| 摘要 |
The disclosure relates to simulated flame effect fires which include an apertured bed, such as a simulated fuel bed, a vapour generator (e.g. an ultrasonic transducer 458). In various embodiments the transducer may be in contact with fluid at a hole 456 in a liquid container wall 452; the frequency of the transducer may be at least 1.7Mhz; the liquid may be regulating from a reservoir to the container to maintain a constant volume; a rising current of warmed air may carry the vapour through the apertured bed; a vapour distribution channel may allow a rising current of air through the chamber; an air current may flow through a liquid container headspace; and/or the transducer may be disposed higher than the apertured bed. Light sources can be provided below the fuel bed to provide localised illumination. |
