Abstract: A system for combined production of yellow phosphorous and syngas is disclosed. The air separation unit, the pulverized coal preparation unit and the mineral aggregate forming unit are respectively connected to a gas inlet and a top feeding port of the phosphorus coal gasifier; phosphorus-containing syngas obtained from phosphorus coal gasifier is connected to a gas inlet of the separating washing unit through an outlet of the phosphorous coal gasifier; Yellow phosphorus products and crude syngas are respectively output from the output port of the separating washing unit; and then the crude syngas is purified to obtain refined syngas. A slag discharge port at the bottom of the phosphorus coal gasifier is connected to an input port of a slag cold quenching unit. The system can improve the available energy of yellow phosphorous production, the production capacity of yellow phosphorus and the yield of syngas, and reduce CO2 emission.
