Evonik's long-term SCR catalyst operating and management experience

Author: Schneider, Matthias ; Brueggendick, Hermann

The exchange of SCR-catalysts is the biggest operating expenditure at the SCR reactors Evonik STEAG.Therefore, it is desired to maximize lifetime.Thus, Evonik STEAG has introduced a centralized management catalyst system for the entire power plant fleet.The scope and benefits of this instrument and the operating experience which could be obtained in the last years will be described in the following.A regular catalyst exchange is unavoidable and should be well organized and planned to minimize outage time.Each type of SCR catalyst has its distinctive advantages and disadvantages (plate, honeycomb, chem. and phys. characteristics).The selection of the best catalyst type requires an economic evaluation on a case by case basis.In addition, during reactor inspection and SCR equipment performance monitoring of the DENOX system, numerous features and parameters have to be analyzed, thus the use of SCR knowledge raises a number of optimization approaches.The development of the catalyst regeneration, which has been a major factor in reducing O&M costs for SCR systems, has established itself at many power plants as an inexpensive alternative, unlike the acquisition of new catalysts.

Import coal as a challenge for dust separation in electrostatic precipitators

Author: Rhein, Horst ; Brueggendick, Hermann ; Riethmann, Thomas

The quality of coal which varies due to rising use of import coal has a major influence on the effects in the electrostatic precipitator (ESP).The understanding of the theor. background in the ESP is giving the fundamentals for the characterization of the separation behavior in dependence of the used coal.The dust separation in the ESP was investigated for a range of different import coals regarding different local conditions.In this study, the possible future fuel supply regarding the emission limit for power plants designed for German hard coal is rated.Within that scope, the primary retention of ash in wet bottom or dry bottom boilers, the operation temperature of the ESP, and the SO₃ conversion are important parameters.A further factor with influence on the raw and clean gas dust concentrations is the use of back-up fuel.Within these investigations, hard coal from Germany, Russia, Columbia, Poland, South Africa, and Australia were rated and the individual components and their influence on the precipitation is analyzed and presented.As a reference for the calculated dust resistivity and clean gas dust concentrations, investigations at Evonik power plants and different operational values were taken into account for validation.
