Alumina is hollow ball goods has distinct effect in energy-saving respect, it is especially in the application of kiln of furnace of high temperature industry. Its unique structure and superior performance make its make a kind of good energy-saving material. It is alumina below the energy-saving effect of hollow ball goods and its application advantage:
1.The interior of hollow ball is alumina of rate of low heat conduction hollow structure, this kind of structure reduced the integral density of material effectively, reduced the way that heat conducts, make alumina hollow the coefficient of thermal conductivity of ball goods is very low. Rate of low heat conduction is meant fall in high temperature environment, it can keep apart quantity of heat effectively, reduce the loss of quantity of heat of body of heater, reduce specific power consumption significantly thereby.
2. Alumina of high temperature stability is hollow ball goods is made by tall purity alumina, have exceedingly good high temperature resistant function. Although be in the high temperature environment of above of 1700 ° C, they also can maintain stable physics and chemistry. This makes its can reduce hot loss not only below high temperature environment, return the stability that can ensure equipment moves for long and dependability, reduced the stop production that causes because of equipment breakdown and maintenance cost.
3.The pledges character means them to be able to reduce body of heater gently whole of hollow ball goods weighs light qualitative characteristic alumina quantity. This conduces to managing construction cost not only, still can reduce thermal capacity, reduce heating up time, decrease to start and heat thereby the energy in the process is used up.
4.Superior heat preservation performance because its are low thermal conductivity and light simple character, hollow ball goods has alumina superior heat preservation performance. The liner that they can use at kiln of high temperature furnace or as heat-insulation layer, improve the heat preservation result of furnace kiln significantly, reduce be lost of the caloric inside furnace, improve thermal efficiency.
5.Economic energy resources is used up in applying actually, hollow ball goods can reduce alumina significantly the specific fuel consumption of furnace of kiln of high temperature industry. For example, in furnace of kiln of a few high temperature (be like kiln of vitreous kiln, pottery and porcelain) in, hollow ball goods regards use alumina as liner or insulation material, can reduce specific fuel consumption 10% to 30% , bring considerable energy-saving result.
6.Lengthen equipment life alumina hollow ball goods can reduce specific power consumption not only, still can pass its exceedingly good high temperature resistant and be able to bear or endure chemistry erodes performance, prolong the service life of high temperature equipment, decrease change frequency and maintenance cost, secondhand managing the sources of energy and resource.
7.Applied range is wide hollow ball goods applies to alumina equipment of all sorts of high temperature industry, the splitting decomposition furnace that is like industry of kiln of frit of kiln of agglomeration of muffle furnace, pottery and porcelain, glass, petrifaction. Its are energy-saving the effect got in these domains extensive test and verify is mixed approbate.
8.Environmental protection benefit is passed reduce specific fuel consumption, hollow ball goods returned alumina to reduce gas of room of carbon dioxide isotherm secondhand discharge, accord with the environmental protection demand that current industry expands, have favorable environmental beneficial result.
Hollow ball goods is in summary alumina the effect of energy-saving respect is distinct, behave in kiln of furnace of high temperature industry especially good. They are conducted through reducing heat, reduce loss of quantity of heat, reduce facility weight and improve heat preservation performance, can reduce specific power consumption significantly, lengthen service life of equipment, then managing cost reduces environmental pollution. Accordingly, alumina is hollow ball goods is applied extensively at needing domain of efficient and energy-saving high temperature industry.
