I don't know about decks, yet my home provides 2x10 joists over a span of about that long without any type of troubles.

Yes, two 2x10"s covering 13"-6" will assistance 2,200 lbs. Grade of timber can be No. 2 & much better of typical framing wood, choose Hem.-Fir...it need not be Doug. Fir-Larch. In fact, each 2x10 will assistance 1,200 lbs.
To be clear, spans are measured as "clear spans". That is to say, from challenge of support to challenge of assistance. Also, if your BBQ is situated in the middle of the expectancy so that world deserve to stand roughly the BBQ, then tbelow will be a secondary "Live Load" acting on the joists. This assumes the BBQ exhas a tendency from assistance to assistance.
By the means, the code doesn"t require blocking till you use 2x12"s. However, for this "concentrated" fill, I"d usage blocking. (Yes, I understand, technically, it"s not a focused pack, bereason it exoften tends from assistance to support. However, it might be thought about "concentrated" bereason it"s relaxing on just 2 joist, not over multi-joists, prefer in a big area (room).)
If the joists remainder on a beam, then secure the joists to the beam through a clip. If they "hang" on a beam, make sure the hangers are rated for the fill, because you"re approaching the joists maximum fill. The joists require a minimum of 1 1/2" bearing at each end.
You didn"t ask, yet don"t forget to install seismic deck straps (or rods) at around 20" oc. This is brand-new to the 2014 code for all decks.
Re: your question around doubling joists...will that double the allowable supporting fill...yes, that is how it functions.
By the way, you recommendation a 10" room. Shouldn"t that be 13"-6" area (span), or are you referring to the distance in the various other direction. However, to me, that doesn"t seem appropriate bereason it does not add load to the 2x10 joists supporting the BBQ, right?
