Disclosed is a control system for controlling the feed of a solid fuel in a combustion process. The system includes a control unit which is adapted to communicate by way of a communications link in the system, to receive from online measuring instruments online measurement data regarding a fuel coming from a fuel reception unit, and to control a feeding unit for delivering the measured fuel into a fuel silo on the basis of its content model and measurement data.

A method for the post-combustion of exhaust gases comprising carbon monoxide from metallurgical processes includes conditioning the exhaust gas prior to post-combustion by metering a combustion gas and/or one additional gas in feedback-controlled fashion. The feedback control depends on the composition of the exhaust gas dependent on the exhaust gas volume flow. A device for post-combustion of exhaust gas during vacuum treatment of liquid steel comprises a flare stack at an exhaust outlet, means for feeding combustion gas to the flare stack, means for feeding an inert gas into the exhaust gas channel of the vacuum pump, means for ascertaining the exhaust gas volume flow and/or for measuring the exhaust gas velocity within the exhaust gas channel, means for analyzing the exhaust gas composition, means for metering the combustion gas and the inert gas, and means for feedback control of the metering of the combustion gas and/or the inert gas dependent on the exhaust gas composition.

Disclosed herein are embodiments of a flare control method and a flare apparatus for automatically controlling, in real-time, the flow of one or more of fuel, steam, and air to a flare. The disclosed embodiments advantageously allow for automated control over a wide spectrum of operating conditions, including emergency operations, and planned operations such as startup and shutdown.

The present application overcomes the disadvantages of the prior art by providing a system for proper life-cycle management of plastic products and the plastic waste that plastic products produce.

A remote sensing system which may be assembled with an Infrared (IR) sensor, or a plurality of IR sensors, disposed to sense IR radiance emitted as combustion products from a flare stack in two distinctive spectral bands, each band having a narrow spectral bandpass, the sensor being radiometrically calibrated to sense transmission characteristics of the two distinctive bands of the radiance from flare combustion gases; and an analyzer driven by a microcontroller, coupled to the IR sensor, to operationally respond in real time by generating an indication of flare stack's performance through a parameter derived from a ratio of the transmission characteristics of the two radiance outputs sensed by the IR sensor. The IR sensor of this flare monitoring-apparatus must be positioned in such a way that the anticipated entire flame will be captured within the Field of View (FoV) of the IR sensor, or sensors.

Systems and methods for monitoring emissions of a combusted gas are provided. The method includes determining a first net heating value of a flare gas. The method also includes determining a second net heating value of a combustion gas including the flare gas. The second net heating value can be determined based upon the first net heating value and a volumetric flow rate of the flare gas. Based upon the value of the second net heating value, an empirical model or a non-parametric machine learning model can be selected. A combustion efficiency of the combustion gas can be determined using the selected model, the second net heating value, and selected ones of the process conditions and the environmental conditions. Total emissions of the combustion mixture can be further determined from the combustion efficiency and a volumetric flow rate of the combustion gas.
