Heating furnace belongs to one of hot project facilities, liner is formed by fireproof material, cent is boarding and indeterminate form, detailed introduction looks please below. A. Boarding is fireproof fireproof material weighs material figuration namely qualitative firebrick, light qualitative firebrick and heat preservation brick, pledge firebrick is given priority to with fireproof sex again, with the combustion path at burner, temperature room of radiate of higher heating furnace greets igneous face liner. Light qualitative firebrick holds concurrently have fireproof sex and heat preservation sex, multi-purpose the sidewall at furnace and roof. The hear resistance of heat preservation brick is very low, multi-purpose at the liner inside hearth and parietal, dosage is not much. B. Fireproof material points to blame figuration to be mixed with water by aggregate and cement commonly, elephantine concrete in that way the amorphous fireproof material of construction, abbreviation is pouring makings. Cent is give priority to with fireproof sex, what have certain heat preservation sex is pouring makings (pledge again pouring makings) with heat preservation model pouring makings (pledge gently) , construction method has infuse, daub and gush to wipe 3 kinds. To running type heating furnace, give priority to with fireproof sex, have certain heat preservation sex but model is pouring makings, use at roof, sidewall and hearth. In flue and chimney liner and parietal liner, use heat preservation sex but model is pouring makings. Contented fine piece, besmear also belongs to cliff cotton felt, Tao Qianpen blame finalize the design fireproof material. The structural feature of heating furnace tubal form, application and furnace of type of canal of safe use level are mixed by heating furnace noumenon more than heat reclaims systematic composition, the setting inside body of heater of heating furnace tubal form has chimney plate washer, heating furnace noumenon has export of high temperature flue gas at setting of lower part of chimney plate washer, also have very high demand to the use of fireproof material. More than heat reclaims the system includes air intake air heater, its feature depends on: Air intake air heater is comprised two paragraphs by intake air heater of air of blame condensation type and intake air heater of condensation type air. Manage the construction of type resistor furnace: Appearance of furnace of resistor tubal form shows the cylinder of one horizontal buy, it installs the bed that park makes by thin stencil steel to go up. Furnace casing encircles solder with thin stencil steel and become, atelier runs form the chamber of a stove or furnace for what fireproof material makes carborundum or alumina, the surface outside the chamber of a stove or furnace is made have gyroidal monofilament chamfer, aluminium alloy silk circles Tie Ge within filar chamfer. The heat group that two end make with fireproof material secures the chamber of a stove or furnace to go up at furnace lid. Material build by laying bricks or stones waits to build with siliceous aluminous fireproof fiber between the chamber of a stove or furnace and furnace casing for heat-insulation layer. Provide the applied range of type resistor furnace: Furnace of resistor tubal form makes chemical analysis, physics determine for the unit such as lab, industrial and mining enterprises, scientific research reach thermocouple calibrating to wait heat with. Single pipe decides carbolic furnace to be heating element with silicon kryptol, use at the analysis, determine when carbon and sulfur content are being contained in common steel or alloy steel, heat with. This series is in charge of type resistor furnace to be electric stove of periodic work style, can wait for unit, lab and car intercrop chemical analysis, physics to determine to wait with thermocouple appraisal for industrial and mining enterprises, scientific research heat with. The safety of furnace of resistor tubal form uses: Phonic, smooth alarm box and safe and interlocking protector are installed in crucial position, ensure safe, establishment of its equipment safety reachs the safe level that the country sets, include: (1) overheating is broken call the police occasionally reach protection; Aerate unusual; Ground connection protection; Short circuit protection. (2) furnace lid closes close, vacuum to spend contented requirement, fang Keqi is moved heat. (3) if thermocouple ruptures or overheating of the temperature inside furnace, criterion furnace stops automatically to heat. (When 4) facilities cuts off the water supply, furnace stops automatically to heat. (When pressure passing inside 5) furnace, a powerful person of safe pressure release is automatic pressure release, ensure the system moves safety. The heating furnace of type of canal of 3 kinds of configuration of liner of heating furnace of furnace tubal form is oil refine, petro-chemical with the craft heating furnace that uses in industry of chemical, chemical fibber. Its job principle is: The radiation room that fuel is providing type heating furnace (few number is in alone firebox) inside combustion, the quantity of heat that releases basically conducts heat through radiation and be in charge of to circulating heat delivers furnace, repass is conducted conduct heat and give medium be heatinged to circulating heat is delivered. The exterior heat loss due to radiation of heating furnace is concerning heating furnace thermal efficiency. And the stand or fall of effect of boiler setting heat preservation, affect the size of heat loss due to radiation of heating furnace directly. Accordingly, choosing good insulation material, advanced construction technology is one of heating furnace design important segment. The lining with contemporary commonly used heating furnace tubal form has 3 kinds of structures: Structure of bricky structure, fireproof fiber spray and pouring material composition. Lining of build by laying bricks or stones of brick of 1 brick structure is to use firebrick, include the lining that build by laying bricks or stones builds standard firebrick and different firebrick. Its advantage is OK differ according to heating furnace of requirement of the working temperature of place, work, thermic load different, the firebrick that chooses different sort, different property, different grade accordingly and fireproof slop. Its defect is the integral sex of lining and sealing difference, construction efficiency is low. Structure of spray of 2 fireproof fiber is fireproof fiber spray is to pass opportunity of special fiber spray, pretreatment medicinal powder high pressure of shape fiber cotton sends a spray gun, through a few at the same time special fluid carries equipment outer shroud of spray gun of even ground classics will be inorganic bond gush enters fiber cotton in, both go up to furnace wall in eject of an organic whole of the blending outside the gun. The advantage of technology of construction of fireproof fiber spray is construction speed fast, liner does not have juncture, air-tightness is good, special the construction that applies to place of pair of complex, different boiler setting. Its defect is: (1) lining intensity is low, in use process be destroyed easily by mechanical power;(2) fights air current to erode ability is poorer the abominable, influence quality that gets factitious factor does not stabilize;(3) construction environment, make sure equipment is running the effect in using hard. 3 pouring material composition is pouring material composition basically is by heat-resisting concrete, pouring the lining of the fireproof material build such as makings. Its are main the advantage is lining whole sex and air-tightness good, lining life is tall, construction of easy implementation mechanization works, construction efficiency is tall. Its defect is fireproof material is used inside period of efficacy, lining is repaired not as agile as lining of bricky build by laying bricks or stones. 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.
