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.

Complicated Process

The evaporation rate of a liquid spray in a turbulent gas stream is of interest in connection with direct contact heat transfer and combustion equipment. Any fundamental approach to this problem has usually dealt with single drops evaporating in an “infinite” atmosphere. The evaporation of sprays from actual atomisers is obviously a more complicated process and few attempts have been made to find in how far single drop data may be applied, or to measure the evaporation from a whole spray.The main difficulties lie in devising a satisfactory method of measuring the evaporation rate. Selden and Spencer, injected the liquid into a bomb filled with hot gas under pressure and measured the decrease in pressure with time on a special indicator.

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.
