DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016]
[0017] Burner 102 provides heat necessary to perform chemical reactions or heat up process fluid in one or more process tubes 108 (not all of which are labeled in
[0018] Throughout the heater 104 are a plurality of sensors that transmit data to a process controller 124. The sensor data is stored in a sensor database 126. The sensors 122 include a variety of sensors known in the art, such as O.sub.2 sensor, NOX sensor, CO sensor, pressure sensor, air-flow sensors, fuel-flow sensors, temperature sensors, laser-based sensors, optical-based sensors, etc. The process controller 124 is a distributed control system (DCS) (or plant control system (PLC) used to control various systems throughout the system 100, including fuel-side control (e.g., control of components associated with getting fuel source 110 into the heater 104 for combustion therein), air-side control (e.g., control of components associated with getting air source 112 into the heater 104), internal combustion-process control (e.g., components associated with managing production of the thermal energy 114, such as draft within the heater 104), and post-combustion control (e.g., components associated with managing the emissions after production of the thermal energy 114 through the stack section 120). The process controller 124 typically includes many control loops, in which autonomous controllers are distributed throughout the system 100 (associated with individual or multiple components thereof), and including a central operator supervisory control. The control signals generated by the process controller 124 are based on the data provided by the sensors 122, and external data such as weather data, etc.
[0019] In addition to the draft within the heater, burner geometry plays a critical role in managing the thermal energy 114 produced in the heater 104. Typically, burners are specifically designed to have a static geometry that does not change (e.g., burner shape is consistent to the designed configuration, (except for wear and tear impact such as tip plugging, tip burn-off, failing refractory, etc.). The present embodiments address the realization operating conditions change within the heater 104. These changing operating conditions make it desirable to change the flame shape and/or direction (represented in

[0022] The variable-direction burner tip assembly 200 includes a variable-direction burner tip 202 that is coupled, directly or indirectly, with a fuel input 204. Fuel input 204 is shown angled with respect to the X-axis, but it may be parallel thereto without departing from the scope hereof. The fuel input 204 is coupled to a rigid pipe 206, such as a steel gas pipe that is of the standard piping used in a combustion system burner. The rigid pipe 206 spans a first mounting plate 208 and a second mounting plate 210. The rigid pipe 206 may pass through the first mounting plate 208 and/or the second mounting plate 210, as shown in
[0023] The hose coupler 214 (or another portion of the burner tip 202) is coupled to a rotator assembly 216. The rotator assembly 216 is a mechanical or electrical (e.g., servo) device that varies the direction of the burner tip 202. The rotator assembly 216 is shown as a mechanical rotator that varies the direction of the burner tip 202 in the Y-axis. However, the rotator assembly 216 may be a different type of mechanical rotator, that rotates the burner tip 202 about more than one axis, such as each of the X-, Y-, and Z-axis. Moreover, the rotator may include a translation component that moves the burner tip 202 along one or more of the X-, Y-, and Z-axis (e.g., that moves the burner tip 202 further into the combustion system space, or back into the burner housing).
[0024] In
[0025] The support brace 502 is fixedly mounted to the second mounting plate 210, and thus maintains the first hinge bar 218 at a given location. The support brace 502 includes a first side 602 and a second side 604 coupled to the second mounting plate 210. The first and second sides 602 and 604 are also supported to each other via a top plate 606.
[0026] The first linkage arm 222 is coupled to a second linkage arm 226. The second linkage arm 226 is shown including a linkage-arm coupler 228, a first linkage-arm component 230, an off-set plate 232, and a second linkage-arm component 234. Second linkage arm 226 is further coupled to an actuator 236.
[0027] Second linkage arm 226 may be a metal rod, plate, or any other mechanical device that allows for horizontal movement of the second linkage arm 226 in response to interaction with actuator 236, as discussed below. Off-set plate 232 allows for a greater vertical spacing (e.g., along Y-axis in
[0028] Actuator 236 is a threaded rod (or otherwise a nut) coupled to the second linkage arm 226 via an actuator coupler 239. As the actuator 236 is rotated in a clockwise or counterclockwise direction, the second linkage arm 226 translates along the X-axis.
[0029] The variable-direction burner tip assembly 200 may further include a rotation indicator 238. The rotation indicator 238 correlates the position of the actuator 236 to the firing direction of the burner tip 202. Because the burner tip 202 is in the heater, it is not readily visible to the operator. Therefore, the rotation indicator 238 allows the operator to understand the position of the burner tip 202.
[0030] Referring back to
[0031]
[0032] In block 902, method 900 receives data from one or more sensors within a combustion system. In one example of block 902, the heater controller 124 receives, and stores within sensor database 126, data from one or more of the sensors 122 within the combustion system 100 defining operating conditions of the combustion system.
[0033] In block 904, method 900 outputs a control signal to change a flame shape of one or more burners within the combustion system. In one example of operation of block 904, the heater controller 124 outputs a control signal 128 to change the flame shape output by burner 102.
[0034] In block 906, the method 900 actuates at least one actuator to vary direction of one or more burner tips on one or more burners within the combustion system. In one example of operation of block 906, the actuator 236 is manually rotated to vary the position of the burner tip 202 to a desired pointing direction as indicated by rotation indicator 238. The control signal from block 904 may indicate the amount of actuation of actuator 236 may be displayed to the operator one a display of an operator device (e.g., control display on heater controller 124, display on a mobile operator device such as a tablet or smartphone, etc.). In one example of operation of block 906, the actuator 236 is electronically rotated based on the control signal from block 904.
