But in fact, they are a remarkably simple technology — albeit on a large scale — that is really no more mysterious than a fireplace or pottery kiln. They take iron ore, charcoal or later, coaland limestone to turn out iron for use by the community or for export and sale beyond the community. In order to understand the blast furnace, let's take a look at one built in Maryland in the s.

Get a Quote Blast Furnace Blast furnaces are used to produce iron. Iron was the material that gave rise to the Industrial Revolution.

Abraham Darby created the first blast furnaces fueled with coke instead of charcoal. Charcoal is created from burning trees and requires a lot of labor and resources. Coke is created from coal which is less labor intensive and saves community timber resources. The coke mixed with iron ore and limestone created a much stronger iron than could be made with charcoal.

Modern blast furnaces are made from refractory brick surrounded by steel. The hollow stacks receive raw iron ore, coke, and limestone through the opening at the top. Hot air is blown into the bottom of the stack.

The materials melt and combine to form liquid iron and slag which drains at the bottom. The combination of high heat with the chemical compounds found in each raw material cause chemical reactions to occur within the furnace.

These chemical reactions purify the iron ore and create iron. The chemical reactions and the temperatures they occur are listed below.As part of the OCC project, T system sprays water droplets to remove the chlorides by forcing the aqueous dew point.

CFD study had been conducted to achieve thorough understanding of the current design. BLAST FURNACE COOLING SYSTEM INTRODUCTION Blast furnace relining is very costly in terms of both investment and lost production time. The longer a furnace operates before requiring a complete relining, the lower the .

biggest heat load of a blast furnace is concentrated within the lower stave region of a blast furnace with intensified smelting. Cooling staves is one of the most important reasons that bring in major overhaul of a blast furnace.

Therefore, cooling stave life is a key parameter for the life of a blast furnace. Hatch completed a pilot installation in of a pair of finger coolers in a blast furnace cast iron stave and a comparison of predictive models to site monitored temperature data will be presented using a series of thermal finite element analyses.

The System of a Blast Furnace Blast furnaces seem alien, strange, and dangerous to us today. But in fact, they are a remarkably simple technology — albeit on a large scale — that is really no more mysterious than a fireplace or pottery kiln.

Some blast furnaces use a "double bell" system where two "bells" are used to control the entry of raw material into the blast furnace. The purpose of the two bells is to minimize the loss of hot gases in the blast furnace.
