high temperature kilns are key equipment for industrial heating. They are widely used in metallurgy, chemical industry, cement, power generation, glass, ceramics and other industries, but they have high energy consumption High pollution is a great challenge for the development of high-temperature kiln related industries. If China needs to take more complex parameters, the existing energy-saving technology is still very backward compared with developed countries, especially the heat energy utilization rate of high-temperature kilns needs to be greatly improved. Therefore, Zhisheng Weihua company has long studied the energy-saving technology of high-temperature furnace, and the use of new technologies, new processes and new materials to further improve the thermal efficiency in the furnace has become a hot spot in the study of ZS energy-saving coatings
the furnace is a three-dimensional space surrounded by the furnace wall for fuel combustion. The function of the furnace is to ensure that the fuel burns as much as possible and to cool the flue gas temperature at the outlet of the furnace to the temperature allowed for the safe operation of the convective heating surface. The high emissivity coating and high heat reflection coating are combined to make a composite coating, and the preparation of high-temperature thermal radiation technology is combined with high heat reflection technology and strong technical coating, which effectively improves the thermal efficiency of high-temperature kilns
painting zs-233 high temperature heat reflection coating and zs-1061 high temperature resistant far infrared radiation coating on the interior of high temperature furnace has higher energy-saving effect than painting a single far infrared coating. According to different insulation materials, the furnace interior is first painted with zs-1011 transition coating, and then painted with zs-233 high temperature heat reflection coating and zs-1061 high temperature far infrared radiation coating respectively
according to the thermal principle, the products are heated and sintered in the kiln, mainly relying on radiation heat transfer and convection heat transfer to complete the heat transfer of the heat source and the heated products. The lining coating of the kiln body covered with radiation coating can significantly improve the heat resistance effect of the kiln and maintain the furnace temperature for a long time. Beijing Zhisheng Zhisheng Weihua Chemical Co., Ltd. aims at the above problems. After thousands of tests and specific furnace use, it has been proved that zs-233 high-temperature heat reflective coating and zs-1061 high-temperature far-infrared radiation resistant coating spontaneously developed by Zhisheng Weihua researchers can effectively realize infrared isolation, weaken the conduction of high-temperature thermoelectric magnetic wave, reduce heat transmission, and have high high-temperature heat reflectivity, So as to effectively reduce the heat absorption of the object per unit time and reduce the surface temperature of the object. Zs-1061 high temperature resistant far infrared radiation coating has high temperature resistance, strong emissivity, corrosion resistance and high wear resistance. Through the infrared radiation of the coating, the heat exchange working condition in the furnace is improved, the combustion temperature and uniformity in the furnace are improved, the fuel combustion is more sufficient, the heating efficiency is achieved, the furnace temperature is improved, the energy is saved, the furnace inner wall is protected, and the service time of the furnace inner lining is extended
when the working temperature of the heating furnace is 700 ℃, the heat transfer is mainly radiation (more than 90%), and the energy-saving effect is better when two high-temperature energy-saving coatings of Zhisheng Weihua are used. The base material shall be painted with zs-233 high temperature heat reflective coating first, and then zs-1061 high temperature far infrared radiation coating. When the temperature of the high-temperature furnace is above 700 ℃, the zs-1061 high-temperature far-infrared radiation coating line absorbs heat and carries out high-infrared radiation. The zs-233 high-temperature heat reflection coating at the bottom is used as the heat shielding reflection coating of the zs-1061 high-temperature far-infrared radiation coating to avoid the excellent chemical corrosion resistance of zs-106, otherwise unexpected failures may occur. 1. The high-temperature heat absorbed by the high-temperature far-infrared radiation coating is transferred to the thermal insulation materials on the inner wall of the furnace, Reduce heat loss and increase infrared radiation. The special treatment of zs-233 high temperature heat reflective coating material has high reflection, shielding and emissivity of infrared electromagnetic waves at different temperatures, which effectively reduces the heat absorption rate of the material in unit time, reduces the heat transmission amount in unit time, increases the reflectivity, shielding rate and emissivity of infrared rays, and increases the thermal resistance value of the material
Beijing Zhisheng Weihua zs-1061 high temperature resistant far infrared radiation coating ZS is a special functional energy-saving coating with high temperature resistance (temperature can reach 1800 ℃), strong emissivity (0.95), corrosion resistance and high wear resistance. Through the infrared radiation of the coating, it can improve the heat exchange in the furnace, improve the temperature field strength and uniformity in the furnace, make the fuel burn more fully, increase the thermal efficiency, greatly improve the thermal efficiency of refractories, and reduce energy consumption Save energy and prolong the service life of furnace lining. Zs-1061 high temperature resistant far-infrared radiation coating contains strong radiation materials that radiate extremely penetrating far-infrared waves at high temperatures, making the molecular absorption wave of the heated object produce energy level transition, absorbing energy evenly heated, reducing heating time, and fully saving energy. The composite coating of high temperature heat reflection coating and near-infrared radiation coating saves energy more obviously
