SU12499A1 - Steam boiler - Google Patents

Description

The proposed boiler is provided with a two-branch flame tube with a snake-bent smoke tube, which is plugged from the end, and the hot gases from the flame tube are directed to the chimney channels adjacent to the boiler body and through pipes located inside the boiler to the chimney.

In FIG. 1 shows a schematic side view of a steam boiler; FIG. 2 - front view; FIG. 3 is a section along the line AB of FIG. 1 and FIG. 4.- same, along the line VG of FIG. one.

Inside the steam boiler, there is a fire tube, which is shut off from the end (fig. 1-3), which is equipped with two branches, which are connected to the steam collectors of the boiler (fig. 3). In the central part of the branches are located the water heating pipes /, which are opened to the steam collector with their upper end, and the lower end enters the pipe p, obliquely located at the bottom of the branch and open at both ends into the water space of the boiler. In steam collectors, a series of snake-like curved flue pipes (Fig. 3 and 4) are placed around the flue pipe branches, which are connected to the upper part of the branch by one end and flue ducts adjacent to the body of the boiler, with the other end. The latter, using the knees (Fig. 2), are connected to the pipes (q. 3) located inside the boiler, which, in turn, using the knees to (Fig. 1), are connected to the chimney h. Inside the fire tube are placed boiling coils m, which are connected to the water space of the boiler using knees w (Fig. 2). During boiler operation, hot gases from the flame tube are directed to its branches, wherefrom the smoke tubes come into the flue ducts about, then the knees go to the tubes inside the boiler to finally go through the double knee to the flue pipe 3.

The subject of the patent.

A steam boiler characterized by the use of a flame tube l from the end (Fig. 1), equipped with two branches connected to the steam boiler (Figs. 1 and 3) with water heating pipes p and next to serpentine-shaped curved fire tubes (phyp 3 and 4 ) by what

the branches and pipes, the hot gases from the flame tube, equipped with boiling coils m, are directed to the chimney pipes, which are attached to the boiler body, channels O,

for their further direction through the knee d (Fig. 1 and 4) and located inside the boiler pipe d (Fig. 3) and the double knee to the chimney 3.
