Abstract:

A study was made to optimize design for a small multistage flash evaporator for remote base operation using waste heat from a 100 kw, 4-cycle diesel generator, carrying continually varying electrical load. The design of such an evaporator is controlled by practical considerations to a greater extent than for a large stationary evaporator, where efficiency might be the most important factor. Since the cost of the unit increases with its coefficient of performance, the selection of design parameters depends upon the relationship between unit cost and the quantity of fresh water produced expressed as a function of available heat. It is shown that cost increases disproportionately with respect to coefficient of performance. However, justification for the additional expense is presented. The recommended design is an air-transportable 16-stage evaporator arranged in two adjacent 26-foot long sections connected in series. A discussion of some possible alternate designs is included.
