Background

Burners are common devices of industrial field boilers, and the burners and pipelines used with the burners and parts of the pipelines, such as valves and switches, constitute a burner system. The operation of the burner system is typically accomplished by an electrical control box.

Fig. 1 shows a flow diagram of a burner system. As shown in fig. 1, the burner system may include a main line and an ignition line for transporting fuel such as gas, an air line for transporting air, and a burner 40. The burner system may further comprise a control device 60 for controlling the operation of the burner system. The control device 60 is a control cabinet.

The air line communicates with the burner 40 for delivering air to the burner 40. The input end of the ignition pipeline is communicated with the main pipeline and is a branch pipeline branched from the main pipeline. The main line, the ignition line, the wind line and the burner 40 are provided with electrical means.

In the illustrated embodiment, the main line may be provided with a filter 11, a manual valve 12, a first fuel valve 13, a leak detection switch 14, a second fuel valve 15, a fuel regulating valve 16 and a flame arrestor 17 from its input to its output. The main line may also be provided with a pressure switch for detecting and controlling the pressure of the fuel, for controlling the pressure of the fuel in the main line. The first fuel valve 13, the leak detection switch 14, the second fuel valve 15, the fuel regulating valve 16, and the pressure switch described above belong to electrical devices.

The pressure switches may include a low pressure switch 18 and a high pressure switch 19. The low-voltage switch 18 is located upstream of the input of the ignition line. A high-voltage switch 19 is located downstream of the input of the ignition line. If the fuel pressure detected by the low-pressure switch 18 is equal to/higher than its preset limit, the low-pressure switch 18 is not actuated; if the fuel pressure sensed by the low pressure switch 18 is below its preset limit, indicating that the fuel pressure is too low, the low pressure switch 18 sends an electrical signal to the control device 60 to cause the program in the control device 60 to trigger the interlock control and then stop the program. If the fuel pressure detected by the high-pressure switch 19 is lower than/equal to its preset limit, the high-pressure switch 19 is not activated; if the fuel pressure detected by the high pressure switch 19 is above a preset limit for the high pressure switch 19, indicating that the fuel pressure is too high, the high pressure switch 19 sends an electrical signal to the control means 60 to cause the program in the control means 60 to trigger the interlock control and then stop the program.

Leak detection switch 14 is used to leak detect at least one of first fuel valve 13 and second fuel valve 15. A leak detection switch 14 is located downstream of first fuel valve 13, and when leak detection of first fuel valve 13 is required, fuel is admitted to the line upstream of first fuel valve 13 when first fuel valve 13 is closed. The second fuel valve 15 and the fuel adjusting valve 16 are opened for a predetermined time, for example, 5 seconds, and then both are closed. If the fuel pressure detected by the leak detection switch 14 is lower than/equal to its preset limit, indicating that the first fuel valve 13 is not leaking, the leak detection switch 14 is not actuated. If the fuel pressure detected by the leak detection switch 14 is higher than the preset limit value, indicating that the first fuel valve 13 leaks, the leak detection switch 14 transmits an electric signal to the control device 60, and the electric signal can enable the program in the control device 60 to trigger the interlocking control and then stop the program; the first fuel valve 13 is then checked for a leak.

The leak detection switch 14 is located upstream of the second fuel valve 15, and when leak detection of the second fuel valve 15 is required, the upstream side line of the second fuel valve 15 is made to enter fuel when the second fuel valve 15 is closed. The first fuel valve 13 is then closed, detected for a predetermined time, e.g. 5 s. If the fuel pressure detected by the leak detection switch 14 is equal to/above its preset limit, indicating that the second fuel valve 15 is not leaking, the leak detection switch 14 is deactivated. If the fuel pressure detected by the leak detection switch 14 is lower than its preset limit, indicating that the second fuel valve 15 is leaking, the leak detection switch 14 sends an electrical signal to the control device 60, and the electrical signal enables the program in the control device 60 to trigger the interlock control and then stop the program; the second fuel valve 15 is then checked for leaks.

The air line is provided with a fan 31 and a wind pressure switch 32 and a wind amount adjusting valve 33 downstream of the fan 31. The ignition valve 22, the fan 31, the wind pressure switch 32, and the wind amount adjusting valve 33 belong to an electric device. The wind pressure switch 32 is used to detect the pressure of wind. If the wind pressure detected by the wind pressure switch 32 is equal to or higher than the preset limit value, which indicates that the fan 31 is normally operated, the wind pressure switch 32 does not act; if the wind pressure detected by the wind pressure switch 32 is lower than the preset limit value, which indicates that the fan 31 is out of order, the wind pressure switch 32 transmits an electric signal to the control device 60 to make the program in the control device 60 trigger the interlock control and then stop the program.

The burner 40 is provided with a lighting device as an electrical device, which may include, for example, a high-energy discharge control box 41 and a high-energy ignition gun 42, and a flame detection device 44, and the high-energy discharge control box 41 is connected to the high-energy ignition gun 42 through a high-voltage cable 43. The flame detection device 44 may be, for example, an ultraviolet/infrared integrated flame detector. The burner 40 is disposed within the boiler 50.

The control device 60 may be used to adjust the load of the combustor 40, for example to increase the load, decrease the load and keep the load constant.

A safety circuit may also be provided between the control device 60 and the field electrical device. For example, a furnace level gauge and a furnace pressure sensor are provided in the boiler 50. The control device 60 is connected with the furnace pressure sensor through a safety loop furnace liquid level meter. The control device 60 may be started by a remote DCS (distributed control system) in the upper computer. The remote DCS is provided with a program starting switch and a burner starting switch. When the program start switch is triggered, the program in the control device 60 starts to run. The safety loop is closed before the program start switch is triggered. When the burner start switch is activated, the control device 60 starts and stops the burner 40 in response to a signal generated after the burner start switch is activated.

In order to debug a program in the control device 60, the present invention provides an emulation debugging device 100. The emulation debugging apparatus 100 and the control apparatus 60 can be connected to each other in communication, for example, the emulation debugging apparatus 100 is connected to the control apparatus 60 through a circuit.

Specifically, the program start switch indicator light 162 is turned on when power is turned on, corresponding to the state where the program start switch is turned on, and is turned off when power is turned off, corresponding to the state where the program start switch is not turned on.

The emulation debugging apparatus 100 may further include a safety loop transfer switch 163 and a safety loop indicator lamp 164. The safety circuit changeover switch 163 is used to simulate the closing and opening of the safety circuit, and is configured to change over between a normal position corresponding to the safety circuit indicator lamp 164 being energized and a fault position corresponding to the safety circuit indicator lamp 164 being de-energized. The safety loop switch indicator light 164 is used to indicate the simulated status of the safety loop. Specifically, the safety circuit indicator lamp 164 is turned on when energized, which corresponds to a closed safety circuit state, and is turned off when de-energized, which corresponds to an open safety circuit state.

The emulation commissioning device 100 may further include a burner activation changeover switch 165 for simulating a burner activation switch. The burner start switch 165 is configured to switch between a start position and a stop position, wherein the start position corresponds to a state in which the burner start switch is activated, and the burner 40 is started; the stop position corresponds to a state in which the burner start switch is not activated and the burner 40 is stopped.

The method of debugging the control device 60 using the emulation debugging device 100 is described in detail below.

The emulation debugging apparatus 100 is connected to the control apparatus 60 by a wire.

The safety loop switch 163 is switched to the normal position and the program in the control device 60 causes the safety loop indicator light 164 to illuminate, which simulates closing the safety loop. The safety loop switch 163 is switched to the fault position and the program causes the safety loop indicator light 164 to be unlit, a process that simulates breaking the safety loop. The program can determine whether the safety circuit is normal based on the signal after the safety circuit changeover switch 163. Specifically, when the safety circuit changeover switch 163 is shifted to the normal position, the program judges that the safety circuit is normal, causes the safety circuit indicator lamp 164 to light up, and when the safety circuit changeover switch 163 is shifted to the normal failure position, the program judges that there is a failure in the safety circuit, and then the program triggers the interlock control and thereafter stops the program.

The program start switch 161 is switched to the start position, at which time a program start signal is generated and the program causes the program start switch indicator light 162 to illuminate. This process simulates the start of a program in the control device 60 by a remote DCS of the upper computer. In response to the program start signal, the program in the control device 60 starts to run.

Burner activation switch 165 is then switched to the activated position, at which time control apparatus 60 causes the programming within control apparatus 60 to enter the burner 40 activation step in response to an electrical signal following burner activation switch 165. The program first performs the step of starting the fan 31. The simulation debugging apparatus 100 responds to a signal for starting the fan 31, and the wind indicator lamp 131 is lighted, and this process simulates starting the fan 31. The wind pressure switch 133 is switched, and the process simulates the wind pressure switch 32 to detect the wind pressure. The wind pressure switch 133 is switched to the normal position, and the process simulates that the wind pressure switch 32 detects that the wind pressure is equal to or higher than the preset limit value; and the program causes the wind pressure switch indicator lamp 134 to light up for indicating the simulation state of the normal operation of the fan 31. The wind pressure switch 133 is switched to the fault position, and the process simulates that the wind pressure detected by the wind pressure switch 32 is lower than the preset limit value; and the program causes the wind pressure switch indicator lamp 134 to be unlit for indicating the simulation state of the fan 31 having a fault.

The program in the control device 60 can determine whether the fan 31 is normally operated according to the signal obtained by switching the wind pressure switch 133. Specifically, when the wind pressure switch 133 is switched to the normal position, the program can determine that the fan 31 is normally operated; when the wind pressure changeover switch 133 is switched to the failure position, the program can determine that there is a failure in the fan 31, and then the program in the control device 60 triggers the interlock control and then stops the program.

The program may execute the step of controlling the opening degree of the air volume adjusting valve 33, at which time the air volume adjusting valve opening degree display screen 132 displays the preset value of the adjusting valve opening degree in the program.

The program may then perform a leak detection step. The program first causes the first fuel valve indicator 111 and the second fuel valve indicator 112 to be unlit to simulate that the first fuel valve 13 and the second fuel valve 15 are not open, i.e., are in a closed state. Then, the opening display 113 of the fuel regulating valve is made to display 100%, and at this time, the fuel regulating valve 16 is indicated to be opened to a 100% simulated opening state; while the second fuel valve indicator lamp 112 is illuminated to simulate opening the second fuel valve 15. The program then causes the fuel regulator valve opening display 113 to display 0%, at which time the simulated state of fuel regulator valve 16 closing is indicated; while the second fuel valve indicator lamp 112 is extinguished to simulate closing of the second fuel valve 15.

Leak detection switch 118 is then toggled, which simulates leak detection switch 14 to detect if first fuel valve 13 is leaking. The leak detection switch 14 is switched to the first position and the program causes the leak detection switch indicator light 119 to illuminate for indicating a simulated condition of a leak in the first fuel valve 13. The leak detection switch 14 is switched to the second position and the program causes the leak detection switch indicator light 119 to be unlit for indicating a simulated condition of no leak from the first fuel valve 13. The program can determine whether the first fuel valve 13 is leaking based on the signal after switching the leak detection switch 14. If it is judged that the first fuel valve 13 is leaking, then the program in the control device 60 triggers the interlock control and then stops the program. If the first fuel valve 13 is judged not to leak, the program first causes the first fuel valve indicator 111 and the second fuel valve indicator 112 to be unlit, causes the fuel regulating valve opening display 113 to display 0%, and then causes the first fuel valve indicator 111 to be lit.

The leak detection switch 118 is then toggled, which simulates the leak detection switch 14 to detect if the second fuel valve 15 is leaking. The leak detection switch 14 is switched to the first position and the program causes the leak detection switch indicator light 119 to illuminate for indicating a simulated condition of no leak from the second fuel valve 15. The leak detection switch 14 is switched to the second position such that the leak detection switch indicator light 119 is not illuminated to indicate a simulated condition of a leak in the second fuel valve 15. The program can determine whether the second fuel valve 15 is leaking based on the signal after switching the leak detection switch 14. If it is judged that the second fuel valve 15 is leaking, then the program in the control device 60 triggers the interlock control and then stops the program. If it is determined that the second fuel valve 15 is not leaking, the leak detection is complete.

After leak detection is complete, the routine may perform an ignition step. The program causes the ignition valve indicator lamp 121 to light up, which simulates opening the ignition valve 22. The ignition lamp 141 is then turned on, and this operation simulates the operation of starting the ignition device to ignite. The flame detection switch 143 is then switched, simulating the detection of a flame by the flame detection device 44. The flame detection switch 143 is switched to the successful position and the program causes the flame detection indicator light 142 to illuminate, indicating that the ignition was successful. The flame detection switch 143 is switched to the failed position and the program causes the flame detection indicator light 142 to be unlit, indicating a failed ignition. The program can determine whether ignition is successful based on the signal from the flame detection switch 143. If the program judges that the ignition is successful, the ignition valve indicator lamp 121 is turned on, the main ignition input step is executed, and if the program judges that the ignition is failed, the ignition valve indicator lamp 121 is turned off, and the ignition step is executed again.

After ignition is successful, the program causes the first fuel valve indicator 111 and the second fuel valve indicator 112 to light up and the fuel adjustment valve opening display 113 displays a preset value, such as 10%. The flame detection changeover switch 143 is then switched. The flame detection switch 143 is switched to the success position and the program causes the flame detection indicator light 142 to light, indicating that the main fire was successfully delivered. The flame detection switch 143 is switched to the fail position and the program causes the flame detection indicator light 142 to illuminate, indicating that the main fire was successfully delivered. The program can determine whether the main fire is successfully applied based on the signal from the flame detection switch 143. If the program judges that the main fire input fails, the first fuel valve indicator lamp 111 and the second fuel valve indicator lamp 112 are turned off, the opening display screen 113 of the fuel regulating valve displays 0 percent, and the ignition step is executed again.

After the main fire is successfully delivered, the routine may execute the step of adjusting the load on the burner 40. A load change-over switch 151 for changing over the load change-over switch 151 from a load-unchanging change-over position to a load-increasing change-over position, in which the load is increased in a simulated manner, and a program lights a load increase indicator lamp 152; the load adjustment changeover switch 151 is switched to a load reduction changeover position, the process simulates the load reduction, and the program causes the load reduction indicator lamp 153 to be turned on; the load control switch 151 is switched to a load-invariant switching position, which simulates the operation of the burner 40 at the current load.

After the main fire is successfully delivered, the routine may perform the step of fuel pressure monitoring. The low pressure switch 114 is switched and the process simulates the low pressure switch 18 monitoring the fuel pressure. Switching the low pressure switch 114 to the normal position, simulating the low pressure switch 18 detecting that the fuel pressure is equal to/higher than its preset limit; and the program causes the low pressure switch indicator lamp 115 to light up for indicating a simulated condition that the fuel pressure is normal. Switching the low pressure switch 114 to the fault position, simulating the low pressure switch 18 detecting that the fuel pressure is below its preset limit; and the program causes the low pressure switch indicator 115 to be unlit for indicating a simulated condition where the fuel pressure is too low.

The program in control device 60 can determine whether the fuel pressure is lower than the preset lower limit value based on the signal after switching low pressure switch 114. Specifically, when the low pressure switch 114 is switched to the normal position, the routine can judge that the fuel pressure is equal to/higher than a preset lower limit value, and the fuel pressure is normal; when the low pressure switch 114 is switched to the failure position, the routine can judge that the fuel pressure is lower than the preset lower limit value, there is a failure, and then the routine in the control device 60 triggers the interlock control and then stops the routine.

The high pressure switch 116 is switched and the process simulates the high pressure switch 19 monitoring the fuel pressure. Switching the high-pressure switch 116 to the normal position, simulating the high-pressure switch 19 detecting that the fuel pressure is lower than/equal to its preset limit; and the program causes the high-pressure switch indicator lamp 117 to light up for indicating a simulated state where the fuel pressure is normal. Switching the high voltage switch 116 to the fault position, simulating the high voltage switch 19 detecting that the fuel pressure is above its preset limit; and the program causes the high pressure switch indicator lamp 117 to be unlit for indicating a simulated condition where the fuel pressure is too high.

The program in control device 60 can determine whether the fuel pressure is higher than the preset upper limit value based on the signal after switching high-pressure switch 116. Specifically, when the high-pressure switch 116 is switched to the normal position, the program can determine that the fuel pressure is lower than/equal to the preset upper limit value, and the fuel pressure is normal; when the high-pressure switch 116 is switched to the failure position, the program can judge that the fuel pressure is higher than the preset upper limit value, there is a failure, and then the program in the control device 60 triggers the interlock control and then stops the program.
