Description

Technical Field

[0001] The utility model relates to the technical field of coal combustion, in particular to an intelligent sensing and combustion stability device. Background Technique

[0002] Considering the conditions conducive to the stable combustion of pulverized coal, it is expected that the pulverized coal air flow can catch fire in time within a certain distance from the burner nozzle. Therefore, the flow of the pulverized coal air flow should be reasonably organized to form local high pulverized coal concentration, high temperature and appropriate oxygen concentration areas that promote the timely temperature rise and ignition of the pulverized coal air flow. When the boiler operates at low load, the coal feeding amount and pulverized coal concentration are greatly reduced, which increases the heat required for ignition of the pulverized coal air flow, delays the ignition position, and deteriorates the flame stability.

[0003] After retrieval, the text of the publication number "CN117704409A" mentions "a coal-hydrogen collaborative stable combustion device for a coal-fired power plant, including a mounting bracket; a combustion furnace is assembled on the mounting bracket; a hydrogen-oxygen generator is provided on the mounting seat, and a stirring component and a gas mixing component are assembled in the combustion furnace. It belongs to the technical field of coal combustion in coal-fired power plants. For this coal-hydrogen collaborative stable combustion device for a coal-fired power plant, through the arranged gas mixing component, when the stirring component is driven and the pulverized coal is stirred in the combustion furnace, the spiral blade sleeved outside the transmission shaft can rotate. When the spiral blade rotates, the hydrogen-oxygen gas in the combustion furnace can generate turbulence, and the generated air turbulence can increase the contact area between the pulverized coal and the hydrogen-oxygen gas, promote the diffusion and combustion reaction of the mixture, and then cooperate with the stirring of the pulverized coal by the stirring component to further improve the combustion efficiency of the pulverized coal, make the pulverized coal and the hydrogen-oxygen gas mix and burn more fully, and release more energy for coal-fired power generation". When it is used, during the coal-fired power generation process, through the speed reduction transmission between the reciprocating speed reducer and the motor speed reducer, and in cooperation with the transmission connection between the motor speed reducer, the power shaft and the stirring component, when the power shaft rotates, the arranged stirring disc can reciprocate in the combustion furnace. With the notch opened outside the stirring disc, the arranged stirring disc can rotate continuously in the combustion chamber and stir the pulverized coal. When the hydrogen-oxygen gas generated by the hydrogen-oxygen generator is introduced into the combustion chamber, through the stirring of the pulverized coal by the stirring disc, the arranged pulverized coal can be fully mixed with the hydrogen-oxygen gas, and the pulverized coal fully mixed with the hydrogen-oxygen gas can achieve a more complete combustion reaction. However, this combustion stability device cannot adjust the combustion degree, while the boiler needs to adjust the combustion, which reduces the practicability of the combustion stability device and does not meet the usage requirements of users.
