Abstract
The utility model relates to the technical field of heating furnaces and particularly relates to a fuel control device in a heating furnace. The fuel control device in the heating furnace comprises a first flow controller, a first control valve, a fuel object, a first 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. According to the fuel control device in the heating furnace, the structure is simple, constant value control of fuel flow is achieved, and the defect of fuel flow interference is greatly overcome so that the fuel flow is stable.
Description
Technical field
The utility model relates to a kind of control device, relates in particular to a kind of heating furnace fuel control device.
Background technology
In the prior art, heating furnace in use affects that the variation of temperature mainly is the impact that is subjected to fuel flow rate and air mass flow in the heating furnace, so fuel flow rate and air do not consist of certain ratio, there is waste easily in fuel, and temperature also can be unstable.
Summary of the invention
The technical problems to be solved in the utility model is: heating furnace in use, the variation that affects temperature in the heating furnace mainly is the impact that is subjected to fuel flow rate and air mass flow, so fuel flow rate and air do not consist of certain ratio, there is waste easily in fuel, temperature also can be unstable, and a kind of heating furnace fuel control device is provided.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: this heating furnace fuel control device comprises flow controller one, control valve one, the 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 present utility model, further comprise described flow transmitter one connection traffic transmitter two.
The beneficial effects of the utility model are: this heating furnace fuel control device simple in structure, realized the definite value control to fuel flow rate, and overcome widely the impact that fuel flow rate disturbs, make the more steady of fuel flow quantitative change.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Fig. 1 is structural representation of the present utility model, comprise flow controller one, control valve one, fuel object, flow transmitter, flow controller two, control valve two, air object and flow transmitter two among the figure, 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.
Control by control valve one and two pairs of fuel of control valve and air, realized more accurate flow ratio, guaranteed that two material total amounts are substantially constant, it is more convenient to also have this structure to carry load down, 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 realized the definite value control to fuel flow rate, overcome widely the impact that fuel flow rate disturbs, and makes the more steady of fuel flow quantitative change.
