The ultimate and proximate analysis of the fuel used for CFD modelling purposes is shown in Table 1 along with the fuel particle size distribution. The actual plant fires the fuel at a 99 % maximum continuous rating (MCR) with an excess air ratio of %.As the plant turns down from full load the excess ratio is increased to ensure sufficient air and fuel mixing in the furnace.

Reheating furnace for steel rolling mill line is a device (an industrial furnace) that heats a material or a workpiece (generally a metal) to rolling forging temperature in the metallurgical industry.. Structure and composition. According to the distribution of furnace temperature, the furnace is divided into preheating section, heating section and heating section along the length direction.
The scopes of modeling reheating furnaces can be divided into the following categories: furnace combustion modeling, heat transfer modeling including the slab heating process and the skid mark ...
Highcalcium bituminous coal has the advantages on combustibility, but its ash melting point is low, and it is easy to slag in blast furnace injection process. In order to explore the ash melting slag formation mechanism of highcalcium bituminous coal, the mineral evolution of ash in the combustion process of highcalcium bituminous coal and the influence of ash components on the liquid ...
For a reheating furnace, an analysis of thermal efficiency depends on precise investigations of the combustion and flow characteristics inside a furnace. Especially, the flow field of the hot gas has significant influence on heating slabs. The slabs are heated up to the temperature over 1500 K, and then they are transported to the rolling mill.
Pulverized coal injection (PCI) is generally used in modern blast furnace (BFs) ironmaking to reduce coke consumption by burning cheaper coal. This paper presents a numerical study on the effects of PCI on the inner states and overall performance of a 5000m 3 industrial BF. This is based on a recently developed integrated BF model that ...

Energy consumption in small and medium sized rerolling mills takes place in two forms namely (i) electrical energy, and (ii) fuel or heat energy. Electrical energy is used directly in main rolling process for shaping of hot billets into rolled product (rolling mill, and shears etc.), in reheating furnace (coal pulverizer, blower, and pusher ...
In most of the SRRM units, a 4inch pipe is used as a burner for pulverized coal. This 4inch pipe is inserted into the front and side walls of the reheating furnace. Only primary air in ambient temperature is used for combustion in such conventional burners and the airfuel ratio is neither monitored nor controlled.
The injection of pulverized coal was introduced at blast furnace 9 in December 2015. In November 2016, the pulverizedcoal consumption reached kg/t, with coke consumption of kg/t of hot metal. Technical constraints have prevented higher levels. Since both technologies are in use at blast furnace 9, various comparisons are possible.
