Background technology
In recent years, the many boilers of China, particularly jumbo domestic, import and Imported electricity generation boiler, being in operation superheater overtemperature demolition accident occurs too greatly because of thermal deviation.In power plant, a pipe explosion meeting causes millions of economic losses in the boiler.The overtemperature tube burst accident will occur 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 large, and labour intensity is large, the air feed of can not meeting an urgent need.At present, steam superheater generally adopts hot flue gas, but the flue gas superheater exists that temperature raising is slow, easily fouling, equipment maintenance cost are large, need the 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 large, and labour intensity is large, the steam supply of can not meeting an urgent need; The flue gas superheater exists that temperature raising is slow, easily fouling, equipment maintenance cost are large, need continued operation.
Technical scheme:
For addressing the above problem, the utility model comprises steam accumulator, admission switch, connecting pipe, eddy-current heating superheater, and 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 by connecting pipe and steam accumulator, and connecting pipe 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 closely is wrapped in the thermal insulation layer outer wall in the shape of a spiral.
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 by collection vapour dish and steam outlet pipe, and the lower end is connected by 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.
