Abstract
The utility model relates to a dual-reheating temperature adjusting device used for a tower-type boiler. A current tower-type boiler in use adopts a double-flue temperature-adjusting baffle for adjusting steam temperature of a reheating device, due to the uncertainty of the dust load of an outlet flue of a boiler economizer and the uncertainty of welding quality in field installation, large potential hazards exist because a flue and an ash hopper on the lower portion of the boiler economizer are hung by means of transmission of the temperature-adjusting baffle, and the temperature-adjusting baffle can distort to lose the effect when being stressed. The dual-reheating temperature adjusting device used for the tower-type boiler comprises a primary-reheat baffle (1) and a second-reheating baffle (2) which are installed in two flues (3) above a furnace tank respectively, the primary-reheating baffle is installed above an economizer A (4), the secondary-reheating baffle is installed above an economizer B (5), the economizer A is installed above a primary reheater (6), and the economizer B is installed above a secondary reheater (7). The dual-reheating temperature adjusting device is suitable for adjusting temperature for the tower-type boiler.
Description
technical field:
the utility model relates to a kind of register of the double reheat for tower boiler.
background technology:
the tower boiler used at present adopts the twin flue temperature-adjusting baffle to regulate the reheater steam temperature, and temperature-adjusting baffle is positioned in the economizer exit flue, and the economizer exit flue is divided into to upper and lower two parts flue.In traditional project organization, temperature-adjusting baffle directly is connected with the upper and lower part flue by bent plate, relies on temperature-adjusting baffle to hang underflue.Because boiler economizer exhaust pass dust load has uncertainty, the uncertainty of welding quality in on-the-spot the installation, rely on the temperature-adjusting baffle power transmission to hang the economizer underflue and there is very large hidden danger in ash bucket, the stressed meeting of temperature-adjusting baffle is distorted and ineffective.
summary of the invention:
the purpose of this utility model is to provide a kind of register of the double reheat for tower boiler.
above-mentioned purpose realizes by following technical scheme:
a kind of register of the double reheat for tower boiler, its composition comprises: single reheat baffle plate, double reheat baffle plate, described single reheat baffle plate, described double reheat baffle plate are arranged on respectively in two flues of burner hearth top, described single reheat baffle plate is arranged on economizer A top, described double reheat baffle plate is arranged on economizer B top, described economizer A is arranged on single reheat device top, and described economizer B is arranged on the secondary reheater top.
beneficial effect:
tower-type furnace of the present utility model top is divided into former and later two flues, and economizer, single reheat device and secondary reheater, according to different engine requests, are arranged in two flues according to actual conditions.Two flue tops are furnished with respectively controllable register.Be applied to the double reheat unit or reheat steam temperature regulated to the boiler that specific (special) requirements is arranged, can increase economy and the flexibility of unit operation.Being applied to 600MW grade unit net coal consumption rate compares the net coal consumption rate that can descend and is about 1.32g/kwh with the watering temperature adjustment mode.
the accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
accompanying drawing 2 is schematic diagrames that the utility model the first is installed.
accompanying drawing 3 is schematic diagrames that the utility model the second is installed.
the specific embodiment:
embodiment 1:
a kind of register of the double reheat for tower boiler, its composition comprises: single reheat baffle plate 1, double reheat baffle plate 2, described single reheat baffle plate, described double reheat baffle plate are arranged on respectively in two flues 3 of burner hearth top, described single reheat baffle plate is arranged on economizer A, piece number: 4 tops, described double reheat baffle plate is arranged on economizer B, piece number: 5 tops, described economizer A is arranged on single reheat device 6 tops, and described economizer B is arranged on secondary reheater 7 tops.
Claims (1)
1. the register of the double reheat for tower boiler, its composition comprises: single reheat baffle plate, double reheat baffle plate, it is characterized in that: described single reheat baffle plate, described double reheat baffle plate are arranged on respectively in two flues of burner hearth top, described single reheat baffle plate is arranged on economizer A top, described double reheat baffle plate is arranged on economizer B top, described economizer A is arranged on single reheat device top, and described economizer B is arranged on the secondary reheater top.
