Fluid-bed incinerator is equipment of a kind of efficient solid trash processing, because its operation temperature is tall, angry solid two-phase is acuteness mix, exist of caustic gas and grain content erode, very tall to the requirement of fireproof material. It is the option that fluid-bed incinerator uses fireproof data and applied point below:
1.Basically use place and the chamber of a stove or furnace of operating mode requirement: Need the fireproof data with shake of caustic of high temperature resistant, wear-resisting, heat-resisting and strong sex of the corrode that fight broken bits. Hearth and bottom area: Those who be faced with gas firm two-phase is intense erode and wear away, need has exceedingly good wearability and the stuff that heat-resisting pounds a gender. Roof and upside area: Higher temperature and wear away inferiorly requirement, need is high temperature resistant, be able to bear or endure the stuff that chemistry eats. Taphole and present makings opening: Temperature wave motion is big, performance of requirement heat-resisting shake is good.
2.Brick of tall aluminium of commonly used and fireproof material and aluminous silicate material: Fireproof material uses tall aluminous brick and aluminous silicate extensively at the different position of fluid-bed incinerator, especially the chamber of a stove or furnace and roof area. They are had good high temperature resistant gender and fight chemical aggressivity. Corundum radical is fireproof material: Corundum (Al₂O₃ ) fireproof material is used at temperature taller, wear away and erode more serious area, be like hearth and bottom area. Because its are tall,corundum base material expects hardness and fight thermal shock sex and special apply to this kind of environment. Carborundum (SiC) material: Carborundum material has good wearability and heatproof shake sex, commonly used the hearth at fluid-bed incinerator and other easy wear away place. SiC material still has good thermal conductivity, conduce to come loose quickly hot, reduce thermal stress. Wear-resisting is pouring makings: Wear-resisting is pouring makings suit to be used at hearth area or other get intense tatty place. These are pouring makings use tall aluminium, corundum or carborundum to serve as bases normally, the structure can maintain to stabilize below high temperature and resistance wears away. Compound and pouring makings: Compound and pouring expect through combining the advantage of different material, apply to a variety of abominable operating mode, be like high temperature and strong caustic environment. Special apply to the chamber of a stove or furnace and bed layer area.
3.Material choice and design should nod wearability: Choose wear-resisting material, if carborundum, corundum and wear-resisting are pouring,expect, enrage solid two-phase in order to answer erode and wear away. Fight thermal shock sex: In the place that temperature fluctuates often, if enter makings mouth and taphole, the choice has the stuff of sex of admirable and heatproof shake, be like tall aluminous brick or carborundum material. Be able to bear or endure chemical aggressivity: Because a variety of caustic gas and liquid state broken bits exist inside fluid-bed incinerator, material needs to have be able to bear or endure goodly soda acid sex and sex of the corrode that fight broken bits. High temperature intensity: The choice carries the data of intensity and stability below high temperature, the security that moves in order to ensure facility is long-term and stability.
4.Construction and defend a proposal accurate construction: Ensure fireproof material applies the packing of man-hour and uniformity, avoid occurrence crackle or weak area, influence service life. Regular examination and safeguard: As a result of the environment of high strenth work of fluid-bed incinerator, of fireproof material wear away inevitable, suggest to be checked regularly and be safeguarded, change in time or repair attaint area, in order to prolong integral service life.
5.New-style material and material of rice of technical application accept increase: Accept rice material is added in traditional and fireproof material, can raise the intensity of material, wearability and heatproof shake sex significantly. Take its natural course is peaceful pouring makings: Applied take its natural course is peaceful pouring makings, can raise the compact sex of construction efficiency and material, reduce hole rate, promote whole property.
Mix through logical choice use fireproof data, combine scientific design and construction technology, the service life that can improve fluid-bed incinerator significantly and moving efficiency, reduce moving cost.
