Embodiment 1

[0028] Embodiment 1: as figure 1 As shown, a steam boiler includes an outer wall 1 and an inner wall 2, the outer wall 1 and the inner wall 2 are closed to form a water storage chamber 3, the top of the water storage chamber 3 is a steam chamber 3.1, and the inside of the inner wall 2 From bottom to top, there are slag discharge chamber 4, combustion chamber 6, air chamber 8 and high temperature chamber 16; the air chamber 8 communicates with the upper air inlet 7, the slag discharge chamber 4 communicates with the lower air inlet 5, and the combustion chamber 6 is provided with a plurality of ventilation pipes 13 communicating with the air cavity 8, and a plurality of air nozzles 13.1 are arranged on the side wall of the ventilation pipe 13; the ventilation pipes 13 and the air nozzles 13.1 supply oxygen to the flame, so that The flammable gas is fully combusted.

[0029] A plurality of fire tubes 9 are evenly arranged in the water storage chamber 3, the bottom of the fire t...

Embodiment 2

[0033] Embodiment 2: as figure 1 As shown, a steam boiler includes an outer wall 1 and an inner wall 2, the outer wall 1 and the inner wall 2 are closed to form a water storage chamber 3, the top of the water storage chamber 3 is a steam chamber 3.1, and the inside of the inner wall 2 From bottom to top, there are slag discharge chamber 4, combustion chamber 6, air chamber 8 and high temperature chamber 16; the air chamber 8 communicates with the upper air inlet 7, the slag discharge chamber 4 communicates with the lower air inlet 5, and the combustion chamber 6 is provided with a plurality of ventilation pipes 13 communicating with the air chamber 8, and a plurality of air nozzles 13.1 are arranged on the side wall of the ventilation pipe 13; a plurality of fire pipes are uniformly arranged in the water storage chamber 3 9. The bottom of the fire pipe 9 communicates with the combustion chamber 6, the top of the fire pipe 9 communicates with the top of the high-temperature cha...

Embodiment 3

[0037] Embodiment 3: The difference between this embodiment and Embodiment 2 is that a steam chamber 18 is arranged on the top of the boiler in this embodiment, and the inner chamber cross-sectional area of ​​the steam chamber 18 is smaller than the inner chamber cross-sectional area of ​​the outer wall 1 of the boiler. Moreover, the upper end of the steam pipe 12 leads into the top of the steam chamber 18 . A safety valve can also be set at the steam chamber to further improve the safety factor of the boiler.

[0038] By adopting the above-mentioned technical scheme disclosed by the present invention, the following beneficial effects are obtained:

[0039] 1) The present invention arranges a plurality of fire tubes 9 between the outer wall 1 and the inner wall 2 of the boiler. After scaling on the outside of the fire tubes 9, the fire tubes 9 expand when heated, and the scale will automatically fall off, thereby effectively avoiding the generation of burst tubes .

Abstract

The invention discloses a boiler which comprises an outer wall and an inner wall. The outer wall and the inner wall are sealed to form a water storage cavity; a steam chamber is arranged at the top of the water storage cavity; a slagging cavity, a combustion chamber, an air cavity and a high-temperature cavity are sequentially arranged in the inner wall from bottom up; the air cavity communicates with an upper air inlet; the slagging cavity communicates with a lower air inlet; a plurality of ventilating ducts communicating with the air cavity are arranged in the combustion chamber; a plurality of air spouts are formed in the side walls of the ventilating ducts; a plurality of fire tubes are uniformly arranged in the water storage cavity; the bottoms of the fire tubes communicate with the combustion chamber; the tops of the fire tubes communicate with the top of the high-temperature cavity; the bottom of a smoke pipe penetrates through the outer wall and the inner wall, and the smoke pipe discharges smoke out of the boiler. The boiler effectively avoids pipe explosion and is high in energy utilization ratio.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a vertical boiler with a new structure and high energy-saving efficiency. Background technique [0002] The current boilers have the following problems: Water pipes are generally installed in the boiler. Due to the water quality, the water pipes are prone to scaling. The rate is lower. Contents of the invention [0003] The object of the present invention is to provide a steam boiler so as to solve the aforementioned problems in the prior art. [0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows: a steam boiler includes an outer wall and an inner wall, the outer wall and the inner wall are closed to form a water storage chamber, and the top of the water storage chamber is a steam chamber, [0005] The interior of the inner wall consists of a slag discharge chamber, a combustion chamber, an air chamber and a high ...
