JIN Lipeng1, WANG Yong2, SONG Yubao1, et al. Effect of viscous fly ash on the SCR system design[J]. Thermal power generation, 2013, 42(8): 124-127.DOI:
Catalyst abrasion and blockage by fly ash is the main reason for performance worsening of the SCR device.Two SCR flue gas denitrification process design cases were compared to investigate the significance of such parameters as flue gas flow
fly ash characteristics during SCR device design.It is pointed out that basic parameters like flue gas flow
temperature
fly ash
ash granular distribution and mineral composition should be obtained at first
and it is important to optimize the design of ash wiping
anti-deposition and anti-abrasion according to the fly ash characteristics.
