Background technology
The gasification technology of air flow bed is meant carbon compound is passed through nozzle with vaporized chemical and stream, in gasification furnace, carries out the technological process of flame type non-catalytic partial oxidation reaction.The gasification of air flow bed is carried out under high-temperature and high-pressure conditions usually, and on-stream pressure is 3.0～6.5MPa, and operating temperature is 1300～1600 ℃.
Synthetic gas through the gasification furnace preparation has important value; One of be the raw material of liquefaction (directly or indirectly) made fuel oil, synthesizing methanol, ammonia and methyl ether etc., and the gordian technique of technology future developments such as the generating of integrated gasification combined cycle for power generation system, olefin production technology, fuel cell, reduction iron production and oil refining.The gasification hearth temperature is one of most important control parameters in the gasifying process of air flow bed, has only the gasification furnace operating temperature suitable, could improve gasification efficiency, the serviceable life of relevant device such as prolongation nozzle and refractory liner and material and smooth slag tap etc.
At present, the airflow bed gasification furnace of lining of fire brick structure mainly is to measure fire box temperature through the platinum rhodium thermocouple contact method of band protective casing.Yet thermopair at high temperature receives factor affecting such as airflow scouring, slag corrosion and refractory brick expansion, and its mission life is short and measuring accuracy is relatively poor.Even adopt the thermocouple wire or the protective casing of unlike material, fail all effectively to solve that its tolerable temperature is low, serviceable life short and problem such as measuring accuracy difference.In addition, because thermopair is installed or improper also will the causing of method of application measured the inaccurate of temperature, can't realize rational gasifying process process control.
Be the problem of avoiding above-mentioned thermopair contact method temperature element to exist, relevant indirect temperature-measuring method has also obtained certain utilization at the entrained flow bed gasification technology neighborhood.Such as the methane content that utilizes in the synthetic gas, through relevant methane temperature corresponding relation Model Calculation gasification hearth temperature.Because the accuracy of temperature measuring model and gas analysis utilizes methane content to be difficult to accurately obtain the gasification hearth temperature.For another example through measuring sonde turnover cooling range; Adopt indirect temperature-measuring methods such as heat transfer theory indirect temperature-measuring, CCD (Charge-coupled Device, charge coupled cell) image processing techniques thermometric and acoustic thermometry all owing to reasons such as system is complicated, measuring accuracy is lower fail extensively in the actual industrial device, to use.
Along with gasification with the decline of material quality, for example higher ash content and the ash fusion point of Geng Gao etc. in the coal for gasification, the airflow bed gasification furnace of employing water-cooling wall lining just progressively finds application.Because water-cooling wall lining airflow bed gasification furnace operating temperature generally all is higher than 1400 ℃, extreme temperature even surpass 1600 ℃, therefore traditional pyrometer couple can't use in water-cooling wall lining airflow bed gasification furnace.
In addition, because the water-cooling wall lining structure is complicated, can't satisfy the requirement that indirect measurement needs are offered a plurality of measured holes.And be deposited on the temperature measurement accuracy that molten slag layer on the measuring sensor will greatly influence measurement mechanism.The airflow bed gasification furnace of the water-cooling wall lining that has therefore now moved can only pass through gas composition, according to associated temperature Model Calculation gasification hearth temperature.But because the variation of gasified raw material quality and the influence of measurement precision of gas analyzer are calculated the temperature and the gasification hearth actual temperature that obtain and are differed bigger.
By on can know that under airflow bed gasification furnace high temperature and slag environment, existing measuring method also can't realize long period, online and accurate measurement gasification fire box temperature.Therefore need a kind of ability high temperature resistant, prevent slag deposition and measure accurately temperature measuring equipment and method and measure the gasification fire box temperature, realize the long-period stable operation of gas-flow bed gasifying apparatus.
