Description

A known method of obtaining steam and hot water from a single boiler installation. The division of the boilers into parts by a hot-water wall (screen) is not new.

During operation of boiler plants, in some cases the need for steam and hot water varies.

The described construction of the boiler is made of tubular sections and it is foreseen that the separating hot-water wall can be connected to its steam or hot-water part by installing it on the connecting pipelines of the valves.

This switch increases or decreases the heat output of each of the parts of the boiler.

FIG. 1 shows a cross section of the upper part of the boiler; in fig. 2 is a longitudinal section.

The two-furnace boiler is assembled from sections combined into a steam package 1 and a water heating package 2, and consists of two parts separated by a hot-water wall (tubular screen) 5. Heated

The water from the hot-water wall can be directed to the hot-water or steam section of the boiler via switch valves 4 and 5, respectively, to generate steam or to heat the water of the water heating system.

The flue gases are directed to economizer 6, where feed water is heated.

Water is heated for hot water supply in the water jacket 7 of the steam trap 8.

When the valves 9, 4, 5 are open and the valve 10 is closed, installed on the pipeline supplying hot water to the heating system, the boiler works as a steam one.

With the valves 4, 9, 10 open and the valve 5 closed, the steam package / and the screen 3 generate steam, and the hot-water package 2 produces hot water.

When valves 4, 5 and 10 are open and valve 9 is closed, the boiler operates as a water heater.

When valves 9, 5 and 10 are open and valve 4 is closed, the steam package produces steam, and the screen and water-heating package 2 produce hot water.

For hot water, water flows through fitting 11.

It is envisaged that economizer 6 can be used either for heating water coming from a water heating system or for heating water coming from a water supply system for a hot water supply system.

When the water coming from the heating system is heated, it is open to tapan 12 installed in the heating return pipe and valve 13 installed on the pipe supplying water to the return header of the boiler.

When the water coming from the water supply through the pipe 14 is heated, the cells & 12 and 13 are closed, and the; 5/16 and Gapans are open.

A feature of the proposed boiler design is the connection of the middle water-heating wall (screen) to two separated boiler parts with installation on the connecting pipelines of valves, with the help of which it is possible to switch the heat carrier coming from the middle water-heating wall (screen) to one or another part of the boiler.

The specified switching, providing the possibility to increase or decrease the heat output of each of the parts of the boiler, increases the flexibility of its operation.

Subject invention

A boiler for heating water or producing steam from tubular sections connected by pipes to steam and hot-water packages, between which there is a water wall, differing in m, that in order to reduce or increase the heat output of each of the parts (steam or hot-water), by means of pipes, on which shut-off valves are installed, is connected to both one and the other part of the boiler.
