Abstract
An induced air control system is applied to a hearth and comprises a pressure detector, an induced draft fan, a front feed proportion integration differentiation (PID) controller, a pressure adjuster and a transmitter. The pressure adjuster is connected with a rotation speed regulation controller of the induced draft fan, two ends of the front feed PID controller are respectively connected with an air amount adjuster of a hearth air inlet and a comparer of the input end of the pressure adjuster, the pressure detector is arranged in the hearth, the pressure detector is connected with the transmitter, and negative pressure signals can be fed back to the comparer at the input end of the pressure adjuster through the transmitter. The induced air control system can carry out signal detection and negative pressure feedback on hearth negative pressure and can adjust air inlet amount through the pressure adjuster to achieve the purpose of stabilizing and controlling the hearth negative pressure to guarantee stable and efficient running of a boiler.
Description
Technical field
The utility model relates to a kind of air output control system, is applied on the heat supply gas fired-boiler.
Background technology
Intake in the heat supply gas fired-boiler directly affects efficiency of combustion, intake can reduce efficiency of combustion at least, easily produce the pernicious gases such as carbon monoxide, although the excessive efficiency of combustion that makes of intake has improved, but also can make the too much loss of heat energy (being taken away by air), so in the transformation process to the heat supply gas fired-boiler, need to improve the air output control system.
The utility model content
The purpose of this utility model is to overcome the problem of above-mentioned prior art, and the air output control that a kind of efficiency of combustion is high, heat-energy losses is few system is provided.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of air output control system, be applied on the burner hearth, comprise pressure detector, air-introduced machine, feedforward PID controller, pressure regulator and transmitter, described pressure regulator is connected with the rotational speed regulation controller of air-introduced machine, the two ends of described feedforward PID controller are connected with the blast regulator of burner hearth air inlet, the comparator of pressure regulator input respectively, described pressure detector is positioned at burner hearth, pressure detector is connected with transmitter, and negative pressure signal is fed back to the comparator of pressure regulator input by transmitter.
The comparator input negative pressure set-point of described pressure regulator input.
The target of air output control is to keep a rational combustion chamber draft.Air output control is take combustion chamber draft as feedback, and the blow rate required is regulated for the PID of feedforward, and combustion chamber draft can better maintain near the setting value, is conducive to the stable and high effective operation of boiler.
Air output control described in the utility model system, by combustion chamber draft being carried out after signal detection, the negative pressure feedback, by pressure regulator intake is regulated, so just can be reached the purpose of stable control combustion chamber draft, and then guarantee the operation of boiler stability and high efficiency.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the structure chart of air output control described in the utility model system.
The specific embodiment
As shown in Figure 1, the described air output control of the utility model embodiment system, be applied on the burner hearth, comprise the pressure detector (not shown), air-introduced machine, feedforward PID controller, pressure regulator and transmitter, described pressure regulator is connected with the rotational speed regulation controller (not shown) of air-introduced machine, the two ends of described feedforward PID controller respectively with the blast regulator (not shown) of burner hearth air inlet, the comparator of pressure regulator input connects, described pressure detector is positioned at burner hearth, pressure detector is connected with transmitter, and negative pressure signal is fed back to the comparator of pressure regulator input by transmitter.
The comparator input negative pressure set-point of described pressure regulator input.
The target of air output control is to keep a rational combustion chamber draft.Air output control is take combustion chamber draft as feedback, and the blow rate required is regulated for the PID of feedforward, and combustion chamber draft can better maintain near the setting value, is conducive to the stable and high effective operation of boiler.
Air output control described in the utility model system, by combustion chamber draft being carried out after signal detection, the negative pressure feedback, by pressure regulator intake is regulated, so just can be reached the purpose of stable control combustion chamber draft, and then guarantee the operation of boiler stability and high efficiency.
