Technical field
The present invention relates to a kind of induction heating apparatus, particularly a kind of eddy-current heating superheater of steam accumulator.
Background technology
In recent years, the many boilers of China, particularly jumbo homemade, import and introduction type electricity generation boiler are in operation and superheater overtemperature demolition accident take place because of thermal deviation too greatly.In power plant, a pipe explosion meeting causes millions of economic losses in the boiler.The overtemperature tube burst accident will take place when vapor (steam) temperature is elevated to the allowable temperature that makes tube wall temperature surpass the pipe steel.Because the accuracy in computation of thermal deviation is not high in the boiler design, so the pipe explosion accident of superheater is a lot of in power plant and boiler.In addition, boiler thermal output is low, and the pressure of steam supply fluctuation is big, and labour intensity is big, the air feed of can not meeting an urgent need.At present, steam superheater generally adopts hot flue gas heating, but the flue gas superheater exist temperature raising slow, be prone to fouling, equipment maintenance cost big, need shortcoming such as continued operation.
Summary of the invention
The technical problem that solves:
Boiler thermal output is low, and air supply pressure fluctuation is big, and labour intensity is big, the steam supply of can not meeting an urgent need; The flue gas superheater exist temperature raising slow, be prone to fouling, equipment maintenance cost big, need continued operation.
Technical scheme:
For addressing the above problem, the present invention includes steam accumulator, admission switch, connect pipeline, eddy-current heating superheater, the eddy-current heating superheater comprises collection vapour dish, induction heating pipe, thermal insulation layer, superheater outer wall, temperature controller, coil, steam separating disk; The eddy-current heating superheater is connected through connecting pipeline and steam accumulator, connects pipeline and is provided with the admission switch.
Described superheater outer wall is equipped with temperature controller, and the inboard is provided with thermal insulation layer.
Described coil shape in the shape of a spiral closely is wrapped in the thermal insulation layer outer wall.
Described all induction heating pipes are equal to, and evenly vertically are distributed in the thermal insulation layer chamber.
Described induction heating pipe upper end is connected through collection vapour dish and steam outlet pipe, and the lower end is connected through steam separating disk and steam inlet pipe.
Described temperature controller comprises infrared radiation thermometer and converter plant etc.
Beneficial effect:
1, adopts steam accumulator, improved the thermal efficiency, keep supply gas pressure stable, save the labour, the steam supply of can meeting an urgent need;
2, adopt the eddy-current heating superheater, firing rate is fast, and efficient is high, and energy consumption is little, and heating-up temperature is easy to control, prevents burning;
3, adopt contactless mode of heating, in heating process, should not mix impurity, be easy to realize the heater process automation.

Described superheater outer wall 11 is equipped with temperature controller 12, and the inboard is provided with thermal insulation layer 10.
Described coil 13 shape in the shape of a spiral closely is wrapped in thermal insulation layer 10 outer walls.
Described all induction heating pipes 9 are equal to and evenly vertically are distributed in thermal insulation layer 10 chambeies.
Described induction heating pipe 9 upper ends are connected through collection vapour dish 8 and steam outlet pipe 4, and the lower end is connected through steam separating disk 14 and steam inlet pipe 15.
Described temperature controller 12 comprises infrared radiation thermometer and converter plant etc.
The concrete course of work is following:
The steam that boiler produces is stored in the steam accumulator 1; Saturated vapor gets into through steam accumulator venthole 2 and connects pipeline 18; Get into steam inlet pipes 15 through superheater air intake 16 again, heat in each induction heating pipe 9 of entering that saturated vapor is disperseed through steam separating disk 14 then, the superheated steam that heat through make collect 8 gatherings of vapour dish after; Get into steam outlet pipe 4 and get into external pipe, feed generating set at last and generate electricity through superheater venthole 5.In the process of heating, the infrared radiation thermometer in the temperature controller 12 can be monitored superheated steam in real time, and changes temperature through the converter plant regulating frequency.Eddy-current heating temperature raising cooling is easy to control rapidly, prevents burning and causes booster.
