A Soft Measurement Method and Device for Carbon Content of Fly Ash Based on LSSVM
-
Abstract
The carbon content of fly ash is one of the important indexes to reflect the combustion efficiency of boiler in thermal power plant. Real-time and accurate detection of carbon content of fly ash is of great significance for guiding the operation of the boiler and enhancing the efficiency of the boiler. Most of the current detection devices use burning and reflection methods to measure the carbon content of fly ash, this kind of measurement subjects to long lag, low accuracy, high maintenance cost and poor field application effect. In this paper, the ash content of fly ash based on LSSVM was proposed, and the relevant operating parameters of convenience measurement were taken as auxiliary variables. The soft measurement model was used to forecast the carbon content of fly ash in real time. And this paper embeded LSSVM soft sensor system into the PLC, developed a kind of fly ash carbon content on-line soft sensor device which can achieve measurement quickly and accurately without the ash sample.
