Description

Steam-water thermal system of boiler

Technical Field

The utility model relates to a soda thermal technology detecting system, more specifically the utility model relates to a boiler soda thermal technology detecting system that says so.

Background

The boiler belongs to pressure-bearing equipment, and in the daily operation process, each pressure-bearing element is not only acted by high-temperature and high-pressure water vapor for a long time, but also bears the scouring of high-temperature flame and smoke dust, so that the problems of deformation, burning, abrasion, leakage and the like are easily caused. If the problems can not be solved in time, blockage and slag bonding are easy to occur in the boiler, and even serious accidents such as tube explosion and explosion can occur in serious cases; and the phenomenon of large narrow-point temperature difference of the boiler exists.

Disclosure of Invention

An object of the utility model is to provide a boiler soda thermal technology system to the above-mentioned problem that exists among the prior art.

The utility model discloses a realize above-mentioned purpose, the technical solution who adopts is: a boiler steam-water thermal system comprises an upper boiler barrel, a lower boiler barrel, an upper left header, an upper right header, a lower left header, a lower right header, a lower rear header, a lower front header, an economizer and an economizer, wherein boiler feed water directly enters the economizer, an outlet of the economizer is connected with the upper boiler barrel, the upper boiler barrel is connected with the lower boiler barrel, the upper left header, the upper right header, the lower left header, the lower right header, the lower rear header and the lower front header are connected with the upper boiler barrel, and the upper boiler barrel is connected with the economizer.

The economizer inlet is provided with an economizer inlet header, and the economizer outlet is provided with an economizer outlet header.

Compared with the prior art, the beneficial effects of the utility model are that:

the steam-water thermal system of the boiler increases the overall low-temperature heat, can avoid high energy and low use and reduce the narrow-point temperature difference of the boiler; and low-temperature waste heat in the industry can be recovered, and the utilization efficiency of energy is improved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure, an upper boiler barrel 1, a lower boiler barrel 2, an upper left header 3, an upper right header 4, a lower left header 5, a lower right header 6, a lower rear header 7, a lower front header 8, an economizer 9, an economizer 10, an economizer inlet header 11, and an economizer outlet header 12.

Detailed Description

The invention is described in further detail below with reference to the following description of the drawings and the detailed description.

Referring to fig. 1, a thermal detection system for steam and water of a boiler comprises an upper drum 1, a lower drum 2, an upper left header 3, an upper right header 4, a lower left header 5, a lower right header 6, a lower rear header 7, a lower front header 8, an economizer 9 and an economizer 10. The feed water from the boiler directly enters the coal economizer 10, the outlet of the coal economizer 10 is connected with the upper boiler barrel 1, and the upper boiler barrel 1 is connected with the lower boiler barrel 2; the upper boiler barrel 1 is connected with an upper left header 3, an upper right header 4, a lower left header 5, a lower right header 6, a lower rear header 7 and a lower front header 8, and the upper boiler barrel 1 is connected with an economizer 9.

Referring to fig. 1, an inlet of the economizer 10 is provided with an economizer inlet header 11, and an outlet of the economizer 10 is provided with an economizer outlet header 12.

Referring to fig. 1, in operation, boiler feed water enters an economizer 10 through an economizer inlet header 11, the economizer 10 absorbs heat from high temperature flue gas and heats the boiler feed water, and then the boiler feed water enters an upper drum 1 and a lower drum 2 through an economizer outlet header 12. The upper boiler barrel 1 and the lower boiler barrel 2 receive water from an economizer 10, carry out steam-water separation and steam purification on the boiler feed water, and supply water to a circulation loop; and the temperature of the exhaust gas is reduced by the economizer 9. The steam-water thermal system of the boiler increases the overall low-temperature heat, can avoid high energy and low use and reduce the narrow-point temperature difference of the boiler; and low-temperature waste heat in the industry can be recovered, and the utilization efficiency of energy is improved.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, above-mentioned structure should all be regarded as belonging to the utility model discloses a protection scope.
