1. Control Panel: The sequence controller is typically housed in a control panel that contains all the necessary components for controlling the burner sequence.

2. Microprocessor or PLC: The heart of the sequence controller is a microprocessor or a programmable logic controller (PLC). This component executes the control logic programmed into the system and coordinates the operation of the burners.

3. Input/Output Modules: Input modules receive signals from sensors and switches, such as temperature sensors, pressure switches, flame detectors, and interlocks. Output modules control the actuators and devices, such as solenoid valves, motors, and ignition transformers.

4. Start-Up Sequence: The sequence controller initiates the start-up process of the burner system. This typically involves tasks such as purging the combustion chamber of any residual gases, pre-purging the combustion air, and establishing the ignition source.

5. Safety Checks: Before allowing the burner to ignite, the sequence controller performs safety checks to ensure that conditions are safe for combustion. These checks may include verifying the presence of proper combustion air flow, fuel pressure, and absence of flame before ignition.

6. Ignition Control: Once safety checks are completed, the sequence controller energizes the ignition system, which may include spark igniters, pilot lights, or glow plugs, depending on the burner design.

7. Flame Monitoring: During operation, the sequence controller continuously monitors the presence of the flame using flame detectors or sensors. If the flame is extinguished for any reason, the controller initiates safety shutdown procedures to prevent the release of unburned fuel into the combustion chamber.

8. Burner Sequencing: In systems with multiple burners, the sequence controller manages the firing sequence to optimize efficiency and maintain consistent heat output. This may involve rotating the operation of individual burners to distribute wear and ensure even heating.

9. Shutdown Sequence: When the heating process is complete or if a fault condition occurs, the sequence controller initiates the shutdown sequence. This includes extinguishing the burner flame, purging the combustion chamber of any remaining gases, and closing fuel and air valves.

10. Diagnostic and Status Indicators: The control panel typically includes diagnostic indicators and status lights to provide feedback on the operation of the burner system. This helps operators identify any issues or faults that may require attention.

The oil burner photocell is a critical component in oil-fired heating systems, serving as a sensor to detect the presence or absence of the burner flame. Here's a description of its features and functions:

Flame Detection: The primary function of the photocell is to detect the presence of the burner flame during operation. It serves as a safety device to ensure that the burner ignites properly and that the flame remains stable throughout the heating cycle.

Photodetector: The photocell contains a photodetector, typically a photodiode or phototransistor, which reacts to the infrared radiation emitted by the burner flame. When the flame is present, the photodetector generates an electrical signal indicating that combustion is occurring.

Safety Interlock: The photocell is often integrated into the burner's safety control system. If the photocell does not detect a flame when the burner is active, it sends a signal to the control system to shut down the burner immediately. This safety interlock prevents the release of unburned fuel oil into the combustion chamber, reducing the risk of fire or explosion.

Reliability: Photocells are designed for reliable performance in demanding environments, with robust construction and high sensitivity to detect even small flame signals. They are engineered to withstand the heat and vibration typically encountered in oil burner applications.

Adjustability: Some photocells feature adjustable sensitivity settings, allowing technicians to fine-tune the detection threshold to suit specific burner configurations and operating conditions. This adjustability helps optimize flame detection performance and minimize false alarms.

Maintenance: Regular inspection and cleaning of the photocell are essential to ensure proper operation. Dust, dirt, or oil residue can accumulate on the photocell's lens, impairing its sensitivity and reducing its ability to detect the flame accurately. Routine maintenance helps maintain reliable flame detection and overall burner performance.

Compatibility: Photocells are compatible with a wide range of oil burner models and designs. They are available in various shapes, sizes, and mounting configurations to accommodate different burner configurations and installation requirements.
