05/05/2017 · There are four primary contributors to the serious fouling of the second stage: (1) there was acid condensate in the flue gas and on the tubes; (2) most of the ash particles in the flue gas were fine particles; (3) all the particles were charged in the electrostatic precipitator; (4) few big particles could scour the tubes and hit against the deposits.
01/06/2015 · Boiler slagging and fouling, and the resulting frequent operation of sootblowers, are some of the major operations and maintenance factors that can negatively affect power plant reliability and
What are the Boiler Flue Regulations? | Home Heating Guide
The heavy metals are in the gas phase at the high temperatures and escape with the flue gas. In the downstream boiler sections is the exhaust gas successively cooled. The fly ash settles on the heat transfer surfaces and causes fouling, possibly also blockages or adhesions in the flue gas path. In addition, the heavy metals condense more and more as the flue gas temperature drops, causing
