Description

A special feature of the proposed design is the location of windows, openings or nozzles supplying combustible DIMENSIONS and combustion air to heating spaces and removing combustion products.

In existing systems, the flame jets are either directed along vertical channels (flame wells) or horizontally, or the total flow of flame and smoke is alternately directed from one half of the heating space between the coke chambers to the other, so that, in addition to the vertical movement horizontal movement of the flame with additional separation of the horizontal flow into vertical jets or without it.

In the proposed construction, the heating spaces do not have vertical partitions or walls intended to distribute or direct the fiery streams. Each heating space in its lower part has a series of holes or windows for the entry of gas and air along its entire length, as well as below and throughout.

(S1)

length, -p of holes for outputting combustion products to a regenerator or recuperator; thus, the heating is carried out by means of flame streams distributed throughout the heating space, coming from the gas and air inlet ports, freely rising vertically and descending to their foot in outlet ports or openings. The mutual arrangement of these holes is shown in the attached drawings. FIG. Figures 1 and 2 show the arrangement of the holes in the case of a regenerative furnace with the location of the regenerators parallel to the axes of the coke oven chambers and perpendicular to the axis of the coke oven battery; A similar arrangement of holes will be in the case of a number of generators, running perpendicular to the axis of the chambers and parallel to the axis of the battery. Letters a and b denote holes and passages for gas and air that have passed through regenerators and are entering the fiery space; the letter b indicates holes through which the combustion products pass into the next pair of regenerators. The arrows indicate the direction of the flame. The number 7 is designated

a coke chamber, a 2-flame (heating) space.

On. f; 1g. rhspolpzheni.- holes in the case rekvaerati.zhy aschi; The alphabetic and numerical designations are the same as in the previous case: “- from the side for entering heated air in the fiery space of the heated air; bc late arrival of the heated raia; in-for recovery of combustion products into the heat exchanger.

Thus, the ascent and the descent of the flame jets and streams are performed freely, without vertical walls or partitions designed to distribute these streams and jets in the heating space. In order to impart rigidity and strength to the thin walls of the coke oven chambers, they can be connected by transverse walls, but these walls have no purpose to determine the direction of fire burnings and distribute heat over the heating space. Accordingly, these walls are made incomplete and not solid, but with interruptions; the arrangement of these walls is not consistent with the arrangement

airflow and exhaust holes, and is determined only by considerations of design comfort and convenience; . The whole of the irrigation between the two coke oven chambers can be either a single heating space, or it can be divided into a small number of separate heating spaces separated from each other by the joint venture. Each of these spaces is characterized by the above arrangement of the OTR and the movement of the flame flows.

The subject matter of the invention.

Combined cokes: a flax furnace of the regenerative and-sh recuperative type with continuous heating walls equipped with spacers for fittings; them, mechanical strength, different from ic., the largest holes for rising gas and air flows and the downward iiUiix of the combustion products flows are located at the entire heating pier at its base in the intermittent aor
