Problems solved by technology

Most of the current research direction is to analyze and study the thermal efficiency of the cement clinker firing process from an overall perspective. When the thermal efficiency model participates in the actual calculation on site, as the production continues, some parameters appear to be mismatched, resulting in the cement clinker firing process. There is a phenomenon that the thermal efficiency is greatly reduced in the

Abstract

The invention discloses a method and device for evaluating and calibrating parameters for on-line calculation of thermal efficiency of a cement rotary kiln. The method comprises the following steps: calculating a quality threshold of deviation thermal efficiency parameters during frequent operation of the cement rotary kiln; Standard deviation of thermal efficiency parameters; compare the standard deviation of real-time thermal efficiency parameter calculation with the quality threshold of deviation thermal efficiency parameters, and determine the parameter data for thermal efficiency calculation of cement rotary kiln; correction calculation of secondary air intake into the kiln. The invention not only successfully solves the problem of mismatch of some parameters as the production continues when the thermal efficiency model participates in the actual calculation on site, but also ensures the accuracy of the thermal efficiency model calculation and improves the thermal efficiency in the cement clinker firing process. The accuracy of online calculations.

Description

technical field [0001] The invention relates to a method and a device for evaluating and calibrating parameters for on-line calculation of thermal efficiency of a cement rotary kiln, belonging to the technical field of energy conservation and emission reduction of cement production lines. Background technique [0002] The cement industry is one of the important industries of my country's national economy. The construction of intelligent cement factories and the improvement of the digital, intelligent and green level of cement enterprises have become the main development direction of the cement production industry.
