Embodiment Construction

[0030] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0031] Refer below Figure 1-Figure 10 The plasma jet nozzle 10 for boiler ignition according to the embodiment of the present invention will be described in detail.

[0032] Such as figure 1 and figure 2 As shown, the plasma jet nozzle 10 according to the embodiment of the present invention includes: a plurality of nozzle holes 1 arranged at intervals, and the plasma jet can be ejected through the nozzle holes 1 to achieve the purpose of igniting the boiler. Among them, when multiple streams of plasma jets are ejected from multiple nozzle holes 1 together, the energy and development range of the ejected plasma jets are larger, and the area of ​​the high-temp...

Abstract

The invention discloses a plasma jet flow nozzle for ignition of a boiler and the boiler. The plasma jet flow nozzle for ignition of the boiler comprises a plurality of spray holes, wherein the sprayholes are arranged at intervals. In this way, by arranging the multiple spray holes, the temperature of an obtained fire core can be higher, the range can be larger, and the ignition energy needed forpulverized coal firing can also be reduced to the greater extent.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a plasma jet nozzle for boiler ignition and a boiler with the plasma jet nozzle for boiler ignition. Background technique [0002] In related technologies, plasma is a quasi-neutral system composed of a large number of charged positive and negative particles and neutral particles. a state of matter. As the fourth state of matter, the temperature of plasma is high, the kinetic energy of particles is large, and its chemical properties are extremely active, and chemical reactions can occur at relatively low temperatures. These unique physical and chemical properties make it excellent in many fields. and technical advantages. Plasma jet ignition technology is developed by using high temperature, high speed plasma jet and its chemical effects. Because plasma ignition technology has the characteristics of high ignition energy, low ignition delay, high stability and good environmenta...
