PacifiCorp adding gypsum conveyor at Huntington coal plant

The Utah Department of Environmental Quality began taking comment as of Dec. 18 on a tentative air permit revision that PacifiCorp Energy needs for the addition of a new gypsum load-out conveyor at its coal-fired Huntington power plant.

The load-out conveyor will serve a Unit 1 scrubber upgrade and Unit 2 scrubber installation previously permitted at the DEQ. Gypsum is a scrubber byproduct.

Huntington has two nominal 480 MW utility boilers.

  • Unit 1 is a dry bottom, tangentially-fired utility boiler fired on subbituminous and bituminous coal using fuel oil during startup and flame stabilization. It is equipped with a fabric filter baghouse, low NOx burners with overfire air system and a flue gas desulfurization (FGD) scrubber.
  • Unit 2 is a dry bottom tangentially-fired utility boiler fired on subbituminous and bituminous coal using fuel oil during startup and flame stabilization. It is equipped with a fabric filter baghouse, low-NOx burners with overfire air system and an FGD.
