SU23906A1 - Regenerative coke oven - Google Patents

Description

In existing devices, coke ovens with the use of vertical groups of heating odes, which are connected to each other sequentially at the top and bottom through connecting chambers in which combustion air is supplied directly to the chambers, it is not possible to significantly increase the normal flow of gas and air reaching dangerous for the preservation of masonry temperature.

In the proposed device, all the combustion air, to which only a part of the gas is mixed, is supplied only to the outermost groups, which makes it possible to impart coking to a greater supply of gas and air with greater thermal energy not exceeding the limiting temperature.

In FIG. 1 shows a longitudinal section through the support wall of a rich gas furnace; FIG. 2 is a vertical section taken along the line II - II in FIG. 3 is a vertical section along the line III - III.Hi of FIG. one; FIG. 4 is a longitudinal section through one of the support walls and gas regenerators of the lean gas furnace; FIC 5 longitudinal section through one of the supporting walls and air regenerators

ovens for lean gas; FIG. 6 shows a section along line VI - VI in FIG. four; FIG. 7 is a section along line VII - VII “and FIG. four; FIG. 8 is a longitudinal section through one of the support walls and along the air regenerators of the rich gas furnace.

The proposed rich gas furnace (Figs. 1, 2 and 3) consists of vertical heating channels 3, divided into an even number of groups, each of which is separated from the adjacent partition 1 and communicating with the adjacent right or left through connecting chambers 2 located at the top alternately and below alternately at the top or bottom of the chimney. Thus, the flow of burning gas follows a wavy or sinusoidal path, with an intense flow of moving gas passing through each group of chimneys and the direction of flow of this gas changes sequentially from one group to the neighboring group. In the considered recovery phase, the flow flows from left to right.

Combustion air heated in the regenerator 4 is distributed through channels 5 located at the base of the rising chimneys of the last group depending on the draft regulated valve. Fig. 1
