Combustion flue gas analyzer helps reduce emissions and improve combustion efficiency

摘要

Emerson has released its Rosemount Analytical 6888 in-situ 02 analyzer. This analyzer provides accurate measurement of oxygen remaining in flue gases coming from combustion processes such as boilers, incinerators, kilns, process heaters, and industrial furnaces. By maintaining the ideal level of oxygen, optimal efficiency is achieved and the lowest levels of NOx, CO, and CO2 are produced. The new design places ~ a zirconium oxide sensing element directly into a flue gas stream. Probe lengths are available from 18 in. to 12 ft, and a slip mounting option permits mounting a long probe at any insertion depth. Signal conditioning electronics reside in the head of each probe, eliminating the need for expensive signal cable. The 6888 is fully field-repairable. All active components can be replaced including the diffuser/filter, sensing cell, heater, thermocouple, and all electronics cards.
