Embodiment Construction

[0028] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0029] Such as Figures 1 to 3 As shown, the high-temperature superheater of the steam boiler includes a square body 1, the cavity of the body 1 is provided with an overheating tube 2, the overheating tube 2 is in the shape of a serpentine bent tube, and the number of overheating tubes 2 is 8-20. are set in parallel. The outer side of the main body 1 is also provided with two parallel main pipes 3, and the main pipe 3 is provided with a valve 7 which can block or communicate with the cavity of the main pipe 3. By setting the valve 7, it is convenient to open and close the main pipe 3, which is relatively easy to use. The advantage of convenience.

[0030] The two ends of the overheating pipe 2 protrude from the main body...

Abstract

The invention provides a high temperature superheater of a steam boiler, and belongs to the technical field of boiler components. The problem that an existing steam boiler cannot make heat of fuel be well absorbed and utilized is solved. The high temperature superheater of the steam boiler comprises a square body, a superheater pipe is arranged in a cavity of the body, and the superheater pipe is in a snakelike bent pipe shape. Two main pipes which are arranged in parallel are further arranged on the outer side of the body, the two ends of the superheater pipe both stretch out of the body, and the two ends of the superheater pipe are communicated with the middle parts of the two main pipes respectively. The side wall of the body is evenly covered with an insulating layer. The high temperature superheater of the steam boiler has the advantage of being capable of fully absorbing the heat of the fuel.

Description

technical field [0001] The invention belongs to the technical field of boiler components, and relates to a steam boiler, in particular to a high-temperature superheater of the steam boiler. Background technique [0002] The superheater is generally used in the boiler, and the high-temperature flue gas flows through the superheater, and the superheater is saturated or has a certain degree of superheated steam. The flue gas temperature is higher than the steam temperature in the superheater, so the flue gas transfers heat to the steam in the superheater. Let the temperature and pressure of the steam in the superheater rise to reach the design or required parameters. [0003] There are three types of high-temperature superheaters: radiation heat transfer, convective heat transfer, and combined radiation and convection heat transfer. Superheating: In layman's terms, boiling water continues to heat under atmospheric pressure to produce steam, which is saturated steam. That is ...
