A star has a large mass, and when the gases of the star undergo gravity compression, they heat up enough to initiate fusion. Firstly by combining four hydrogen to make one helium, thus releasing some spare energy. So the star heats up further, and fusion of other elements becomes possible.
Stars are not powered by combustion; they are powered by nuclear fusion, which is a fundamentally different and far more energetic process.
Nuclear Fusion
Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.

Yes, stars are fusion reactors.

Nuclear fusion is the process that powers stars, such as our sun.
Initially it is hydrogen. When that is spent, stars move to fusion of helium. There are also other fusion processes which take place: which process depends on the stars' mass.
