Abstract
A flame simulating apparatus to simulate flames emanating from a wood or fossil fuel burning fire. The flame simulating apparatus includes a light source, a light reflecting element, and a fire simulation screen. The light reflecting element produces a moving and generally random pattern of reflected light when light is cast upon it by the light source. The fire simulation screen has the image of a fire thereon and is positioned so that reflected light from the light reflecting element is cast upon its rear surface. The fire simulation screen includes at least one portion that is at least partially translucent such that light cast upon the partially translucent portion by the light reflecting element is diffused and at least partially passes through the translucent portion to present a moving flame image when viewed from a position in front of the fire simulation screen.
