Abstract

A system for monitoring fuel consumption in a rotary kiln includes IR sensors and computing systems. The computing systems: obtain a sequence of images; determine a map of temperature values of the infrared images in the sequence of infrared images; obtain a digital model of fuel consumption in relation to temperature values of the rotary kiln, wherein the digital model of the fuel consumption is based on a measured infrared temperature for the infrared images; determine the fuel consumption of the rotary kiln based on the measured infrared temperature with the digital model of the fuel consumption; and provide the fuel consumption in a fuel consumption report. The computing systems: analyze the fuel consumption of the kiln; obtain a correlation factor for the fuel consumption that identifies an amount of carbon dioxide emissions; and determine the emissions for the fuel consumption.
