SU401872A1 - TUBULAR FURNACE - Google Patents

Description

one

This invention relates to petroleum and chemical engineering.

Tubular furnaces of space-flat nlamenn are known, comprising a body divided by vertical non-enclosures into separate chambers, each of which has a radiant two-sided illumination screen and flat torch nozzles located in a row under the screen.

A disadvantage of the known furnaces are their limited capacities.

In order to increase power and efficiency in the proposed furnace, in one of the chambers, flat-flame nozzles are located in a row above the screen, and the partitions have through windows.

The drawing shows the proposed furnace, the cross-section.

The furnace comprises a housing 1, divided by vertical non-enclosures 2 into separate chambers, each of which has a radiant shield 3 of two-sided illumination and nloskofakelnye nozzles 4 located in the row under the screens. In one of the chambers, for example in the middle one, the nozzles 4 are located in a row above the screen, and the partitions 2 have through windows 5. The furnace chambers have convective bundles of pipes 6 and gas ducts 7.

The oven works as follows.

4 nlam jets are laid on the walls 2 and the walls of the hull 1. The heated walls, the partitions 2 n the burning torches emit thermal energy on the screens 3, heating the product in them. Hot flue gases pass through windows 5, partitions 2 and wash convective bundles of pipes 6, giving them heat. Further, through the ducts 7, the flue gases are removed from the nets.

Controlling the mode of operation of the injectors, various processes can be carried out in separate streams of radioaptic screens 3.

Subject invention

The tubing has a space-extending flame, comprising a body divided by vertical partitions into separate chambers, each of which has a radiant two-sided illumination screen and nloskofakelnye nozzles located in a row under the screens, characterized in that in one of the chambers, nloskofakelny nozzles were diluted in a row above the screen and the partition walls have through windows.
