Comparison of Far-infrared Honeycomb Ceramic Burner and Metal Burner
A brief comparison between far-infrared honeycomb ceramic burners and metal burners.
Comparison of Far-infrared Honeycomb Ceramic Burner and Metal Burner
Far-infrared honeycomb ceramic burners differ significantly from metal burners in combustion methods, heat transfer efficiency, and applicable scenarios.
Core Differences
Comparison Items | Far-infrared honeycomb ceramic combustion plate | Metal burner |
Combustion Method | Catalytic flameless combustion | Flame diffusion combustion |
Heat Transfer Method | Primarily far-infrared radiation (50%-60%) | Primarily convection (30%-40%) |
Heating Rate | Fast (30-60 seconds) | Slow (preheating required) |
CO Emissions | ＜10ppm | 20-100ppm |
Operating Temperature | Plate surface 800-1000℃ | Flame 1200-1800℃ |
Failure Modes | Thermal shock cracking, catalyst poisoning | High-temperature oxidation, burn-through |
Service Life and Cost
Ceramic burners typically have a lifespan of 8,000-10,000 hours, with failure primarily due to thermal shock cracking; metal burners have a lifespan of 2-5 years, with failure mainly due to high-temperature oxidation.
Cost: Ceramic burners have a higher initial investment but higher thermal efficiency (50%-60%) and energy-saving operation, potentially resulting in lower long-term overall costs; metal burners have lower initial costs but lower thermal efficiency (30%-40%) and greater heat loss in flue gas.
Selection Recommendations
Far-infrared honeycomb ceramic burning plate is preferred | Metal burner is preferred |
Requires uniform heating and high surface quality | Heat large volumes of materials |
Requires low emissions (CO<10ppm) | Emission requirements are not strict |
Requires rapid heating | Continuous operation, and sufficient preheating |
Intermittent operation, frequent start and stop | Long-term continuous operation |
Heating sheet/coating/drying | Universal heating |
Summary
Ceramic burners have a higher initial investment but are more energy-efficient, while metal burners have a lower initial cost but higher heat loss. They are complementary and can coexist; the selection should be based on a comprehensive consideration of the heating object, surface quality requirements, and operating mode.
