Unforeseen shutdowns in air pollution control systems (APC) can be the result of insufficient process knowledge and lack of understanding of individual plant requirements. Moreover, increased dust emission due to low-quality or inadequately-designed APC equipment not only impacts a cement plant’s environmental footprint but can also cause extensive wear on other equipment, such as filter fans, which increases overall maintenance and operational costs. By Ahsen Hussain, FLSmidth, Denmark.
Cement producers are under increasing legislative pressure to reduce dust emissions, a trend which highlights the need for high-quality APC equipment. In addition to installing new equipment, the options available are likely to involve rebuilding, retrofitting, converting or replacing existing equipment.
