Hot water boiler for

The utility model relates to a power system and can be used in heating boilers.

A heating boiler is known that contains a furnace and rotary chambers with a screen arranged along their perimeter from horizontal pipes connected in parallel to vertical collectors forming an open coil and a shielded convective shaft, and the shaft is shielded by a continuation of the camera screen. (UK Patent N1143652, CL F24H1 / 40.1969}.

The disadvantages of this boiler are low profitability, increased consumption of metal and lining materials, significant dimensions and weight.

The closest in technical essence to the utility model is a horizontal-water tube boiler containing a furnace and convection chambers with horizontal heating surfaces separated by a partition, and the furnace chamber is equipped with upper, lower, side and rear screens connected respectively to the upper, lower and left side collectors, while the ends of the tubes of the side screens are brought into the convection chamber, are muffled and serve as collectors for convective tubes, and gas fuel

the right side collector forms a rectangular frame with the upper, lower and left side collectors, while the side collectors, side screen tubes and convective tubes are interconnected in series. (RF patent No. 2057997, CL F24H1 / 40, 1996.).

The disadvantages of a horizontal water tube boiler are the need to increase the number of convective pipes and the complexity of manufacturing while reducing the size of the boiler in width, as well as insufficient screening of the front wall of the furnace.

The technical result of the utility model is to create a design of an economical reliable boiler with a reduced overall width and increased shielding of the front wall of the furnace.

The problem is solved by the vertical installation of convective pipes and the movement of the side headers to the center of the front wall of the furnace.

Distinctive features: - convection tubes are installed vertically behind the furnace and are connected to the pipes of the upper and lower furnace screens, elongated beyond the partition, which allows to obtain a sufficient surface of convection pipes with a decrease

boiler width, since a decrease in the number of convective pipes is compensated by an increase in their length, while the complexity of manufacturing the boiler is reduced;

side collectors are offset to the center of the front wall of the furnace and connected to the upper and lower collectors in their middle part; which allows to increase the shielding of the front wall of the furnace;

the front screen, side screens and rear screen of the furnace are formed of horizontal loop-shaped pipes, the ends of which are connected to the side manifolds, while increasing the screening of the front wall of the furnace does not increase the complexity of manufacturing.

In fig. 1, fig. 2, fig. 3 shows the design of a gas fuel boiler.

The boiler has a furnace 1 and a convection chamber 2 located at the rear of the furnace and separated from it by a partition 3 with a window. The left side manifold 4 and the right side manifold 5 are mounted vertically # to the front wall of the furnace 1 at a distance between each other sufficient to install the burner b and the manhole 7 and are hydraulically connected to the upper 8 and lower 9 collectors. Side collectors are connected to each other by loop-shaped horizontal pipes 10, forming the front 11, rear 12, left side 13 and right side 14 screens. Horizontal pipes of the upper 15 and lower 16 of the furnace screens are connected to the upper 8 and lower 9 collectors, the ends of the pipes 15 and 16 are led through the partition 3 into the convection chamber 2, where the vertical convective tubes 17 are connected to them. The boiler is closed by an insulated jacket 20.

The boiler operates as follows.

The fuel burns in the combustion chamber 1, part of the heat released is perceived by the screen surfaces. Flue gases through a window in the partition 3 enter the convection chamber 2, formed by the heating surfaces from the vertical pipes 17, where, due to convection, another part of the heat is transferred by the heating surfaces. Those # // & 7th

the carrier through the pipe 18 is fed into the left side collector 4, divided by a partition passes through the lower row of horizontal loop-shaped screen tubes 10 into the right side collector 5, where it turns up and through the upper row of loop-shaped screen tubes 10 returns to the upper part of the left collector 4 connected to the upper collector 8. The coolant passes to the left side of the upper collector 8, divided by a partition, passes successively pipes of the upper screen 15, convection pipes 17, pipes of the lower screen 16, It flows into the lower manifold 9, turns to the right and through pipes 16, 17, 15 enters the right side of the upper manifold 8 and is discharged from the boiler through the pipe 19. The heat carrier passes through the boiler in several strokes in several turns at the optimal speed.

As a result, the design of the boiler was obtained, having economy and reliability no worse than the prototype with an increased degree of shielding of the furnace due to the applied front screen 11 and the possibility of reducing the width of the boiler, thereby reducing the metal consumption and the complexity of manufacturing.
