Embodiment 1

[0077]A group of coke ovens, numbered 1#2#, are 6m coke ovens of JN60-6F type with 2×55 holes. Coke oven gas is used for heating, the turnaround time is 19 hours, and the standard temperature is 1260 / 1310°C. The openings of the air inlet doors on the same side of the gas regenerator 105 and the air regenerator 106 are consistent, and the production is normal.

[0078] Further measurements and adjustments were made using the method of the invention. In this example, No. 1 coke oven No. 18 regenerator is selected for commissioning:

[0079] Insert a thermocouple with a paperless recorder into the temperature measuring hole 113 of the small flue, and measure the exhaust gas temperature of the gas small flue 109 and the air small flue 110 on the machine side and the coke side of the No. 18 regenerator of the No. 1 coke oven. Carry out online measurement, after five minutes of reversing, read the temperature of gas small flue 109 and air small flue 110 online at any time, compare ...

Embodiment 2

[0086] A group of coke ovens, numbered 6#7#, are 2×55 holes BS60-2 type 6m coke ovens. Blast furnace gas heating is used, the turnaround time is 19 hours, the standard temperature is 1260 / 1310°C, and the production is normal.

[0087] Further measurements and adjustments were made using the method of the invention. In this example, No. 7 coke oven No. 100 regenerator is selected for commissioning:

[0088] Insert a thermocouple with a paperless recorder into the small flue temperature measuring hole 113, and measure the exhaust gas temperature of the gas small flue 109 and the air small flue 110 on the machine side and the coke side of the No. 7 coke oven No. 100 regenerator. On-line measurement, after five minutes of reversing, read the temperature of the small gas flue 109 and the small air flue 110 online at any time, and compare the temperature difference between the small gas flue 109 and the small air flue 110 as the basis for on-site adjustment. After the measurement,...

Embodiment 3

[0096] The regenerative coke oven system of the third embodiment is basically the same as that of the first embodiment above, the difference between the two is that a simpler and easier-to-read plate thermometer is used for measurement.

[0097] In this embodiment, No. 86 regenerator of No. 2 coke oven is selected for commissioning:

[0098] Insert the disc thermometer into the small flue temperature measuring hole 113 to measure the exhaust gas temperature of the gas small flue 109 and the air small flue 110 on the machine side and the coke side of the No. 86 regenerator of the No. 2 coke oven. After five minutes, read and compare the temperature difference between the gas small flue 109 and the air small flue 110: the machine side is 21°C, and the coke side is 71°C. And the temperature at 20 minutes after reversing represents the temperature of the small flue before adjustment. The measurement results are shown in Table 3.

[0099] Because the temperature difference betwee...

Abstract

The invention relates to the technical field of coke oven thermotechnical regulation, and particularly discloses a method for measuring and regulating the temperature of a regenerative chamber. The method is applied to a heat accumulating type coke oven system and comprises the following steps: simultaneously measuring the temperatures of a small gas flue and a small air flue with the same serial number by using a temperature measuring device; judging the heating mode of the heat accumulating type coke oven system, expanding the opening degree of the adjusting turning plate of the small flue with the temperature needing to be increased, reducing the opening degree of the adjusting turning plate of the small flue with the temperature needing to be reduced, if the coke oven system adopts coke oven gas for heating, adjusting the temperature difference between the first temperature and the second temperature, and if the coke oven system adopts blast furnace gas for heating, adjusting the temperature difference value to be between third temperature and fourth temperature. By means of the method, the two regenerative chambers can preheat the upflow to the similar temperature, the situation that the pressure of the observation hole and the air coefficient in the combustion chamber are affected is avoided, heat brought out by waste gas is reduced, the heat exchange efficiency of the regenerative chambers is improved, and the uniformity of the straight movement temperature of the coke oven is improved.

Description

technical field [0001] The invention relates to the technical field of coke oven thermal adjustment, in particular to a method for measuring and adjusting the temperature of a regenerator. Background technique [0002] Such as Figure 1-Figure 3 As shown, modern coke ovens are equipped with regenerators, so they are called regenerative coke ovens. The regenerator chamber is filled with checker bricks, the upper part is provided with a storage roof space, and the storage roof is equipped with temperature and pressure measurement holes 104, the lower part is provided with a gas small flue 109 or an air small flue 110, and the upper part of the small flue is covered with grate bricks 111, that is, the roofing brick of the small flue is a grate brick 111, and a lattice brick is erected on the grate brick. The small flue is connected with an exhaust gas tray 112 (also known as an exchange switch). The exhaust gas tray 112 is composed of two forks and a valve body. The two forks ...
