Abstract
An atomizer system 160 for use in a spray dry absorber 130, the atomizer system 160 includes a support member 161, an atomizing disc 162 rotatably coupled to the support member 161, a first feed line 163 for delivery of a reagent slurry 163a to a delivery area 165 and a second feed line 164 for delivery of a dilution liquid 164a to the delivery area 165. The delivery area 165 is positioned within the atomizer system 160 to reduce scale buildup generated by interaction of the reagent slurry 163a and the dilution liquid 164a.
Claims12
A method for reducing scale buildup in an atomizer system, the method comprising the steps of:
- providing an atomizer system to a flue gas processing system, the atomizer system having a support member, a first feed line, a second feed line, an atomizing disc, and a delivery area, separate from the atomizing disc, arranged vertically above and upstream of the atomizing disc;
- delivering a reagent slurry to the atomizer system, the reagent slurry delivered through the first feed line to the delivery area;
- delivering a dilution liquid to the atomizer system, the dilution liquid delivered through the second feed line to the delivery area;
- and
- delivering dilution liquid and reagent slurry from the delivery area to the atomizing disc for atomization by the atomizing disc.
