The superheating device comprises a superheater and a coal economizer, wherein the superheater comprises a superheater inlet collecting box, a superheater pipe piece and a superheater outlet collecting box; the coal economizer comprises a coal economizer inlet collecting box, a coal economizer pipe piece and a coal economizer outlet collecting box; and the coal economizer outlet collecting box is provided with a bypass pipeline with a valve to be communicated with the superheater inlet collecting box. The superheating device capable of regulating the steam temperature of the boiler can be applicable to the great change of the flue gas quantity of the boiler and precisely greatly regulates the steam temperature or maintains the stable steam temperature substantially.
Description
Technical field
The utility model relates to a kind of superheater of scalable boiler steam temperature.
Background technology
Convection-type desuperheater or direct-contact desuperheater are adopted in the adjusting of boiler superheater vapor (steam) temperature usually, through regulating discharge or injection flow rate, reduce the temperature of superheated steam.Both can only reduce the temperature of superheated steam, can not improve vapor (steam) temperature.
In service at boiler of power generation by waste heat high-temperature flue gas occurs sometimes or hot-gas temperature sharply changes, and it is low or too high to cause vapor (steam) temperature to be crossed, the operation function of the generating equipment that influence matches, or cause occurring security incident such as lack of water.
Summary of the invention
The utility model technical problem to be solved is to the deficiency that prior art exists, to design a kind of superheater of scalable boiler steam temperature, the vapor (steam) temperature that can regulate superheater significantly.
The technical scheme of the utility model is; A kind of superheater of scalable boiler steam temperature comprises superheater and economizer, wherein; Superheater comprises superheater inlet header case, superheater section of jurisdiction and super-heater exit case; Economizer comprises economizer inlet header case, economizer section of jurisdiction and economizer exit collection case, it is characterized in that, the bypass line that economizer exit collection case is provided with the band valve is communicated to superheater inlet header case.
Below the utility model is done to describe further.
Said superheater also comprises evaporimeter; And evaporimeter comprises evaporator collection case, evaporimeter section of jurisdiction and evaporator outlet collection case; The bypass line that evaporator outlet collection case is provided with the band valve is communicated to superheater inlet header case; The bypass line that economizer exit collection case is provided with the band valve is communicated to evaporator collection case, and said superheater section of jurisdiction, economizer section of jurisdiction and evaporimeter section of jurisdiction constitute the combination heat-transfer pipe.
Said combination heat-transfer pipe is the compound section of jurisdiction that superheater coil tubes, economizer coiled pipe and evaporimeter coiled pipe are formed.
Said combination heat-transfer pipe is hot device coiled pipe, an economizer coiled pipe and evaporimeter coiled pipe horizontal interlaced arrangement in flue.
Because the combination heating surface can all convert superheater surface into; Therefore can increase substantially the vapor (steam) temperature of superheater; Again because evaporimeter can convert economizer into; The area of superheater accounts for less ratio in the combination heating surface, therefore can reduce the vapor (steam) temperature of superheater significantly.
Known that by above the utility model can adapt to the variation significantly of boiler smoke amount as a kind of superheater of scalable boiler steam temperature, vapor (steam) temperature is stablized in adjusting or maintenance significantly accurately.
