ABSTRACT
The
district heating company “Rigas siltums” operates biomass fuelled boiler in
Riga city. Three systems consisting of biomass boilers having a comparatively similar heat capacity and particle
abatement units like multicyclons, electrostatic precipitators and flue gas
condensers are compared. The main goal of the study is to evaluate the boiler
plant as a system where solid particles are both emitted and caught. The
results show that, the particulate matter can be efficiently trapped from flue gases by
the particle abatement technologies, and the electrostatic precipitator with
sufficiently large collection surfaces is able to provide appropriate flue gas
treatment of the particulate matter in the biomass boilers also without
pre-cleaning of the flue gas in multicyclons.
KEYWORDS
