Abstract
A method of disrupting vapor films formed in film boiling in boilers, in which method transient electrical discharges are effected either in the boiler liquid or in a body of liquid in acoustic communication with the boiler liquid. The electrical discharges are effected at one or more selected locations in the boiler to produce shock waves which act on surfaces of the boiler liquid space where vapor films are to be disrupted. By disrupting such vapor films there is enabled an improvement in the heat transfer rates per unit area across the interface between the fire space and the liquid space of a boiler. There are also disclosed various arrangements in boilers for generating these shock waves. Electrical discharges may be effected between a pair of electrodes mounted in the boiler or between an electrode and an adjacent wall of the boiler, and several mounting configurations for electrodes in boilers are described.
