SU12736A1 - Steam boiler heated by hot gases generated during combustion in the sprayed form of iron pyrites - Google Patents

Description

The proposed vertical-boiler type boiler is placed in a single downstream chimney surrounded by a combustion chamber, the outer walls of which have channels for heating the air. Nozzles for supplying pyrite atomization, which serves as fuel, are installed in the overlap of the combustion chamber. The latter, in its lower part, is provided with a series of collecting hopper receptacles designed to evolve iron oxides during combustion.

In FIG. 1 shows a vertical section of the proposed boiler; FIG. 2-horizontal section of it; FIG. 3 is a vertical section through the overlap and the lower part of the combustion chamber; FIG. 4 is a horizontal section of the outer layer of the outer wall of the combustion chamber; FIG. 5 and 6 is a horizontal section of the inner layer of the outer wall of the combustion chamber.

Boiler A. is placed in a single downstream chimney, surrounded by combustion chamber B (Fig. 1), in the ceiling of which, for supplying pyrites and air, nozzles are located and: Guide funnels B

(Fig. o). To transfer hot gases into the chimney, the upper part of chamber B is equipped with a number of windows D (Fig.;) Connecting it to the chimney. At the bottom of Chamber B there is a series of collecting funnel receivers D designed to accumulate iron oxides released during combustion. In order to preheat the air, the latter is pre-passed through: channels E (Figs. 2 and 5) in the outer wall of combustion chamber B. In order to form internal circulation flows, the inner annular wall of combustion chamber B provides the Ken in the lower part of the row of windows C (Fig. 3) connecting the combustion chamber with the chimney.

The subject of the patent.

A steam boiler heated by hot gases formed during combustion in a sprayed gland} of the south pyrite, characterized by the fact that boiler 1 is of vertical water tube type, circumference 1 is annular combustion chamber B with nozzles located in the overlap of the chamber and directional funnels B for feeding pyrite and air and a series of windows G,

for transferring the hot gases from the combustion chamber to the only downstream passage of the boiler, what is the combustion chamber in its lower part is equipped with a number of prefabricated for evolving at. burning oxides

iron, funnel-shaped pipes D and a number of windows C, in the inner annular wall of the boiler to form notes of the natural circulation of gases within the combustion chamber and the chimney of the boiler.
