boiler noises

what would cause a gas boiler to make crackling/popping noises while heating-water temp is below 180-pressure is 15psi-if I throttle down the gas shut off valve it is a little quieter-system has been flushed and purged-don't know what the gas pressure is(0.5 psi by supplier?)

    what kind of bioler ?

    how is it piped ?

    how old is the boiler?

    could it be low flow/no flow/ scaled heat exchanger?

    that noise snap,crackle,popping is it boiling? YES, MUST GET IT FIXED ASAP BEFORE ITS TOO LATE.
