Abstract:

With the deepening contradiction between energy and environment, the energy industry is transforming from traditional energy to clean energy. Therefore, more and more attention will be paid to high efficiency and low carbon natural gas distributed energy (NGDE). However the continuous improvement of environmental protection requirements will strongly promote the large-scale application flue gas denitriation in project. In this paper, the application possibility of selective catalytic reduction (SCR) denitriation is analyzed and studied, taking a building-type project in NGDE as the research object. Finally, the project has been successfully applied in a small MW NGDE system, and the efficiency of denitriation is over 95%, and the emission value of NO_x is 25.4 mg/m³, which meets the emission standard in Beijing. It provides a new solution for denitriation of NGDE projects.
