Embodiment Construction

[0008] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0009] As shown in Figure 1 and Figure 2, the present invention includes a wall, a gas preheating loop and a combustion air preheating loop, the gas preheating loop 2 and the combustion air preheating loop 5 are vertically staggered and placed in the combustion In the device wall 3, there is a vertical gas outlet 21 and a spout 9 on the top of the vertical gas preheating loop 2. There is a gas inlet 1 connected to the vertical gas preheating loop on the wall 3. The upper part of the gas inlet is The vertical combustion-supporting air preheating loop 5 communicates with the combustion-supporting air inlet 4 outside the wall and the combustion-supporting air outlet 6 inside the wall, and there is an air nozzle 8 on the upper part of the combustion-supporting air outlet.

[0010] The entrances of the said vertical gas preheating lo...

Abstract

A ceramic flamer with better solution for uneven flame distribution, low utilization efficiency, waste of energy, short durability, pollution issue, comprises the fuel preheat ring and assistant burning gas preheat ring inside the wall of the burner, with the top of the fuel preheat ring having fuel output and top ejection opening, fuel inlet on the outside wall and fuel preheat ring vertical connection fuel input whose top having assistant air preheat ring, outside wall accessing to the assistant air inlet in perpendicular, inside the wall twisted up on the same ring with the fuel, the top location with gas ejection, and the fuel ejection forming into ring intersected distribution. It is unique and novel in structure, efficient in solving gas mixing, gas distribution, smoke preheat and other key issues.

Description

1. Technical field [0001] The invention relates to a combustion device, which is a ceramic burner with annularly arranged vertically upward nozzles. 2. Background technology [0002] The ceramic burner is an important equipment on the hot blast stove used in blast furnace ironmaking. Its performance directly affects the normal operation, efficiency and service life of itself and the blast furnace. The most commonly used structure in the hot blast stove is internal combustion. Type, external combustion type and top combustion type 3 types. But no matter which type of hot blast stove, ceramic burners with different structures are arranged. Existing ceramic burners have various structural problems, which will cause poor gas and air mixing and / or uneven airflow distribution in the hot blast stove, resulting in problems such as unstable combustion, poor regulation performance and poor flame distribution. . In this way, the load requirements and blast temperature requirements o...
