Switching from China to India, the ten gasification reactors at the Reliance refineries at Jamnagar are designed to run on petcoke and for flexibility can also operate on a mixture of 35% coal and 65% petcoke. They are fed by five of the world's largest ASUs, each rated at a staggering 5250 tpd of oxygen.
High grade petcoke which is low in sulphur and heavy metals can be used to make electrodes for the steel and aluminum industry. But the majority of petcoke manufactured globally, approximately 7580%, is of a much lower grade, containing higher levels of sulphur and heavy metals and is used solely as fuel. The majority of petcoke produced in ...
When ACC decided to replace coal with petcoke as the main fuel for its kilns at the Gagal works, the vertical Emills required a high power input as they ran for extended periods. To reduce grinding time and hence save power expenditure, the cement producer called upon Walchandnagar Industries Ltd to design, engineer, manufacture, supply and ...
Vertical coal mills are used for grinding bituminous coal, anthracite and petcoke for the burning systems in clinker burning and power generation according to the type and quantity of additives. Note: Raw coal size 40～50mm, feed moisture ≤15%, final product moisture ≤%, final product finenessR80μm=10%～12% (bituminous coal), R80μm=1 ...
Producer gas obtained during gasification mainly comprises CO, H 2, CH 4, N 2, and CO 2 with traces of tar, NH 3, H 2 S, and HCl. Producer gas heat value varies from 4 to 7 MJ/Nm 3 with a yield of 34 Nm 3 /kg RDF with air as a gasification agent. However, the heat value increases considerably up to 1228 MJ/Nm 3 with O 2 as the gasifying agent [8].Some of the major advantages of RDF ...
Grinding of cement raw material material separation in cyclones. The cement raw material mixtures are ground, dried, and classified in the Pfeiffer vertical roller mill. For drying the material, hot gases are directed into the mill. Product fineness can be adjusted within a wide range ( to mm).
Plant Capacity. Bihar Cement Plant, A Unit of Shree Cement proposing expansion of Clinker. Grinding Unit from MillionTPA to Million TPA Cement (OPC, PPC, PSC SSC) along with installation of 20 MW Captive Power Plant, at Plot No. NS 24, NS 29 NS.
The cement industry is a high energy consumption activity. The rising cost of oil, natural gas and coal has increased the interest in using alternative fuels. There are a large variety of fuels that can be fired in cement kilns, such as petroleum coke, bituminous coal, sub bituminous coal, tires, etc. Pet coke used as
2 Design features of MPS mills for coal grinding. Depending on the material to be ground, throughput rates of 5200 t/h can be achieved in a fineness range between 1% mm and 25% mm. Thus, the MPS coal grinding mill device for fresh material is arranged in this area where the fresh feed is also mixed with the grits rejected from ...
Next, in November 2014, Titan Cement ordered a Gebr. Pfeiffer SE type MPS 2800 BK vertical roller mill for coal grinding, to be set up at line 1 at its Beni Suef plant. In January 2015, Suez Cement, Italcementi's Egyptian arm, said that it would spend US84m during the year to convert its Helwan and Tourah 2 cement plants to use coal.
This doesn't include the impact of higher transportation costs. Second, imposition of a clean environment cess of Rs 800 per tonne on pet coke usage would result in a nearly 10 per cent increase in per unit fuel costs, the report says. However, the price factor today is tilting in favour of the cement companies, considering the numbers involved.
Grinding of clinker consumes power in the range of kWh/ton of clinker produced. These and other pyroprocessing parameters make cement production costly. The pyroprocessing process in kilns and the grinding technologies therefore have to be optimized for best processing. This paper discusses the cement manufacturing and grinding processes.
