Study on mercury oxidation by SCR catalyst in coal-fired

01/12/2017 · Methods and Experiments The research object is a domestic 300MW coal-fired utility boiler which has been equipped with SCR to control NOx emission and uses honeycomb V2O5-WO3/TiO2 catalyst. During the process of test, the species and concentration of the mercury in flue gas before and after SCR are sampled and analyzed by OHM.

Typical applications for the Infrasound Cleaning in coal fired boilers are Economizers, Air Preheaters (Ljungstrom, Rothemuhle, tubular) and SCR catalysts. Our HISS™ system for optimizing steam soot blowing is used for saving soot blowing steam or increasing cleaning effect,

The effect of SCR on design of flue gas systems - Boiler

In this paper, recent advances in the formation, transformation, measurement, and control mechanism and technologies of SO 3 in coal-fired power plants were summarized. The formation mechanisms of SO 3 in boiler and SCR systems and its form transition and corresponding effects on the performance of power plants were analyzed.
