rotary kiln for petroleum coke calcining

In the calcination of petroleum coke in a rotary kiln, procedure wherein air is controllably supplied internally of the kiln to burn the removed volatiles, as by selection or adjustment of the amount of such air and of the speed of coke travel down the kiln, so that all or nearly all of the heat for calcining the coke is provided by such combustion, and so that a suitably high temperature is

    Petroleum coke calcining rotary kiln uses the volatile component emitted in the roast process of the petroleum coke to calcining sufficiently. It can reach the need temperature for roasting the petroleum coke and needs little additional fuel. 2. It can realize to roast 12 tons to 15 tons petroleum coke per set, and decreases the carbon burning

    Petroleum coke is usually calcined in a gas-fired rotary kiln or rotary hearth at high temperatures, around 1200 to 1450 C, to remove moisture, drive off volatile matters, increase the density of the coke, increase physical strength, and electrical conductivity of the material. Rotary kilns have

    The invention relates to a calcining process of petroleum cokes and equipment, in particular to a calcining process of petroleum cokes by using a large rotary kiln. The process adopts the unique process of first grinding and then sieving the petroleum cokes and the technology of quantitatively feeding materials to the rotary kiln. A cooler is used for cooling the cokes calcined at high

    Typical temperatures for a rotary coke calcining kiln are between 2200 F (1200 C) and 2400 F (1315 C). Alumina-silica refractories in the 40% to 70% Al2O3 range are appropriate for these normal operating temperatures. Petroleum coke calcining operators prefer single-layer brick linings using rotary kiln block (RKB’s)

    The typical calcining plant consists of one or more rotary kilns, a rotary cooler, settling chamber and stack. Typically, petroleum coke is fed into the backend of the rotary kiln. Rotary kilns are lined with refractory monolithics or brick. As the coke travels down the rotary kiln, it passes through numerous sections, some containing

    Dec 20, 2014 The first rotary kiln for calcining GPC was used at Great Lakes Carbon in 1935,2 although rotary kilns had been used in the cement industry prior to that. Rotary kilns for CPC production are steel shells lined with high-temperature refractory brick; kilns can measure 30–85 m in length and 2.4–4.4 m in diameter
