Embodiment Construction

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like figure 1 As shown, the present invention provides an energy storage device for heating flue gas at the tail of a boiler, comprising a first heater 4 connected to a flue 1 at the tail of the boiler, and the first heater 4 is used to receive the tail of the boiler The flue gas in the flue 1 exchanges heat with the first heat exchange medium to heat the first heat exchange medium. The outlet of the first heater 4 is connected to the high temperature first heat exchange medium inlet of the medium heat tank 5, and the medium The heat tank 5 is used to store the first heat exchange medium conveyed by the first heater 4, and the outlet of the high temperature first heat exchange medium of the medium heat tank 5 is connected with a second heater 8, and the medium heat tank 5 is connected with a second heater 8. 5. A first regulating valve 6 ...

Abstract

The invention discloses an energy storing device for heating tail flue gas of a boiler and an operating method. The energy storing device comprises a first heater, wherein the first heater is connected with a boiler tail flue, a first heat exchange medium is introduced into the first heater, the first heat exchange medium in the first heater and flue gas in the boiler tail flue are subjected to heat exchange heating, an outlet of the first heater is connected with an inlet of a medium hot tank, the medium hot tank is used for storing the first heat exchange medium for heat exchange heating, anoutlet of the medium hot tank is connected with a second heater, a first regulating valve is arranged on a pipeline, connected to the second heater, of the medium hot tank, the first heat exchange medium subjected to heat exchange heating in the second heater and a second heat exchange medium in a heat supply network are subjected to heat exchange, and the second heat exchange medium enters the heat supply network after absorbing heat. The energy storing device is suitable for meeting multiple heat supply demands of the heat supply network, improves peak load regulation capacity of the boiler, and has a wide application range, smaller improvement for the boiler body and low improvement cost, the whole device has a simple and flexible structure, and realization of industrialization is facilitated.

Description

technical field [0001] The invention belongs to the technical field of power station boilers and industrial boilers, in particular to an energy storage device for heating flue gas at the tail of a boiler and an operation method thereof. Background technique [0002] The development of urban industrial parks has led to an increase in the demand for steam or heat. At present, the society and the government are widely promoting the use of clean energy, and restricting the construction of coal-fired units and industrial boilers. There is a total amount of heating units or heating loads in industrial parks and residential users deficiency phenomenon. In addition, during the heating period in winter, residential users have less demand for heat load during the day and greater demand for heat load at night; most industrial parks also have cyclical changes in heat supply. This results in insufficient heating during the day to meet demand. [0003] The medium capacity expansion tran...
