Embodiment Construction

[0006] 1. The present invention adopts the combustion plate of porous honeycomb cordierite (ceramic plate) coated with a special catalyst as the core element.

[0007] 2. Use the ejector to inhale a considerable amount of air (primary air coefficient α = 1.05 or more) to mix combustible gas (natural gas, liquefied petroleum gas) and combustion-supporting gas (air) in a scientific proportion. The gas-air mixture is burned in each fire channel of the ceramic plate (no secondary air is needed), so that the radiant surface temperature of the ceramic plate reaches above 800-900°C.

Abstract

This invention relates to a gas-premixing infrared combustor that adopts special ceramic plate as the core component and mixes combustible gas (natural gas, liquefied petroleum gas) and combustion-supporting gas (air) in a rational ratio. The mixture of gas and air burns inside the flues of the ceramic plate (without secondary air), which increases the radiant surface temperature to 800-900deg.C and enhances the energy conversion ability significantly to saves energy furthermore.

Description

Technical field [0001] The invention relates to a gas premixed infrared burner, which belongs to the technical field of energy-saving burners. Background technique [0002] At present, the performance of most of the gas stoves with infrared radiators produced is not up to standard, and the carbon monoxide content in the flue gas exceeds the standard. After a series of experiments, we put forward our point of view based on the experimental data and relevant foreign materials. [0003] In addition to proper primary air, the atmospheric burner also needs sufficient secondary air to ensure complete combustion. For this reason, a lot of heat is dissipated in the secondary air heating. This heat loss is difficult to reduce, and the thermal efficiency is not easy to improve. [0004] The well-known radiation heat transfer is proportional to the fourth power difference of the absolute temperature between the heat transfer objects. When the radiation surface is relatively close to...
