AI Technical Summary

Problems solved by technology

The dust content of boiler flue gas is high, and the flue gas has strong erosion and wear effect. The test system for high ash flue gas composition of boilers needs to fully consider its test characteristics to adapt to the test conditions of boilers. Currently, the test for high ash flue gas composition of boilers The system does not fully consider the test conditions of the boiler's high ash and flue gas components, and its adaptability to the boiler is poor, which affects its test accuracy

Abstract

The invention provides a system for testing high-ash flue gas composition of a boiler, which is used for testing the flue gas composition in a boiler flue. The system comprises: two ends of a testing pipeline comprise a sampling end and an analyzing end respectively, wherein the sampling end is provided with a flue gas sampling gun and a filtering probe stretching into the boiler flue is arranged at one end part of the flue gas sampling gun; the analyzing end is provided with a flue gas analyzer; a gas-solid separation assembly and a water removing assembly are arranged between the sampling end and the analyzing end in sequence. The system provided by the invention can be adaptive to characteristics of high dust content of flue gas of the boiler, high erosion effect of the flue gas and the like; an accurate measured result is obtained, and stability and safety of the operation of a measuring instrument are ensured.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a system for testing components of high ash flue gas of boilers. Background technique [0002] With the development of my country's national economy and the improvement of environmental protection awareness, the air pollution emission standards of coal-fired power plants in my country have become stricter year by year, and the nitrogen oxide emission standards of coal-fired boilers have also become increasingly strict. In July 2011, the state promulgated the "Emission Standard of Air Pollutants for Thermal Power Plants (GB 13223-2011)", requiring existing coal-fired power plants to implement 100mg / m of nitrogen oxides from July 1, 2014 3 In September 2014, the National Development and Reform Commission, the Ministry of Environmental Protection and the National Energy Administration jointly issued the "Coal Power Energy Conservation and Emission Reduction Upgrade and Tr...
