The superheated steam of high-quality, improves generating efficiency.Wherein, the superheated steam of high-quality: therefore system flue-gas temperature is unstable and on the low side,
Flue dust adhesive property is strong, and traditional design can not design superheater, can only produce saturated vapor, can reach by this kind of technical scheme boiler
To the stable superheated steam pressure and temperature of design, improve generating efficiency, meet the reliable requirement of user's economic stability.
The work process of the present invention: the flue gas of about 500～650 DEG C is entered water-cooling sedimentation room, flue gas by rotary kiln outlet
Carrying out heat exchange by radiation, convection current with fin panel casing, partial fume dust is directly flushed on water cooling smoke baffle plate, and flue gas occurs
Turning to, mine dust granule heavier in flue gas falls directly into ash bucket；Big cavity flue gas uses low flow velocity design, it is simple to mine dust
Grain sedimentation；Owing to water-cooling sedimentation room flue-gas temperature is higher, at water-cooling sedimentation room top layout high temperature superheater, it is simple to it is overheated to ensure
Device outlet steam temperature；Water-cooling sedimentation room exhaust pass enters body of heater smoke inlet by connecting flue, smoke inlet enter vertical cigarette
Road, flue gas carries out heat exchange by radiation, convection current with fin panel casing, and mine dust granule heavier in flue gas falls directly into ash bucket；Greatly
Cavity vertical gas pass flue gas uses low flow velocity design, it is simple to mine dust granule settles；Drop to the horizontal cigarette of flue gas entrance of about 450 DEG C
Road, mine dust therein, by action of gravity, gradually falls in ash bucket, reaches further dustproof function, flue gas elder generation transversal flow level
In flue, low temperature superheater, in, low temperature superheater pipe be provided with resistant to elevated temperatures wearing-resistant tile windward, superheater tube can be reduced
Abrasion.The flue gas dropping to about 400 DEG C enters first, second and third section of vaporizer of horizontal flue, first and second economizer and deoxygenation steaming
Sending out device, the horizontal punching groove shaped heating surface tube of flue gas, carry out heat exchange, every section of heating surface uses variable flow cross-section design, improves heat transfer
Efficiency, thus improve the utilization rate of steel, flue-gas temperature is finally down to about 180 DEG C, is discharged into next from exhanst gas outlet
Procedure.In horizontal flue, flue gas mean flow rate is at about 8m/s, and sweep of gases heating surface has self deashing effect.
According to above-described embodiment, the present invention just can be realized well.What deserves to be explained is, before designing based on said structure
Put, for solving same technical problem, even if some made in the present invention are without substantial change or polishing, used
The essence of technical scheme still as the present invention, therefore it should also be as within the scope of the present invention.
