所述光源1和转筒2构成转动光源，光源1固定在光源支架11上，光源支架11左右二端分别固定在左固定支架12和右固定支架13上，左固定支架12由螺母14固定在支架轴24上，支架轴24由坚固螺母22固定在转筒支架23上。右固定支架13固定转轴27，转轴27通过联轴器28与电机26的轴连接，电机26由电机支架29支撑。
所述转筒支架23和电机支架29均固定到电壁炉上。
所述光源1由导线16连接到电源上，所述电机26由导线16连接到电源上。
所述转筒2为透明筒体，表面横向设置若干个聚光块，聚光块方向与转筒2轴线一致。
所述透明筒体左端通过左端盖21固定到支架轴24上，右端通过右端盖25固定到转轴27上。
所述电机26由导线连接到电源上。当电机26转动时，便可带动转筒2旋转。
所述聚光块既可以设置在筒体内表面，也可设置在筒体外表面，本实施例中聚光块设置在筒体外表面上。
由于筒体为一整体，因此可以一次成型，方便制成。
所述转筒2还可为仅是与聚光块20接触的部分为透明，其余为不透明。
所述聚光块与筒体2可为一体，可整体成型。
所述聚光块与筒体2也可分开制作，最后将聚光块20固定到筒体2上,见图3。
所述聚光块为凸透镜20，这样能更好地聚光，投射到火焰板上火焰更生动逼真。
所述凸透镜20的外形可以是矩形，也可为圆形、多边形的或者其它的形状。
所述凸透镜的透光面可以是单一的平面、球面、弧面、曲面或者其他类型，也包括这些类型面的组合。
所述凸透镜还可就主体的局部做一些切除或伸出的改变。
所述透明分离板4包括若干个相互连接的纵向聚光块41，本实施例聚光块为凸透镜41，凸透镜41与转筒2上的凸透镜20垂直，这样，光源1发出的光线通过滚筒2的与凸透镜41相对面的凸透镜20在转筒的圆周方向上发生第一次分离，最终形成每一条凸镜对应的光带42，见图6；光带42再穿过透明分离板4的凸透镜41进行二次聚光，这样，可将进入透明分离板4前的光带42（见图6）转换成亮度更高、轮廓更清晰的光块52（见图8）而照射到火焰板3上。
所述火焰板3包括不反光区31和反光区32，不反光区31和反光区32交叉在一起，反光区32的形状象火焰，其置于透明分离板4前且与透明分离板4平行，这样，从透明分离板4射出的光线经火焰板3的反光区32反射后将火焰状光线投射到火焰投射屏5后在火焰投射屏5上形成模拟的火焰。
所述火焰投射屏5前还设置假燃烧材料如木材模拟体7,利用筒体中的光源1或另设光源可以使模拟体7产生暗红的发光，与木材燃烧时的形态相似。
使用时，开启光源1和电机26，电机26带动转筒2转动，光源1发出光线，光线通过转筒表面凸透镜20的一次分离产生光带，再通过透明分离板的二次分离产生光块照射到火焰板3的火焰状的反光区32上，最终反射到火焰投射屏5，产生火焰图象，并在木材模拟体7上方显示，因此，模拟出木材燃烧的景象。
使用所述火焰模拟装置的电壁炉结构见图1，在电壁炉上部设置热风装置50，加热周围环境。
热风装置50通常包括风机、发热体，发热体置于风机内，空气由发热体加热后经风机吹出。热风装置的加热机构也可由其他形式的装置代替。
热风装置也可设置在电壁炉的下部，通过电壁炉的空间合理布置。
电壁炉前部设置玻璃6,透过玻璃6便可看到火焰投射屏5，火焰模拟装置开启时便可看到火焰投射屏5产生的模拟火焰，使木材模拟体7的燃烧更逼真。
如图9所示，所述凸透镜20由规则的凸透镜变成了中间向内凹的形变后的凸透镜221，透明分离板4的纵向凸透镜41也由规则的凸透镜变成了中间向内凹的形变后的凸透镜43，其光线经凸透镜221、纵向凸透镜43后的光带见图10，仍能直到增加光亮度，火焰更逼真的效果。
