20-05-2021· Pulverised Coal Injection: the good, the bad, the ugly. Report summary. Operating in the shadow of other more prominent steel raw materials, pulverised coal injection (PCI) is a tried and true blast furnace technology, anchoring coke- and cost-reduction strategies for many global steel companies.
Pulverized Coal Injection (PCI) using the dense-flow method. The Küttner developed and perfected dense-flow method offers several advantages over a lower-density system. Higher injection rates are achieved with simultaneously lower coke rates, which can optimize the fuel costs of the blast furnace.
High rates of pulverized coal injection reduce the required amount of expensive metallurgical coke. ... Dilute Phase systems where amongst other features dilute phase is well known for its robustness with various types of coal and of course dense phase is known for achieving lower gas consumptions.

21-02-2018· INTRODUCTION Pulverized coal injection was developed in the 19th century, but was not implemented industrially until the 1970s. Even PCI technology was available at that time in several countries but due to the economics and ease of the process oil and natural gas injection became more popular. Rises in the cost of Coke due to increased global demand and thus more competition for the …
Pulverized coal injection or 'PCI' technology is just one area where Claudius Peters brings together several of its 'Techniks' to offer a comprehensive turnkey system. Combining unparalleled knowledge of grinding and pneumatic conveying over long distances and silo storage expertise with precise measuring and coal dosing technology ...

Pulverised Coal Injection (PCI) PCI for Blast Furnace method is becoming very popular globally. It is a process that involves injecting large volumes of fine coal particles into the raceway of a blast furnace (BF). This provides not only a supplemental carbon source but also speeds up the production of liquid iron besides reducing the need for ...
04-10-2018· Coal explosibility affects the safety during the injection of coal in the BF. Reactivity – The reactivity of coal refers to reacting ability of coal with carbon dioxide (CO2) or water vapour (H2O) under certain conditions. After pulverized coal injection in the BFe, part of the unburned coal (char) reacts with CO2 while ascending with the gas.
Pulverized Coal Injection (PCI) System A simple and low-cost PCI system NIPPON STEEL ENGINEERING CO., LTD.'s PCI system is superior in terms of (1) supply record, (2) function (circumferential balance of the injected pulverized coal), and (3) cost.
Pulverized Coal Injection (PCI) adalah proses penyemprotan serbuk batubara ke dalam ruang bakar boiler yang menggunakan sistem chain grate dan fixed grate. Sebagaimana kita ketahui bahwa boiler dengan sistem chain grate dan fixed grate membutuhkan waktu lama ( bisa sampai 2 jam) untuk menaikkan tekanan (pressure) dan menaikkan produksi uap (steam)

Pulverised Coal injection into the blast furnace provides the operator with an option of reducing consumption of the more expensive variant of carbon – metallurgical coke. But metallurgical coke has other useful mechanical duties to perform in the furnace …
The capacity of our system is 200 kg/t-pig of injected pulverized coal. (2) Improved RAR by means of a high level of accuracy in the circumferential balance of injected pulverized coal Air or N2 is added to each pulverized coal support pipe to enable the achievement of uniformity of the ever-changing pulverized coal quantities
Injection of auxiliary reducing agents as oil, natural gas and mainly pulverised coal contributed in the past three decades largely to the drop in coke rate. 12.9 . Reducing agent consumption in German blast furnaces ( Peters and Schmoele, 2012 ).
pulverized coal ratio to a 130 kg/t level, (Fig. 2). Table 1 shows the various types of injection for the blast furnace pulverized coal equipment. Table 2 shows the highest level attained in Japan for the typical operational index of blast furnaces utilizing pulverized coal injection technology.
