Description

The proposed spark chamber is formed of conical, metal bands, nozzles supported on a ring in a combustion pipe, with pipe pockets strung on them, facing downward and forming zigzag smoke passages, lengthening the path for complete sparks to burn.

The drawing shows a vertical section of the spark plug.

Inside the tube Ai, which diverts the combustion products, a ring B is inserted, onto which conical nozzles E composed of metal strips are attached. On the nozzles, horizontally dished ring rings, i3, facing downward in concavity, are strung together in a shakhmatny order.

Combustion products escaping through the pipe, meeting a number of dish rings D on their way hit them and are reflected downwards; colliding with newly entering gases and forming vortices, gases pass between rings M upward along a zigzag path and upon further following they meet a second row of similar rings M, again form vortices, etc. Sparks with gases pass through a spark distributor through the grid with zigzag passages, extend their path in the pipe, and as a result burn out completely, and the rings M are located on the nozzles so that they do not reduce the living section of the pipe A.

The subject matter of the invention.

Spark trap, characterized by the use of 5 conical nozzles E, which are supported on a ring, in a flue gas discharge pipe A, made up of metal strips, on which are dish-shaped, turned downwards, L rings, forming a mesh with zigzag smoke paths in their combination.
