Description
Technical field
The present invention relates to technical field of petrochemical industry, more particularly, to a kind of the continuous of Ethylene Cracking Furnace Tubes temperature
Measurement apparatus.
Background technology
The cracking technique with diamond heating is needed in ethylene production, in tubular type heats production technology, pyrolysis furnace stove
Pipe plays a part of to heat raw material and reactor, is the key component of cracking technology, and the operation conditions of pyrolysis furnace directly affects ethene
Yield and quality.Because cracking furnace pipe subjects the effect of high temperature, corrosion and load for a long time, can be produced inside and outside the tube wall of cracking furnace pipe
Raw coking and surface oxidation, cause the decline of boiler tube mechanical performance, material phase transformation, wash away the situation such as thinned, or even cause boiler tube
Seepage and Cracking Failure.External presentation in this failure procedure is the temperature change of tube wall.
To ensure the normal operation of cracking furnace tube, prevent furnace wall from failing, it is necessary to which it is accurate in real time to be carried out to furnace tube temperature
Monitoring and control, to make judgement promptly and accurately to the operation conditions of boiler tube, the means of use are monitoring pyrolysis furnace stoves
Tube wall temperature judges fluid operating situation in boiler tube.
The method of measurement furnace wall temperature has two kinds at present.A kind of method is that thermal infrared imager is set in stove, and this method can
To carry out taking pictures for leak case and insulating efficiency, but the real-time monitoring of boiler tube external skin temperatures is cannot be used for, therefore only being capable of conduct
The reference data of tube wall temperature, and exist expensive, reliability is low, the maintenance of instrument can only be in the plant downtime period
Interior progress.Another method is the artificial observation outside stove, specifically man-hour manually hand-held infrared radiation thermometer, by the fire door of pyrolysis furnace by
Manually thermometric is positioned by pipe.Method is simple, but because in-furnace temperature is up to more than 800 °C, and worker will face unlimited stove during operation
Mouthful, influenceed by powerful thermal energy radiation in stove, worker is difficult in a short time disposably to survey the boiler tube in fire door
