Basic Definition of Far-infrared Honeycomb Ceramic Combustion Plate
A brief overview of the basic definition of far-infrared honeycomb ceramic combustion plates.
Basic Definition of Far-infrared Honeycomb Ceramic Combustion Plate
The far-infrared honeycomb ceramic combustion plate is the core component of a gas-fired infrared radiation burner. It converts the chemical energy of the gas combustion gas into far-infrared radiation energy through catalytic flameless combustion, achieving highly efficient heating.
Basic Definition
The gas-air mixture enters the honeycomb channels, where flameless combustion occurs under the action of a catalytic coating on the inner wall of the channels. This heats the honeycomb ceramic plate to 800-1000℃, emitting far-infrared rays with wavelengths of 2-10μm for radiative heating. The radiative heat transfer efficiency can reach 50%-60%, higher than that of convection heating.
Structural Composition
Component | Description |
Honeycomb Channels | Parallel, straight-through pores, pore density 100-300 cpsi, square or hexagonal, wall thickness 0.3-0.6 mm |
Catalytic Coating | Inner walls of the channels coated with platinum, palladium, or rare earth oxides to promote flameless combustion and reduce NOx |
Frame Fixing | Stainless steel or ceramic frame for easy installation and warping prevention |
Common sizes: 300×300mm or 500×500mm, thickness 15-30mm.
Performance Characteristics
High radiation efficiency: 50%-60%, superior to convection heating.
Uniform heating: Temperature difference within ±10℃ on the plate surface.
Low emissions: CO < 10ppm, low NOx.
Rapid heating: Reaches operating temperature in 30-60 seconds.
Lifespan: 8000-10000 hours under normal use.
Differences from Ordinary Honeycomb Ceramics
Comparison | Far-infrared combustion plate | Ordinary honeycomb ceramic |
Function | Combustion + radiation | Heat storage/heat exchange |
Catalytic coating | Required | Generally not required |
Operating temperature | 800-1000℃ | Depending on operating conditions |
Summary
Far-infrared honeycomb ceramic combustion plates are integrated heating elements combining combustion and radiation. Their core structure consists of honeycomb channels (100-300 cpsi) + a catalytic coating + a fixed frame. Through flameless combustion, they achieve 50%-60% far-infrared radiation efficiency, providing uniform heating, rapid temperature rise, and low emissions. Selection should focus on pore density and the stability of the catalytic coating.
