    • ways to calculate cfb boiler efficiency

      Ways to Calculate CFB Boiler Efficiency

      Combustion efficiency measures how effectively a CFB boilertransfers the chemical energy stored in fuel into usable heat. Reaching optimum combustion efficiency typically requires pumping additional air into the combustion chamber so that all fuel can be burned.
