SU61645A1 - Vertical furnace for thermal processing of combustible - Google Patents

Description

The proposed vertical furnace for thermal processing of combustible consists of paired chambers located on the same axis and regenerators located on two floors for the upper and lower heating.

A distinctive feature of this furnace is the location of the bypass channels connecting the regenerators with vertical heating channels between the dual chambers and in the heads of the furnaces.

FIG. 1 shows a section of the furnace in chambers (/ - / in FIG. 4); in fig. 2 shows a section through the heating pane (// - // in FIG. 4); in fig. 3 is a section along VI-VI in FIG. 2; in fig. 4 is a section along Yy in FIG. five; in fig. 5 is a section along X-X in FIG. four; pas figs. b - section along VIII-VIII in FIG. 2; in fig. 7 is a section along IX-IX in FIG. four; in fig. 8 is a section of /// - /// in FIG. four; in fig. 9 is a sectional view of FIG. 2; in fig. 10 shows a section according to FIG. four.

The fuel enters the charging opening 1, is lowered into the coking zone 2 and then passes to the zone 9. In this zone, doksovanie or ungassed fuel due to the input of the gas-vapor cooling mixture in the cooling zone 4,

Decomposition gases can be removed from the top of the chamber through a tap from the charging device or from the bottom through windows 5, collecting duct 6 and window 7. By laying windows 5, it is possible to change the level of gas exhaust. When operating the furnace on small fuel, it is possible to arrange the shoulders 10, which facilitate the suction of gases from the fuel layer.

The unit has eight regenerators located in two floors with four regenerators in each. The heating system consists of a series of verticals 15 that heat the furnace chambers.

Verticals are connected using oblique passages 16 with horizontal collecting and distributing channels 17, 18, 19 and 20.

At each moment, one pair of channels removes smoke into the regenerators, the other delivers gas and air.

The furnace is intended to be heated by a lean gas.

In the heads of the furnace chambers, as well as in the masonry massif between the chambers, there are large channels connecting the verticals with the regenerators. The large channels 22 and 23 connect the even-numbered collecting channels according to No. 61645-2 -

22-18 and 23-20. Large channels 22 and 23 lead to the regenerators 14 and 8, respectively, 22-14 and 23-8. The large channels 21 and 24 connect the odd collecting channels and lead to the odd regenerators, namely 17-21-11 and 19-23-9.

The regenerators have hearth channels 12, which are equipped with air-gas clalans similar to those used in coke ovens.

The described heating system works as follows.

Even channels and regenerators are designed for gas, odd ones are for air.

At the moment when combustion products are removed through the upper regenerators, air and gas are heated in the lower ones. Gas and air along oblique passages enter the vertical where the combustion takes place. Smoke rises.

Through the period of alignment, the flow of gases changes. Combustion control is conducted by throttling gates located in the gas flow path. Shiber 25, regulating the flow in the horizontal channels, are placed at the entrance to them-.

Feed adjustment to verticals is made by throttling with hooks 26j located at the mouth of the vertical.

If it is necessary to recalibrate the slanting passages on the bottom of the vertical, the mouth of the vertical is disassembled and recalibration is carried out with the help of shtangi and bananas.

The furnaces are grouped into blocks of six chambers each. Blocks can be connected to batteries. Chambers are doubled; two cameras are located on one axis. Heating furnaces - upper and lower. For all six chambers, a general system of regenerators arranged on one side of the block is arranged parallel to the axis of the chambers.

Subject invention

A vertical furnace for thermal processing of combustible, consisting of paired chambers located on the same axis, and regenerators located on two floors, for upper and lower heating, characterized in that the regenerators are connected to vertical heating channels by means of by-pass channels located between dual cameras and in the heads of the furnaces.
