But, the following problem of discovered in recent years: if charcoal can be generated and be not required in the overlong time of carbon build-up area stay
The substance wanted., whereas if charcoal is too short in the time of carbon build-up area stay, then charcoal do not gasified (oxidation) adequately and
It is likely to result in gasification efficiency reduction.Therefore, it is intended that charcoal is discharged it after carbon build-up area stay reasonable time,
Accordingly, it is believed to be desirable to which the position (that is, the accumulation of charcoal is horizontal) of the upper surface of the build-up areas of the charcoal in gasification furnace 2 is maintained at mesh
Near target height.
Therefore, it is controlled in the gasification installation 1 of present embodiment, so that the stack layer of charcoal is (in the substance of accumulation
Most of layer occupied by charcoal.Hereinafter sometimes referred to simply as " carbon build-up layer ".) the height of upper surface be maintained at target piling height

Device T3, the 4th temperature sensor T4, the 5th temperature sensor T5 and the 6th temperature sensor T6.These temperature sensors T1,
T2 ... can also both be configured on the high direction of furnace with configuring at equal intervals with unequal interval.These temperature sensors T1, T2 ...
It is electrically connected with control device 9.
As shown in Fig. 3 (a), on the high direction of furnace of gasification furnace 2, the first temperature sensor T1 is set to target piling height
Top first distance L1 at position.First temperature sensor T1 of present embodiment is on the high direction of furnace of gasification furnace 2
It is configured near oxidant supply mouth 13.
On the high direction of furnace of gasification furnace 2, second temperature sensor T2 is set to the second of the top of target piling height
Position at distance L2, second distance L2 are shorter than first distance L1.

The comparable position of limit for height degree, if the limiting altitude is such as to be judged as the height of the upper surface of carbon build-up layer lower than the height
The height that then can not be sufficiently restored using charcoal.
6 distance L1, L2 ... occurrence additionally depend on the size of gasification furnace 2, but, it is considered that make it for example
Tens centimetres.First~the 6th temperature sensor T1, T2 ... it can detect and be provided at the height of the temperature sensor respectively
Temperature in gasification furnace 2.
Although not illustrating, but, the first~the 6th temperature sensor T1, T2 ... it is for example each provided with multiple.Respectively
Multiple temperature sensor T1, T2 ... each along the arranged circumferentially of gasification furnace 2.These multiple temperature circumferentially configured pass
The average value of the detected value of sensor be used as the first~the 6th temperature sensor T1, T2 ... respective detected value, in following explanation
For obtain carbon build-up layer upper surface height judgement in will be used.But, as temperature sensor T1, T2 ...
Respective detected value come using value be not limited to average value, such as can also by temperature sensor T1, T2 ... each middle position
Number etc. is used as detected value.
Herein, the principle that the height of the upper surface of carbon build-up layer is obtained to the test section of present embodiment is simply said
It is bright.
The case where the charcoal that the position corresponding with temperature sensor on the high direction of furnace of gasification furnace 2 is accumulated fills
Under, it should detect compared with the situation (especially with the corresponding situation in the partially combusted region of progress) not filled by charcoal
Much lower temperature.This is because: carrying out heat resolve product in the position more closer to the top than carbon build-up layer of gasification furnace 2
Part burning, reach such as 1000 DEG C or more, and in carbon build-up layer lower than the temperature temperature (for example, 700~1000
DEG C) under carry out the reduction reaction based on charcoal.The test section of present embodiment is conceived to the temperature on the high direction of furnace in the gasification furnace 2
The feature for spending distribution, obtains the general height of the upper surface of the stack layer of charcoal.
Specifically, detected value acquired by temperature sensor adjacent on the high direction of the furnace for calculating separately out gasification furnace 2
The difference of (absolute temperature) determines that the difference is the temperature sensor of threshold value or more.Thereby, it is possible to grasp: the upper surface of carbon build-up layer
Position on the high direction of furnace for the temperature difference for detecting threshold value or more between adjacent temperature sensor.For example, second
In the case that the difference of the detected value of the detected value and third temperature sensor T3 of temperature sensor T2 is threshold value or more, it can be determined that
Are as follows: the upper surface of carbon build-up layer is located at the position between second temperature sensor T2 and third temperature sensor T3.
There are the differences of its multipair detected value in adjacent temperature sensor on the high direction of furnace of gasification furnace 2 to be more than threshold value
Temperature sensor in the case where, determine the maximum temperature sensor of the difference of detected value to.That is, it is judged that are as follows: carbon build-up layer
Upper surface be located in temperature sensor adjacent on the high direction of furnace of gasification furnace 2, detected value difference be threshold value more than and most
Between big temperature sensor.
Used above-mentioned threshold value when height about the upper surface for obtaining carbon build-up layer, it may be considered that carbon build-up layer it is pre-
Phase temperature and the difference of desired temperature of gas blanket of top for being located at carbon build-up layer determine.Each desired temperature can for example pass through
Trial run or parsing of gasification furnace 2 etc. and obtain in advance.Threshold value can be from such as 100~600 DEG C, more preferably 200~300
DEG C range in select setting.
It should be noted that the furnace Gao Fangxiang in order to control the position of the upper surface of carbon build-up layer, in the upper surface of carbon build-up layer
On position deviate from the configuration range of the first temperature sensor T1 to the 6th temperature sensor T6 in the case where, at least also need
The upper surface for knowing carbon build-up layer is positioned at the position more closer to the top than the first temperature sensor T1 or to be located at than the 6th temperature
The lower position sensor T6.
Therefore, in present embodiment, without finding threshold value or more in adjacent temperature sensor on the high direction of furnace
It in the case where temperature difference, is investigated by referring to the temperature difference that the past obtains: detecting the temperature difference of threshold value or more before tight
Be between the first temperature sensor T1 and second temperature sensor T2 or the 5th temperature sensor T5 and the 6th temperature sensing
Between device T6.
That the temperature difference of threshold value or more is detected before tight is the first temperature sensor T1 and second temperature sensor T2
Between in the case where, presumption are as follows: the position on the high direction of furnace of the upper surface of carbon build-up layer will deviate from the first temperature biography
Before the configuration range of sensor T1 to the 6th temperature sensor T6, the upper surface of carbon build-up layer be in the first temperature sensor T1 with
Height between second temperature sensor T2.Therefore, it can grasp: on the high direction of furnace of the upper surface of current carbon build-up layer
Position is located at the position more closer to the top than the first temperature sensor T1.
On the other hand, the temperature difference of threshold value or more is detected before tight is the 5th temperature sensor T5 and the 6th temperature
In the case where between sensor T6, presumption are as follows: the position on the high direction of furnace of the upper surface of carbon build-up layer will deviate from the
Before the configuration range of one temperature sensor T1 to the 6th temperature sensor T6, the upper surface of carbon build-up layer is in the 5th temperature biography
Height between sensor T5 and the 6th temperature sensor T6.Therefore, can grasp: the furnace of the upper surface of current carbon build-up layer is high
Position on direction is located at the position than the 6th temperature sensor T6 more on the lower.
By as above being judged, the control device 9 of present embodiment be based on temperature sensor T1, T2 ... detected value,
Obtain the general height of the upper surface of the current carbon build-up layer in gasification furnace 2.
Next, referring especially to Fig. 4, in order to the height of the upper surface of carbon build-up layer is maintained target piling height
The control flow nearby implemented in gasification installation 1 is described in detail.Fig. 4 has been expressed as making the upper table of carbon build-up layer
The flow chart for the processing that the height in face is carried out close to state more appropriate by control device 9.
Firstly, control device 9 from first~the 6th temperature sensor T1, T2 ... the detected value (step of temperature is obtained respectively
S101)。
Then, control device 9 obtains gas using above-mentioned principle using the detected value of the temperature obtained in step S101
Change the general height of the upper surface of the current carbon build-up layer in furnace 2.Control device 9 obtains the upper surface of current carbon build-up layer
Height and target piling height difference Δ H degree (step S102).In the explanation, when poor Δ H is positive value, it is meant that charcoal
The height of the upper surface of stack layer is located above compared with target piling height, when poor Δ H is negative value, it is meant that carbon build-up
The height of the upper surface of layer is located below compared with target piling height.
Specifically, the position on the high direction of furnace for being judged as the upper surface of current carbon build-up layer is located at than the first temperature
In the case where spending the position closer to the top sensor T1, control device 9 judges are as follows: the height of the upper surface of current carbon build-up layer
Deviate upwards relative to target piling height be more than first distance L1 distance (Δ H > L1).
