Abstract
The invention relates to the technical field of heating furnaces, in particular to a control device for fuel in a heating furnace. The control device for the fuel in the heating furnace comprises a first flow controller, a first control valve, a fuel object, a flow transmitter, a second flow controller, a second control valve, an air object and a second flow transmitter. The first flow controller is connected with the first control valve, the first control valve is connected with the fuel object, the fuel object is connected with the first flow transmitter, the second flow controller is connected with the second control valve, the second control valve is connected with the air object, and the air object is connected with the second flow transmitter. The control device for the fuel in the heating furnace is simple in structure, achieves the fixed set point control over the flow of the fuel, greatly overcomes the influence of fuel flow interference, and enables the flow of the fuel to be smooth.
Description
Technical field
The present invention relates to a kind of control device, relate in particular to a kind of heating furnace fuel control device.
Background technology
In prior art, in use, the variation that affects temperature in heating furnace is mainly the impact that is subject to fuel flow rate and air mass flow to heating furnace, so fuel flow rate and air do not form certain ratio, fuel easily exists waste, and temperature also can be unstable.
Summary of the invention
The technical problem to be solved in the present invention is: heating furnace in use, the variation that affects temperature in heating furnace is mainly the impact that is subject to fuel flow rate and air mass flow, so fuel flow rate and air do not form certain ratio, easily there is waste in fuel, temperature also can be unstable, and a kind of heating furnace fuel control device is provided.
In order to overcome the defect existing in background technology, the technical solution adopted for the present invention to solve the technical problems is: this heating furnace fuel control device comprises flow controller one, control valve one, fuel object, flow transmitter, flow controller two, control valve two, air object and flow transmitter two, described flow controller one connects control valve one, described control valve one link fuel object, described fuel object linking flow transmitter one, described flow controller two connects control valve two, described control valve two connects air object, described air object connection traffic transmitter two.
According to another embodiment of the invention, further comprise described flow transmitter one connection traffic transmitter two.
The invention has the beneficial effects as follows: this heating furnace fuel control device simple in structure, realized the definite value of fuel flow rate has been controlled, overcome widely the impact that fuel flow rate disturbs, make the more steady of fuel flow quantitative change.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
The specific embodiment
Fig. 1 is structural representation of the present invention, figure comprises flow controller one, control valve one, fuel object, flow transmitter, flow controller two, control valve two, air object and flow transmitter two, described flow controller one connects control valve one, described control valve one link fuel object, described fuel object linking flow transmitter one, described flow controller two connects control valve two, and described control valve two connects air object, described air object connection traffic transmitter two.Flow transmitter one connection traffic transmitter two.
By control valve one and two pairs of fuel of control valve and air, control, realized more accurate flow ratio, guaranteed that two material total amounts are substantially constant, also have this structure to carry load down more convenient, as long as change lentamente the set-point of fuel control valve one, just can reduce fuel flow rate, air mass flow also just reduces from motion tracking simultaneously, and keeps both ratios constant.
This heating furnace fuel control device simple in structure, has realized the definite value of fuel flow rate has been controlled, and has overcome widely the impact that fuel flow rate disturbs, and makes the more steady of fuel flow quantitative change.
