The content of impurities is low, and it has a very low content of oxides such as iron and alkali metals. Therefore, the refractoriness is high, and the high aluminum content makes it maintain...
RTO, also known as regenerative oxidation device, uses ceramic regenerators to store the heat generated when organic waste gas is decomposed and uses the heat energy stored in ceramic regenerators to preheat and decompose untreated organic waste gas, so as to achieve high efficiency. With high thermal efficiency, the oxidation temperature is above 760°C, and the organic matter in the exhaust gas can be completely oxidized and decomposed in a short time. The regenerator is the core unit to reduce the operating cost of the RTO device. It can efficiently use the energy of organic matter in the process of oxidation and decomposition, and absorb and release energy. The treatment efficiency can reach more than 99.5%. No matter in terms of treatment efficiency or operation In terms of maintenance cost, it is a relatively good means to deal with organic waste gas at present. In RTO, the regenerator can repeatedly absorb and release heat. When the low-temperature organic waste gas passes through the regenerator, the regenerator releases the stored heat to the exhaust gas, so that the exhaust gas can reach the required preheating temperature. The temperature of the heating body itself is taken away; the preheated organic waste gas...
The main components of silicon mullite brick include aluminum silicate (Al2Si2O7) and silicon dioxide (SiO2). Silicon mullite bricks are refractory bricks made of special high-alumina bauxite clinker, andalusite, silicon carbide, and homogenized bauxite as the main raw materials, which are formed by high pressure molding and fired at high temperatures. The “silicon” in silicon mullite bricks refers to silicon carbide, and “Mo” refers to mullite. In fact, silicon mullite bricks are refractory bricks made of high alumina bauxite and silicon carbide as the main raw materials through sintering. Essentially, silicon mullite bricks are just high alumina bricks with silicon carbide added. Silicon mullite bricks are a refractory material usually made of a mixture of aluminum silicate and silica. These two components play an important role in bricks: Aluminum silicate (Al2Si2O7): also known as mullite (Mullite), is one of the main crystal phases of silica-molybdenum bricks. It has good fire resistance and thermal stability and can withstand thermal expansion and thermal shock under high-temperature conditions. Silicon dioxide (SiO2): also known as quartz, is another important ingredient in silicon mullite bricks. It has a high melting point and excellent high-temperature resistance, which helps to improve the refractory performance and thermal stability of...
