Sensing heating overheating device for steam heat storage device

Abstract

The invention discloses a sensing heating overheating device for a steam heat storage device. The sensing heating overheating device comprises a steam heat storage device, a steam inlet switch and a connection pipeline. The sensing heating overheating device is characterized by being composed of a steam collecting disc, a sensing heating pipe, a heat insulation layer, a superheater outer wall, a temperature controller, a coil, a steam distribution disc and the like. The sensing heating overheating device is communicated with a steam heat storage device through a connection pipeline, and the steam inlet switch is arranged on the connection pipeline. Steam output by the steam heat storage device is heated by the sensing heating overheating device, and overheating steam is produced to be supplied to a power generator to generate power. The sensing heating overheating device utilizes sensing heating, is fast in heating speed, high in efficiency, small in energy consumption, easy in control of heating temperature and capable of avoiding overheating. No impurity is mixed in the heating process, and heating engineering automation is easy to achieve.

Description

technical field [0001] The invention relates to an induction heating device, in particular to an induction heating superheating device for a steam heat accumulator. Background technique [0002] In recent years, many boilers in my country, especially large-capacity domestic, imported and imported power generation boilers, have experienced superheater overheating explosion accidents due to large thermal deviations during operation. In a power plant, a burst tube in a boiler can cause millions in economic losses. When the steam temperature rises to the point where the pipe wall temperature exceeds the allowable temperature of the pipe steel, an over-temperature pipe burst accident will occur. Because the calculation accuracy of thermal deviation in boiler design is not high, there are many tube burst accidents in superheaters in power plants and boilers. In addition, the thermal efficiency of the boiler is low, the steam supply pressure fluctuates greatly, the labor intensit...
