Title:
COMBUSTION STATE EVALUATION METHOD AND COMBUSTION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/075487
Kind Code:
A1
Abstract:
A combustion state evaluation method that includes: a creation step, a division step, a first calculation step, a second calculation step, a third calculation step, a determination step, and an evaluation step. In the creation step, waste accumulated in at least a drying section is observed, and a three-dimensional thermal image is created. In the division step, the waste in the three-dimensional thermal image is mesh-divided into a plurality of elements. In the first calculation step, the thickness of the waste and the surface movement speed of the waste are calculated for each element. In the second calculation step, thickness progression information is calculated for each element. In the third calculation step, volumetric flow rate progression information is calculated for each element. In the determination step, the volumetric flow rate progression information is analyzed, and for each element, a determination is made regarding whether the waste is in a state in which combustion can begin. In the evaluation step, a combustion start evaluation position is identified on the basis of the result of the determination in the determination step.
