Maintain a Proper Air-Fuel Ratio in Boilers
Constant regulation of the air-fuel ratio in boilers is an excellent pollution prevention measure. The optimal ratio of air-fuel mixture ensures complete combustion of the fuel, resulting in reduced emissions of harmful gases such as CO, SOx, NOx, and others associated with incomplete combustion. This leads to higher heat output and increased boiler efficiency.
Achieving complete combustion of fuel maximizes heat output and enhances boiler efficiency. To maintain this ratio, various control systems available in the market can be utilized. Additionally, proper maintenance and cleaning of fuel lines and burners are crucial. This includes reducing air infiltration, maintaining the gas-side heat transfer surface, ensuring proper start-up and shutdown, and providing adequate training to boiler operators. Training on the air-fuel ratio, its significance, setting procedures, and the consequences of incorrect settings can significantly reduce pollution and enhance efficiency.
Low-emission fuels like natural gas can mitigate the issue of incomplete combustion and high emissions during boiler warm-up. Natural gas is a low-nitrogen fuel that produces minimal NOx when burned as a fuel.
Therefore, regulating air-fuel mixtures in boilers involves the application of modern control systems, proper maintenance and cleaning, staff training, and the utilization of clean fuels. These measures contribute to minimizing pollution emissions and enhancing boiler efficiency, making industrial practices more environmentally friendly.
