Description
Technical field
The present invention relates to a kind of boiler furnaces, belong to boiler plant technical field.
Background technique
Boiler is a kind of energy conversion, and the energy inputted to boiler has chemical energy, electric energy in fuel, boiler output
Steam, high-temperature water or organic heat carrier with certain thermal energy.The original meaning of pot refers to that the water container heated on fire, furnace refer to burning
The place of fuel, boiler include pot and furnace two large divisions.The hot water or steam generated in boiler can directly be industrial production and people
The people's livelihood is living to provide required thermal energy, mechanical energy can also be converted to by Steam Power Equipment, or again turn mechanical energy by generator
It is changed to electric energy.The boiler for providing hot water is known as hot-water boiler, is mainly used for living, also there is a small amount of application in industrial production.It generates
The boiler of steam is known as steam boiler, is often simply called boiler, is chiefly used in thermal power station, ship, locomotive and industrial and mining enterprises.It is either hot
Homogeneous solution-type reactor or steam boiler, basic structural unit are all to generate thermal energy by the fuel combustion in furnace to add the water in pot
Heat heating.Oven body part is usually provided with combustion chamber and connects the channel of combustion chamber, the high-temperature gas generated after fuel combustion
It being exported outward by channel, channel is often provided within pot body part and exchanges heat, make the flue gas cool-down being discharged by chimney,
The water in pot body part is set to heat up.However the channel in the prior art is often blocked by ashes, is not easily cleaned, and
The efficiency for influencing boiler also makes the water in pot body part exchange heat uneven.
Summary of the invention
Therefore, the purpose of the present invention is to overcome the defects in the prior art, provides a kind of channel and is not easy to plug, and pot
The higher boiler furnace of the thermal efficiency of furnace.
To achieve the goals above, a kind of boiler furnace of the invention, including shell, combustion chamber, dedusting chamber, blower, row
Smoke chamber and chimney are provided with water inlet and water outlet on the housing, hold water between the water inlet and water outlet
Chamber, the combustion chamber are located in the shell portion, and dedusting chamber is located at below the combustion chamber and by fire grate and the combustion chamber
Separate；If being evenly equipped with dry passage on the combustion chamber, the channel is vertically arranged and is connected to the combustion chamber and is located at combustion
The smoke extraction chamber above room is burnt, the chimney is located above the smoke extraction chamber；The air outlet of the blower be communicated with the first air duct with
Second air duct, first air duct are connected to the dedusting chamber；Venturi tube, the chimney connection are provided on second air duct
In the neck of the Venturi tube.
The first valve is provided on first air duct.
The second valve is provided on second air duct.
The water inlet is located at close to the position of the outer casing bottom, and the water outlet is located at close to the cover top portion
Position.
The water inlet and water outlet are distributed in the two sides of shell.
In cone setting, several channels are set on bevel edge and the vertex of the cone for the combustion chamber.
By adopting the above technical scheme, boiler furnace of the invention, since channel is vertically arranged, ashes are not easy in channel
Middle accumulation, avoids channel blockage；Combustion chamber is set on bevel edge and the vertex of the cone in conical and channel,
To make the more uniform of entire water containing chamber internal channel distribution, to increase heat exchange efficiency, also it is heated water more uniform；
Blower connects dedusting chamber by the first air duct, while Venturi tube is arranged on the second air duct, and chimney is made to be connected to the neck of Venturi tube
Portion, the effect of Venturi tube are that the interior wind-force in the second air duct is enable to form negative pressure in throat position, keep Boiler Furnace intracorporal
Flue gas quickly discharges.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
Below by way of the drawings and specific embodiments, the present invention is described in further detail.
As shown, the present embodiment provides a kind of boiler furnace, including shell 1, combustion chamber 2, dedusting chamber 3, blower 4, row
Smoke chamber 5 and chimney 6 are provided with water inlet 11 and water outlet 12, the water inlet 11 and water outlet 12 on the shell 1
Between be water containing chamber 13, the combustion chamber 2 is located inside the shell 1, and dedusting chamber 3 is located at below the combustion chamber 2 and passes through
Fire grate 8 and the combustion chamber 2 separate；If being evenly equipped with dry passage 7 on the combustion chamber 2, the channel 7 is vertically arranged and is connected to
The combustion chamber 2 and the smoke extraction chamber 5 above combustion chamber 2, the chimney 6 are located at 5 top of smoke extraction chamber；The blower
4 air outlet is communicated with the first air duct 41 and the second air duct 42, and first air duct 41 is connected to the dedusting chamber；Described second
Venturi tube 9 is provided on air duct 42, the chimney 6 is connected to the neck of the Venturi tube 9.
The first valve 43 is provided on first air duct 41.
The second valve 44 is provided on second air duct 42.
The water inlet 11 is located at close to the position of 1 bottom of shell, and the water outlet 12 is located at close to the shell 1
The position at top.
