Abstract:

Oxygen analyzer LGA-4130 is used for on-line measurement of oxygen content in gas after electro-static tar precipitator (ETP) and for interlock shutdown of the ETP in case of reaching the HH limit of the oxygen value preset on DCS aiming at a safe and stable running of the ETP.The advantages and disadvantages of this analyzing system are studied in this paper,suggestions for improvement are also given.
