Over half your energy costs are probably associated with your boiler, so improving boiler efficiency is a simple way to save money. You want some excess air as it's absolutely necessary for the boilers combustion process, but you want just the right amount - neither too much, nor too little. Try to find that ideal balance to achieve optimal combustion. Boiler efficiency is a combined result of efficiencies of different components of boilers . A boiler has many subsystems whose efficiency affects the overall boiler efficiency. Boiler Efficiency is in general indicated by either Thermal Efficiency or Fuel to Fluid Efficiency depending on the context. Combustion Efficiency – indicates a burners ability to burn fuel measured by unburned fuel and excess air in the exhaust Thermal Efficiency – indicates the heat exchangers effectiveness to transfer heat from the combustion process to the water or steam in the boilers, exclusive radiation, and convection losses ...
