The steam supply options comprise conventional pulverized-coal and stoker-fired boilers, atmospheric fluidized bed boilers, and low- and medium-Btu gas fueled units. Oil-fired boilers were included for comparison purposes.
Biomass cofiring with coal represents an attractive option for reducing greenhouse gas emissions from coal-fired boilers. In general, there are compelling reasons to pursue this option as reviewed in the introduction. However, there are many issues that, if not carefully managed, could compromise the boiler or downstream processes.
This has led to a reduction in coal-fired electricity generation, with some of the coal-fired generation being replaced by natural gas-fired generation. The selection of the most advantageous option is influenced by factors such as performance, capital cost, operating cost, fuel flexibility and emissions control requirements.
