Energy savings through improvements in fume control methods for melting shop extraction systems

Obiettivo

The objective of this project is to reduce the costs of electrical energy used by steelplant fume extraction systems whilst maintaining adequate fume collections by matching the extraction rate to the level of fume present and by careful control of waste gas volumes and pressures.
A Swindon Laboratories obscuration meter has been installed at the Templeborough Electric Melting Shop (TEMS) of United Engineering Steels and a control system developed to provide satisfactory fume collection from the roof hoods at reduced cost.

This system has been matched with a United Engineering Steels development of a variable speed control installation to one of the four operable fans serving the fume extraction plant.

Although the variable speed control installation has not been totally reliable in operation and not reached its full potential, a workable control system has been developed and the combined scheme has been shown to be capable of providing savings of 75 000 pounds sterling/annum.

A mathematical model has been developed using computer techniques, and checks using practical values obtained from the TEMS plant installation have proved its reliability.
Extracting and cleaning large volumes of fume laden air and waste gases from furnaces and hoods in steelmaking plants imposes high added costs on the steel produced. A recent study has been concluded showing that the system resistance imposed by large bag filters can be substantially reduced by changes in filter material and in filter cleaning operations.

The reduction of total volume waste gas is the second means by which power consumption can be reduced. Whilst the 'snuff box' is the desired approach to fume control on new furnaces (allowing for the possibility of the system being detrimental to the rate of working), there are still many furnaces working where the installation cost or layout prohibits their use.

Some ECSC supported research has already been carried out considering waste gas volume control. The studies proposed here are intended to build on results of these two projects and also make use of BSC experience in the control of fume extraction systems.
