Does rubbish incinerator choose fireproof material to need what to requirement satisfy?

Rubbish incinerator is fireproof material lining must be able to bear or endure when high temperature resistant, anti-corrosive, combustion erode wear away.


The classification of rubbish incinerator reachs a characteristic. Collect sends life rubbish incinerator automatically makings, cent sieve, dry, burn, remove dust, automata at an organic whole. Life rubbish incinerator basically adopts the measure of high temperature combustion, new and high technology that imposes broken bits of oxygen, automatic discharge 2 times, monitor a demand in order to satisfy what sewage discharges. Rubbish burns the application that the technology is in abroad and the history that develop to already had a few years. Relatively mature furnace include furnace of aerification of the carbonization that heat up solution, pulse to cast furnace incinerator, mechanical furnace incinerator, rotate incinerator and CAO incinerator. Furnace of aerification of the carbonization that heat up solution basically uses the technical design such as hot solution, carbonization, aerification. Rubbish produces chemical reaction below the action of the temperature inside furnace and vapor, rubbish is complete carbonization, CO of final generation carbon monoxide can burn gas; Whole reaction process is finished in environment of oxygen of be disgusted with, avoided heavy metal effectively create condition and environment.
Can light gas to be able to pass smooth copy the purifying device refrigeration such as double standpipe, washer, de-acidification, remove dust wait for means to replace natural gas directly. Only station handles ability: 50-200 ton / day (much stage parallel can raise processing capability) , in applying to, rubbish of little city life is handled. Mechanical furnace discharges the working principle of incinerator: Rubbish is entered through feed hopper tilt the furnace platoon that be down. Because furnace discharges the crisscross motion between, rubbish is down to drive, make rubbish ordinal each area that go up through furnace platoon, till furnace the platoon is lighted. Combustion air discharges bottom to enter from furnace, mix with rubbish; High temperature flue gas heats through boiler face generation heats up vapour, flue gas is cooling. Finally, flue gas of flue gas classics handles the eduction after device is handled. The working principle of fluid-bed incinerator: Body of heater by poriferous distributing board composition. A large number of quartz are joined inside furnace arenaceous, quartz arenaceous heat to 600 ℃ above, the hot air of 200 ℃ above is beaten in hearth, make heat up arenaceous boiling, throw rubbish next. Rubbish and heat are arenaceous boil together, rubbish is rapid and dry, catch fire, combustion. A few medium slag and quartz are arenaceous remand through hoist continue to use inside furnace. Above is the fundamental of life rubbish incinerator and characteristic. You might as well add attention and understanding more.
How to choose the fireproof material of rubbish incinerator? Recently, a lot of clients sought advice from the fireproof material of rubbish incinerator. Select an issue in view of what the client is faced with, fireproof data small side arranged annulus in relief industry rubbish incinerator is fireproof material detailed list, offer reference only. The incinerator of different type differs according to type, temperature, position, the choice is different also, ask careful reference. Common incinerator includes intermittent incinerator, furnace Bi incinerator, CAO to burn incinerator of system, fluid-bed, circumgyrate furnace incinerator. Does the fireproof material of rubbish incinerator have: of the following characteristic?

Different incinerator, different use position, different use temperature, the following proposal offers reference only: The housetop of firebox. Sidewall. The use temperature of burner is 1000-1400 ℃ , can choose the tall aluminous brick of fireproof 1750-1790 ℃ and argillaceous brick, also can choose fireproof 1750-1790 ℃ but plastic; Of furnace Bi side on, next medium, use temperature are 1000-1200 ℃ , can choose carborundum brick or fireproof sex to be the argillaceous brick of 1710-1750 ℃ , also can choose wear-resisting pouring makings; The housetop of 2 firebox. Sidewall uses temperature to be 800-1000 ℃ , can choose fireproof sex the argillaceous brick under 1750 ℃ or clay are pouring makings; Bottom of housetop of housetop of hot exchange room, room of sidewall, eject, sidewall, room uses temperature under 600 ℃ , can choose fireproof sex the argillaceous brick under 1710 ℃ or clay are pouring makings; Adjust the use temperature of flue and flue is 600 ℃ , can choose fireproof sex the argillaceous brick under 1670 ℃ or clay are pouring makings.
Above incinerator is fireproof the choice of material should decide according to particular case. The incinerator of different type should run the most severe case in the process according to equipment, combine all sorts of elements. Rubbish incinerator the choice of line material, above all according to furnace temperature, the choice is fireproof material and can bear burn the heat-insulating material of temperature: Next, the product after must considering to burn is right of lining corrode. For example, when burning waste liquid of caustic soda sex, when the temperature inside furnace is as high as 1000 ℃ , na- is discharged with oxidation natrium gas, the SiO2 composition in firebrick and Na2O are united in wedlock, generation low melting point is mineral, gather in firebrick surface and erode. For example, firebrick is a kind of tall aluminous brick. Although SiO2 part is less, but the reaction as a result of alumina and oxidation natrium, the aluminous acerbity natrium in intermediate body can issue generation to expand in high temperature interstitial, make firebrick organization fragile change. Accordingly, the choice contains the tall aluminous fireproof material of tall alumina, or sex of choice alkali resistance is caustic the fireproof material of better chromic magnesium, magnesium and aluminium magnesium. For counteractive salt alkaline the osmosis that waits for medium and erode, improve data be able to bear or endure broken bits sex, choose the material with lesser porosity commonly. When igniting alkalescent liquid waste, the alkalescent melt content in igniting a product is had to common clay firebrick very strong caustic, because this should choose alumina content tall tall aluminous brick or alkali resistance are caustic better chromium is magnesian. Magnesia brick and aluminium magnesium are fireproof skill. For counteractive salt alkaline wait for medium immerse and corrode, improve data be able to bear or endure broken bits sex, often should choose hole to lead lesser material.
Stove is fired in the choice when fireproof skill, the temperature that should notice to place differs inside furnace and corrode a circumstance. Evidence book is different the obtain employment premise of place is the data that uses different social estate. If ignite the room is the most intertropical degree for 1400~1600 ℃ , can choose the corundum brick that contains Al2O3=90% ; Dry temperature is 900~1000 ℃ on furnace, awl ministry sets waste liquid nozzle. Can choose the brick of one class tall aluminium that contains Al2O3>75% ; Mid temperature is the chamber of a stove or furnace 900 ℃ , alkaline liner of salt of Dan Rong be in harmony is despicable, lining is cankered and inferior, can choose one course premise of obtain employment of the chamber of a stove or furnace of tall aluminous brick and the chamber of a stove or furnace are mid and different. There are a large number of melts in should igniting a product when salt is alkaline, melt material can gather on brae.
When choosing incinerator liner material, the temperature that still should notice to place differs inside furnace and corrode a circumstance, can choose the material of different grade. Highest temperature is firebox 1400~1600 ℃ , can choose the corundum brick that contains Al203=90% ; Temperature of job of upside of the chamber of a stove or furnace is 900~1000 ℃ , awl ministry sets waste liquid nozzle, can choose the tall aluminous brick that contains Al2O3>75% , mid job temperature is the chamber of a stove or furnace 900 ℃ , have lower reaches of a river of lining of melt salt alkaline edge, corrode serious, can choose brick of one class tall aluminium; Requirement of work of bottom of the chamber of a stove or furnace and the chamber of a stove or furnace are mid and basic identical, a large number of melt should be contained in combustion product when salt is alkaline, retention period gathers to grow on Yi Zaipo, in firebrick of easy also infiltration, if have,corrode when Na2CO3 more serious, because this is midder than the chamber of a stove or furnace poorer, should choose hole to lead inferior compact material, goods of firebrick of the frit that be like report. Incinerator is fireproof in material, the fireproof material that contains oxidation chromium has good corrosion resistance; When 1250 ℃ above, can use chromic corundum brick to regard incinerator as liner.
