SU15181A1 - Kolosnikova lattice - Google Patents

Description

The invention relates to grates composed of tubular cooled water or a nary of the grates. In the proposed grate, the grate bars are placed on the firebox in groups one above the other and together form a stepped grate.

In the schematic drawing of FIG. 1 depicts a longitudinal section of the furnace with the proposed grill; FIG. 2 is a cross-section of it.

The proposed grate (Fig. 1) is composed of several groups of tubular grates 1, placed in steps one above the other across the firebox. Separate groups of grates are connected to each other by couplings 3, and the outermost ones are pipes 5; tank 4, containing coolant, as a result of which coolant flows from tank 4 through pipe 5 successively through all grates, cooling them out, and then out through pipe 5, after

which it can be used for various purposes. Grate bars in separate groups can be bent at the ends of 8, with one or both ends being embedded in the walls of the firebox (fig 2); in the case of embedding only one end of the grate, as well as long distances between the walls of the firebox and heavy fuel, the grate is supported at the other end or between the embedment points of the beams 7 (Fig. 1).

The subject of the patent.

1. Kolosnikov lattice composed of tubular water-cooled or steam-cooled grate, characterized in that grate 1 (Fig. 1 and 2) are placed across the firebox in groups one above the other and together form a stepped grate.

2. Use in the lattice of the serial connection of the grate bars described in paragraph 1 for the successive passage of the cooling medium through all the grates.
