Boilers are pressure vessels designed to heat water or produce steam, which can then be used to provide space heating and/or service water heating to a building. In most commercial building heating applications, the heating source in the boiler is a natural gas fired burner. Oil fired burners and electric resistance heaters can be used as well.

and boilers can typically operate at recirculation rates of 20-25 percent without adversely affecting boiler heat transfer and efficiency. This comparison illustrates that the increased flow of LFG as compared to natural gas will not adversely affect boiler operation, although the burner, controls, and fuel train will require some modifications.
