Whether the structural design of the burner is reasonable or not is directly related to the safe operation and the reaction efficiency of the gasification furnace, and the burner has a crucial influence on the overall performance of the gasification furnace.
Because the reaction temperature in the gasification furnace is high (more than 1500 ℃), the gasification pressure is high (4-6 MPa), and the gasification reaction is a violent chemical reaction between coal powder and oxygen, a large amount of fly ash particles and H can be generated 2 S, HCl, the end face of the burner is prone to cracking due to high temperature, abrasion and corrosion (as shown in fig. 1), which affects the service life of the burner, wherein the reduction of material properties due to high temperature is the main cause of burner cracking. Therefore, it is necessary to provide a cooling jacket on the outer layer of the burner to cool the end face of the burner.
The traditional burner cooling adopts a circulating cooling water jacket form, and cooling water enters the burner from a jacket inlet, absorbs radiant heat in the gasification furnace on the end surface and flows out from a jacket outlet. The cooling mode mainly depends on the convective heat transfer between the cooling water and the wall surface of the jacket, the heat transfer coefficient is low, and the end surface of the burner can not be cooled well. It follows that existing coal gasification burners remain to be improved.

The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In one aspect of the invention, a coal gasification burner is provided. A coal gasification burner according to an embodiment of the present invention is further described in detail below.
Referring to fig. 2, according to an embodiment of the invention, the coal gasification burner comprises: a burner channel 1 and a phase change cooling jacket 2. Wherein, the phase change cooling jacket 2 is sleeved on the burner channel 1. The phase change cooling jacket 2 comprises a shell 2-1 and an end plate 2-2, wherein the end plate 2-2 is arranged at the bottom of the shell 2-1; a heat exchange working medium (not shown in the drawing) and a capillary inner core 2-3 are arranged in the shell 2-1, and radiating fins 2-4 are arranged on the top and the upper side wall of the shell 2-1.
In the phase change cooling jacket 2, the heat exchange working medium has the following phase change heat exchange process: (1) the liquid working medium absorbs the radiant heat in the gasification furnace at the end part of the burner and evaporates into a gas state, (2) the gas working medium moves upwards to the upper part of the phase change cooling jacket 2, and (3) the gas working medium is air-cooled into the liquid working medium under the strong heat exchange action of the heat radiating fins 2-4; (4) the liquid working medium moves downwards under the combined action of the capillary force of the capillary inner core 2-3 and the gravity and returns to the end part of the burner. Therefore, through the four processes, the coal gasification burner disclosed by the invention realizes efficient heat exchange of the coal gasification burner by utilizing the characteristics of high heat exchange coefficient, high heat exchange strength and the like in the phase change heat exchange process.
The specific type of the heat exchange working medium is not particularly limited, and can be selected by those skilled in the art according to actual needs. According to some embodiments of the invention, the heat exchange medium is water. The boiling point of water is relatively low, and the water is easy to evaporate into a gaseous state after absorbing the heat radiation in the gasification furnace, and is easy to condense into a liquid state after being cooled on the upper part of the phase change cooling jacket 2, thereby completing the phase change cooling heat exchange. In addition, water is used as a heat exchange working medium, and the device also has the advantages of low cost, easiness in maintenance and the like.
According to some embodiments of the present invention, the inside of the phase change cooling jacket 2 is in a vacuum state. Specifically, the phase change cooling jacket 2 can be vacuumized before use, so that the boiling point of the heat exchange working medium is reduced, and the heat exchange working medium is further facilitated to realize heat exchange through phase change. It should be noted that the vacuum degree inside the phase change cooling jacket 2 can be determined according to the type of the specific heat exchange working medium. Example (b)For example, when the heat exchange working medium adopts water, the vacuum degree in the phase-change cooling jacket 2 is less than 10 -4 Pa. Therefore, the effect of phase change heat exchange of water as a heat exchange working medium is better.
According to some embodiments of the present invention, the height of the portion of the housing 2-1 provided with the heat dissipating fins 2-4 accounts for 30% to 40% of the total height of the housing 2-1. The inventors found that the heat radiation effect of the gaseous working medium moving to the upper part of the phase change cooling jacket 2 can be further improved by covering the heat radiation fins 2-4 on the upper side wall of the casing 2-1 within the above range. If the coverage rate of the radiating fins 2-4 on the upper side wall of the shell 2-1 is too low, efficient radiation of the gaseous working medium cannot be ensured; if the coverage rate of the radiating fins 2-4 on the upper side wall of the shell 2-1 is too high, excessive condensation of gaseous working media can be caused, the flow resistance is increased, and the heat exchange effect is further influenced.
Referring to fig. 3, according to some embodiments of the present invention, the burner channel 1 includes an inner channel 1a, a middle channel 1b, and an outer channel 1c, which are sequentially nested from inside to outside. Thus, different raw materials or gasifying agents can be supplied into the gasifier through the inner path 1a, the middle path 1b, and the outer path 1c, respectively, and the gasification efficiency in the gasifier can be further improved.
Further, the inner channel 1a has an inner channel inlet 1a-1, the middle channel 1b has a middle channel inlet 1b-1, and the outer channel 1c has an outer channel inlet 1 c-1. Thereby, the channels may be fed through the respective channel inlets.
According to some embodiments of the present invention, the inner channel 1a is an oxygen channel, the middle channel 1b is a coal water slurry channel, and the outer channel 1c is an oxygen channel. This improves the gasification efficiency of the gasification furnace.
In conclusion, the coal gasification burner disclosed by the invention adopts the phase change cooling jacket to replace the traditional circulating cooling water jacket, and high-efficiency and high-strength phase change heat exchange replaces the traditional convection heat exchange, so that the cooling effect of the heated end face of the burner is effectively improved, the working medium environment of the burner is improved, and the service life of the burner can be effectively prolonged. On the other hand, the coal gasification burner adopts the phase change cooling jacket to replace a circulating cooling water jacket, and further avoids a circulating cooling water pump and related pipelines, so that the investment of the system is saved, and the stability of the equipment is improved.
In another aspect of the present invention, a gasifier is provided. According to an embodiment of the invention, the gasification furnace comprises the coal gasification burner of the above embodiment. By adopting the coal gasification burner of the embodiment, the gasification furnace has the advantages of easiness in maintenance, high stability, low investment cost and the like.
The specific connection mode of the coal gasification burner and the gasification furnace is not particularly limited, and those skilled in the art can select the connection mode according to actual needs. Referring to fig. 4, according to some embodiments of the invention, the gasifier 3 is connected to the coal gasification burner by a flange 4. It is to be understood that only a partial structure of the gasification furnace 3 is shown in fig. 4.
