SU24384A1 - Corridor Charcoal Furnace - Google Patents

Description

The present invention relates to charcoal kilns consisting of corridors divided into chambers of drying, dry distillation and cooling with heaters placed in the first two chambers.

In FIG. 1 shows a vertical axial section of the furnace; FIG. 2- horizontal section; FIG. 3-cross-section as drying; FIG. 4- the same section through the chimney; FIG. 5 - the same section along the cooling chamber.

The furnace is two adjacent corridors 1, each being an independent furnace (Fig. 3).

The corridor is divided by hermetic lifting doors 2 into three working chambers of drying chamber 2, burning 4 and cooling 5, and into two 6.7 vestibules at each end of the furnace, also closed by hermetic doors 8.9.

Each corridor has two fireboxes: one 10 of them serve to heat the drying chamber 3, the second 11 mainly to heat the burning chamber 4 and partially the drying chamber 3, the beginning of which is connected to the end of the cooling chamber 5 by pipe 12. The beginning of the cooling chamber 5 is connected with a chimney 13 provided with a firebox 14. Wood distillation products are diverted to the condensation device by a pipe 15.

The kiln's operation is as follows: a train of trolleys loaded with firewood, installed in the corridor, moves at regular intervals from the drying chamber to the burning chamber.

Before each shift, a freshly loaded car is brought into the vestibule with the outer door 8 open and the inner 2 closed; its hitch is made with the last car of the train, after which the outer door closes. Then, all the inner doors 2 are raised, the train is pulled onto one car, going out into the cooling chamber recess 7. During the movement of the train, the outer doors 9 of the vestibule of the cooling chamber are closed. At the end of the shifting, the inner doors are closed, the outer doors 9 of the vestibule of the cooling chamber open and the car with coal rolls out onto the outer paths.

The gases coming from the furnace 11 of the burning chamber 4 burn in the combustion chamber 16 and are directed to the channels 17 outside the cast iron recuperators and, cooling, heat the latter.

Channel 18, laid down below the heat exchangers, cooled products of combustion are returned back to the coagulation chamber 16, from where, having warmed up a little, they are used to heat part of the heaters 19 of the drying chamber. Sufficiently cooled, they enter the drying chamber.

Another part of the heaters 20 of the drying chamber 3 is heated by gases from another furnace 10, these gases also after heating the heater enters the drying chamber.

Thus, the combustion products from both furnaces enter the drying chamber, while in the burning chamber they are isolated from

G930B.

Having mixed in the drying chamber with evaporated moisture, the flue gases go through a vertical pipe into the pipe 12, where they are still cooled and enter the cooling chamber. Here, when they meet with burnt charcoal, they gradually heat up, cool the coal and finally go to the chimney 13. Cooling the burned coal with moistened flue gases prevents freshly burned coal from escaping.

. The presence of sufficient dilution by means of a chimney at a high temperature of the outside air., As well as at the beginning of the operation of the furnace, is obtained by heating the gases in the chimney with a special furnace 14.

The subject matter of the invention.

A charcoal kiln, divided into chambers of drying, dry distillation and cooling, and equipped with heaters and cyxovi distillation chambers, which, in order to sequentially carry the flue gases through the dry distillation chambers, the drying chambers through the drying chamber itself and through the cooling chamber, the heaters of the dry distillation chamber are directly connected to the heaters of the drying chamber opened into this chamber, connected in turn by a gas pipeline: the cooling chamber.
