1. Introduction. In the steel industry, reducing fuel consumption in high-temperature processes is an urgent issue for decreasing CO 2 emissions. Coke serves as the main reducing agent in the ironmaking process, and it is produced by carbonizing coal in a coke furnace under high-temperature conditions of more than 1000°C.

For the sake of reduction of reducing agent in blast furnace, the use of ferro coke containing metallic iron as a catalyst was proposed to control the thermal reserve zone temperature. To produce ferro coke, the vertical type of coke oven is used …

Generally speaking, refractory materials for coke ovens include silicon bricks, semi-silica bricks, clay bricks, high alumina bricks, thermal insulation refractory materials, refractory fiber products, refractory mud, etc. 1. Carbonization Chamber. Carbonization chamber is periodic work, the temperature of the furnace wall surface decreases to ...

A vertical furnace provided in its top peripheral wall with a gas intake port and operated with an upper furnace unit sealed by raw materials present inside the furnace above the gas intake port, which is equipped with: (i) a right circular steel cylinder provided in the sealed zone in the upper furnace unit for partitioning charged raw material deposition zones, and (ii) a raw material ...

The determination of CO 2 reactivity index and coke or biocoke strength after reaction with CO 2 was carried out according to ISO 18894:2018 using a vertical reduction furnace and a tumbler (Model TB 5000 of R.B. Automazione, Genoa, Italy). According to ISO 18894:2018, the values for CRI and CSR are calculated using Equations (2) and (3).

Buy these vertical furnaces here to maximize your outputs and that too in energy-efficient ways. Alibaba.com offers multiple variations of vertical furnaces in distinct sizes, shapes, colors, features ...

Furnace coke is gray in color and is a hard, porous fuel that has a high carbon content. This material is made by heating coal or oil without the presence of air, which creates a unique destructive distillation process. Furnace coke is actually quite an important industrial product that is often used for iron ore smelting, fuel for stoves, and ...

After about 60 minutes, the coal will have coked, whereupon the gates 14 are opened to drop the columns of hot coke into the shaft furnace 6, as previously described. Residual gases issuing from the hot coke in shaft furnace 6 are exhausted via vents …

Coke derived from coal is generally grey, hard and porous. Coke, also known as low ash metallurgical coke (LAMC), is used in blast furnace for the production of iron. Coke acts both as reducing agent as well as a source of fuel …

The main purpose of high temperature carbonization is the production of metallurgical coke for use in blast furnace (BF) and foundry. Some coke is used for the production of calcium carbide (CaC2) and electrode carbons. More than …

The ovens are heated by burning product gas in flues between each oven. Coking takes about 12–20 hours for blast furnace coke. (Gray et al., 1987, 1988; Nishioka and Yoshida, 1983). The coke-making industry is dealt with in terms of coke as the primary product. Coke is fuel and a reductant in the blast furnace.

The coke produced is suitable for use in blast furnaces which turn the ore into pig iron, as well as for use in other kinds of furnaces used in making steel. Though not all the pig iron thus produced is turned into steel, some of it being …
