operated at 2-3 different loads and measurements were made during each load case. Dust samples from the flue gas and from the precipitator dust transport system were collected at all load cases. Several analyses were done of the dust samples to determine particle size, chemical composition and mechanical properties of Learn More

  • 4-4 Recovery Boiler Chemical Principles

    Most of the dust falls out of the flue gases into dust hoppers or is captured by electrostatic precipitators. From these the dust is fed back into the boiler by mixing the dust with the infeed black liquor. Roughly 10 % of the sodium contained in the black liquor is typically in this circulation. Correspondingly, the part of the sulphur carriedLearn More

  • Semi-Dry Flue Gas Desulfurization

    The CFB FGD system requires a filter for solids recirculation and dust removal. If it is possible to use the desulphurisation product in conjunction with the fly ash of the boiler, then there is no need to remove the dust upstream of the CFB FGD. If the boiler ash is marketed separately, the flue gas dust is removed in the existing filter.Learn More
