The invention relates to equipment for the destruction of gaseous waste thermal method.

A device for the catalytic afterburning gas emissions, containing the secondary combustion chamber with a catalyst coating on the walls, which consistently coaxially installed swirl and the source of infrared radiation having a catalyst coating (RU patent 2033574, CL F 23 D 14/18, 1995).

A disadvantage of this device is the low efficiency is.

This result is achieved by a device for the catalytic afterburning gas emissions, containing the secondary combustion chamber with a source of infrared radiation having a catalyst coating, according to the invention, the source of infrared radiation is made in the form of a pack of corrugated plates, combs which are not parallel to the axis of the housing and the ridges of adjacent plates have holes on one side of each plate for placement of the ridges of adjacent plates with the formation of intersecting channels. This allows to increase the efficiency of gas purification due to the intensification of the mixing gas emissions in the zone of contact with the catalyst.

In a preferred embodiment, the profile of the holes does not match the profile of the ridges.

This further improves the efficiency of gas purification due to additional intensify the agitation.

In Fig. 1 shows a diagram of the device of Fig. 2 shows the front view of the plate of Fig. 3 - section a-a of Fig. 2; Fig. 4 and 5 presents accommodation options ridges in the holes in the plates.

A device for the catalytic afterburning gas emissions contains the camera 1 is the ameres 1 and the flanges 3 of the adjacent plates 2 and have 4 holes on one side of each plate 2 for placement of the ridges 3 without holes of adjacent plates 2 with the formation of intersecting channels. Plate 2 is connected to the current source 5 and the current passing emit in the infrared range of the spectrum. The surface of the wafer 2 is covered with a layer of catalyst. Combs 3 can be placed in the holes 4 of the adjacent plates 2 with the formation of gaps 6 if you do not match their profiles.

When the device gas emissions are served in the camera 1, in which the flow is distributed through the channels formed by the plates 2, passes through it, mixing in the zone of intersection of the channels between the plates 2, or flows from one surface of the wafer 2 on the other in the areas of education gaps 6. Under the action of infrared radiation contained in the emission of pollution are activated and oxidized to harmless substances in contact with the catalyst. The output from the camera 1 gas emissions are not toxic impurities and removed from it in the atmosphere.

Thus, the proposed device allows to increase the efficiency of gas purification.

1. A device for the catalytic afterburning gas emissions, containing the secondary combustion chamber with a source of infrared radiation having a catalyst coating, wherein the source of infrared radiation in the form of package gofer the Oia with one side of each plate for placement of the ridges without holes of adjacent plates with the formation of intersecting channels.

2. The device under item 1, characterized in that the profile of the holes does not match the profile of the ridges.

FIELD: heat power engineering.

SUBSTANCE: method comprises supplying fuel to the burner with simultaneous supplying of the primary air, burning fuel in the mixture with the primary air in the flue pipe of the combustion chamber, supplying the secondary air to the flue pipe downstream, afterburning the unburned fuel in the furnace gases in the afterburning chamber, supplying air to the flow of the hot gases outflowing from the afterburning chamber, and discharging heated air to supply it to the consumer. The burning and afterburning processes are carried out in three stages. In the first stage, the mixture of fuel with the primary air is burnt out for the low excess of the primary air. In the second stage, the burning fuel-air mixture is distributed over the periphery of the flue pipe, is swirled, and mixed with a portion of the secondary air that is supplied to the flue pipe at least in two zones. The mixture with high air excess coefficient is intensively burnt out. In the third stage, the remaining portion of the secondary air is supplied to the flue pipe and, being cooled and enriched with oxygen, the flue gases are supplied to the afterburning chamber and unburned fuel in the flue gases is burnt out in the chamber. The air heater comprises burner (1) with fan of the primary air, combustion chamber with external casing (2) and flue pipe (3) provided with ports (4) and (5) for supplying the secondary air and arranged in outer housing (2) to define ring passage (6) between flue pipe (3) and outer housing (2), and afterburning chamber (7) for unburned fuel in the flue gases. Fan (9) for blowing the secondary air is connected with the space of outer housing (2) of the combustion chamber. Swirler (10) made of a hollow conical mixer is mounted in flue pipe (3) and separates it into the primary A and secondary B chambers. The primary flue chamber A is interposed between burner (1) and swirler (10). The second chamber B is interposed between swirler (10) and afterburning chamber (7). Openings (4) and (5) for supplying secondary air to flue pipe (3) are arranged in at lest two zones of the secondary flue chamber B first of which is closer to swirler (10) , and the second chamber with openings (5) is closer to afterburning chamber (7). Ring passage (6) between flue pipe (3) and outer housing (2) is closed from the side of afterburning chamber (7).

EFFECT: expanded functional capabilities and enhanced completeness of burning.
