Introduction: Ultra-low emission refers to the integrated system technology of efficient and coordinated removal of multiple pollutants in the process of power generation operation and terminal treatment of coal-fired boilers in thermal power plants, so that their atmospheric pollutant emission concentrations basically meet the emission limits of gas-fired units The emission concentration of soot, sulfur dioxide, and nitrogen oxides (base oxygen content of 6%) shall not exceed 5 mg / m³, 35 mg / m³, and 50 mg / m³, respectively, which is higher than the “Emission Standard of Air Pollutants for Thermal Power Plants” (GB13223-2011) The special emission limits for key areas of coal-fired boilers specified in this document have fallen by 50%, 30% and 50% respectively, and are the new benchmark for cleaner production levels of coal-fired generating units. Against this background, Xi'an Juneng Instrument Co., Ltd. has successfully developed the TR-9300D flue gas ultra-low emission continuous monitoring system based on years of experience in the development and application of environmental monitoring systems. The system is based on HJ / T76-2007, HJ / T75-2007 and other relevant standards and specifications. Its analytical instrument uses the JNYQ-S-81 type flue gas analyzer independently developed by Xi'an Juneng Instrument Co., Ltd., and a single set of monitoring system The architectural mode of the monitoring platform probe + pretreatment + industrial control computer + LCD display + data acquisition instrument completes the functional requirements for the reception, storage, display and transmission of monitoring data.
