heat11 sends a boiler to the »Noor Ouarzazate« Solar Complex
Last week, heat 11 GmbH & Co. KG supplied a fired heater with impressive data:
length: 10,5 m
diameter: 4,0 m
weight: 40 tons
The boiler is used in the parabolic trough solar power plant »Noor II« in Morocco as so-called »night heater« or »anti-freeze heater«. That means the boiler heats the solar field and the entire HTF-loop in the night and during longer standstill times when the temperature in the solar field threatens to fall below the freezing point point of the heat carrier (+12 °C).
The boiler was designed as a maintenance-friendly bottom-fired construction which also reduces the otherwise necessary steel construction to a minimum (see illustrations).
Besides boiler, chimney, burner and dust collector (»sand-trap«), the heater plant comprises also the complete control system which is installed in an air-conditioned container.
The Noor Ouarzazate Solar Complex is being developed 10km north-east of the city of Ouarzazate (Morocco). Phase one of the project involved the construction of a 160MW concentrated solar power plant (CSP) named Noor I, while phase two involves the construction of the 200MW Noor II CSP plant and the 150MW Noor III CSP plant, and Phase Three will involve the construction of the Noor IV CSP plant.
Phase one construction works started in August 2013 and Noor I was officially commissioned in February 2016. Noor II and Noor III are scheduled to start commercial operations in 2017 and 2018, respectively.
The project is being developed on a build, own, operate and transfer (BOOT) basis by ACWA Power Quarzazate, a consortium of ACWA Power, the Moroccan Agency for Solar Energy (Masen), Aries and TSK.
The solar complex will be operated and maintained by a consortium led by NOMAC, a subsidiary of ACWA Power, and Masen.
