A refined calculation of the non-stationary temperature walls a rotary kiln is proposed, taking into account thermal conductivity in enclosing and accumulation heat them, intended for use numerical simulation combustion transfer processes. The influence on alternating contact inner surface with gaseous medium layer technological material considered. adequacy method was verified by solution diff...

This paper presents a systematic approach for development of a data-driven soft sensor using robust statistical technique. Data preprocessing procedures are described in detail. First, a template is defined based on a key process variable to handle missing data related to severe operation interruption. Second, a univariate, followed by a multivariate principal component analysis (PCA) approach,...

There are many factors that can affect the calciner process of cement production, such as highly nonlinearity and time-lag, making it very difficult to establish an accurate model of the cement precalciner kiln (PCK) system. In order to reduce transport energy consumption and to ensure the quality of cement clinker burning, one needs to explore different control methods from the traditional way...

With the fast evolution in greenhouse gas (GHG) emissions (e.g., CO2, N2O) caused by fossil fuel combustion and global warming, climate change has been identified as a critical threat to sustainable development of human society, public health, environment. To reduce GHG emissions, besides minimizing waste heat production at source, an integrated approach should be adopted for management, namely...
