Description
Technical field
The utility model relates to industrial furnace, particularly a kind of pulse heat-accumulating industrial furnace.
Background technology
In the industrial furnace system, when fuel gas with low heat value such as adopting blast furnace gas is fuel or in order to improve utilization efficiency of energy, general employing regenerative combustion system, and in order to adjust and control the heating demand of industrial furnace, generally adopt flow detection and control valve to cooperate and carry out.
At present the technology that adopts is: be located at control valve opening size on the pipeline by adjustment, control enters combustion gas and air capacity in the industrial furnace through regenerator, thereby reaches the purpose of temperature in the control industrial furnace burner hearth.
But this mode is because the burning of whole regenerator is outer mixed burning completely, the length of flame is directly related with the instantaneous delivery of regenerator (or spouting velocity), the control valve opening size has changed combustion gas and air sprays into instantaneous delivery in the stove, thereby caused the significant change of the length of flame, thereby caused the uniform distribution of temperature field in the stove to be guaranteed.
Summary of the invention
The purpose of this utility model provides a kind of pulse heat-accumulating industrial furnace, guarantees the uniform distribution of temperature field in the stove.
For achieving the above object, the technical solution of the utility model is:
The pulse heat-accumulating industrial furnace, it comprises, body of heater; Some to burner, be symmetricly set in the body of heater both sides respectively, burner exports corresponding burner hearth of the furnace body; Every pair of burner comprises two heat-accumulating burners, or heat-accumulating burner, another is that non-heat-accumulating burner is formed; Changement comprises the combustion air pipeline that connects burner respectively or gas pipeline, and smoke discharging pipe and control corresponding valve; Wherein, in every pair of burner, a burner connects gas pipeline and smoke discharging pipe, and another burner connects combustion air pipeline and smoke discharging pipe, and corresponding respectively each pipeline is provided with control valve; The programmable logic controller of control takes place in tape pulse, connects the control valve of described changement.
Further, the control valve of described changement is a two way selected valve, or repid cut-off valve.
Again, the control valve of described changement is a three-way diverter valve, connects described gas pipeline, combustion air pipeline and smoke discharging pipe respectively.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is controlled changement by pulse, control flexibility and reliability, uniform distribution of temperature field in the burner hearth.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Referring to Fig. 1, pulse heat-accumulating industrial furnace of the present utility model, it comprises, body of heater 1; Some to burner 2,3,4, be symmetricly set in body of heater 1 both sides respectively, burner exports corresponding burner hearth of the furnace body; Every couple of burner 2(is an example with burner 2) comprise two heat-accumulating burners 21,22; Changement 5 comprises the combustion air pipeline 51 that connects burner respectively or gas pipeline 52, and smoke discharging pipe 53 and control corresponding valve 54,55,56,57; Wherein, every couple of burner 2(is an example with burner 2) in, a burner 21 connects gas pipeline 52 and smoke discharging pipe 53, and another burner 22 connects combustion air pipeline 51 and smoke discharging pipe 53, and corresponding respectively each pipeline is provided with control valve 54,55,56,57; The programmable logic controller 6 of control takes place in tape pulse, connects the control valve 54,55,56,57 of described changement.
In the present embodiment, the control valve of described changement is a two way selected valve.
Again, the control valve of described changement is a three-way diverter valve, connects described gas pipeline, combustion air pipeline and smoke discharging pipe respectively.
When industrial furnace is gone into operation, with each to heat-accumulating burner the load calibration during according to the industrial furnace full production, during ordinary production, temperature control system is according to the needs of fire box temperature, calculate Regenerative Combustion System by PID and should infeed thermic load in the burner hearth (or combustion gas and air moment flow), convert the heating time and the dwell time of the heat-accumulating burner in the pulse period to, make heat-accumulating burner be in the heat supply state by changement (perhaps pulse mechanism) and partly be in halted state at inner branch of a pulse period; Owing to no longer be provided with control valve on the pipeline, in case the heat-accumulating burner heat supply will infeed burner hearth with the load of demarcating, can not reduce because of air (or combustion gas) instantaneous delivery of heat-accumulating burner again and flame is shortened, worsen the distribution in temperature field in the burner hearth.
