Elimination of outdated furnaces of various furnace fuel consumption are quite different. According to statistics, a different type of kiln fired clay, high alumina clinker fuel consumption per unit of product are shown in Table 1, Tangshan saving kiln, kiln firing different products unit finished fuel consumption are shown in Table 2. Table 1 different type of kiln fired clay, high alumina clinker per unit of product coal fuel consumption table kg / t product Rotary kiln vertical shaft kiln soil clay clinker kiln clinker aluminous 140-160 65-80250-300 200 -280--400-500 Thus, energy-saving kiln, kiln calcination of raw materials, down draft kiln firing products, there are high energy consumption and serious environmental pollution, harsh operating environment issues. At present, these furnaces in the country is still lagging behind duplication, should resolutely stop. Kiln has been built behind the need for modification or elimination. After fifty years of industrial furnace refractories development, energy-saving kiln technology has been greatly improved. During the development of uniform provisions refractory furnace heat balance measurement and calculation methods, Hebei saving kiln, investigators monitored the situation refractory kiln pollution. This article focuses on the technical progress is mainly refractory industrial furnace; not enriched the development of ultra high temperature combustion technology; energy-saving light right kiln promotion; increase the level of automation kiln; the development of electric furnace kiln; promote the use of suitable refractory kiln environmental protection technology. Finally, to promote China's future industrial furnace refractories technological advances recommendations. 1 Introduction refractories industrial furnace for drying of raw materials, light burning material, sintering of raw materials, brick drying, baking products and heat-treated products do not burn, is to ensure the quality of key equipment refractory products, but also in production The energy-hungry. Due to a wide range of furnaces, kilns of this article focuses on vertical sintering of raw materials, products, rotary kiln and firing tunnel kiln, shuttle kiln of technological progress, and make recommendations for future work. 2 furnace refractories industry state of the art technology development with the expansion of raising the level of domestic and international technical and economic exchanges, refractories industrial furnace technology has made rapid development.
