Description

The proposed continuously operated coking oven, referred to as a coke oven type with a vertical chamber and external regenerators on the sides of the oven, is intended for the coking of peat.

The main difference in the characteristics of coking coal and peat lies in the fact that coal, during coking, slightly increases in volume, by the end of the coking process, fills the entire chamber, and peat coke decreases by almost half in its volume, due to which A conventional chamber kiln design would have been half wasted by the end of the coking process.

The heating walls in the proposed furnace are divided by a transverse vertical wall into two parts and each part has horizontally located fire channels, and in the lower part a horizontal channel for removal of distillation products, which thus pass through the thickness of hot peat.

In FIG. k depicts a vertical cross section of the furnace; FIG. 2 is a section along the SS in FIG. one; FIG. 3 is a section along the explosive in FIG. 1, and FIG. 4 - LLNA fig incision. 1. (19)

We offer a chamber, furnace, width C) 5 m and arbitrary other sizes, depending on the capacity (approximately m and m}, heated by the own rich or poor gas system of the flue channels 1, located as usual in the walls of chamber 2. The heating channels 1 are located horizontally for uniformity of heating and the ability to change the heating temperature of the peat according to the loading height if desired, depending on its humidity. The flue gases coming out of the heating channels enter the regenerators 3 taken out from under the furnaces sides to make room for the bottom unloading of peat coke, to which the conventional coke pusher is not applicable. Gases from the generator are then supplied to dry the peat, which is recommended to have no more than 15% moisture for coking in chamber furnaces. almost unbeatable, as the volume of coked peat decreases, to replenish it with a new quantity; at the same time, the resulting peat is not periodically loaded, but through the bunker system and unloading almost continuously, bypass without coke pusher. In view of the fact that the cracked resin, as experience has shown, tells the fortress to peat coke, the removal of gases and vapors of the resin is not only from above, but also from below, which forces the resin vapors to pass through the thickness of the coked peat into the channels 4 of the heating pier. Discharge bins 5 are either arranged under each chamber, or common to two chambers, as indicated in FIG. one.

The heating channel system allows for uniform heating of the walls to produce a reversion of the direction of the gases, so that in each half of the furnace they either go along the indicated shelves from top to bottom or bottom to top.

All chambers are assembled into batteries and the discharge devices operate mechanically from the drive shafts all at once or separately.

The subject of invention.

1. A continuously operating coke oven, consisting of a vertical chamber and an external regenerative system, characterized in that each part of the heating pier, divided by a transverse wall, is provided with horizontally arranged pair-mutual-serving fire channels.

2. In the furnace according to p. 1, use a horizontal channel 4 located in the lower part of the heating pier for removal of distillate products through the thickness of red-hot coke.
