Energy from hot gas discharge streams can be recovered by transfer directly to a coolant liquid in one of several available gas-liquid contacting devices. The design of the device is central to the theme of this paper, and experimental work has verified that the analogy between heat transfer and mass transfer can be used for design purposes. This enables the large amount of available mass transfer data for spray, packed, and tray columns to be used for heat transfer calculations. Recommended methods for designing the several types of gas-liquid contacting device are summarized.

The coupled interaction of cold liquid sprays and a hot gas stream is analyzed. The effect of liquid droplets introduced into a hot gas stream flowing in channels of constant and of varying areas is investigated as a rapid cooling process for a hot gas discharge. The effects of spray distribution, duct geometry, and wall friction are examined. Variations of gas and liquid spray properties such as gas temperature and velocity, droplets velocity, temperature, and distribution are presented as a function of distance along the duct in the direction of flow. The effectiveness of this rapid cooling process for a hot gas flow is assessed.

Boundary Reaction

The Ni4Mo alloy has a short-range ordered fee structure (α) above 868°C, but transforms below this temperature to an ordered bet structure (β) by rearrangement of atoms on the fee lattice. The disordered α, retained by rapid cooling, can be ordered by appropriate aging below 868°C. Initially, very fine β domains in six different but crystallographically related variants form and grow in size on further aging. However, in the temperature range 600-775°C, a coarsening reaction begins at the former α grain boundaries and the alloy also coarsens by this mechanism. The purpose of this paper is to report on TEM observations showing the characteristics of this grain boundary reaction.
