Description
Technical field
The utility model relates to a kind of compensation combustion type carbon monoxide waste heat boiler.
Background technology
Compensation combustion type carbon monoxide waste heat boiler is the corollary equipment of heavy oil catalytically cracking equipment, is mainly used in the high-temperature flue gas energy that reclaims catalytic unit and to CO in the high-temperature flue gas
2, CO, N
2, SO
2The recycling of afterburning processing procedure energy.The structure of domestic compensation combustion type waste heat boiler generally comprises mixed flue gas chamber, furnace bottom, burner hearth, furnace roof, water conservation section, superheat section, evaporator section, economizer section and exhanst gas outlet.
The mixed flue gas chamber comprises furnace wall, chimney arch and arch springing, the indoor hot cigarette temperature of mixed flue gas is about 500 ℃, and furnace wall divides internal layer and skin, and skin is selected for use common fire resistant heat preserving to water the material feeding cast and formed, internal layer adopts high-alumina refractory to water the material feeding cast and forms, and the furnace wall anchoring piece is selected Y shape bitch for use.Common high-alumina refractory waters Unit Weight and the thermal losses that material feeding has increased this position, and its iron-holder is generally high, in the running of boiler, when fire resistive material product runs into strong CO gas under 400 ℃-600 ℃, because CO decomposes, free carbon will be deposited on iron spot on the goods around, the goods disintegration is damaged.The position that shaft is 400 ℃-600 ℃ makes refractory product cracking and short texture for above-mentioned reasons, is one of key factor of furnace lining damage.Chimney arch selects for use the wedge shape clay brick to build by laying bricks or stones, it is poor to build globality by laying bricks or stones, after the process that puts into operation, because the erosion of body of wall and the factor of breathing, greatly reduce the life-span of chimney arch, because the reduction of chimney arch quality will directly have influence on the quality of furnace bottom, so the material selection at this position and structure are to produce the principal element that body of wall peels off, chimney arch caves in.
Furnace bottom is placed on the chimney arch, and furnace bottom is the well-regulated flat board that is covered with the square-grid hole, and it mainly is to distribute high-temperature flue gas.Drop-bottom thickness is generally about 200mm, domestic furnace bottom part is general to adopt the steel grid cast to form, globality is better, but in the actual moving process of boiler, because the inequality of temperature, make the non-homogeneous expansion of steel grid of entire arrangement, thereby the irregular crackle of furnace bottom base plate of cast is increased, part forms big crackle, causes the erosion of decline of bottom board bulk strength and bar-mat reinforcement, thereby shortens the service life of furnace bottom.
Burner hearth part wall area is big, the running temperature height, the domestic general internal layer of burner hearth materials for wall is selected chamotte brick or high-alumina brick for use at present, outer heat-barrier material is selected heat insulating brick for use, adopt the brick-supporting rack segment bearing, brick wall is provided with part drag hook brick, and dilatation joint stays the middle part that is located at brick wall, and furnace wall is not established dilatation joint for four jiaos.There is following point in selecting for use of the structural design of this body of wall and material: because the body of wall internal layer has been selected the heavy refractory material for use, the load of boiler steel structure and the thermal conductivity of body of wall have been increased, cause the outside overtemperature of boiler setting easily, simultaneously, be easy to generate the bulging and the crackle of furnace wall at positions such as four jiaos of furnace wall because drag hook brick and dilatation joint are provided with unreasonablely.All build at positions such as hearth combustor mouths in addition with brick, the brickwork construction at these positions, loosening easily and drop, influence the total quality of burner hearth.
The entire area of furnace roof is big, and the cast structure is generally adopted at this position, the furnace roof dilatation joint to stay the form of establishing with anchoring piece be the key of top quality.Dilatation joint is to adopt clamping plate to keep somewhere when cast, and anchoring piece adopts the form of reinforcing bar graticule mesh hanging structure.The dilatation joint that clamping plate are kept somewhere forms through-wall crack easily, anchoring piece adopts the integral grid structure to be unfavorable for refractory material breathing in use, and cause the generation of many irregular crackles, the irregular splitting that the penetrated crack of this dilatation joint and breathing form, because high-temperature flue gas corrodes, and cause the layering of top refractory material to come off, thereby cause top liner to be caved in.
Sealing place of water conservation section collection case; divide two places up and down; its primary structure is made of seal box and expansion joint; mainly constitute with ceramic fiber blanket and suspender member; this structure is very low because of ceramic fiber blanket intensity; boiler shake at this position in running is dropped easily, thereby causes this position overtemperature, directly influences the operation of boiler.
Superheat section, water conservation section, evaporator section and economizer section furnace wall lining generally adopt double-decker, and skin waters material feeding for light thermal-insulation; internal layer is common high alumina castable; anchoring piece is a Y type bitch, and this structure also can satisfy the requirement of boiler operatiopn, but this structure has increased the furnace wall load; after the boiler operatiopn simultaneously; the irregular crackle of furnace wall lining increases, and localized cracks is bigger, particularly economizer comb place; the gap is very little, and the maintenance of furnace wall lining is difficulty especially.
Summary of the invention
