Abstract

The heat balance algorithm can evaluate the influence of a individual factor alone, and overall economic influence can be calculated through simulation. Therefore, the heat balance algorithm can be the basis of our weighting algorithm research, helping us to find the relationship between data. Calculating the effect of a individual factor on the economics of the unit also grasps the level of influence of a certain factor change on the overall unit. The purpose of studying the weighting algorithm is to analyse the effect of the above factors economically and analyse the association among them. With the three and four transformation measures, by validating the data, it is found that based on the heat consumption income of individual transformation measures: back pressure optimization < cylinder efficiency improvement < waste heat utilization < low pressure cylinder efficiency improvement < medium pressure cylinder efficiency improvement < High pressure cylinder efficiency improvement < external steaming cooler. The heat consumption benefit value of the above-mentioned transformation technical scheme can be calculated based on the maximum benefit (back pressure optimization transformation).
