Co-Firing Coal, Biomass and Waste Fuels in Circulating

The combustion of CO 2 neutral solid fuels like biomass and waste-based fuels with circulating fluidized bed (CFB) boiler designs has become an accepted way to generate electric power and process steam to reduce global CO 2 emissions (i.e. reduce "carbon footprint") and hence to reduce the potential impact on climate change. In the European Union, for example, there is a co-combustion

Fouling in coal-fired boilers: Biomass co-firing, full

As coal-fired boilers in The Netherlands are considered to be converted to high biomass co-firing or pure biomass boilers, issues with fouling by alkali salts are expected. The behaviour of gaseous alkalis is different in converted coal boilers than in dedicated biomass boilers due to the higher firing temperature.

Characteristics of Corrosion Related to Ash Deposition

In biomass and coal cofiring boilers, due to the high content of Si and Al in coal, most of the alkali metals exist in the form of aluminosilicate with lower reactivity and higher melting point, thus decreasing the content of chlorine and viscosity of the ash deposition, which means the corrosion related to ash deposition is slowed down .
