摘要： A compound spin vane (CSV) for use in an air passage of a fossil fuel-fired burner. In one embodiment, the CSV is a multi-piece construction of platelike outer and inner vane elements connected to an intermediate platelike rail element. In another embodiment, the CSV includes at least two and possibly three vane portions, rigidly interconnected in spaced lateral relationship with respect to each other. If desired, the vane portions may be simple, curved planar surfaces, and may be arranged with trailing edges arranged at angles with respect to each other. The invention may be employed as a replacement for flat spin vanes found in secondary air passages of known single and dual register burners. When used in such manner in a single register burner, the invention changes secondary air flow characteristics so as to mimic those commonly found in a dual register burner.

摘要： An economizer arrangement particularly suitable for new or retrofit application to existing steam generators provides a water cooled stringer support tube system which can accommodate firing a wide range of fuels with varying characteristics in the steam generator. The economizer arrangement according to the present invention is particularly suited for retrofit applications to large supercritical steam generators. The use of water cooled stringer tube supports allows for higher flue gas temperatures in comparison to conventional non-cooled mechanical economizer supports. These features are provided in a design which fits within the existing economizer envelope of the steam generator.
