Oil burner control AC110V LAL2.25-110V PLC Module

Overview

LAL2.25 – 110V is a heavy oil atomization burner controller, specially designed for the control and monitoring of medium and high capacity heavy oil atomization burners. It is suitable for a variety of industrial combustion scenarios. It is suitable for intermittent operation of multi-stage or proportional adjustment burners. It can also be adapted to fixed air heaters. It has an air pressure monitoring function and can realize controllable adjustment of the damper. It also undertakes monitoring tasks related to flame protection to ensure the stability and safety of the combustion process.

FAQ:

1.Can the output current of LAL2.25-110V meet the driving needs of common proportional burners?

The output current of LAL2.25 – 110V can usually meet the driving requirements of common proportional modulating burners. The specific matching degree between its output current parameters and the current demand of the core driving components of the burner is as follows:

1. Output capacity: single channel maximum 4A, total carrying capacity 5A;
2. Matching: The current of core components such as servo motor (3-3.6A) and proportional valve (180-250mA) does not exceed the upper limit;

However, if the burner is an ultra-high-power model and its fan motor and other components are started or the rated current exceeds 4A, an additional relay or contactor expansion is required to ensure stable driving. However, this situation is not common in common proportional adjustment burners.

2.What is the response time of LAL2.25-110V flame protection?

The core response time of LAL2.25 – 110V flame protection can refer to its ignition safety time (TS) of 5 seconds. This parameter determines the safety triggering time when the flame is abnormal:

1. Core response: TS (ignition safety time) up to 5 seconds (cut off fuel within 5 seconds after flame abnormality);
2. Related parameters: pre-purge 22.5 seconds, post-purge 15 seconds;

In addition, it should be noted that under the 60Hz power frequency environment, its various switching times will be shortened by about 17%. At this time, the flame protection response time will also be slightly shortened, which is subject to the actual operating status of the equipment under actual working conditions.

3.What is the pre-purge time for LAL2.25-110V flame protection?

LAL2.25 – 110V flame protection pre-purge time is about 22 seconds. This model is a controller adapted to fuel atomization burners. This pre-purge period can effectively discharge the residual fuel in the furnace, laying a solid foundation for safety for subsequent ignition and combustion processes, and meeting its safety control design requirements for fuel combustion scenarios.
