Impact collector with direct and indirect impact surfaces

摘要

A separator array for a furnace has large scale collection elements which can be formed from water-cooled tube walls and permit walk-through inspection and repair. The collection elements have direct impact surfaces, indirect impact surfaces and stagnation retainer surfaces. The array uses fewer, but larger collection elements than known separator arrays to provide at least the same solids collection efficiency while permitting the use of lower cost materials and easier inspection and repair.
