Portion, does not play the effect reducing emulsion zone temperature, reduces the temperature of upper furnace on the contrary, affects boiler output；3. returning charge
Pipe and burner hearth junction are in oxygen-depleted zone, and fuel causes partial combustion unfavorable because of anoxic, and bed surface local temperature is relatively low, and cold in a large number
Grey falls into, and the low situation of regional area humidity is more prominent.
Content of the invention
For solving the above problems, the utility model provides a kind of benefit wind knot being applied to biomass fluid bed refeed line
Structure, solves the problems, such as that the insufficient, dust flow of burning is poor.
A kind of benefit wind structure being applied to biomass fluid bed refeed line described in the utility model, including film-type water-cooling
Wall, burner hearth and refeed line, described fin panel casing is located on described burner hearth lateral wall, and described refeed line lower end passes through described membrane type
Water-cooling wall simultaneously tilts to be located on described burner hearth sidewall, and described refeed line is connected with described burner hearth, also includes secondary air channel and air intake
Pipe, described secondary air channel is located in described refeed line, and described blast pipe is located at described secondary air channel upper end through described refeed line, described
Blast pipe is connected with described secondary air channel.
By in addition adding a secondary air channel in refeed line, promoting air flow in refeed line, can effectively eliminate and return
Expects pipe and the anaerobic condition of burner hearth junction, make biomass fuel combustion abundant.
Improve further, in described secondary air channel, be provided with air controller, described air controller is located at below described blast pipe, just
In the wind speed adjusting secondary air channel air intake, to the suitable oxygen of refeed line supplement.
Improve further, described air controller includes spherical air conduit valve and two rotating bars, two described rotating bars are symmetrical
Positioned at described blast pipe both sides, described rotating bar passes through described refeed line and described secondary air channel to be fixedly connected on described spherical air channel
On valve lateral wall, in described spherical air conduit valve, be provided with air channel, described rotating bar rotates described spherical air conduit valve, make described air channel with
Described blast pipe connection or closure.
Rotating bar connects spherical air conduit valve, so that described spherical air conduit valve is closely connect with described blast pipe lower end in secondary air channel
Touch, rotary motion bar, the size changing air channel with blast pipe connected entrance is to adjust air output；Preferably, air channel is bending shape, wind
The air intake vent in road is identical with air intake pipe orifice diameter, and the air outlet in air channel is more bigger than its air intake vent diameter, and moving air is from blast pipe
Entered in secondary air channel by the air channel of spherical air conduit valve, and then the air outlet from secondary air channel lower end sends into refeed line；Work as rotating bar
When rotation spherical air conduit valve makes wind passage mouth and air intake pipe orifice be completely superposed, mend air quantity maximum, when rotating bar rotation spherical air conduit valve
Wind passage mouth is made to arrange out with air intake pipe orifice, blast pipe lower end closed, stop mending wind, control blast pipe cross sectional flow rate in 5-10m/s
Good.
Improve further, described secondary air channel is in horn-like, in upper end, oxygenating effect of divulging information is more preferable for its osculum.
The beneficial effects of the utility model are：Structure is simple, and benefit wind effect is good, and material burning fully, improves boiler
Operating efficiency.
