Description

In the proposed steam boiler in order to increase the heating surface, the fire tube part is concentrically placed in an annular boiler.

In FIG. L depicts a longitudinal section of the proposed steam boiler, in which both parts of it are connected by circulating corpses; FIG. 2 is a front view and a cross-section of it; and FIG. 3 is a longitudinal section of the boiler in which both parts of it are connected by nozzles.

The proposed boiler consists of two cylindrical parts, one inside the other; The internal part A, representing a conventional boiler with a flame tube, is concentrically inserted into the boiler In a circular section, on the sides of which horizontal burning tubes are placed. Part A of the boiler rests on chairs b, b and connects to part B or circulation pipes c, c (fig. 2) or pipes d, c (fig. 3); for the direction of gases between parts A, vi. In the boiler there are horizontal vdzdvizhnye partition walls a, a, laid on the squares and easily

replaceable in case of burnout or wear. Both parts of the boiler completely (Fig. 1-2) or partially (Fig. 3) are surrounded by common brickwork to form bypass and heating chimneys. In part B there are two cleaning hatches, and for descaling part A, there are two plugs at the side and one hatch at the bottom.

Hot gases from the flame tube can be sent either 1) to the fire tubes, then to the upper part of the annular channel between parts A B of the boiler, then to the lower part of the annular channel, from where to the upper chimney and, finally, to the lower chimney and chimney or 2) first in the ring chimney, and then through the smoke-flue pipe, then below and in the main chimney, which will depend on the construction of the brickwork in the front and rear of the boiler.

The subject of the patent.

The steam boiler, characterized by the fact that the usual fire-tube part A (Fig. 1) of this boiler is concentric, using the chairs 6, b and the dividing walls a, a

A boiler B is inserted in an annular section, fitted on the sides with burning tubes, which parts A and B of the boiler are connected to each other by circulation pipes in, in or in pipes (Fig. 3) and are surrounded completely or partially by the lining for both boilers to the boiler of bypass and heating chimneys, through which hot gases from the flame tube are passed through in series with annular channels and burning tubes.
