SU516951A1 - Apparatus for determining the ignition temperature of solid carbonaceous materials - Google Patents

Description

Devices are known which allow the ignition temperature of coal mines of coke and other carbonaceous substances to be ignited, for which E is used as a reactor. with quartz tubes. The reactor, which is mounted in a vice quartz tube, is 5 exploiters and yen is tsezhen. There is no possibility to investigate the material of different granulometric sizes; ta.va. The air flow through the layer of the test substance is heated unevenly in the electric furnace (the air is warmed up more than the center of the reactor walls), which leads to a distortion of the parameter being determined

The disadvantages of the known device

There are also limitations of the grain size of the test material - a lack of regular dispersion. pod; -; air, to. peaif.rop.

In most it k8n; Thanks to the device nehazan11e nepeostatkhi eliminated thanks Tou ,. that the internal surface of the reactor is made stepwise, - l each step has its own nanometer, and a removable center is installed on the bottom, and a metal block is rationally located on the top

The arrangement of the device is re-: Yelon of the temperature of Bospla% ee; 1K5t tsertsyTLerocyst materials in the drawing.

In the metal reactor 1. whose inner surface is filled with a three-stage one with different diameters, a perforated Cyo 2 is inserted with a marked diameter of the holes. A metal block 3 with a radial is placed on the upper protrusion: on the positioning holes. The unit is equipped with a device 4 tslz reguli-nII Institute of speed-STI popach vozauha. From above, the reactor is closed by a lid 5, in which there are a fitting 6 and four holes for the rod 7 and three thermocouples 8. In the bottom of the reactor, there is a 9, 8, h roquets of combustors. The heater is placed in the electric oven 10.

The device works as follows: A bottom 2 is inserted into the reactor 1, the diameter of the holes of which depends on the grain size of the test material, then the metal block 3 is installed, the device 4 for adjusting it is placed on it. Lirovaki air flow rate into the reactor. After that, the reactor is tightly closed with a lid 5 and immersed in an electric furnace 10. Thermocouples 8 are installed to measure the temperature of the reactor wall. FtpHTpa of the charge and air passed through it. A system for air flow and air flow metering is connected.

or by turning the rod 7, with HELP)

A plate with fires is shifted overlapping in one or another of the holes in the block. The temperature rise is carried out with a certain using an autotransformer.
