An ethylene cracking furnace is a device used to produce ethylene. Ethylene is an important chemical raw material, which is usually produced by thermal cracking process. The decomposition of heavy-duty hydrocarbon feedstock, usually petroleum feedstock or natural gas, into ethylene and other by-products. The following is the structure of the ethylene cracking furnace and an introduction to the refractories used in each part of the furnace. Structure of Ethylene Revamp Furnace Heating furnace. The core part of the ethylene cracking furnace is the heating furnace. It is used to provide high temperature and heat energy to promote the decomposition of hydrocarbons. The reactor. The part behind the heating furnace includes the reaction catalyst, such as graphite, metal catalyst, etc. It is used to catalyze the decomposition of hydrocarbons. Separation device.

Tar dolomite refractory brick products are various shaped refractory brick products made from high-quality sintered dolomite as raw material and adding tar or asphalt as binding agent. Tar Dolomite Refractory Bricks (1) Characteristics of raw materials. Sintered dolomite is the main raw material for tar dolomite refractory brick products, and its chemical composition, sintering degree and freshness must be qualified. Tar and asphalt act as binding agents in tar dolomite refractory brick products. It is distributed between the sintered dolomite particles and partially penetrates into the interior of the dolomite. During the heating process, fine volatiles are softened, leaving fixed carbon, which is further graphitized to form a carbon network skeleton. Thereby enhancing and improving the high-temperature structural strength (load softening temperature), slag resistance and hydration resistance of the product. At the same time, the carbon mesh skeleton improves the thermal conductivity

For hazardous waste treatment rotary kilns, the composition of hazardous waste is complex and diverse. Among them, medical hazardous waste includes glass slides, infusion bottles, injection tubes, surgical residues, animal testing waste, etc. Therefore, the complexity of the chemical composition of hazardous waste is determined. Hazardous waste is generally burned in a rotary kiln at a temperature of 700 to 1000°C. Moreover, the main component of the gas after calcining hazardous waste is acidic. mullite castable for hazardous waste rotary kiln Working Conditions for Refractory Castable Lining of Hazardous Waste Rotary Kiln Among refractory materials, refractory bricks, and castables have good stability against acidic gases such as sulfuric acid gas and hydrogen chloride gas. However, when the operation is stopped and the temperature in the rotary kiln drops below the dew point, the corrosion caused by the acid needs to be considered. Among them, when the chlorine concentration exceeds

Corundum-mullite refractory castable has the advantages of high softening temperature under load, good chemical stability, and thermal shock resistance. Silicon carbide is widely used as a high-grade refractory raw material for the lining material of industrial kilns such as blast furnaces and heating furnaces. Among refractory materials, alkali resistance, corrosion resistance, high thermal conductivity, thermal shock resistance, and crusting resistance have always been the focus. High-alumina mullite bricks containing an appropriate amount of silicon carbide have been widely used in the decomposition zone and transition zone of cement rotary kilns, and their service life is 3 to 4 times longer than that of high-alumina bricks. Foreign studies also believe that adding silicon carbide can reduce the formation of low-melting point feldspar mineral phases and make castables have certain self-healing properties.
