Stove and Blast Furnace Valve Technology
Paul Wurth’s advantage in carrying out large-scale projects is that the latest technologies and re-quested services for the construction and mod-ernisation of complete blast furnace plants are all found under the one roof.
Paul Wurth has a tradition of leadership in blast furnace engineering. Practical designs, systems and equipment have been the product of a dedi-cated and experienced team interacting with plant operators.
The gas produced in the blast furnace is an im-portant energy source in the efficient operation of an integrated steel plant. The primary purpose of the gas cleaning system is to produce a clean gas that can be burned in the hot blast stoves, coke ovens, mills reheat furnaces and power stations.
The Paul Wurth Group has many years of success-ful hot blast system design experience. The layout of the hot blast stoves, hot blast mains and mixer assemblies is unique to each project. Adapting existing stoves to enlarged furnaces is an added complexity. Paul Wurth has proven its ability to tackle these challenges. The final design includes pressure compensation and the choice of appro-priate valving.
Paul Wurth supplies the complete collec-tion of valves for hot and cold blast control, chimney valves, crude gas bleeder valves, equalizing/relief valves, as well for the complete stove regulation, and cares for concept and detail engineering, manufac-turing, erection and commissioning of the complete hot stove plant.
