1. A chemical looping system comprising:
a fluidized-bed combustor reactor comprising a windbox, a heat exchange surface, and an oxidant distribution grid;
a particle;
a particle separator;
a riser;
a particle receiver; and
a moving-bed reactor;
wherein the fluidized-bed combustor reactor oxidizes the particle, creates a carrier gas, and the riser transports the oxidized particle and the carrier gas to the particle separator; and
wherein the particle receiver receives the oxidized particle from the particle separator and the moving-bed reduces the oxidized particle in the presence of a carbon-based fuel; and
wherein the riser and the moving-bed reactor share a common wall.
