The rotary kiln is producing almost 3000 tonnes clinker per day, and so far the main fuel has been petcoke. ... meaning that only petcoke is used as fuel both in the burning zone and in the riser duct (primary and secondary fuel). The pre-heated air to the burning zone is varied between 430000 m 3 /h and 500000 m 3 /h (800°C, 1 bar ...
Simulation of Combustion and Thermal-flow Inside a Petroleum Coke Rotary Calcining Kiln . A Thesis Submitted to the Graduate Faculty of the University of New Orleans
with three kiln lines producing 1.85 million tpa of clinker. Kiln 3 is a preheater kiln producing 1650 tpd. The kiln uses solid fuel, with oil and gas as back up and warm up fuel. Akcansa Cimento was using a combination of imported and local coal with up to 30% petcoke, but was keen to use more petcoke since it is a cheaper fuel.
A. A Boateng, in Rotary Kilns (Second Edition), 2016. Abstract. Petroleum coke is a by-product of the coker process in the oil industry. In its raw form, it is also called "green coke" or green petroleum coke. Calcined petroleum coke is an important industrial commodity that links the oil and the metallurgical industries as it provides a source of carbon for various metallurgical ...
Function of a rotary kiln burner: • Mix fuel and combustion air to produce a stable flame and to release heat in a way adapted to process requirements. 8 Peers Conference 2019 – Rotary Kiln Burner Rotary Kiln Burner & Flame Theory Impulse (Momentum): • Force generated by the primary air and fuels discharge velocity at the burner tip.
The hot meal, i.e. calcined raw meal after the 5th stage cyclone, enters the rotary kiln and flows counter-currently to the hot flue gases that are produced by the kiln burner flame. The rotary kiln can be divided into three different zones, as specified in Figure 1. The material cold end is the inlet of hot meal into the rotary kiln.
FlexiFlame™ burners are customized to deliver thermal power up to 150 Gcal/h. They can use just one or multiple fuels, with variable mix, as: • Solid fuels: petcoke, anthracite, lignite, bituminous coal, charcoal, etc. • liquid fuels: light and heavy fuel oil, diesel oil, vegetable oils, etc. • …
ABC ® (Advance Burning Concept) is the Cimprogetti vertical single shaft kiln with counter current flow arrangement and is the latest in the evolution of compact design.. Thanks to its particular firing system, the ABC ® kiln can produce medium-high to low-reactivity lime with an optimal use of diverse limestone sizes and a variety of fuels.. The ABC ® kiln features a cylindrical steel ...
The aim is to develop a kiln burner with the capability to reach the maximum burner momentum at any flame shape, not only in one single point as with two primary air channel (or nozzle) burners. The burner momentum is the power available to the kiln operator to control the combustion process in the rotary kiln.

5-6 t/h more clinker production because of more stable kiln operation (3,5 – 4%) The kiln has been operated with high sulphur petcoke (7,5% sulphur content) without any major problems concerning either operation or clinker quality; Smooth and continuous coating results in longer brick lifetime; Better control of burner flame shape; Conclusion:
(a) A multi-fuel (gas/solid/biomass) lime kiln burner, (b) multi-fuel (gas/liquid/petcoke) pulp and paper burner (c) light weight aggregate kiln burner (courtesy KFS) Kilns are huge consumers of energy and are identified as a stationary source that emits more than 25 tons of nitrogen oxides (NOx) per year [4] due to the high flame temperatures ...
A TEC GRECO kiln burners are the most advanced technology for burners firing pulverized fuel developed for rotary kilns. While the Standard Kiln Burner has three shaping airflows, the FLEXIFLAME™ Rotary Kiln Burner operates with four airflows. The unique design of the burners with two tangential airflows to enfold the solid fuel injection flow - allows, throgh simple procedures, to …
Jun 15, 2018· The production of clinker takes place in a rotary dry process kiln. It was assumed that the dry process plant, producing 1,500,000 tons of clinker per year at a specific thermal rate of 850 kcal/kg and includes two rotary kiln/preheater lines, with a baseline fuel corresponding thermally to 30% coal and 70% petcoke at blower capacity. 2.6.
Coal utilisation in the cement and concrete industries . Jan 01, 2013 In terms of coal utilisation in the cement manufacturing process, its use as a fuel in rotary kilns is the main area of consideration 1536 Finish grinding and distribution After production in the kiln, clinker is stored on site in silos or clinker domes until needed for cement production
