I want to detect fires/flames, in realtime camera stream, is it possible to do this using HSV color space and apply mask and filters to appropriately detect contours in given HSV colorspace, so what could be the HSV range that can identify/detect fire/flames.

I don't think that fires/flames have any specificity in HSV. Hue of flames depends on burning material, (e.g. pure methane produces blue flame) Saturation might be high, sure Brightness is very high such as white objects and common light sources.

how about training HOG+SVM in order to detect flames, using sliding window?

You can combine Color based detection (i suggest using CIELab*) with contours (Edge) detection for better segmentation.

You may want to detect flame movement using background subtraction.
