Abstract
The utility model provides a reverse burning type normal pressure energy-saving boiler, and belongs to the field of heating equipment. The reverse burning type normal pressure energy-saving boiler is formed by a secondary air inlet furnace, a reverse burning furnace and a water tank, and is characterized in that a heat outlet of the secondary air inlet furnace is upward connected with a smoke inlet channel, the top end of the smoke inlet channel is shifted into the upper portion of a left cavity in parallel, the lower portion of the left cavity is anticlockwise connected with the left lower portion of an n-shaped cavity, the right lower portion of the n-shaped cavity is anticlockwise connected with the lower portion of a right cavity, and the upper portion of the right cavity stretches out of the boiler through a smoke outlet pipeline; the left cavity, the right cavity and the n-shaped cavity are combined to form an S-shaped cylindrical structure surrounding the smoke inlet channel, and a space formed by the smoke inlet channel, the left cavity, the right cavity, the outer surface of the n-shaped cavity and the inner surface of the shell body of the reverse burning furnace is upward communicated with the interior of the water tank. The reverse burning type normal pressure energy-saving boiler has the advantages that by adopting the secondary air inlet furnace, fuel can be burnt sufficiently, sufficient heat exchanging is carried out on heat in an inner smoke flue of the reverse burning furnace and the cavities, and then the heat is discharged from the furnace; the reverse burning type normal pressure energy-saving boiler is simple and reasonable in structure and better in heat conduction performance, effectively reduces the smoke exhaust temperature, has significant energy-saving effects, and saves energy by more than 30% compared with a traditional normal pressure boiler.
Description
Technical field
The utility model belongs to the heating equipment field, relates to a kind of atmospheric pressure energy-saving boiler.
Background technology
Boiler is a kind of heating equipment, consumes the side by side pollutant of amplification quantity of a large amount of primary energy, and the energy conversion efficiency that how to improve boiler is the emphasis problem that people study always.The unable application scenario of purchasing additional energy-saving equipment of the shortages of funding such as some grass-roots units, rural households exclusively engaging in a particular productionor trade particularly, prior art is carried out reducing energy consumption not dropping under a large amount of fund states, will bring obvious benefit to economic development and the energy-saving and emission-reduction work of society.
Summary of the invention
The purpose of this utility model is for the characteristics of existing normal-pressure boiler and not enough a kind of thermal efficiency of design reverse burning type energy-saving normal-pressure boiler higher, more energy-conserving and environment-protective.
The technical solution of the utility model is: the utility model by secondary air intake furnace, instead burn stove and water tank forms, it is characterized in that: the heat outlet of secondary air intake furnace upwards connects the anti-flue that burns the stove center, the parallel left cavity top that changes over to, flue top, left cavity bottom connects Π shape cavity lower left quarter counterclockwise, Π shape cavity right lower quadrant connects right cavity bottom counterclockwise, and the outlet flue pipeline is passed through outside boiler in right cavity top; Left cavity, right cavity, Π shape cavity are combined into a S shape tubular structure around flue, the outer surface of flue, left cavity, right cavity, Π shape cavity and the anti-joining water box inside that makes progress, space that the furnace shell inner surface forms of burning.
The beneficial effects of the utility model: the utility model adopts the secondary air burner hearth to make full combustion of fuel, then heat is discharged outside the body of heater through abundant heat exchange in the inner flue that instead burns stove and cavity again, simple and reasonable, heat conductivility is better, effectively reduce exhaust gas temperature, energy-saving effect is remarkable, more than energy-conservation 30 % of traditional normal-pressure boiler.
Description of drawings
Accompanying drawing 2 is the anti-stove partial interior structural representations that burn of the utility model.
The specific embodiment
As shown in Figure 1, the utility model by secondary air intake furnace 6, instead burn stove 1 and water tank 4 forms, wherein there are coal feed point 7 and slag notch 8 in the front of secondary air intake furnace 6, there are secondary wind inleting tube 9 and blower fan 10 in the side.The water tank 4 outer water level pipes 5 that are equipped with.More than identical with common normal-pressure boiler.
The heat outlet of secondary air intake furnace 6 upwards connects the anti-flue 11 that burns stove 1 center, as shown in Figure 2, parallel left cavity 12 tops that change over to, flue 11 tops, left cavity 12 bottoms connect Π shape cavity 13 lower left quarters counterclockwise, Π shape cavity 13 right lower quadrants connect right cavity 14 bottoms counterclockwise, and outlet flue pipeline 3 is passed through outside boiler in right cavity 14 tops.Left cavity 12, right cavity 14, Π shape cavity 13 are combined into one around the S shape tubular structure of flue 11, have greatly increased heat exchange area.
The outer surface of flue 11, left cavity 12, right cavity 14, Π shape cavity 13 and anti-joining water box 1 inside that makes progress, space that stove 1 shell inner surface forms of burning are so that water tank 1 interior rapid rising water temperature.Be equipped with two ash discharging holes 2 in anti-burning stove 1 cavity bottom and be connected to outside anti-burning stove 1 housing, but the cigarette ash in the periodic cleaning cavity is abundant to guarantee heat exchange.
Claims (2)
