Problems solved by technology

[0002] At present, coal-fired boilers are roughly divided into two types: vertical and horizontal. The boilers of these two structures have their own advantages and disadvantages. The main performance is that due to the limitation of the structure of the vertical boiler, the heat exchange area cannot be too large, so the thermal efficiency is low. , the degree of automation is low, but it occupies a small area; while the horizontal boiler has a large volume, a large area, a complex structure, a higher thermal efficiency than a vertical boiler, and a high cost

Embodiment 1

[0019] Embodiment one: if figure 1 with figure 2 As shown, a squatting boiler includes a chimney, a furnace body, a furnace, a coal feeding device, an ash removal device, and a power device for controlling coal feeding and ash removal. It is characterized in that the coal feeding device is located at the top of the furnace body, and the furnace The outer layer is the furnace shell 7, inside the shell is the insulation material 8, the middle is the furnace, the upper part of the furnace is the upper heat exchange chamber 11, the lower part is the combustion chamber 23, and the center of the upper heat exchange chamber 11 is hollow for smoke exhaust and coal supply. The common channel 27 is composed of an inverted U-shaped water jacket 9, a heat exchange tube water jacket 10 and a water pipe 38 connecting the two; the combustion chamber 23 is an outer water pipe 13 connected to the outside of the U-shaped water jacket 9, located in The inner water pipe 12 under the common chan...

Embodiment 2

[0021] Embodiment 2: The rest is the same as Embodiment 1. There is a turbulence barrier 26 at the top of the inner water pipe 12, which is used to increase the resistance of the flue gas, prolong the residence time of the hot flue gas, and increase the heat transfer effect. The middle part has a combustion-supporting Vents 24 are formed.

Embodiment 3

[0022] Embodiment 3: The rest is the same as Embodiment 1. The ash removal device is composed of fixed furnace teeth 34, movable furnace teeth 35, ash removal rocker lever 16, central axis tube 17, bracket 18, and ash removal transmission rod 16. .

Abstract

A low-height boiler is composed of chimney, main body, firebox consisting of upper heat exchanging chamber and lower combustion chamber, coal feeder, ash discharger and power unit for coal feeder andash discharger. Said upper heat exchanging chamber is composed of common channel for exhausting smoke and feeding coal, reverse U-shaped water jacket, heat exchanging tubes, and water outlet tube. Said combustion chamber consists of external and internal water tubes and horizontal water tube. Its advantages are less floor area, big heat exchange area and high thermal efficiency.

Description

technical field [0001] The invention relates to a coal-fired heating boiler, in particular to a squatting boiler integrating the advantages of a vertical boiler and a horizontal boiler. Background technique [0002] At present, coal-fired boilers are roughly divided into two types: vertical and horizontal. The boilers of these two structures have their own advantages and disadvantages. The main performance is that due to the limitation of the structure of the vertical boiler, the heat exchange area cannot be too large, so the thermal efficiency is low. , the degree of automation is low, but it occupies a small area; while the horizontal boiler has a large volume, a large area, a complex structure, a higher thermal efficiency than a vertical boiler, and a high cost. In actual use, people hope to have a boiler with a small footprint and high thermal efficiency. Contents of the invention [0003] The object of the present invention is to provide a vertical squatting boiler w...
