Industrial/Commercial Boiler Burner Comparisons


Compare Boilers Compare Burners  Controls  Have Questions?

Many times a poorly performing burner can see significant gains by upgrading their controls. However, a burner’s life cycle is typically around 15-20 years. Sometimes it’s necessary to retrofit a boiler with a new burner, or replace boiler, burner and controls altogether. Autoflame and our Tech Centre Network have replaced tens of thousands of burners over the past 40 years, and have assembled this comparison chart of the industry leaders based on that experience.

Rating: Our objective overall review of this manufacture based on customer experience and satisfaction. Init Cost: Our overall experience in the initial cost of buying the burner and having it installed. Oper Cost: Our overall experience in ongoing operational costs, including fuel consumption (relative to similar sized burners), operation and servicing. Quotes: Typical number of business days to deliver a Quote. This is a good barometer for overall responsiveness from manufacturer. If they take 3 weeks to deliver a quote, imagine what it will be like getting support after the sale. Min 02: Minimum percent of O2 emissions with no CO throughout the firing range. The lower this number is, the cleaner the burner runs. Max Td: Maximum Turn Down ratio offered. A 1000kW (or 1MW) burner with a 10:1 turndown ratio has a minimum output of 100 kW. A high turn down ratio is desirable because it allows the burner to remain firing during off-peak times with very little fuel consumption. Warranty: Manufacturer’s warranty in months. “Ma” means the warranty begins from date the burner leaves the Manufacturer, while “co” indicates the warranty begins on date of Commissioning.
