Control of Pollutant Emissions from a Boiler Through the Percentage of Oxygen

Abstract

The goal of this paper is to obtain an automated system for the control of the quality of the combustion gases of a boiler. The concentration of oxygen present in the combustion gases is detected by means of a lambda sensor, and a proportional PID controller automatically regulates, through an actuator, the air inlet to the boiler, thus ensuring the emission of CO2 and other polluting gases into the atmosphere within the parameters established by the current environmental regulations. The control system has an HMI display and a modular PLC. The results achieved also ensure the reduction of fuel consumption of the boiler.

Traceability of River Water Pollution Based on MFO and M-H Algorithms

“…Research on water pollution incidents focuses on spatio temporal dynamic changes in water quality [8,9], pollution causes [10], pollutant sources [11][12][13], and the traceability of water pollution sources [14][15][16][17][18][19]. Accidental pollutants will convene and spread in the river as water pollution incidents happen.…”
