Title: Improvements in and relating to pyrometers
IPC: G01J5/60
Filed: 1937-01-13
Abstract: 472,146. Automatic control systems. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 13, 1937, No. 1081. Convention date, Jan. 14, 1936. [Class 38 (iv)] [Also in Group XL] Temperature.-In the measurement of high temperatures, the difference between the energy radiated by a highly heated body on two different wavelengths is utilized as a measure of the temperature. For use in connection with a furnace, the selected wavelengths on which measurements are made are such that there is little absorption of the radiation by smoke and dust. Automatic control of the temperature of the furnace may be effected by the pyrometer. In the apparatus shown, a tube 6 heated in a furnace 1 emits radiation which is focused on to a curved slit 9 and is then refracted by a prism 11 to produce a spectrum, the monochromatic images of the slit 9 being focused on a twopart diaphragm 13. Alternatively, filters may be used instead of a prism, to obtain two bands of radiation. Between the diaphragm 13 and a photo-electric cell 14 is a rotating shutter 15 having two pairs of arcuate slits 16, 17 arranged at different radial positions, these slits being so placed that each pair allows radiation of approximately only one wavelength to pass intermittently. The shutter 15 is driven by a synchronous motor and rotates so that each of the slits 16, 17 allows radiation to pass to the cell 14 during one half cycle of the A.C. supply. The diaphragm 13 has a fixed part 22 and a movable part 23, and when these are at the maximum distance apart, energy of both wavelengths passes unobstructed to the disc 15. The position of the part 23 is automatically controlled by a reversible motor 25, the field windings of which are supplied with A.C. under the control of valves 32, 33. These are normally biassed to cut off by batteries 34, 35. The photo-electric cell 14 is in circuit with a valve 38 which, when there is variation in the light falling on the cell, passes a varying current through a transformer 36. This occurs when unequal amounts of radiation on the two selected wave-lengths emitted by the heated body pass through the slits 16 and 17 respectively, and as a result the voltage induced in 36 causes either the valve 32 or the valve 33 to conduct, and to enable the motor 25 to rotate in one direction or the other until the quanta of energy on the two wavelengths received by the cell 14 are equalized by movement of the shutter member 23. This movement is a measure of the temperature of the heated body, and may be indicated by a pointer 42 moving over a calibrated scale 43 and geared to a shaft 27 through which the motor 25 controls the shutter. The circuit of the furnace heater 2 may be automatically opened, by means of a dog 46 associated with the pointer 42, and acting on a switch 45, when the temperature reaches a predetermined point.

Title: Improvements in or relating to thermal cracking of heavy hydrocarbon oils
IPC: C10B55/10
Filed: 1955-01-21
Abstract: <PICT:0792000/III/1> In a process for the thermal cracking of heavy hydrocarbon oils by introducing the oil into a dense fluidized bed of hot solid particles and withdrawing the product-vapours together with a small proportion of entrained particles through a cyclone or other gas/solids separator having a dipleg through which the separated particles are returned to the fluidized bed, and wherein particles are continuously withdrawn from the bed and reheated, the reheated particles being then returned to the reactor to maintain the temperature therein, these reheated particles are returned via the dipleg of the separator in order to prevent it becoming clogged with deposits of coke.  The apparatus shown essentially comprises a coking vessel 1, an external cyclone 9, with a dipleg 11, and a combustion vessel 18 of the dense fluidized bed type. Vessel 1 contains a dense bed of hot coke particles having a pseudo-liquid level 2.  Steam is introduced into the lower part of vessel 1 through lines 7.  The feed, e.g. a vacuum residuum, is introduced via manifold 5 into the bed at a plurality of points. The product-vapours pass up into cyclone 9 where they are separated from entrained coke particles and then withdrawn through pipe 10.  Coke particles are continuously transferred from the dense bed in vessel 1 through line 16 into vessel 18, where a dense fluidized bed is maintained by air admitted through line 21.  Partial combustion of the coke particles takes place in vessel 18 and maintains a temperature therein of about 1100-1500 DEG  F.  Reheated particles are withdrawn from vessel 18 via line 17. Some of these reheated particles are returned to vessel 1 through line 17b, but a substantial proportion is returned via line 17a and the dipleg 11 of cyclone 9, gas such as steam for conveying the particles being introduced through lines 22.  The reheated particles introduced through line 17a mix with the particles flowing down dipleg 11 from cyclone 9.  Valve 12 controlled by instrument 13 ensures that the particles from cyclone 9 create a static pressure sufficient to prevent the flow of gas from pipe 17a to cyclone 9.  It may be necessary to introduce aerating gas through lines 14 into dipleg 11 in order to maintain the flow of particles therein.  Excess coke is removed from the process through line 15, and also particles that have increased in size to the extent of being difficult to fluidize.  An apparatus is also described wherein the coking vessel has internal cyclones for separating entrained particles from the product-vapours, and wherein the particles withdrawn from the coking bed are reheated in a transfer line burner.  A gravitating combustion zone may also be employed.  It is also feasible to reheat the withdrawn particles by heat-exchange with hot flue gases.
