Alternatively, in the above-described embodiments, the first water-cooling wall 11 is set in gasification furnace 1, lays resistance in the first water-cooling wall 11
Fire coating.
Specifically, the first water-cooling wall 11 is used for reducing gasification stove internal wall temperature, lays refractory coating, keep away outside the first water-cooling wall
When exempting from the reaction of the fine coal in gasification furnace, the first water-cooling wall 11 is directly exposed under thermal-flame, causes the phenomenon of decrepitate pipe.
Further, the first water-cooling wall 11 is provided with water inlet 111 and outlet 112, the direction of water inlet to outlet
For from bottom to top.
Specifically, during coal gasification equipment availability, its upper and lower relation is, gasification furnace 1 is positioned at the top, and centre is radiation waste
Pot 2, bottom is slag bath 3.Then the water inlet position 111 of gasification furnace 1 is in the lower section of gasification furnace 1, and outlet 112 is positioned at gasification furnace 1
Top.Such as, when operation, fresh water (FW) added the first water-cooling wall 11 from water inlet 111 and discharge from outlet 112, technique
Water is for lowering the temperature to the first water-cooling wall 11.In gasification furnace 1, after coal gasification reaction, the direction of gas and residue is autopneumatolysis stove 1
Top to the lower section of gasification furnace 1, and fresh water (FW) flow to lower section to the top of gasification furnace 1 for autopneumatolysis stove 1, with gas and residual
Flowing to of slag is in opposite direction.So carry out countercurrent flow, improve the heat exchange efficiency of the first water-cooling wall 11.
Further, gasification furnace 1 top is provided with igniter burner 12, and igniter burner is outside equipped with aqueous cold plate 13, aqueous cold plate

When change stove 1 works, from each coal dust burner 14, coal dust and the gasifying agent of fine coal being added gasification furnace 1, ignited burner 12 is lighted,
Start combustion reaction.Owing at least three coal dust burner 14 is peripherally disposed so that coal dust and gasifying agent are in gasification furnace
Occur violent rotating percussion to flow, enhance the mixing of coal dust and gasifying agent.Reacted molten condition slag is at centrifugal force
Being got rid of under effect on the first water-cooling wall 11, internal layer slag freezes into fixing slag blanket, plays a protective role the first water-cooling wall 11,
Outer layer slag flows downward along the first water-cooling wall 11, thus extends its time of staying in gasification furnace 1 so that unreacted
Carbon residue can react further, improves the gasification efficiency of gasification furnace 1.
Further, gasification furnace annular space 16, gasification furnace 1 housing are formed between housing and first water-cooling wall 11 of gasification furnace 1
On be provided with nitrogen inlet 17, nitrogen inlet is connected with gasification furnace annular space 16.Wherein, by nitrogen inlet 17 to gasification furnace annular space
Being filled with nitrogen in 16, the nitrogen being filled with defines one layer of sealing gland to gasification furnace 1, it is to avoid in stove, coal gas spilling gasification furnace 1 enters
Gasification furnace annular space 16, it is ensured that the operation safety of gasification furnace 1.
Further, be provided with in radiation waste pot 2 at least two-layer the second water-cooling wall 21, at least two-layer the second water-cooling wall 21 it
Between form coal gas baffling passage 23, radiation waste pot 2 is provided with gas exit 22, gas exit 22 and baffling channel connection 23.
Wherein, the coal gas produced after reaction in gasification furnace 1 flows through speed when gasification furnace 1 exports to be increased, and coal gas carries slag and enters spoke
Penetrate in useless pot 2, it is to avoid gasification furnace 1 outlet and radiation waste pot 2 inlet connection flow the blocking the most freely caused due to slag.Gas
When reacting the coal gas obtained in changing stove 1 with melted arrival below baffling passage 23, coal gas is up through baffling passage 23, and passes through
Being arranged on gas exit 22 output radiation above radiation waste pot 2 to give up pot 2, molten slag then falls in slag bath 3 due to inertia.Due to coal
Gas, when baffling passage 23 is up, with at least abundant heat exchange of two-layer the second water-cooling wall 21, reduces by gas exit 22 defeated
The gas temperature gone out, reduces the operating pressure of follow-up equipment.
Further, the second water-cooling wall 21 is provided with water inlet 211 and outlet 212, the direction of water inlet to outlet
For from bottom to top.
Alternatively, the fresh water (FW) in the second water-cooling wall 21 flow to give up upper to radiation waste pot 2 of the lower section of pot 2 for autoradiolysis
Side, with coal gas flow in opposite direction.So carry out countercurrent flow, improve the heat exchange efficiency of the second water-cooling wall 21.
Alternatively, coal gas generation in radiation waste pot 2 is repeatedly turned back flowing, after being fully contacted heat exchange with the second water-cooling wall 21
Export through gas exit 22.
Alternatively, the reaction pressure scope of gasification furnace 1 is 0-1Mpa, for fuel gas user and middle-size and small-size Coal Chemical Industry item
Mesh, is greatly reduced the manufacturing cost of equipment on the basis of meeting technological requirement.
