Pingxiang Qunxing Manufacturers Supply Honeycomb Ceramic Thermal Storage Bodies

Description :

　　The comparative area of honeycomb ceramic thermal storage is more than 5 times that of thermal storage balls, with a heat transfer capacity 4-5 times greater, air flow resistance only 1/3 of that of balls, and a smaller heat transfer depth. So honeycomb ceramics are more conducive to achieving low oxygen combustion than heat storage balls, making the land temperature uniform, heat transfer speed, and rapid steel production, greatly reducing the generation of NOx and significantly improving environmental protection and energy efficiency. The use of honeycomb ceramic heat storage chambers greatly reduces the volume and allows for the installation of sufficient number of burners to meet the heat load requirements. The straight air flow channel of honeycomb ceramics is less prone to blockage compared to the maze channel of small balls, and has good self-cleaning properties, making it suitable for the characteristics of unclean combustion in China. Our company's newly developed mullite, cordierite synthetic and corundum honeycomb ceramic thermal storage body has significant characteristics such as high temperature resistance, corrosion resistance, good thermal stability, high strength, large heat storage capacity, and good thermal conductivity, greatly improving energy-saving effect and service life, and is highly favored by the steel industry.

　　The heat storage high-temperature air combustion technology (HTAC) has a dual effect of energy conservation and environmental protection. Compared with traditional combustion technology, it saves fuel by 20-50%, reduces oxidation loss by more than 20%, reduces NOx emissions by more than 40%, and greatly improves production efficiency. As one of its key components, honeycomb thermal storage has the advantages of large heat transfer area per unit volume, fast heat transfer, low airflow resistance, shallow heat transfer depth, and high thermal efficiency. There are various hole types such as square holes, circular holes, hexagonal holes, as well as various wall shapes such as flat, inclined, single groove, and double groove. Our technical personnel have boldly innovated based on the characteristics and usage environment of industrial furnaces in China, and have taken the lead in synthesizing honeycomb heat storage bodies, baffle bricks, and heat storage balls using high-temperature fused chromium corundum above 2000 ℃ and other high-purity materials in China. By utilizing the advantages of high fire resistance, high load softening temperature, good slag resistance, good thermal shock stability, fast thermal conductivity, good erosion resistance, large capacity, and large heat capacity of this synthetic material, its service life has reached the level of similar foreign products. In addition, the added catalyst undergoes catalytic combustion with CO and HC compounds in the flue gas at around 600 ℃, further improving waste heat recovery and reducing pollutant gas emissions. It is currently being widely promoted.

　　Regenerative high-temperature air combustion is a new combustion technology with both great energy saving and environmental protection. Honeycomb ceramic thermal storage is a key component of the regenerative burner, widely used in various heating furnaces, hot blast furnaces, heat treatment furnaces, cracking furnaces, baking furnaces, melting furnaces, homogenization furnaces, oil and gas boilers and other kilns in industries such as steel, machinery, building materials, petrochemicals, and non-ferrous metal smelting. This technology uses a reversing device to alternately absorb and release heat from two heat storage chambers, greatly limiting the heat of the gas, and then heating the combustion air and gas inside the furnace to over 1000 ° C. Even low-quality fuels with low calorific value can achieve stable ignition and combustion, saving fuel by 40-70%, increasing production by more than 15%, reducing steel oxidation and burning losses by more than 40%, NOx emissions by less than 100ppm, and exhaust gas temperatures below 150 ° C, greatly reducing the condition of the Earth's atmosphere and improving the human environment. There are three main types of thermal storage materials: honeycomb ceramics, thermal storage balls, and thermal storage tubes.
