Fuel/Air Control Systems
Automatic and continuous control of air flow distribution to match coal flow distribution is an industry-first application of this fuel injection type approach developed by Foster Wheeler.
Electric Charge Transfer (ECT) systems calculate the mass flow of coal in each conduit while Computer-Aided Design and Manufacturing (CADM) systems calculate the mass flow of air at each burner. This data is used together to establish the air bias needed to achieve balanced stoichiometric conditions at each burner. The bias at each burner is used by the plant's DCS system to automatically change damper settings for the correct air distribution to be obtained.
