To be honest I might need more information, but I'll see if I can gather what you're trying to ask.
Some people experience a burning odor at random times (some say hair, others synthetic clothes, ect.). What they may actually be smelling is their olfactory sensor in that portion dying off. If you're smelling burning hair or it smells like something is burning all the time, I would suggest getting into an ENT physician ASAP as this is absolutely irreversible. They may be able to stop it from progressing, but will not be able to bring back the portion of smell that's missing once its gone.

Constantly smelling burnt food could be a sign of a medical condition like sinusitis, a sinus infection, or a brain tumor affecting your sense of smell. It is important to see a doctor for a proper diagnosis and treatment.
I would imagine that you would have to use your nose...
Because its burnt.
A nose that cannot smell would refer to an inanimate object or a non-living entity. One example could be a nose on a mannequin or a statue.
If you locked your wheels and slid, you burnt your tires and that will smell like burnt oil, since they ARE petroleum products.

Smell is an important part of our lives. Without it, we wouldn't be able to smell fires, for example. That would cause many areas to be burnt down.

Sense, smell, and nose are nouns. Your is a possessive pronoun, acting as an adjective.
