Combustion controls regulate a fuel-fired system’s air and fuel inputs to maintain the air/fuel ratio within the limits that are required for proper combustion. These ratios are maintained throughout the operating range as specified by the burner manufacturer for the application, in accordance with demand. When comparing the various control systems available, though, how do you know which system will prove most beneficial for your operations? Do you know if your current system is up to date or accurately controlling the combustion process for your equipment? Learning more about combustion controls can help you sort through these questions as well as improve the operation of your fuel-fired systems.
