Pellet Combustion Control via Sensor Feedback Curves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pellet and biomass combustion apparatuses face inefficiencies and increased atmospheric pollution due to the complex and costly process of adjusting operating parameters like vacuum, smoke temperature, and ambient temperature, which are typically set initially and not easily modified in response to changing environmental conditions, often leading to suboptimal performance and increased operational costs.
Innovation Solution
A method and apparatus that utilize sensors and a CPU with feedback control to automatically adjust and correlate all operating parameters, including internal and external temperature, smoke temperature, vacuum, and oxygen levels, ensuring optimal performance by continuously monitoring and interlinking adjustments through correlation curves and signal processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If individual parameters are adjusted independently through feedback control, then each parameter can be controlled separately, but the overall combustion efficiency is not optimal
Solution Approach 1:
The patent merges the control of multiple combustion parameters (vacuum, smoke temperature, oxygen quantity, ambient temperature) into a single integrated control system. The CPU receives signals from sensors measuring all these parameters and processes them together to generate coordinated control signals, ensuring that parameters are adjusted in a synergistic manner rather than independently, thereby optimizing overall combustion efficiency.
2Ease of manufacture
If pre-set operating parameters are used during testing, then initial combustion results can be established, but the parameters cannot be corrected when environmental conditions change
Solution Approach 1:
The patent implements a feedback control system where sensors continuously measure operating parameters (vacuum, smoke temperature, oxygen quantity, ambient temperature) and feed this information back to the CPU. The CPU processes these feedback signals and automatically adjusts the combustion parameters in real-time to adapt to changing environmental conditions, eliminating the need for manual reconfiguration by specialized staff.
Solution Approach 2:
The control system is designed to be self-regulating, automatically adjusting combustion parameters without requiring external intervention. The CPU autonomously processes sensor data and modifies operating parameters based on pre-programmed logic, enabling the system to adapt to environmental changes independently rather than requiring specialized technical staff for modifications.
3Adaptability or versatility
If specialized technical staff modify control parameters, then parameter adjustments can be made, but the procedure is complex and expensive
Solution Approach 1:
The control system is designed to be self-regulating, automatically adjusting combustion parameters without requiring external intervention. The CPU autonomously processes sensor data and modifies operating parameters based on pre-programmed logic, enabling the system to adapt to environmental changes independently rather than requiring specialized technical staff for modifications.

AI summary
The present invention concerns a combustion apparatus (1; 20) comprising: a combustion chamber (2); an exhaust circuit with fan for the forced extraction of the smokes, connected to the combustion chamber (2); a plurality of sensors suited to detect the operating conditions of the apparatus (1; 20); a combustion control unit (3). The control unit (3) is provided with one or more input ports for signals emitted by the sensors connected to the input ports, and one or more output ports for signals intended to control the means that supply the fuel-comburent mixture into the combustion chamber (2) and the smoke extraction means. The control unit (3) has feedback controls based on curves providing a correlation with the values measured by the sensors. The present invention also comprises a method for the operation of the combustion apparatus that constitutes an integrated system, in which all the operating parameters can be adjusted automatically and are correlated with each other so that modifying one of them means modifying all the others.
