The honeycomb ceramic regenerator

Regenerative high temperature air combustion (HTAC) double acting with energy saving and environmental protection, compared with the traditional combustion technology, fuel saving 20-50%, oxidation loss decreased by more than 20%, the reduction of NOx emissions by more than 40%, the production efficiency is greatly improved. As one of the key components of the honeycomb regenerator has unit volume heat exchange area, fast heat transfer, flow resistance is small, shallow depth, diathermy heat efficiency higher merit. A square hole, round hole, square hole, six pass and plane, inclined plane, single, double groove wall shape. Our technical staff according to the characteristics of industrial furnace in China and the use of the environment, bold innovation, the first in China to use high temperature above 2000 ℃ fused corundum and high purity materials synthesis manufacturing honeycomb regenerator, the baffle brick and regenerative ball. By using the synthetic materials, high refractoriness, refractoriness under load, high slag resistance, good thermal shock stability, fast heat conduction, scour resistance good, let the advantages of major, heat capacity, the service life reaches the level of similar foreign products. In addition, the catalyst added at 600 ℃ and CO in the flue gas, HC compound catalytic combustion, improving waste heat recovery and reduce pollution gas emissions, is now being popularized in large area.
