Research and application of new flue gas ultralow emission technology

Abstract

Abstract:

In order to meet increasingly stringent environmental protection requirements, reduce investment in engineering equipment and maintenance costs, taking the “developing large units and suppressing small ones” 2×660MW ultrasupercritical condensing heating units in Huadian International Shiliquan Power Plant as an example, the application of gas flue ultralow emission technology was studied. The units removed the wet separator that was of great waste water production, maintenance and power consumption, and adopted a fullload technical solution which was selective catalytic reduction (SCR) denitration+lowlow temperature electrostatic precipitator+ highefficiency desulfurization collaborative dust removal FGDPlus+media gasgas heater(MGGH). After more than 2year operation, the flue gas emission has always met the ultralow emission and strict national environmental protection requirements, which can provide a reference for the construction and ultralow emission retrofit of the sametype unit.
