I found it impossible to make an explosion from a VDB file. That is, the density works fine, but Blender ignores the temperature specified in the emission. I tried to change a lot of settings, such as emission scale, or a combination of different types of emission in materials. But I despaired, nothing helps. Here are screenshots of what I had. Explosion taken from OpenVDB Sample Section.

In most cases the fire from VDB is best rendered with Texture emission not with Blackbody emission. The emission nodes must be plugged into Emission input. The emission ramp input is for Volume Ramp Tex. If you want to use Blackbody increase Emission scale but the result may be strange.
