Tubular cracking furnace is one of the commonly used equipment in petrochemical, coal chemical and other industrial fields, and its operation needs to withstand high temperature, high pressure, corrosion and other harsh conditions, so special protective measures need to be taken to ensure the long life and stability of the equipment. Among them, energy saving and emission reduction, anti-coking, thermal insulation, and residual pot anti-corrosion are important problems that need to be solved in the operation of tubular cracking furnace.
In response to these problems, we have developed a new type of special coating with the following characteristics:
1.Energy-saving and emission-reduction coating: The coating has high reflectivity and high emissivity, which can effectively radiate heat out, reduce heat absorption and transfer, and thus reduce the energy consumption and emissions of equipment. At the same time, the infrared heating speed is fast, which can reduce the residence time of the material, thereby reducing the coking of the furnace tube.
2.Anti-coking coating: The coating has the properties of high temperature resistance and oxidation resistance, which can form a dense protective film under high temperature conditions to prevent coke deposition, thereby preventing the occurrence of coking phenomenon, and can also reduce the difficulty of coking and shorten the coking time.
3.Thermal insulation coatings: made of aluminum silicate fibers, heat-reflecting substances, rare earth powders and hollow ceramic beads, the coating has a low thermal conductivity. It has excellent thermal insulation performance and thermal insulation effect, which can effectively reduce heat loss and heat conduction, and improve the thermal efficiency and service life of the equipment.
4.Waste heat boiler anticorrosive coating: This coating can fully absorb the waste heat in the flue gas, and the thermal conductivity is as high as 25W mk, in the process of speeding up heat transfer, it can also protect the boiler tubes from the ** corrosion of flue gases.
In a word, the above-mentioned coatings have a wide range of application prospects and market prospects in the protection of tubular pyrolysis furnaces and other equipment. We believe that in the future, this coating will make a greater contribution to the sustainable development of the industrial field.
