Problems solved by technology

It can be seen that the traditional baking device has the following disadvantages: 1. The temperature monitoring and flow adjustment are not accurate during the baking process, which affects the baking quality; 2. The reasonable ratio of fuel to combustion air cannot be guaranteed. If the proportion of combustion air is too low, the fuel cannot Full combustion will not only waste fuel, but also pollute the atmosphere with black smoke from the flue. If the proportion of combustion-supporting air is too high, the heat loss will be large, which will not only waste heat energy, but also reduce the baking temperature; 3. The flue gas temperature is high, and the waste heat cannot be obtained. Utilization, not only wastes heat energy, but also damages air quality; 4. High requirements for operators and heavy workload

Abstract

The present invention discloses an automatic measurement and control method for the heating regenerative ladle comprising an automatic measurement and control method for ladle internal lining, an automatic measurement and control method for the smoke and dust density in the flue exhaust and an automatic measurement and control method for flue exhaust temperature. The present invention also discloses an automatic measurement and control method for the heating regenerative ladle comprising an automatic measurement and control method for ladle internal lining, an automatic measurement and control method for the smoke and dust density in the flue exhaust and an automatic measurement and control method for flue exhaust temperature; the present invention can ensure the sufficient burning of fuel and the heating quality of the ladle; the present invention can thoroughly remove the defect that the smoke and dust will pollute the environment and the energy-saving effect is obvious.

Description

technical field [0001] The invention relates to an automatic measurement and control method for baking heat storage type ladle and a device used in the method, which is suitable for both baking ladle and tundish. Background technique [0002] At present, the baking ladle and tundish usually use manual valves to artificially adjust the flow of fuel and combustion air. The monitoring of the baking temperature is usually to open the ladle cover to observe the color of the furnace lining. Some use a disposable thermocouple to measure the temperature. During the roasting process, the ratio of fuel to combustion-supporting air is generally determined by artificially observing the color of the flue gas. If black smoke is found, increase the flow rate of combustion-supporting air; The gas is discharged directly into the atmosphere through the flue. It can be seen that the traditional baking device has the following disadvantages: 1. The temperature monitoring and flow adjustment du...
