Description

  The present invention relates to a combustion control device for a stoker-type waste incinerator, which comprehensively displays all information related to waste combustion from a waste input hopper to a primary combustion chamber, a secondary combustion chamber, and an exhaust gas outlet. The present invention relates to a combustion information monitoring and control device for a stoker-type waste incinerator that can use such information for judgment and control of a combustion state.

  In recent years, in stoker-type waste incinerators, NOx concentration in exhaust gas and generation of dioxins have been prevented to prevent environmental pollution, making it possible to improve heat recovery efficiency and downsize exhaust gas treatment facilities. Many so-called new generation combustion systems are employed.

  In this new generation type combustion system, particularly stable combustion control is required. Specifically, (1) stabilization of combustion heat, (2) stable combustion at a target air ratio, (3) dioxin and CO It is required to suppress the occurrence of NOx and to suppress the fluctuation of NOx.

  On the other hand, in order to realize the items (1) to (3) above, (a) waste supply heat amount control, (b) combustion center / cutoff point detection control, and (c) secondary combustion air real-time control. Such technology has been developed and put into practical use.

  4 and 5 show an example of a stoker-type waste incinerator that employs the new-generation combustion technology developed previously. In the stoker-type waste incinerator of FIG. 4, the combustion information in the furnace from the infrared camera 16, the exhaust gas oxygen concentration signal from the oxygen concentration sensor 20, the dust layer level of the dry stoker from the dust layer level sensor 15, etc. Input to the controller 21, (i) measurement of the furnace temperature distribution using the furnace combustion information from the infrared camera 16, determination of the combustion center I and the fuel cut point E, (b) oxygen Calculation of total combustion air supply amount that oxygen concentration is within the set range based on concentration signal, (c) Drying, combustion, allocation to post-combustion zone of total combustion air supply amount based on measured furnace temperature distribution, etc. To adjust the temperature distribution in the furnace to a preset temperature distribution, and (d) based on the signal from the dust layer level sensor 15, the dust layer level and combustion center I of the dry stoker are determined. As it will be within the constant range by controlling the waste feed to the waste conveying speed and the furnace, so that to achieve stable combustion of refuse.

  In FIG. 4, 1 is a furnace body, 2 is a waste supply port, 3 is an ash discharge port, 4 is a stalker, 5 is a stalker driving device, 5a is a control unit of the stalker driving device, 6 is a pusher, and 6a is a pusher control. , 7 is an air box, 8 is an air supply device, 9 is a hopper, 10 is an air flow rate adjustment device, 18 is a waste heat recovery device, 19 is an exhaust gas processing device, 22 is an image processing unit, and 23 is a zone / temperature distribution determination. , 24 is a total air amount calculation unit, 25 is a total air supply control unit, 26 is a distribution air calculation unit, 27 is an air conditioning device control unit, 28 is a combustion center control unit, 29 is a waste conveyance control unit, and 30 is a garbage It is a supply control unit.

Further, in the stoker-type waste incinerator of FIG. 5, the so-called reducing zone 14 is formed by extracting the combustion gas G ′ in the space 12 above the rear combustion section of the furnace body 1 and returning it to the upstream side of the secondary combustion chamber 13. At the same time, combustion air is divided and supplied to primary and secondary combustion air, and further, a supply waste amount signal detected by the dust level sensor 31a of the hopper 9 and the supply waste amount detection device 31, and an exhaust gas oxygen concentration signal, The fuel cut point position and combustion center position signals detected by the infrared camera 16 and the combustion center / fuel cut point position detection device 17 are input to the combustion control device 21, and primary combustion is performed based on the combustion center position and the fuel cut point position. thereby adjusting the air supply quantity or the stoker operating speed, to control the secondary combustion air supply amount based on the exhaust gas in the O ₂ concentration and the like in the base, so as to achieve complete combustion of the waste That.

  In FIG. 5, 32 is a secondary combustion air supply fan, 33 is a secondary combustion air control device, 34 is a primary combustion air supply fan, 35 is a primary combustion air control device, 36 is a recirculation gas fan, and 37 is It is a reflux gas control device.

Although not shown in FIGS. 4 and 5, in the refuse combustion control in the furnace, the waste surface temperature on the stoker, the gas flow rate in the furnace, the dioxin precursor concentration in the exhaust gas, the waste quality of the supplied waste Waste heat generation amount, steam generation amount and steam temperature (pressure) of waste heat boiler, CO concentration and O ₂ concentration in recirculation gas G ′, etc. are input to the combustion controller (or combustion control device) 21 as control elements. The basic combustion control is appropriately combined and used.

Thus, the combustion control in the steady state of the new generation stoker furnace as shown in FIG. 4 and FIG. 5 is generally a combination of the following single loop controls (a), (b) and (c). It is done by. (A) Supply waste heat amount / Supply waste heat amount control-(Correction by combustion center position / fuel cut point control)-(Correction by air ratio control)-Adjustment of waste supply pusher / stoker speed, (b) Boiler evaporation amount /・ Combustion heat quantity control-(Fuel cut point position control / Unburnt substance control)-Primary combustion air-(Dry air quantity, Combustion air quantity, Post combustion air quantity) adjustment-(Correction by air-fuel ratio control)-Garbage Supply pusher / stoker speed control and (c) O ₂ concentration measurement / Secondary combustion air supply amount real-time control-(Correction by CO concentration control etc.)-Adjustment of secondary combustion air amount.

  However, the control systems such as (a), (b) and (c) are controlled independently from each other in each single loop, and are controlled in the incinerator. The object is also measured independently for each single loop. For this reason, depending on the degree of control, there is a situation where the control in each single loop interferes with each other, and it is difficult to realize more stable combustion.

For example, in the control (b) based on the boiler evaporation amount, when the boiler evaporation amount becomes insufficient, the primary combustion air amount is increased in order to increase the combustion heat amount, and is supplied via the air-fuel ratio control. Increase dust and stalker speeds.
On the other hand, the control of (c) based on the O ₂ concentration in the exhaust gas reduces the secondary combustion air amount via the secondary combustion air amount real-time control when the O ₂ concentration increases, Conversely, when the O ₂ concentration decreases, the amount of secondary combustion air is increased.
Therefore, if the increase in the amount of primary combustion air required by the control loop (b) corresponds to the decrease in the amount of secondary combustion air required by the control loop (c), there is a problem with the total air ratio. However, if the control loop in (b) requires an increase in primary combustion air and the control loop in (c) requires an increase in secondary combustion air, the total air ratio is maintained at the set value. In this state, it becomes difficult to achieve stable combustion while maintaining the O ₂ concentration at the set value.
