A circulating water plant or circulating water system is an arrangement of flow of water in fossil-fuel power station, chemical plants and in oil refineries.
 The system is required because various industrial process plants uses heat exchanger, and also for active fire protection measures.
 In chemical plants, for example in caustic soda production, water is needed in bulk quantity for preparation of brine.
 The circulating water system in any plant consists of a circulator pump, which develops an appropriate hydraulic head, and pipelines to circulate the water in the entire plant.
Bruckenthalia is a genus of plants consisting of only one species, Bruckenthalia spiculifolia (spike heath) an evergreen shrub native to southeastern Europe and Asia Minor.
 It is a dwarf and heath-like plant to 10 in high.
 Suitable for rock gardens and borders.
 Leaves are dark green.
 The flowers in terminal clusters of rose-pink, bell-shaped appear in early summer.
Nordjylland Power Station (Danish: "Nordjyllandsværket" ) is a coal-fired combined heat and power plant in Vodskov, 17 km north-east of Aalborg, Denmark.
 It is operated by Aalborg Kommune.
 The power plant consists of 3 coal turbines and a gas turbine.
 Of these units, one is shut down.
 The gas turbine has an output of 25 MW and entered service in 1977, while unit 2, which went also in 1977 has a maximum production capacity of electricity of 305 MW and heat of 42 MJ/s.
 Unit 3, which entered service in 1998, has a maximum production capacity of 411 MW and a maximum heat production capacity of 490 MJ/s.
 It uses a 170.1 m tall flue gas stack, while Units 1 and 2 and the gas turbine use 112.17 m tall stacks.
 Unit 3 was the first power plant in Denmark with a SNOX-system for exhaust cleaning.
Fothergilla malloryi is an extinct species of flowering plant in the family Hamamelidaceae known from fossil leaves found in the early Eocene Klondike Mountain Formation deposits of Northern Washington State.
 The "F. malloryi" leaves are the earliest appearance in the fossil record of a member of the witchalder genus "Fothergilla", which includes the living species "F. gardenii", and "F. major", both of which are native to the southeastern United States.
 The genus also includes three or four other fossil species with two Asian Miocene species, "F. viburnifolia" from China, "F. ryozenensis" from Japan along with one Miocene North American species, "F. praeolata" of Oregon. "
Fothergilla durhamensis" described from Eocene sediments in King County, Washington is considered dubious in placement.
Fothergilla major (large witch alder, mountain witch alder) is a species of flowering plant in the genus Fothergilla, family Hamamelidaceae, that is native to woodland and swamps in the Allegheny Mountains of southeastern United States.
 It is a deciduous shrub growing to 2.5 m with fragrant white bottlebrush flowers appearing along with, or before, the glossy leaves.
 The leaves often turn brilliant shades of red and orange in autumn.
Fothergilla gardenii, also known by the common names Witch Alder, dwarf fothergilla, American wych hazel, and dwarf witchalder is a deciduous shrub in the Hamamelidaceae family.
 It is one of two species in the genus "Fothergilla."
The Lon D. Wright Power Plant is a 130 MW (megawatt) coal-fired power plant owned and operated by the City of Fremont Department of Utilities located in Fremont, Nebraska.
 The plant consists of 3 units labeled 6, 7, and 8 as a continuation of five units that were previously housed in the downtown facility.
Armoricaphyton is an extinct monospecific genus of vascular land plants described from Early Devonian (late Pragian-earliest Emsian) outcrops of the Chalonnes Formation in western France.
 The plant consists of small, leafless, longitudinally-ribbed axes that branch pseudomonopodially.
 Pairs of fusiform-shaped, twisted sporangia preserved as adpressions were found in association with the axes and may belong to this species.
 Permineralized specimens reveal the oldest documented wood or secondary xylem of any known fossil plant.
 The water-conducting tissues or tracheids consisted of extinct P-type cell walls.
 This type of cell wall consisted of scalariform bordered pits and perforated sheets that covered the openings (apertures) of the pits.
 "A. chateaupannense" is anatomically similar in some respects to other members of the Euphyllophytina such as "Psilophyton" and "Franhueberia".
 "Franhueberia gerriennei" is also one of the earliest land plants described from the Early Devonian (late Emsian) that was known to have wood.
 Given the differences between "Armoricaphyton" and these other genera and a lack of a complete understanding of the whole plant, "Armoricaphyton" is currently classified as Euphyllophytina "incertae sedis".
The Snoqualmie Falls Hydroelectric Plant is located just north of Snoqualmie in King County, Washington state, US.
 It is situated about 22 mi east of Seattle.
 Located just below the Snoqualmie Falls, the power plant consists of two power houses, Plant 1 and Plant 2.
 Plant 1 was completed in 1899 and is located underground.
 It is the first completely underground hydroelectric power plant ever built in the world.
 Plant 2 was built in 1910 and is located along the right bank of the Snoqualmie River.
 Both plants receive water from a small reservoir created by a weir atop the falls.
 Plant 1 has an installed capacity of 13.7 MW and Plant 2 a capacity of 40.2 MW for a total installed capacity of 53.9 MW, enough to power 40,000 homes.
Fothergilla (witch alder) is a genus of two or three species of flowering plants in the family Hamamelidaceae, native to woodland and swamps of the southeastern United States.

Question: Which genus of plant consists of more species, Bruckenthalia or Fothergilla?
Answer: Fothergilla
