Biomass boilers take time to light, reach an efficient burn rate and to extinguish themselves. During all of this time they produce heat. Thus, they cannot modulate their heat output in response to changing heat loads in the same way as a modern modulating gas boiler (a modern hi/low oil boiler does modulate but not as well as gas).
Sep 01, 2020 · Consider the following ways boilers and their burners impact a companys bottom line. Fuel economy. On average, a boiler will consume in fuel four times its initial cost every year. Substantial savings can be achieved if the boiler, including the burner, has a regular maintenance schedule that is based on operating conditions.
