Description

The proposed invention concerns a regenerative coke oven with individual regenerators located along the axis of the chambers with a heating wall divided into vertical firing passages.

In FIG. 1 shows a vertical longitudinal section of a furnace with a wall divided into four parts; FIG. 2 is a cross section of it; FIG. 3 and 4 parts of the furnace; FIG. 5-vertical longitudinal section of the furnace with a continuous circulation wall; FIG. b-cross section of it.

The coking oven on offer is heated by both poor and rich gas. In some types of existing coke ovens (Figs. 1 and 2), the heating wall of the furnace is divided in half by a blank wall 6. Both halves, each with their own regenerators, are independent heating systems, which makes it possible to regulate the work of the cold and hot sides. Each half of the wall, in turn, is divided in half by a vertical wall T connecting the quarters of such a furnace with a window and.

Four individual regenerators are placed under the furnace chamber, of which at each given moment two b-6i are under the ascending and two under-flowing current. During the operation of the furnace

I on the coke oven, the latter is fed i to the place of combustion with the help of one of the two I cornholes d, E, located one; over the other. Kornyur d supplies one quarter of the heated pier, the E-other cores. When working on the exalting current of quarters 1 and IV, the gas is supplied by the corners d and d- ,. For this moment, air is supplied through the bottom channel to the regenerators c5 and 6i and through the gas discharge enters the inlet g and j connecting the regenerator with two walls located on the sides of the coking chamber to which the regenerator belongs. The burning gas rises in quarters 1 and IV and, having crossed the window n, spreads through the walls 11 and II. Through window g and f, the flue gases enter the internal L-hi regenerators and leave through the hearth channels p in the hog.

Each half of the furnace must have its own hog, i.e. the furnace works for two hogs at once.

When working on a poor gas, the latter enters through one of the air regenerators (for example, L) with a rich gas. Air is fed through the regenerators. Then the process is similar to heating with coke oven gas.

Due to the low resistance of the furnace, the air is supplied by itself.

For free circulation of combustion products, a perpendicular vertical wall is located perpendicular to the axial axes of the coking chambers and is provided with a series of holes a formed by a cantilever brick b. The laying of this brick, alternating with the brick brick, creates a vertical wall with openings that is strong enough and at the same time facilitates the furnace and gives greater heat access to the chamber.

Thermally, such a circulation wall allows gases flowing from one place to another to equalize the temperature. Thus, an uneven gas supply from the nozzles cannot be significant, since each quarter represents, with sufficient strength, one continuous combustion chamber.

In other types of furnaces (Figs. 5 and 6), gas is fed into the furnace through the cornices d, one of which feeds even and the other odd burners. For heating the air and recovering heat from the exhaust flue gases, the furnace has four regenerators for every two heating walls. Two work for smoke, two for air. The regenerators extend along the whole furnace and work for two boars; for uniformity of supply, they are separated in the middle by a partition Z., each half being connected to its own hog. Regulators 2, 3, b, 7, 10, 11 (Fig. 5) operate on the air, and the rest on the smoke.

The air supply to the regenerators and the exit of flue gases are made through

hearth channels p in the hog. Through the gas discharge and regenerator, the gaseous products are communicated with the heating wall using the g, y ends. Each pair of regenerators (for example 2, 3, 4, 5, etc.) feed even or odd burners. Gaseous products are supplied to the floor of the pier through the air inlets e that enter the sides of the rich gas burner. Smoke is also discharged in the same way.

Due to the installation of spacer walls fitted with apertures a, the entire furnace wall acquires the structure of a common combustion chamber with ascending and descending ceilings from even or odd burners.

The ascending flow rises to the top of the furnace along the vertical of the burn. Parts of it that are losing heat are wrapped through holes and lowered along the smoke vertical. The operation of such a pier completely eliminates the unevenness of the heating, since, according to the hydraulic essence of the flame, it will always strive to equalize the temperature of the pier when it reaches all parts of it.

The subject matter of the invention.

A regenerative coke oven with individually regenerators located along the axis of the chambers with a heating wall divided into vertical firing passages, I characterized in that the spacer walls forming the vertical firing passages are provided with a number of holes and for free circulation of combustion products. to the author's testimony of V.
