Show Geneva Steel Pollution Control Unit Hoars Halfway Mark, Efficient Unit Work to build one of the most advanced air pollution control facilites of its kind at the powerhouse of U.S. Steel's Geneva Works is near the halfway mark this week and moving ahead on schedule, H.A. Huish, Geneva general superintendent, superinten-dent, reported today. The $9 million uint, called a bag house, is expected to achieve an efficiency of 99.6 percent in cleaning par ticulates from burning coal at the powerhouse of the integrated in-tegrated steel mill. On completion, the new installation in-stallation will enable Utah steelmakers to produce electric elec-tric power from low sulfur coal, instead of natural gas, and still meet existing environmental en-vironmental regulations for particulate emissions. Local U.S. Steel engineers also report the new facility will make a significant reducation in over-al emissions of particulates at Geneva and improve air quality around the plant. Since 1958 Geneva has burned natural gas in its powerhouse boilers to supplement sup-plement gaseous fuels, generated during steelmaking processes, such as coke oven gas and blast furnace gas, in producing electric power. But curtailments on natural gas in recent years have required the plant increasingly in-creasingly to depend on coal as a back-up fuel. Addition of the new bag house will relieve Geneva's dependence on natural . gas and improve the availability of this important resource for homes and schools, Mr. Huish said. In operation, the new facility will clean waste gases at the powerhouse in much the same way that a vacuum cleaner removes dust and lint from a carpet. But the new Geneva cleaner will operate on a scale that would stagge the average housewife. Located at the south end of the powerhouse, the modern unit will be as high as a six-story building and (Continued on page 6) Geneva Steel to Build Bag House (Continued from page 1) cover an area of 11,500 square feet. Inside, more than 6,600 cloth filters, or bags, each 20 feet long, will provide a total collection surface equal to some seven acres and clean nearly one million cubic feet per minute of waste gases from three steam boilers at the powerhouse. Three giant fans will draw the waste gases into a single collection main measuring 17 feet in diameter. This main will divide into two steel ducts, duc-ts, each more than 12 feet in diameter, which feed 23 separate cleaning compartments compar-tments inside the bag house. Each cleaning compartment compar-tment will be an independent unit which can be repaired or maintained without interrupting interrup-ting operations of other bag house facilities. Dust collected by filter bags in the cleaning units will go into a 50-foot high silo where it will be watered down by wetting devices before removal to a special storage area inside the Geneva plant property. The new bag house is the latest of many air pollution control improvements installed in-stalled at Geneva Works in a continuing program to reduce emissions from the plant, Mr. Huish pointed out. The Geneva bag house is scheduled for completion and |
