Study on Selection of Dust Collectors for Large Capacity Thermal Power Units in High Altitude Areas

摘要

A dust collector is an important equipment in a thermal power plant, and reasonable selection of a dust collector is important for environmental protection in the power plant. Huaneng Xining Power Plant is located at an elevation of 2 360 m. Based on the characteristics of the high altitude area and their special requirements for dust collectors, the selection of dust collectors for the thermal power unit in the high altitude area was studied, and then two types of dust collectors (a rotary electrode electrostatic precipitator and electric-bag composite precipitator) for the thermal power unit were compared from the aspects of technological and economical feasibility. Finally, a proposal to select a suitable dust collector for the thermal power plant was put forward.
