CN102331307A - Coke oven straight temperature manual measurement method - Google Patents

Abstract

The invention relates to a straight temperature manual measurement method in the field of coke oven heating management. In the method, through measuring a standard flame path temperature and a substitution flame path temperature, compensation calculation is carried out on the substitution flame path temperature measurement value to obtain a corresponding standard flame path temperature, thereby realizing the purpose that full-oven standard flame path temperatures can be measured in an exchange period. A standard flame path is selected from middle regions at two sides of the coke oven and coke; and in order to reduce errors, a flame path adjacent to the standard flame path is generally selected as a substitution flame path. Compared with the prior art, the invention has the beneficial effects that the full-oven standard flame path temperature can be obtained through measurement of the standard flame path temperature and the substitution flame path temperature once, all standard flame path temperatures can be obtained within a coke oven exchange period, defects of the traditional straight temperature measurement method are overcome, the temperature management efficiency is increased, the labor intensity of workers is reduced, and the temperature measurement instantaneity is good.

Description

The manual temp measuring method of a kind of coke oven mean flue temperature

Technical field

The present invention relates to a kind of manual temp measuring method of mean flue temperature of coke oven heating management domain.

Background technology

The heating management of coke oven in the coke generative process is for reducing the coking energy consumption, and it is significant to improve converter life and stable coke quality.Mean flue temperature is meant the medial temperature of coke oven machine, coke side standard quirk, represents the medial temperature level of full stove, the heating of coke oven management with the mean flue temperature measured as the foundation of regulating gas flow.

Measured during at down current in back 5 minutes because mean flue temperature generally heats in the exchange of coke oven,, could accomplish the measurement of whole standard quirk mean flue temperature so, need twice exchange for complex thermal coke.Traditional mean flue temperature is measured and is adopted the thermometric mode just twice, so the temperature survey real-time is poor.

For realizing above-mentioned purpose, the present invention realizes through following technical scheme:

The manual temp measuring method of a kind of coke oven mean flue temperature; This method is through measurement standard fire path temperature and alternative fire path temperature; Through compensating the standard fire path temperature that correspondence is obtained in calculating to substituting the fire path temperature measured value, the realization coke oven is measured the standard fire path temperature of full stove in an exchange cycle; The compensation computing formula is following:

$\mathrm{\δ}=\frac{T_{\mathrm{CS}}-T_{\mathrm{PS}}}{N_{\mathrm{CS}}-N_{\mathrm{PS}}}(N_S-N_R)$ Formula (1)

T _S=T _R+ δ formula (2)

Described standard quirk is selected in the central region of machine, burnt both sides; Described standard quirk is selected in the central region of machine, burnt both sides; Alternative quirk is the corresponding standard quirk both sides quirks of even number quirk at interval, and the even number scope is 0,2,4.

In order to reduce error, substitute the adjacent quirk of the common choice criteria quirk of quirk.

Compared with prior art, the invention has the beneficial effects as follows:

This method is through one-shot measurement standard quirk and alternative fire path temperature; Can obtain full stove standard fire path temperature; Can in a coke oven exchange cycle, obtain whole standard fire path temperatures, remedy the deficiency of traditional mean flue temperature measuring method, improve temperature treatment efficient; Reduced labor strength, and the thermometric real-time is good.

Description of drawings

Fig. 2 is the coke oven plan structure figure of the manual temp measuring method of coke oven mean flue temperature.

Embodiment

The manual temp measuring method of a kind of coke oven mean flue temperature; This method is through measurement standard fire path temperature and alternative fire path temperature; Through compensating the standard fire path temperature that correspondence is obtained in calculating to substituting the fire path temperature measured value, the realization coke oven is measured the standard fire path temperature of full stove in an exchange cycle.

Shown in Figure 1 is the process flow diagram of concrete thermometric scheme, and Fig. 2 opens beginning position, standard quirk, substitutes quirk and thermometric order for thermometric in the present embodiment thermometric scheme.

This embodiment is a sample just, and thermometric time, thermometric open beginning position, standard quirk, substitute quirk can adjust by actual conditions.

The manual temp measuring method of a kind of coke oven mean flue temperature, concrete steps are following:

1) confirms the thermometric time

With reference to the manual thermometric mode of traditional mean flue temperature, be chosen in 0,4,8,12,16, the 20 point measurement mean flue temperature data of every day.

2) confirm that thermometric opens the beginning position

With reference to the manual thermometric mode of traditional mean flue temperature, select to begin thermometric from coke side switch end.

3) quirk that settles the standard

With reference to the manual thermometric mode of traditional mean flue temperature; Central region choice criteria quirk in machine, burnt both sides all can measure in order to satisfy single even numbers quirk simultaneously, therefore for 32 flues; We select 7, No. 26 quirks is the standard quirk, and the quirk position is with reference to Fig. 2.

4) the corresponding alternative quirk of quirk that settles the standard

In order to reduce error, the quirk that our selection standard quirk is adjacent is alternative quirk, and present embodiment selects 6, No. 25 quirks for substituting quirk.

5) confirm the thermometric order

With reference to the manual thermometric mode of traditional mean flue temperature; Measure the down current temperature after 5 minutes in exchange, so the standard quirk replaces thermometric with alternative quirk, first thermometric quirk needs according to on-site actual situations definite; Can be the standard quirk, also can be to substitute quirk.

6) will substitute fire path temperature and be compensated for as corresponding standard fire path temperature

Same firing chamber, from the pusher side to the coke side, flue temperature constantly raises, and the alternative quirk that present embodiment is selected is the last quirk of standard quirk, and therefore alternative fire path temperature adds compensation temperature and equals corresponding standard fire path temperature.

Compensation back standard fire path temperature computing formula is following:

$\mathrm{\δ}=\frac{T_{\mathrm{CS}}-T_{\mathrm{PS}}}{N_{\mathrm{CS}}-N_{\mathrm{PS}}}(N_S-N_R)$ Formula (1)

T _S=T _R+ δ formula (2)

Wherein, T _CSBe the standard temperature of coke side standard quirk, T _PSBe the standard temperature of pusher side standard quirk, N _CSBe the fiery Taoist monastic name of coke side standard quirk, N _PSBe the fiery Taoist monastic name of pusher side standard quirk, N _SBy the fiery Taoist monastic name of compensation standard quirk, N _RBe the fiery Taoist monastic name that substitutes quirk, δ is a compensation temperature, T _RBe the temperature that substitutes quirk, T _SIt is the temperature of compensation back standard quirk.

In exchange cycle of coke oven, measure whole down current standard quirks and alternative fire path temperature, it can be burner that thermometric opens the beginning position, also can be a platform, can begin thermometric from coke side, also can begin thermometric from pusher side; Thermometric opens the beginning quirk, and actual quirk airflow direction is definite constantly according to thermometric, can be the standard quirk, also can be to substitute quirk; Two coke ovens of a stove group can separate thermometric, also can unify thermometric; Can continuously carbonizing chamber thermometric during thermometric, also can fixed interval number carbonization chamber thermometric.
