蓄熱球介紹
蓄熱球是通過高溫燒結而成，它材質的主要成分是氧化鋁。具有強度大，耐高溫、耐高壓、耐強酸堿腐蝕，抗震穩定性好的特點，以工業氧化鋁和耐火高嶺土為主要原料，經科學配方、成形和高溫煅燒製成的，耐火瓷球最高耐熱溫度可達到1900度。按照滾製和機壓成型法兩種。密度高、熱阻小、強度高、導熱性能好、抗氧化、抗渣性強、導熱率和熱容量大、蓄熱效率高；熱穩定性好、溫度劇變時不易破裂等優點.比表麵積可達到240m2/m3。
在使用時蓄熱球將氣流分割成很小流股，氣流在蓄熱體中流過時，形成強烈的紊流，有效的沖破瞭蓄熱體表麵的附麵層，又由於球徑很小，傳導半徑小、熱阻小、密度高、導熱性好，故可實現蓄熱式燒嘴頻繁且快速換向的要求。主要用於化工行業的高溫、高壓、腐蝕性強的工作環境，是廣大石油、化工行業中轉化爐、反應爐、填料塔中最為理想的填料。
Regenerative ball is through high heat sintering, its material mainly of alumina. Has the strength, resistance to high temperature, high pressure resistance, strong acid and alkali corrosion, seismic stability of good characteristics, industrial alumina and refractory kaolin as the main raw material, through scientific formula, forming and high temperature firing, made of refractory porcelain ball maximum heat resistant temperature can reach 1900 degrees. According to the roll system and machine pressure molding in two. High density, small heat resistance, high strength, good thermal performance, strong oxidation resistance, slag resistance, thermal conductivity and thermal capacity big, high thermal efficiency; Thermal stability, temperature change is not easy to fracture, etc. Specific surface area of 240 m2 / m3.
When use regenerative ball will flow into small flow, air flow in regenerator have been out of date, the formation of strong turbulence, effective broke through the accumulation of heat on the surface of the body surface boundary layer, and as the ball diameter is very small, small transmission radius, small heat resistance, high density, good thermal conductivity, which can realize regenerative burner frequent and rapid directional control requirements. Mainly used in chemical industry of high temperature and high pressure, strong corrosive environment, is in the petroleum, chemical industry conversion furnace, reactor, the ideal packing tower packing.
