SU42283A1 - Cast iron sectional hot water boiler for central heating - Google Patents

Description

The invention goes to cast-iron sectional water-heating boilers for central heating, which are installed to form a set of separate boiler-independent fireboxes, using sections that are combined in a series of communicating with each other and consisting of a tubular ribbed drain with a poured to its upper part. horizontal finned tube system.

In the proposed boiler, to change the living section of the passageway connecting the station with the upper horizontal pipes of the section, in order to adjust the speed of water in the latter, clean hatches of each section installed on the upper part of the drain are provided with valves on the inside.

In FIG. 1 shows a front view of a section of a cast-iron sectional boiler for central heating; FIG. 2 shows a vertical section through / - / in FIG. one; FIG. 3 is a horizontal section along I-II in FIG. one; FIG. 4-vertical cross-section of the boiler; FIG. 5 is the same longitudinal section of it;

(

FIG. 6 is a diagram of the inclusion of boiler sectional groups.

The cast iron water boiler is assembled from the cast iron sections on double cones, followed by flaring, combining the sections into sequentially communicating groups, //, III, IV (Fig. 6).

Each section consists of a tubular ribbed stool 5, 6 s. a system of horizontal finned tubes 3, 4, 7 poured to its upper part. For mechanically cleaning the pipes of the section from scale, there are cleaning holes / and 2 located in the upper part of the stand.

The upper 7 and middle 4 pipes (a three-pipe ribbed system, where only carbonate scale is deposited) after washing with acid do not require mechanical cleaning, and therefore it is provided for them to only flush the acid-loosened acid with a sump from the hatch.

The boiler is installed above a separate firelift A, independent of the boiler (Figs. 4, 5), forming above the latter a vault. The burner can be adapted to burn any kind of fuel.

To regulate the speed of water movement in horizontal pipes, the rotary cleaning hatch of each section is provided on the inside with a shutter 8, which, by turning the hatch 2, changes the living section a and b (Fig. 1) of the passageway connecting the stationary to 5, 6 s . pipes 3, 4, 7 sections.

The sections of the boiler are divided into groups at the deaf nipples installed in the lower pipes of the effluent (fng. 6). Water flows into the nozzle a of the group /, through the nozzle b comes out of it and flows through the nozzle into the group // sections and sequentially through the nozzles d, e, /, g and h passes through the pipes of the /// and IV sections. By changing the number of blind nipples, the number of groups is changed, and consequently, the number of sections in a group, and with one or another installation of dampers, the speed of water movement in sections.

Subject invention

A cast-iron sectional water-heating boiler for central heating, installed to form a roof over a separate boiler-independent firebox, using sections that are combined into sequentially communicating groups and consisting of a tubular ribbed stack with a poured to its top a system of horizontal ribbed pipes, characterized in that in order to regulate the speed of water in the upper horizontal pipes of individual sections, a rotary cleaning hatch 2 of each section is installed vernshne employed in its riser is provided on the inner side flap, varied by turning the guide flap open area of the flow channel, connecting the riser with the upper pipe section.
