(54) WATER HEATING # 1Y BOILER

I

The invention relates to a power system and can be used, in particular, in hot water boilers. :

Hot water boilers are known, comprising a housing with a combustion chamber, a circumferential water jacket, in the cavity of which smoke pipes 1 are located.

The disadvantage of these boilers is low reliability due to uneven distribution of heat load.

The closest technical solution to the invention is a hot-water boiler; it contained a furnace equipped with a water jacket with a water chamber built into its upper part, in the cavity of which smoke tubes were installed, communicated by their inlet sections with a L2j furnace.

The disadvantage of the known hot water boiler is low reliability due to the formation of sludge in the water chamber, the presence of which leads to a deterioration of heat transfer and overheating. the lower wall of the water chamber.

The purpose of the invention is to increase reliability.

The goal is achieved by the fact that in the water chamber below the smoke

The pipes additionally have a longitudinal partition, which forms a slit channel with the lower wall of the chamber, communicated with one of its ends from the side of the inlet sections of the fire tubes with the cavity of the chamber, and the opposite end with the water jacket.

; The drawing shows a water heater; 10 tel, longitudinal section.

The boiler contains a furnace 2 equipped with a water jacket, 1 with a water chamber 3 built into its upper part.

15, the cavities of the water chamber 3 are installed flush-angled. pipes 4, communicated by gases with their inlet sections 5 with furnace 2.

In the water chamber 3 below the smoke

20 pipes 4 a longitudinal partition 6 is installed, forming with the bottom wall 7 of the chamber 3 a slotted kansh 8, provided with its one end on the side of the entrance sections 5 of the pipes 4 with a hollow cavity

25 water Kama 3, and the opposite end - with a water shirt 1.

The boiler is equipped with a pipe 9 for cold water and a pipe 10 for discharging heated water. The furnace 2 is equipped with a rare 30.

The boiler works as follows.

In the furnace 2, the fuel is burned, and the resulting gases come to the fireplaces 4, where they transfer the heat from the surrounding water and are removed from the boiler.

The cold water flows through the pipe 9 and, heating, successively passes through the water jacket 1, the slot channel 8, from where it enters the water chamber 3 and is discharged from the boiler through the pipe 10.

The presence of a longitudinal partition, forming a slit canal with the lower wall of the water chamber, leads to an increase in the rate of water circulation along the lower wall of the chamber, which prevents the sludge from falling on this wall and ensures the intensification of heat exchange and increase the reliability of the boiler. Formula. the invention

The boiler containing, supplied with a water jacket, a fire chamber with

a water chamber built into its upper part, in the cavities of which smoke tubes are installed, communicated by their entrance sections with a firebox, which is characterized by the fact that

in order to increase reliability by reducing the accumulation of sludge, in the water chamber below the fire tubes until a longitudinal partition is installed, forming with its lower

0 by a wall a slot channel provided by one of its ends from the side of the entrance sections of the fire tubes with the cavity of the water chamber, and the opposite end with the water jacket.
