Problems solved by technology
The existing desuperheater has a certain limit on the degree of superheat of the steam. When the degree of superheat is small, the cooling water atomization time will often lead to instability of the temperature measurement point, which is not conducive to the normal operation of the equipment.

Embodiment 1
[0028] A nozzle assembly of a steam-assisted desuperheater is arranged on a main steam pipeline 1 and includes a nozzle 2 , a desuperheating water conduit 3 and a steam conduit 4 . The main steam pipe 1 is filled with process steam and defines an axial flow path of the process steam. The steam pipe 1 preferably has a circular cross-section in the form of an elongated pipe section axially extending from one end to the other end.
[0029] The desuperheating water conduit 3 and the steam conduit 4 radially penetrate the main steam pipeline 1, and the desuperheating water conduit is connected to the nozzle 2 for providing cooling water to the nozzle 2; the steam conduit 4 is connected to the nozzle 2 for to provide atomizing steam to the nozzles. The desuperheating water conduit 3 and the steam conduit 4 are arranged on the radially outer side of the main steam pipeline. The desuperheating water conduit and the steam conduit can be arranged approximately in parallel, and are fixed...

Description
technical field [0001] The present invention relates to a desuperheater structure. Background technique [0002] Desuperheaters are used in many industrial fluid and gas lines to reduce the temperature of superheated process fluids and gases to a desired set point temperature. For example, desuperheaters are used in the power industry to cool superheated steam. The desuperheater sprays a fine mist of atomized cooling water or other fluid into a steam tube through which process steam flows, and the evaporation of the water droplets in the fine mist lowers the temperature of the process steam. The existing desuperheater has a certain limit on the degree of steam superheat. When the degree of superheat is small, the atomization time of cooling water is long, which often leads to the instability of the temperature measurement point, which is not conducive to the normal operation of the equipment. Contents of the invention [0003] In order to solve the deficiencies in the pr...
