Coke oven temperature continuous measuring method

Abstract

The invention offers the device and method used to continuously measure coke oven temperature of contactless. Its main technique features are as follows: the bottom of the chamber is set temperature hole; the top of the temperature hole is set temperature target; and the bottom is set temperature probe; the temperature probe is used to collect infrared light signal. And the light signal is converted to electronic signal by optoelectronic converter and treated by signal processor. The invention has the advantages of low cost, long useful life, high precision, and continuous measurement.

Description

Technical field: [0001] The invention relates to a device and method for measuring coke oven temperature, in particular to a device and method for non-contact continuous measurement of coke oven temperature. technical background: [0002] In coke production, it is necessary to measure the temperature of the coke oven and control the oven temperature according to the measured data. The production process of coke is essentially the process of controlling the firing temperature and time of coke. The continuous and accurate measurement of the coke oven temperature is the basis for realizing the ideal control of the coke oven temperature. It is of great significance to improve coke quality, increase coke production, reduce energy consumption, and reduce environmental pollution. At present, there are two methods that are most commonly used. One is a portable radiation thermometer, which is manually operated and measured at the top of the furnace every four hours. According to the...

Problems solved by technology

The furnace cover must be opened during measurement, which is inconvenient to operate

Due to the long temperature measurement interval, the temperature measurement time and temperature measurement location will have a great impact on the temperature measurement data, especially in snowy, rainy and windy weather, the measurement will be more inaccurate, so this method is difficult to achieve the ideal automatic control of the furnace temperature

[0003] Second, the furnace top is equipped with thermocouples for continuous temperature measurement. Generally, thermocouples are long and expensive. In addition, due to the presence of corrosive gases in the coke oven site, the temperature measurement environment is harsh, and the life of the thermocouples is short, resulting in excessive temperature measurement costs. At the same time, it also increases the difficulty of coal cleaning on the top of the furnace

Therefore, it is difficult for enterprises to accept
