Unfortunately, in the application shown in Figure 1, because of limitations in the vertical height available between the overflow weir in the side of the calciner
and the lime cooler the solids transfer system as designed could not operate as a stable L-valve because (a) the vertical leg was shorter than the horizontal leg, (b) the aeration point was not positioned above the centre line of the horizontal pipe (c) the discharge end of the horizontal leg was higher than the level of the fluidized bed in the cooler and (d) the valve diameter (200 mm) was so large that the minimum controllable solids flow rate was almost seven times the design production rate.
In May 1999, the first preliminary test burns were conducted with dry wood chips and shavings fed directly into the calciner
at the plant.
Filtered bicarbonate is heated to 175[degrees]C in a sealed rotary calciner
, from which rich Carbondioxide gases are led to the second Carbonating tower.
To support the activated carbon thermal process operation, the facility features equipment acquired at a cost of over $14 million (exclusive of shipping and installation costs), including a 40-foot Bartlett-Snow Rotary Calciner
and a 2,000 gallon Alstom Power Char Converter Reactor.
Alba), with an aim to further strengthen its safety culture, announced the launch of the HSE Week by Alba Calciner
& Marine from 8 to 12 December, 2013.
Environmental Protection Agency (EPA) is enforcing air quality regulations for equipment that thermally processes industrial sand and meets the regulatory definition of a dryer or calciner
Dubai Aluminium Company (Dubal) has bought a 20 per cent stake in a calciner
development project in China, said Zawya Dow Jones report.
Summary: Dubai Aluminium (Dubal), the entirely state-owned enterprise whose Jebel Ali operation ranks as the world's largest single-site primary aluminium smelter using pre-bake anode technology, has expanded its interest in the upstream (raw materials) sector by purchasing a 20 per cent stake in a calciner
development project as part of a joint venture with Sinoway Carbon Energy Holdings, Hong Kong, for an undisclosed sum.
(front end of the plant) feed rate is currently operating at 15 tonnes/hour compared with a design instantaneous rate of 18 tonnes/hour, or 83% of instantaneous design capacity.
Mr Schmitt visited the marine facilities, calciner
plant, power plant, potlines, casthouses, carbon plant, R&D, engineering and several other departments.
In Minerals for Refractories, to support demand growth on some markets, particularly due to substitution to other minerals, a refractory clay calciner
was built in the Andersonville (Georgia, United States) plant and the andalusite production capacity extension in Yilong (China), a company acquired in 2007, is in progress.
Emerson's Smart Wireless installation on the refinery's calciner
unit monitors bearing and calciner
coke temperatures to help prevent fan and conveyor failure.
