Why does furnace of high temperature kiln want heat preservation heat insolation?

Liner of furnace of high temperature kiln is to use fireproof material to build by laying bricks or stones is built and be become, the temperature inside furnace of the kiln when moving is very high, why to want heat preservation heat insolation? Say simply even if can be economical. What is adiabatic? Can the data that block sluggish thermal current transmits, say to heat up insulating material again. Heat-insulating material cent reflexes material for porous material and heat two kinds. Former the small opening that uses material itself place to contain is adiabatic, because the coefficient of thermal conductivity of the air inside space or inert gase is very low, wait like material of foam, fiber; A kind of material has very tall reflection coefficient after, can go out reflex of quantity of heat, the polyester that is like gold, silver-colored, nickel, aluminum foil or plating metal, get together acyl inferior amine film. What is heat preservation, how to come true? Maintain temperature to make heat does not come loose to go out or be passed, heat preservation is a kind of science, efficient heat preservation energy-saving technology, be about to insulation material park is fireproof of material palisade structure outside side, can achieve the goal of heat preservation heat insolation not only so, and the main body structure that still can protect a building, prolong the service life of the building. Why does furnace of high temperature kiln want heat preservation heat insolation? The main body function of furnace of high temperature kiln basically is decided by the technical economic performance of fireproof material, the investment cost that the implementation of heat preservation heat insolation can affect kiln furnace directly, character of service, thermal efficiency, the sources of energy that run uses up charge to wait, do heat insolation of good heat preservation, can managing the sources of energy, reduce fuel and heat energy prediction of a person's luck in a given year, remove cost saving thereby. Choose the general principle of fireproof insulation material: 1, the function of kiln furnace and hot project characteristic. The kiln furnace that works like clearance sex should choose the material with small thermal capacity. 2, intensity of system of the safe use temperature of material, heat conduction, high temperature, chemical stability. 3, use life. 4, investment expenses upholds charge with what move. Generally speaking, the fireproof material that pledges again emphasizes particularly on quite some specifications index, wait like high temperature stability, chemical stability; Be able to bear or endure to pledge insulation material pays attention to investment and the integrated technology economic norms that move more gently. When choosing light qualitative insulation material, it is the coefficient of thermal conductivity that uses insulation material commonly (λ ) the charge with insulation material of every unit volume (Ρ ) will decide, "λ Ρ " product value heals small had healed. Value of coefficient of thermal conductivity is little, the adiabatic result that shows insulation material is good, the fare of the sources of energy when moving is low. The fare of investment of charge low specification of insulation material of every unit volume is low, have good investment economy effect. Can use coordinate diagram method constructive alternative, the abscissa is working temperature, ordinate is (λ Ρ ) good indigestion, the intercept of safe use temperature that uses data the curve of each material, choose the stuff with technical good economic performance. Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
