Assess each kiln and its operating context
The assessment should record dimensions, measurement points, panels, actuators and electrical supply conditions. It should also examine how the team identifies cycle stages and which information operators use when making decisions throughout the production process.
Research published by UFV on temperature control highlights the relevance of observing the thermal behavior of carbonization. In an engineering project, those observations must be linked to the kiln design, the feedstock and the operating procedure approved by the facility.
Separate measurement, supervision and actuation
Instrumentation collects the selected variables. Supervision presents curves, states and events. Automatic actuation depends on specific logic, suitable equipment and process validation. Implementing these functions in stages helps the team understand the contribution and requirements of each layer.
Before enabling commands, define permissive conditions, fault handling and responsibilities. A communication failure must not be treated as confirmation that conditions are normal. The project should establish how local operation continues and how missing records are recovered.
Test while keeping an operational reference
An initial deployment can cover one representative kiln, using monitoring criteria agreed in advance. Compare stage identification, reading availability and record consistency. The team should be able to explain the information displayed on the HMI or supervisory system.
Expansion to other kilns requires a review of physical and operational differences, even when their designs appear similar. Document logic versions, sensor identification and completed tests. Assess the expected result using the plant's own data instead of transferring improvement percentages from unrelated studies.
What to assess for your project
- Record physical and operational kiln characteristics.
- Define measurement points and project objectives.
- Validate permissives and behavior during failures.
- Document the pilot before expanding implementation.
COM3
How COM3 can help
COM3 can support the assessment and engineering of charcoal kiln automation, integrating sensors, PLCs, HMI and supervisory systems. The scope can progress from data collection to validated control, according to the infrastructure, technical analysis and production procedures of the facility.
