SU9072A1 - Instrument for determining the magnitude of the velocity and the direction of the flow of gases in various places of the combustion devices - Google Patents

Description

The proposed device is a pn;} 11achots, 1l determined the magnitude of the velocity and direction of the flow of gases in various places l) nightly devices.

On the horizon of FIG. 1 shows the instrument; (| sh. 2-4 raerineas in three-endpoint endikrnyh .x planes of the model of the furnace; Fig. e-8- details of the device; Fig. 9- view of the diagram, built on the axis of the instrument readings.

The device consists of a model A of the firebox (in the case of a locomotive dinosaur), a large scale, and a H torch with a motor C (Fig. 1). with POMONI and i; oT (i |) s, the flow of air is created in the model and is approximately equal to the conditions that cvHiecTByiOT in the firebox under study (that is, skortt, etc.).

In one mode, one of the walls, nara.chlel, the gas flow serves them as a piece of glass 1. And a friend, a piercer and a steak, is composed of two sheets 4 and 7. Sheet 4 can be moved up ai 1I1; FROM 3 Cornus clothed with gap 5. iorlen / igkurna to par-pravlevlenpu lyazov 3: lnst 7 also shifts to the forces of bpsta 4 in napranlenin slot 5k; kestk s. (figure 2 - 4). Tube 12 is inserted at 8; a tube 12 is fitted at one end with a head 16. to give it axial NejreMenieHM or Roiwra axis. and on the other, the introduction of a nol pyutr Koitsu model - foroKOM 21. from races. a nano-base noriena with a frame 20 and tubes 22 (pipes “Leto O, () braIschennyh screw to n.vdtsad1; a: m and a. search 21 from him (F1 7). Frame 20 has an axis 19 for weather vane 18 (||) ng. 8). onabzheshyugo. for C01 mol1}: use it with the plane of the plane of frame 20, narik 24 as pointer to the body of the current air flow, together with pointer 15 installed on disk 25 | associated with the mufti 14. relocatable along the groove 13 pipes 12 (php. (iV To determine ri.e CKOJIOCTH values of air flow service; 1; at pipes 22. passed through the cavity of pipes 12 n by means of processes 23 (Fig. 5) , connected ML1 H1) H NOMOPP1 1N31GNOVYh tubes with MIK Yum-nometra (on the Cherton not shown).

Priesthood / Shstn 4 and 7 can be installed on any bridge between the model A cavity and the working tube of tube 12, while fl101-ep 18 takes on a yuzhepi. appropriate air flow to the hot spot; Using the head 16, the tube 12 to align the frame frame 20 with the plane of the weather vane, you can, by means of the pointer 15, moving along the slit of the disk 25, be determined in the same way as the flow. One can determine the wellness of the air current with a tube 22 and disk 21. A direction in which it is normal to the air 10 frame 20, i.e., K naIri “, K1H: H10 air flow, as; -) then i is required when) a.bote with the Pitot tube.

On the basis of the indications of the instrument is an acute flow diagram of air f. Toike, applied to the grid on the scale of the magnitude and direction of the current of air (i, b, c, fig. 9). With the help of such a diagram, it is possible to identify deaf points / fireboxes, as well as zones for vortex motions that are recognizable by the model of the rotation of the wind vane.

By means of a predisposed instrument, it was possible to pierce the experience of air through 1m air, for which the air-agent entering the model A would be aggravated. For definition in various: places of the flue space, the temperature of the puffing air is at the working end of the pipe 12 of the propellant. Electric jHUjWiMeTp with wires, TOIWS cavity cavities, tubes 12 and connections with galvaiometro). To cool it, it provides ribs with 1H or approx, ruzuyupluyu her in a shirt.

Subject n and those and that.

1. The device d, l determine the magnitude of the velocity and the direction of the gas flow in various places of the combustion devices, characterized by the application of the model .4 (fit. 1--4) of the trampling device being tested, spabed by fan B and motor C to play current

air, in which model one of the walls parallel to the main current 1azo11. The slag is inserted into a nazy 2 glass 1, and the other, the side wall, is composed of two sheets 4 n 7. The sheet 4 of which can move up and down in the slots 3 of the modular housing, and is provided with a slot 5, perpendicular) 111,1X slots, and sheet 7. I have; sleeve 8 connected with it with graduated disk 25 can be interleaved in slots 6 of sheet 4 in the direction of slit 5. into which tube 12 enters . 2-8), carrying pa inserted into its thin end, firstly, a disk 21 with a rasiolo / perpeidicular to its plane-frame 20. having an axis 19 for a weather vane 18, provided with 1, for alignment with its plane of the plane of the frame 20 ball 24 and as a pointer. secondly, two reversing openings to the site of disk 21 at its center 22 (Pitot tubes). and,. through the cavity of the tube 12 and bred by the process 23, which are connected with a micromanometer. The assignment of mp for Definition is the velocity of the air flow, the direction of which velocity is determined by P1kale1pa.uic.i; c 2n pointer 1M 15. by typing on the muff 14. By spawning along the groove. -13 tubes 12. onabi; wand head 16 for joint axial displacement of it, in order to fit the desired wall in the cavity of the model of its working end, and new comfort near the axis, in order to 20 according to the flow of gases in accordance with the position of the weather vane 18 caused by this note.

2) In the device I described in item 1, I) and the working tube of the 12 electromechanical pyrometer is connected to the galvanometer through the cavity of the indicated tube and connected to the galvanometer in order to determine the subject line of the leak in various places of the furnace. air, which in such a case is heated and injected into the model.
