Abstract
The utility model discloses a biomass steam generator which is capable of preventing biomass fuels from being ignited in a feed pipe. The biomass steam generator comprises a body provided with a hearth, and the feed pipe and an air-incoming header pipe are arranged on the body. The biomass steam generator further comprises an air-inducing pipe, one end of the air-inducing pipe is used for being communicated with an air-supply source, and the other end of the same is communicated with the feed pipe.
Description
Technical field
The utility model belongs to the technical field of biomass boiler, specifically relates to a kind of biomass steam generator.
Background technology
At present, the biomass steam generator on market comprises body, feed pipe, blast pipe, the fire grate with burner hearth; Be provided with feed pipe and blast pipe on body, be provided with fire grate in burner hearth, blast pipe, feed pipe all are connected with burner hearth, the short transverse upper blast pipe of body be positioned at fire grate below, feed pipe be positioned at fire grate above.Send in burner hearth by biomass fuel and drop on fire grate by feed pipe, by blast pipe, oxygen being sent into from the position of fire grate below in burner hearth with combustion-supporting material burning.Adopt the steam generator of this structure, fuel is incomplete in the burner hearth internal combustion, causes waste of fuel; Moreover fuel relies on self gravitation to enter in burner hearth by feed pipe, its time through feed pipe is longer, because the temperature in burner hearth is higher, easily causes fuel just to be ignited in feed pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of biomass steam generator, and it can avoid biomass fuel to be ignited in feed pipe.
The purpose of this utility model is achieved in that a kind of biomass steam generator, comprise the body with burner hearth, be provided with feed pipe and air intake house steward on body, also comprise induced duct, an end of described induced duct is used for and air supply source is connected, the other end of induced duct is connected with feed pipe.
On the basis of such scheme and as the preferred version of such scheme: described air supply source is independent of the air pump for the induced duct air feed.
On the basis of such scheme and as the preferred version of such scheme: described air supply source is formed by the air intake house steward.
On the basis of such scheme and as the preferred version of such scheme: described feed pipe is positioned at described air intake house steward's top.
On the basis of such scheme and as the preferred version of such scheme: described feed pipe is positioned at described air intake house steward's top.
On the basis of such scheme and as the preferred version of such scheme: described induced duct is positioned at body.
The utility model outstanding and useful technique effect compared to existing technology is:
1, biomass steam generator of the present utility model has adopted the structure of induced duct, can by this induced duct, be introduced in feed pipe by gas, this gas enters in burner hearth by feed pipe again, during this period, this portion gas plays souring, make the biomass fuel fallen in feed pipe fall rapidly in burner hearth under the souring of gas, reduce the holdup time of biomass fuel in feed pipe, to avoid biological, in feed pipe, ignited, to reduce the loss of biomass fuel, further improved this biomass steam generator energy-conservation, the performance reduced discharging.
2, biomass steam generator of the present utility model has adopted an end of induced duct has been connected to the structure on the air intake house steward, forms the structure that this biomass steam generator can share an air pump, makes the more compact structure of this biomass steam generator.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1;
The biomass steam generator of the present embodiment, comprise the body 1 with burner hearth 11, is provided with feed pipe 2 and air intake house steward 3 on body, also comprises induced duct 4, and the two ends of described induced duct 4 are connected with air intake house steward 3, feed pipe 2 respectively.Structure due to this biomass steam generator employing induced duct, can make a part of gas be introduced in feed pipe by this induced duct, this portion gas enters in burner hearth by feed pipe again, during this period, this portion gas plays souring, make the biomass fuel fallen in feed pipe fall rapidly in burner hearth under the souring of gas, reduce the holdup time of biomass fuel in feed pipe, to avoid biological, in feed pipe, ignited, to reduce the loss of biomass fuel, further improved this biomass steam generator energy-conservation, the performance reduced discharging.
In the present embodiment, described induced duct 4 is positioned at body 1.Adopt this structure, can be that gas in induced duct carries out preheating by the heat on body, the cold air of avoiding being provided by air pump is directly sent in burner hearth and is reduced the temperature in burner hearth, make the heat provided after biomass fuel combustion more for making water form steam, further improve the heat utilization efficiency of this biomass steam generator, thereby reached the purpose of energy-saving and emission-reduction.
In the present embodiment, described feed pipe 2 is positioned at described air intake house steward's 3 top.
As the distortion of above-described embodiment, can adopt an independent air pump, by this induced duct 4 to feed pipe 2 air feed.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection domain of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection domain of the present utility model.
Claims (5)
