Description
Technical field
The present invention relates to a kind of high temperature test probe, particularly relate to a kind of high temperature test probe for airflow bed gasification furnace, and comprise its device and method of testing.
Background technology
The gasification technology of air flow bed refers to carbon compound is passed through nozzle with vaporized chemical and stream, carries out the technological process of flame type non-catalytic partial oxidation reaction in gasification furnace.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 ℃.
The synthetic gas standby by gasifier system 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 the technique future developments such as the generating of integrated gasification combined cycle for power generation system, alkene production technology, fuel cell, reduction iron production and oil refining.The gasification hearth temperature is one of most important control parameter in the gasifying process of air flow bed, only has the gasification furnace operating temperature suitable, could improve gasification efficiency, the serviceable life of the relevant device such as prolonging 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 by the platinum rhodium thermocouple contact method with protective casing.Yet thermopair at high temperature is subjected to the 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 thermocouple wire or the protective casing of unlike material, all fail effectively to solve the problems such as its tolerable temperature is low, serviceable life is short and measuring accuracy is poor.In addition, because improper also will the causing of the installation of TC or using method 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 Measurement has also obtained certain utilization at the entrained flow bed gasification technology neighborhood.Such as the methane content that utilizes in the synthetic gas, calculate the gasification hearth temperature by relevant methane temperature corresponding relation model.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 by measuring sonde turnover cooling range, adopt the Indirect Temperature Measurements such as the indirect thermometric of heat transfer theory, CCD (Charge-coupled Device, charge coupled cell) image processing techniques thermometric and acoustic thermometry all owing to the reasons such as system is complicated, measuring accuracy is lower fail extensively to use in the actual industrial device.
Along with gasification with the decline of material quality, such as the ash fusion point of ash content higher in the coal for gasification and Geng Gao etc., adopt the airflow bed gasification furnace of water-cooling wall lining just progressively to find application.Because water-cooling wall lining Operational Temperature for Entrained Flow Gasifiers 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 the molten slag layer that is deposited on the measuring sensor will greatly affect the temperature measurement accuracy of measurement mechanism.The airflow bed gasification furnace of the water-cooling wall lining that has therefore now moved can only pass through gas composition, calculates the gasification hearth temperature according to the associated temperature model.But because the variation of gasified raw material quality and the impact of measurement precision of gas analyzer are calculated the temperature and the gasification hearth actual temperature that obtain and are differed larger.
As from the foregoing, under airflow bed gasification furnace high temperature and slag environment, existing measuring method also can't realize long period, online and Measurement accuracy gasification hearth temperature.Therefore need a kind of energy high temperature resistant, prevent slag deposition and measure accurately temperature measuring equipment and method and measure the gasification hearth temperature, realize the long-period stable operation of gas-flow bed gasifying apparatus.
