Abstract

The invention relates to a power system and can be used in boilers operating in heating and hot water supply systems. The purpose of the invention is to increase productivity by increasing the use of flue gas heat. The boiler contains placed in the housing (K) 1, framed by bricking, the firebox (T) 2, respectively, with the upper, front, rear, and side framing screens (E) of finned pipes 7, as well as intermediate screens (E) with their own fins . In K 1, at least one additional T 2 with its E is installed in series with the formation of lifting ducts 14 with exit windows 15. The adjacent fins of all intermediate E are located on the middle part of the length of pipes 7 with the formation of upper and lower flow windows 17 and 18. Pipes 7 and 10, respectively, side and intermediate E and with fins and plates form the lowering ducts 21. When burning fuel in T 2, flue gases rise to the upper E, washing the front, rear and side E, then through the upper flow windows 17 come in flues-final year 21, whence through the lower window downcomers 18 extend in the lifting flues 14 and further through the output window 15 are removed in a chimney. 1 hp f-ly, 3 ill.

The invention relates to heat energy and can be used in boilers operating in heating and hot water supply systems.

The purpose of the invention is to increase productivity by increasing the use of flue gas heat.

FIG. I depicts a boiler, general view from the front without frontal lining; in fig. 2 shows section A-A in FIG. one; in fig. 3 - node I nd figure 2

The water-heating boiler contains the measured in the housing 1, the reverse-facing lining, the firebox 2, respectively, with the upper one, the rear end of the rear h (Zokovyy framing screens 3-6 of the pipes 7 with fins 8: 8, and such established between the side frames intermediate shields 9, pipes 10 of which are made with shchagnika 1 I, offset relative to the axes of the pipes 10, and arranged offset relative to the pipes 7 of the respective side screens 6, and case 1 is installed in a row at least one more on dopopititel on analogous firebox 2 with CBOHNCI corresponding to the top, persdn) m, followed by lateral framed; kp11im51 and interim gochpch tranaml 3-6.9, ustayipennp with 3a: iopoK 12 vi i 3 MC.iviy after No. 1 and co.jTueTCTBt HHo body 1 and c.icenim intermediate screen 9 main furnace 2 for.

Each pipe 7 of the side screens 6 is equipped with plastico 19, equipped with a gap of 20 relative to the fin 8 of its pipe 7, and the fins of the pipes 10 of the intermediate screens 9 are inserted with a free end into the gap 20.

The pipes 7 of the side screens 6 are connected to the lower longitudinal collectors 25 and through the pipes 7 of the upper screen 3 are connected to a longitudinal collector 26 of the upper screen 3, in which the partition 24 is also installed.

The pipes 7 of the front screen 4 are connected to the lower transverse headers 27 and to the lower longitudinal headers 25 and through the upper transverse headers 28 are connected to the upper longitudinal headers 26.

Tubes 7 of the rear screen 5 are connected to the lower cross-section. the collectors 29 connected to the lower longitudinal collectors 25 of the side screens 6. In its upper part of the pipe 7 of the rear screen 5 are connected to the upper transverse collectors 30 embedded in the upper longitudinal collector 26.

The longitudinal collectors 23 are connected to the feed water inlet pipe 31 and are connected to the upper longitudinal collector 26 pipes 1 32 and are installed with their starting point of the highest point of the upper collector 26

Feed water is supplied through nozzles 3) The upper longitudinal collectors 23 of the intermediate screens 9 meet partitions 24 on their way and descend through half the pipes 10, receive heat from the exhaust gases through the walls, from the lower longitudinal collectors 22, from where it rises through the second half pipes 10, also perceived the heat of flue gases, P the upper longitudinal collectors 23 and further through pipes 32 enters the longitudinal collector 26 of the upper screen 3, where, having met the partition 24, it is lowered along the rear screen 5 of the boiler to the lower longitudinal collectors 2 5 side screens 6, from where through the pipes 7 side

the screens 6 and the front screen 4 rises into the longitudinal collector 26 of the upper screen 3 and exits the boiler.

The proposed boiler allows to increase the heat removal from the heat exchange surfaces of the boiler and evenly distribute the thermal energy of radiation, convection between the heating surfaces of the side 6 and intermediate 9 screens of the boiler, increase its maintainability and, despite increased heat production, the boiler works on natural

At 15 a screen of the main furnace, gas, liquid and solid fuel can be compressed at the furnace created by the chimney, which indicates reliability of the boiler operation
