Boiler Efficiency & Combustion
Boiler Combustion Efficiency
A boiler’s efficiency is how much of the fuel’s energy becomes useful steam, and the two levers that control it are combustion and heat recovery. Burn the fuel completely with just the right air, and capture the heat in the flue gas, and the boiler converts more of every tonne of fuel into the steam the plant needs.
What Drives Efficiency
- Complete combustion, achieved with the correct air-to-fuel ratio and good mixing.
- Excess air control, since too much air carries heat up the stack, and too little leaves fuel unburned.
- Heat recovery, reclaiming flue gas heat through economisers and air preheaters.
- Clean heat-transfer surfaces, since scale and soot insulate and waste fuel.
Why Small Gains Compound
Fuel is the boiler’s dominant lifetime cost, so a few points of efficiency recovered from combustion control or flue-gas heat are worth more than any one-time equipment saving. Because the boiler runs continuously, those points compound every hour into a large and permanent reduction in operating cost.
