Abstract

A VERTICAL WATER BUBBLE WELLING BOILER containing a tube bundle connected to drums, the upper of which has a vertical partition and feedwater supply pipe, and adjacent to the drums are ethical gas-tight partitions installed between the tubes of the beam with the formation of successively connected along the course of the gases different gas-tight partitions installed between the tubes of the beam with the formation of successively connected along the course of the gases differing gas-tight partitions installed between the tubes of the beam with the formation of successively connected along the course of the gases differing gas-tight partitions installed between the tubes of the beam with the formation of successively connected along the course of the gases differ in increasing economically, that, the upper drum has two non-communicating water compartments, separated by a vertical partition, and to one and compartments connected only those tube bundle to .i torye arranged in the latter along the gas channel and the feed water inlet pipe connected to this compartment. 0 od o |

Description

This invention relates to heat engineering and can be used in industrial boilers. The aim of the invention is to improve the economy. FIG. I depicts a boiler, longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section b-B in FIG. one; in fig. 4 shows a section B-B in FIG. 3. The vertical water-tube two-boilers boiler contains a tube bundle 1 connected to the upper and lower drums 2 and 3, and screens 4-7, forming a furnace 8 equipped with a burner 9. Between the tubes of the beam 1 are installed adjacent to the drums 2 and 3 vertical gas-tight partitions 10 and I. Partitions 10 and 11 are installed with the formation of channels 1214 that are connected in series along the gas paths. The upper drum 2 is provided with a pipe 15 for removal of steam and a feedwater supply pipe 16 and has two compartments 17 and 18 that are not communicating in water and are separated by a vertical partition 19. The compartment 18 is connected

YES.

Yu 04 is only beam I pipes, which are located in the last channel 14 along the gas paths and the feed water supply pipe 16 is connected to this compartment. The boiler works as follows. The feed water through pipe 16 is supplied to the compartment 18 of the upper drum 2 and then through the pipes of the beam 1, located in the last channel along the gas channel 14, flows into the lower drum 3, heat up and cool it. given flue gases leaving the boiler to a temperature lower than the saturation temperature. From the lower drum 3, the feed water along with the boiler - circulating water through the pipes of shields 4–7 and the beam pipes i located in channels 12 and 13, due to natural circulation in the form of steam-water mixture enters the compartment 17 of the upper drum 2. The steam separates from the water and flows out of the drum 2 through the nozzle 15, and the boiler water through part of the beam pipes connected to the compartment 17 flows into the lower drum 3.
