Rubbish incinerator divides: Dream of type of comb with a double-edged fine-toothed comb of incinerator of city life rubbish, intermittent type incinerator, furnace burns furnace, rubbish platoon of incinerator of rubbish of industry of incinerator of hot solution aerification, fluid-bed type incinerator, rotary kiln type, furnace incinerator.
Because rubbish is phyletic various, cannot accomplish complete classification, the hot value of a quantity that brings about rubbish place to contain is different also. The property that keeps good is to need to consider the option of fireproof material from many sided below action of long-term high temperature to assure rubbish incinerator, incinerator mixes with firebrick of fireproof material cent pouring makings two kinds: Firebrick basically is mixed with argillaceous brick, tall aluminous brick carborundum brick is given priority to. Pouring makings pledge in order to stick earthy, tall aluminium but plastic with clay qualitative, carborundum pledges pouring makings give priority to. Because rubbish incinerator aggressivity is big, use pouring makings also be in ceaseless evolution, pledge with carborundum pouring tall aluminium of makings and phosphatic union is pouring makings increasing gradually, because of these two kinds pouring makings have good wear-resisting caustic sex.
The choice basis of fireproof material: Its operate different rubbish incinerator the condition is different, internal use temperature is different the performance that requires fireproof data is different also, should choose the fireproof material of different function with use temperature according to its work environment consequently. The use temperature of rubbish incinerator is in 1200 ℃ - 1400 ℃ . The gas when burning is right be able to bear or endure the aggressivity of material is stronger, hearth, propeller, side wall wears away and concussion sex is very big. So, the choice actors or actress qualitative liner also will change ceaselessly.
Choose fireproof material according to working environment, in the devoted place of rubbish incinerator, because the investment of litter is mixed,fall to need to be contacted with material, the temperature that throws a mouth at the same time often changes, ask fireproof material has good wearability and heat-resisting shake stability consequently, can choose argillaceous brick.
Inside the hothouse of rubbish incinerator and firebox, litter and lining issue direct contact in high temperature, on one hand slag will be adherent go up in lining, on the other hand foreign matter also can invade lining, at the same time the investment of litter causes the change of temperature necessarily, the requirement is consequently fireproof material not only wear-resisting, be able to bear or endure to adhere to corrode, hard, and fight even alkaline, fight oxidisability, choose clay commonly brick, tall aluminous brick, SiC brick, pouring expect and but plastic.
Choose fireproof material according to using temperature, different rubbish incinerator, different use position, use temperature is different: Its use the room top of firebox, sidewall, burner temperature is 1000-1400, can choose fireproof degree of tall aluminous brick that is 1750-1790 and argillaceous brick, also can choose fireproof spend those who be 1750-1790 but plastic.
Its use the upside of furnace Bi side, mid, bottom temperature is 1000-1200, can choose carborundum brick or fireproof degree of clay brick that is 1710-1750, also can choose wear-resisting pouring makings.
To be able to bear or endure the requirement of material must have the following:
One, with intensity the product with tall, strong wearability, will resist wear away and of strong air current erode;
2, must have acid-proof sex and stability, will resist acidity is eroded;
3, thermal shock sex also is the main factor that cannot ignore;
4, should have CO to erode, prevent lining material to burst apart;
5, choose heat-insulating material, want a foundation different situation, the capable person that selects light-duty heat insolation to fit each position more is qualitative.
The fireproof material that chooses rubbish incinerator should consider not only practical notice environmental protection even, save investment cost even, achieve burn efficiently technology, make contribution to protect bad situation.
