energy being transferred to the boiler’s internal components. Burners Burners inject air and fuel through a distribution system that mixes them in proper concen - trations so combustion can occur. Most boilers use natural gas, fuel oil, or coal burners to provide heat to the boiler. The key components of natural gas burners
fuel and larger, more capital-intensive facilities are necessary to generate a unit of power with lignite than is the case with bituminous coal. The disadvantages arise because: (1) lignite's lower heating value means more fuel must be handled to produce a given amount of power; (2) the energy and maintenance
