How to achieve a stylized burning (Wireframe) effect?
Create a Cube or use default object and apply a Wireframe modifier.
with the cube selected go to the Physics properties panel and turn on Smoke. Set the flow type to Flame and Flow Source to Mesh (...

Can fire be made stationary?
As long as you don't need the smoke to start animating again after it has stopped you can set the start and end frame for the bake to before the set animation frames start.
Above I have set the start ...

Cycles Flame in Smoke Simulation not Rendering
It looks that you've used Quick Smoke. Though its material setup is ready to add the fire, it hasn't the shaders to it.
So you only have to add some nodes to that Input: mainly an Emission connected ...

How to get smoke to pour out object holes?
It looks like the resolution you are using for the smoke domain is too coarse. This makes the size of a smoke voxel possibly comparable or bigger than the apertures, preventing the smoke to "see" that ...

Is it possible to guide a smoke simulation along a curve?
Yes, this is possible - you can use a Force forcefield set to act along a curve and set to a negative strength to draw the smoke to the curve as in the following example :
However, this isn't ...

What's the difference between turning up the resolution vs. using smoke high resolution in the Blender smoke simulator?
Turning up the base resolution increases the actual number of voxels used to calculate the sim. The high-res divisions are a separate, secondary effect. They are applied after the sim itself ...

Why does fire take so long to render?
Because fire is a volume, and volume rendering is slow. First of all, the baking you did doesn't help with rendering, it just caches the simulation itself. Anyway, the problem with rendering volumes ...

Fire Doesn't Rise Up and It looks Fake
The fire doesn't rise because your objects are much bigger than in the video (~7 m sphere vs ~1.3 m sphere). Compare the size of the turbulence force field (2 m) with your sphere's size.
