Reinstalling the Gas Supply Components at the Bottom of a Blast Furnace
The process of restoring the blast furnace to peak efficiency begins with a proper reinstallation of the gas supply components located at the bottom of the furnace. This paper will focus on providing a description of the tools and techniques needed to properly install the gas supply components so that the furnace operates as it should.
The gas supply components located at the bottom of a blast furnace consist of a gas inlet, a blast pipe, an extraction valve, and a regulator valve. Each of these components must be reinstalled correctly in order for the furnace to produce the required amount of heat for efficient melting of the iron ore.
One of the most important steps in the reinstallation process is to ensure the proper positioning of the gas inlet. The gas inlet should be connected to the gas line using appropriate fittings and should be positioned at the optimal distance from both the ash dump and the air blast pipe. Care must also be taken to ensure that the gas line is able to provide the required flow to the gas inlet.
The second component of the gas supply system, the blast pipe, must be connected to the gas inlet and should be positioned at the optimal distance from the furnace walls. The orientation of the blast pipe should also be adjusted so that the pressure and temperature of the gas flow at the furnace walls is sufficient to reach the desired melting temperature.
The third component of the gas supply system, the extraction valve, must be installed at the optimal position within the gas line. This component is responsible for controlling the flow of gas from the gas inlet to the blast pipe and must be adjusted according to the required pressure and temperature profile.
Finally, the fourth component of the gas supply system, the regulator valve, must be correctly adjusted to ensure that the pressure and temperature of the gas at the furnace walls is within the required range for peak furnace performance. This component is typically set at the maximum pressure for a given blast furnace and the temperature should be adjusted according to the desired fuel-to-ore ratio.
Once the gas supply components have been installed or re-installed, it is important to test the furnace in order to ensure that it is operating at peak efficiency. This will involve running the furnace with a range of fuel-to-ore ratios and monitoring the pressure and temperature at the furnace walls. If the furnace is not achieving the required temperatures or pressures, the appropriate parts of the gas supply system should be adjusted or replaced.
By following the proper installation process, the gas supply components of a blast furnace can be reinstalled and adjusted to ensure that the furnace operates at peak efficiency. This involves ensuring the correct positioning of the gas inlet, the blast pipe, the extraction valve, and the regulator valve, as well as making adjustments to the flow rate and temperature of the furnace. Keeping the components of the gas supply system well maintained and properly adjusted will ensure optimal furnace performance and safety.
