Abstract

A heating boiler comprising an ash pan, a grate, a combustion chamber, a water jacket, a chimney, water channels, a loading door, a door for servicing the grate, an inlet and an outlet, characterized in that it contains outer, middle and inner water shirts narrowing upward, the inner one and the middle water jacket communicates with water channels, and the outer water jacket below communicates with the inner water jacket, while the inlet and outlet nozzles are connected respectively to the external and medium her water shirts.

Description

The utility model relates to the field of "small" heat energy, in particular to the designs of solid fuel boilers designed for heating residential premises and buildings.

Known heating boiler according to patent RU 2084770. The boiler contains a housing with thermal insulation, a furnace, turning into a convective gas duct, made in the form of a 3-way shaft. In the niches formed by the flue, a rectangular coil is installed, in the flue there are removable turbulators and grates, a leveling shield, a water-cooled radiator, and a loading door. The disadvantage of this boiler is that the heat exchange process in the furnace is inefficient due to the presence of one water jacket, and this reduces the efficiency of the boiler.

Also known is a hot-water steel welded boiler of the KS Geyser series (http://www.otopleniedoma.com/page10-2.html), which can be selected as a prototype. The boiler is made in the form of a rectangular pedestal with an internal firebox surrounded by a water jacket. In the lower part of the furnace there are grid-irons unified for the entire range. The furnace is separated from the convective part by a visor. The boiler contains an ash pan, grate, a firebox, a water jacket, a visor separating the firebox from the convection part, a convective gas duct, water channels, a loading firebox with a door, a door for servicing the grate.

The disadvantage of the boiler is the low heat dissipation of thermal energy concentrated in the furnace water jacket.

The proposed utility model is aimed at increasing the efficiency.

The technical problem was solved by placing three water jackets in the boiler design. Moreover, the inner and middle water shirts communicate with each other by water channels, and the outer water jacket from the bottom communicates with the inner water jacket. In this case, the inlet and outlet pipes (return and supply) are connected respectively to the outer and middle water jackets.

The device of the boiler is shown in the figure.

The boiler contains outer 1, middle 2 and inner 3 water shirts. The inner and middle water shirts communicate with each other by the water supply channels 4, and the outer water jacket from the bottom communicates with the inner water jacket. The inlet pipe 5 and the outlet pipe 6 are designed to supply hot water to the heating system. Through the chimney 7 produce exhaust gas into the atmosphere. The boiler is equipped with a loading door 8 for filling combustion products 9 into the combustion chamber 9 and a grate door 10 for cleaning the combustion chamber of residual combustion products. The combustion chamber is equipped with a grate 11. A sliding ash pan is installed under the grate 12. To clean the inside of the boiler from soot, doors 13 are provided on two levels.

The boiler operates as follows.

Through the door 10, firewood is loaded into the combustion chamber and fired up. Then the door is closed, and through loading door 8, coal is poured onto the firewood that burns. When burning fuel in the combustion chamber 9, the temperature and the heated gases increase, passing the maze between the water jackets 1, 2, 3, and the water channels 4 give their thermal energy to the water contained in them. Partially cooled gases through the chimney 7 are released into the atmosphere. Heated water rises convectively, and through the outlet pipe 6 enters the heating system. Partially cooled water in the heating system through the inlet 5 returns back to the outer water jacket 1 and the middle 2 and inner 3 water jackets associated with it. Thus, water is circulated in the heating system.
