摘要: Abstract In this paper, an ash-free sampling device of coal-fired flue gas has been developed, including the U-shaped probe, electric heating element and thermostat, ports, porous ceramic filter, which can not only be used for low-ash measurement, but also able to achieve high-ash measurement. The developed work at a wide temperature range from 120 ∼ 650°C. It is adopted conduct field-testing power station measure mercury in derived gas, attained date are satisfactory reflect actual plant emissions level speciation mercury. with simple configuration efficient function, providing effective method tool other pollution emission measurement their control.
