What role does the fuel type play in boiler operation?

The fuel type significantly influences both the environmental impact and the efficiency of boiler operation. Different fuels produce varying levels of emissions when burned. For instance, natural gas generally burns cleaner than coal, which can lead to higher greenhouse gas emissions. The choice of fuel also affects the overall efficiency of the boiler, as some fuels provide more energy per unit of weight or volume than others, which can impact how much fuel is needed to produce the same amount of steam or heat. Therefore, the selection of fuel not only determines operational costs but also plays a crucial role in conforming to regulatory standards and addressing environmental concerns, making it a pivotal factor in the design and operation of boilers.
