1. Introduction
Mercury (Hg) is recognized as a pollutant of global concern due
to its long-range transport in the atmosphere and its persistence in
the environment. It bioaccumulates in ecosystems and has
numerous negative effects on human health and environment
[1]. Hg is a trace component of coal and secondary fuels. Hence,
electricity generation by coal fired power plants accounts for a high
share of total anthropogenic Hg emissions to the atmosphere [2].
However, significant efforts are being undertaken to control Hg
emissions of coal fired power plants. Numerous concepts of Hg
control measures were developed within the last decades and
are competing against each other in terms of removal- and
cost-efficiency. Several specific Hg control technologies are commercially
available, such as the addition of bromine compounds
to the fuel as well as dry sorbent injection to the flue gas [3].
However, those concepts are linked with additional capital and/or
operating costs of the required devices and consumables
