Industrial Burners & Burner Assemblies
An industrial burner mixes fuel and air in the correct ratio and delivers a stable, controllable flame to a boiler, oven, furnace, or other process heating vessel. Burner design, whether a simple atmospheric burner or a fully packaged burner assembly, determines turndown range, emissions performance, and how tightly the flame can be modulated to match process demand.
Choosing the right burner means matching firing rate, fuel type, and turndown to the vessel it will heat, then pairing it with the correct burner control, gas train, and flame safety components elsewhere in this catalog. Properly matched burners improve combustion efficiency, reduce emissions, and lower the risk of unplanned downtime. These burners are suitable for new equipment builds, burner replacement projects, and capacity upgrades.
Shop Relevant carries industrial burners and package burners, including Eclipse burner assemblies built to arrive largely pre-piped and pre-wired for faster commissioning. The category spans burners sized for direct fired process heat, indirect fired boilers, and specialty combustion applications where a specific fuel type or turndown ratio is required. Same-day shipping available.
Frequently Asked Questions
What is a package burner?
A package burner is a burner assembly that arrives from the manufacturer largely pre-piped, pre-wired, and factory tested as a single unit, reducing field assembly time compared to building a burner from individual components on site.
How is a burner's turndown ratio determined?
Turndown ratio is the range between a burner's maximum and minimum stable firing rate, and it depends on burner design, fuel type, and how precisely the air and fuel valves can be modulated together across that range.
What determines the right burner size for my application?
Burner sizing starts with the heat input required by the vessel, expressed in BTUs per hour, then accounts for fuel type, combustion air availability, and the turndown range the process needs for stable operation at both high and low demand.
