I. Introduction Zhengzhou Constant Energy Technology Co., is a research, development, production, sales and service in one of technology-intensive enterprises. The company specializes in a variety of energy-saving industrial boilers, kilns, research and production of high temperature anti-corrosion coatings, heat insulation coating and high emissivity coatings and other energy-saving high-temperature coatings for improving high-temperature furnace oxidation resistance, anti-slagging and energy-saving insulation Performance has a unique technical advantages. The company has a strong development, testing, testing technology, closely tracking the development of science and technology, always pay attention to customer needs and expectations, we have introduced new products to meet market demand. Second, the market analysis of the use of low energy, the energy shortage problem is getting serious. In recent years, the state of the energy industry's support is growing. The number of industrial furnaces, a wide range of applications. But its energy consumption, serious pollution, saving energy are more and more attention. Low boiler furnace thermal efficiency, mainly due to the aspect of heat loss through the outer wall and the furnace lining erosion, on the other hand the inner wall of the lower furnace emissivity, severe slagging oxidation furnace tube, so that heat can not be effectively radiated to the furnace, heating efficiency low. High emissivity coatings as an important energy-saving energy-saving materials kiln the strong state support.
