Title:
COMBUSTION STATE EVALUATION METHOD AND COMBUSTION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/075490
Kind Code:
A1
Abstract:
This combustion state evaluation method includes: a formation step; a division step; a first calculation step; a second calculation step; a third calculation step; an identification step: a determination step; and a first evaluation step. In the formation step, a three-dimensional thermal image is formed by observing a waste deposited on at least a combustion unit. 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 moving speed of the waste are calculated for each of the elements. In the second calculation step, thickness progress information is calculated for each of the elements. In the third calculation step, volume flowrate progress information is calculated for each of the elements. In the identification step, a combustion-in-progress element is identified. In the determination step, the degree of progress of combustion is identified, and a combustion correction coefficient based on the degree of progress is determined. In the first evaluation step, a heat amount index is calculated.
