Introduction

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals.

In a blast furnace, fuel (coke), ores, and flux (limestone) are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with oxygen enrichment) is blown into the lower section of the furnace through a series of pipes, so that the chemical reactions take place throughout the furnace as the material falls downward. The end products are usually molten metal and slag phases tapped from the bottom, and waste gases (flue gas) exiting from the top of the furnace. The downward flow of the ore along with the flux in contact with an upflow of hot, carbon monoxide-rich combustion gases is a countercurrent exchange and chemical reaction process.

Roots blower is used as air supply for blast furnace.roots blower can supply air to the necessary pressure required for the furnace. roots blower is the first equipment in the air blast system. It is located in the blower house and is meant for providing cold air blast to the hot blast stoves at the desired constant flow volume and pressure. Hence surge protection control is a very important control for a blast furnace air blower. Generally two numbers of air blowers are provided for a blast furnace. It draws the volume of air from the atmosphere and compresses it to the needed pressure and blows it into cold blast main. The compressed air is usually at 150 deg C to 250 deg C, which is the temperature resulting from the heat of compression at the air blower. The air blowers are either steam turbine driven or electric motor driven. The air blower is required to be operated to meet the air flow conditions which in turn are determined by the operating condition of the blast furnace. Also they need to have a very high level of reliability since the performance of the blast furnace depends a lot on the performance of the blower.
