System.
It further, include the fortune formed by mathematical modeling inside the belt conveyer scale of coal feeder dynamic correction system
Logic is calculated, the data in the run coal bin static weighing metering system are belt conveyer scale of coal feeder dynamic correction system use.
A kind of boiler as-fired coal individual metering method, using system as described above, comprising the following steps:
(1) start run coal bin static weighing metering system and belt conveyer scale of coal feeder dynamic correction system, in coal bunker not into before coal
It puts, feeder runs one hour weighing belt furnace coal weight for accumulating feeder out automatically, and run coal bin is weighed in the same period
System also calculates the coal bunker furnace coal weight of this hour；Calculating logic by the two coal amounts carry out automatic comparison, calculate to
The instantaneous coal amount correction coefficient of coal machine, and the coefficient is multiplied with the former instantaneous coal amount of belt conveyer scale of coal feeder automatically, to correct feeder
The instantaneous coal amount of weighing belt eliminates belt conveyer scale of coal feeder weighting error；
(2) belt conveyer scale of coal feeder cumulant is stored in the historical data base of control system in real time, needs to calculate certain time period
When furnace coal weight, the historical data of the period starting point, the belt conveyer scale of coal feeder cumulant of terminal time need to be only recalled, with terminal
The amount of period subtracts the amount of starting time section；
(3) arithmetic logic is established in the accurate metering system in as-fired coal point storehouse, is introduced run coal bin and is weighed in real time, this is weighed
It carries out calculating one hour coal bunker furnace coal weight using to hour computing module；When coal bunker is not into coal, the every fortune of feeder
Row one hour, belt conveyer scale of coal feeder furnace coal weight out was accumulated automatically；By coal bunker furnace coal weight, the belt conveyer scale of coal feeder of same hour
The two amounts of furnace coal weight carry out automatic comparison, calculate the instantaneous coal amount correction coefficient of feeder, make in correction coefficient satisfaction

Ensure that belt conveyer scale of coal feeder as-fired coal accumulation numerical value is the furnace coal weight that point storehouse is precisely measured eventually.
In above-mentioned steps (1): feeder belt claims correction coefficient to be set as 1 when starting for the first time after control system power failure,
When the deviation of feeder furnace coal weight and coal bunker furnace coal weight is lower than ± 1% or when being greater than ± 20%, correction coefficient is not acted on
System.
In above-mentioned steps (3): not done when feeder accumulates the deviation of coal amount and coal bunker static state weighing apparatus weighing difference lower than ± 1%
Amendment is not corrected when the deviation of feeder accumulation coal amount and coal bunker static state weighing apparatus weighing difference is greater than ± 20%.
More specifically illustrated with reference to the accompanying drawings:
As shown in Figure 1, 2, establish belt conveyer scale of coal feeder dynamic correction system, the belt conveyer scale of coal feeder dynamic correction system be
The arithmetic logic established in DCS, coal machine weighing belt dynamic correction system principle are to correct feeder based on coal bunker coal amount data
Weighing belt.Under the premise of coal bunker is not into coal, feeder runs one hour " weighing belt as-fired coal for accumulating feeder out automatically
Amount ", coal bunker weighing system also calculates " the coal bunker furnace coal weight " of this hour in the same period.Calculating logic by the two
Coal amount carries out automatic comparison, calculates the instantaneous coal amount correction coefficient of feeder, automatically by the coefficient and former belt conveyer scale of coal feeder wink
When coal amount be multiplied, the target for playing the instantaneous coal amount of amendment belt conveyer scale of coal feeder, eliminating belt conveyer scale of coal feeder weighting error.Practical work
In work, to prevent system exception, feeder belt claims correction coefficient to be set as 1 when starting for the first time after control system power failure, when
When the deviation of feeder furnace coal weight and coal bunker furnace coal weight is lower than ± 1% or when being greater than ± 20%, correction coefficient, which does not act on, is
System.
The run coal bin static weighing metering system is acquired with the belt conveyer scale of coal feeder dynamic correction system collective effect
Belt conveyer scale of coal feeder weighing coefficient in period, this weighing coefficient directly acts on running belt conveyer scale of coal feeder, accurate to count
Measure belt balance weighing data.The run coal bin static weighing metering system and the belt conveyer scale of coal feeder dynamic correction system cooperate
Accumulative logical constitution boiler as-fired coal divides storehouse accurate metering system, the accurate metering system in as-fired coal point storehouse rely on it is revised to
Coal machine weighing belt cumulant, the course of work are as follows: belt conveyer scale of coal feeder cumulant is stored in the historical data base of control system in real time,
When needing to calculate the furnace coal weight of certain time period, it is tired need to only to recall the period starting point, the belt conveyer scale of coal feeder of terminal time
The historical data of accumulated amount subtracts the amount of starting time section with the amount of terminal time section.
The as-fired coal divides the accurate metering system in storehouse specific renovation technique are as follows: one, operation is established in unit control system
Logic introduces run coal bin and weighs in real time, this is weighed and calculate one hour coal bunker using to hour computing module and enter
Furnace coal amount.Two, when coal bunker is not into coal, belt conveyer scale of coal feeder as-fired coal out is accumulated in the every operation of feeder one hour automatically
Amount.By the coal bunker furnace coal weight of same hour, the two amounts of belt conveyer scale of coal feeder furnace coal weight carry out automatic comparison, calculate to
The instantaneous coal amount correction coefficient of coal machine meets use condition (when feeder accumulation coal amount and coal bunker static state weighing apparatus claim in the correction coefficient
The deviation of the method for double differences is not corrected when being lower than ± 1%, when the deviation that coal machine accumulates coal amount and coal bunker static state weighing apparatus weighing difference is greater than ± 20%
When do not correct) when, this correction coefficient directly acts on the instantaneous coal amount of belt conveyer scale of coal feeder, eliminates belt conveyer scale of coal feeder weighing and misses
Difference.Finally, belt conveyer scale of coal feeder as-fired coal accumulation numerical value is the furnace coal weight that point storehouse is precisely measured.
It takes or uses for reference prior art and can be realized in the part that do not addressed in aforesaid way.
Certainly, the above description is not a limitation of the present invention, and the present invention is also not limited to the example above, this technology neck
The variations, modifications, additions or substitutions that the technical staff in domain is made within the essential scope of the present invention also should belong to of the invention
Protection scope.
