Embodiment 1

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

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

[0079] Insert a thermocouple with a paperless recorder from the temperature measuring hole 113 of the small flue, and measure the exhaust gas temperature of the small gas flue 109 and the small air flue 110 on the machine side and the coke side of the No. 18 regenerator of the No. 1 coke oven. Perform on-line measurement, read the temperature of the small gas flue 109 and the small air flue 110 online at any time after commutating for five minutes, and co...

Embodiment 2

[0086] A group of coke ovens, numbered 6#7#, are 2×55 holes BS60-2 type 6m coke ovens. It is heated by blast furnace gas, the turnaround time is 19 hours, the standard temperature is 1260 / 1310 ℃, and the production is normal.

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

[0088] Insert a thermocouple with a paperless recorder from the temperature measuring hole 113 of the small flue, and measure the exhaust gas temperature of the small gas flue 109 and the small air flue 110 on the machine side and coke side of the No. 7 coke oven No. 100 regenerator. Online 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. ...

Embodiment 3

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

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

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

Abstract

The invention relates to the technical field of coke oven thermal adjustment, and specifically discloses a method for measuring and adjusting the temperature of a regenerator. The method is applied to the regenerative coke oven system, comprising the following steps: using a temperature measuring device to simultaneously measure the temperature of small gas flues and air flues with the same number; judging the heating mode of the regenerative coke oven system, and raising the temperature The opening of the adjusting flap of the high small flue is enlarged, and the opening of the adjusting flap of the small flue whose temperature needs to be lowered is reduced. If the coke oven system is heated by coke oven gas, the temperature difference is adjusted to the first temperature and Between the second temperature, if the coke oven system is heated by blast furnace gas, the temperature difference is adjusted to be between the third temperature and the fourth temperature. With the help of the above method, the two regenerators can preheat the rising airflow to a similar temperature, avoiding the impact on the pressure of the fire hole and the air coefficient in the combustion chamber, reducing the heat carried out by the exhaust gas, and improving the exchange rate of the regenerator. Thermal efficiency, improving the uniformity of coke oven straight-line temperature.

Description

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