Why does the furnace wall of kiln furnace want heat preservation?

Kiln furnace heat preservation is for green energy-saving environmental protection, reduce caloric waste, at the same time also the fee that reductive place uses fuel, it may be said is kill two birds with one stone.



The heat preservation of kiln furnace is energy-saving method 1. The heat preservation rate of kiln wants taller, implementation of ability of specific power consumption is smaller. The proposal besmears in kiln wall a coating, the material of coating is high temperature resistant, heat preservation, adiabatic. The heat preservation that can maintain 92% above so is led, reduce loss of the quantity of heat outside furnace, fall through high fever low consumption. 2. Often burn the high temperature furnace of fireproof material. Because work for a long time, fireproof material can be corroded inside kiln. As a result of the influence of oxidation, the proposal besmears on fireproof material Fu is high temperature resistant coating, in order to improve fireproof data save and service life.
With what material is heat preservation of industrial kiln furnace better? One, module of fiber of pottery and porcelain passes heat energy force to differ. When module of fiber of pottery and porcelain interweaves, what did not make clear is directional. When quantity of heat is delivered, deliver along fiber normally. This kind directional make quantity of heat cannot be delivered quickly. In addition, when fiber and hot surface are contacted, hang down to be touched directly rarely, this makes quantity of heat delivers fiber to go up hard. 2, the gas in module of fiber of pottery and porcelain is overmuch, the fiber with convection bad heat exchange interweaves together, can form a lot of air chamber, dormant air was filled inside. We know air passes heat energy force to differ, it is dormant air what is more,the rather that more. These static gas conduct heat on one hand the effect is poor, on the other hand also can block up steam flows inbreak. 3, thermal resistance of module of fiber of pottery and porcelain is great, fibrous contact dot can be achieved 80% , expanded to conduct heat further thermal resistance. Fiber-optic itself is opaque, so hot ray cannot be in fiber-optic in transmission, fiber-optic area is small, reception radiation is little, so heat radiation basically cannot be in fiber-optic on transmission.
The choice of insulation material should change function and economic benefits according to use condition, manage (1) equipment runs temperature. It is kiln furnace or equipment the regular job temperature in use process. A little fireproof after all data is used below so high temperature, want to consider its wear. (Insulation material uses 2) temperature is higher. The use temperature prep above that picks fireproof material this temperature, can destroy the function of fireproof material and service life. (3) heat proof quality, include density of coefficient of thermal conductivity, bulk, specific heat, thermal capacitance to wait. The ability that conduct heat. (4) use condition. Manufacturer of a lot of industry makes efficiency to carry a senior engineer now, unified exam Lv works in the air such as CO\H2, so the choice pledges adiabatic and fireproof material wants to consider to fight the side such as oxidisability, reproducibility gently. (5) physics function, if mechanical intensity is mixed,heat expands characteristic. Compressive strength of normal temperature high temperature is not high, allow changeful form or cave in. If coefficient of expansion is exorbitant, the bulk below high temperature expands to destroy integral function very easily. (6) chemistry, if be able to bear or endure soda acid sex. Basically consider pair of acidity or basic slag or solution be able to bear or endure suffer a gender. (7) economic benefits, include difficulty of the price, construction, wear. This does not explain more, concern with money. Company capital is abundant, use high quality insulation material.
Furnace of high temperature kiln commonly used light qualitative heat-insulating material includes insulation material sort to pledge corundum turns brick of light qualitative clay, light qualitative tall aluminous brick, gently, Molaishi gets together light brick, diatomite brick finalize the design fireproof material, adventitious fireproof material basically has light qualitative clay pouring makings, light qualitative tall aluminium is pouring makings of makings, tall aluminous daub, fiber kind include cotton of fireproof fiber blanket, fireproof fiber to wait, its price each are not identical.
Why does the furnace wall of kiln furnace want heat preservation? According to above content everybody can be clear about heat preservation roughly the action to furnace of high temperature kiln -- environmental protection is energy-saving, reduce cost.
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.
