1. A system, comprising:
a fuel slurry preparation system, comprising:
a grinding mill configured to receive a solid fuel and a liquid, to reduce a particle size of the solid fuel, and to mix the solid fuel with the liquid to form a first fuel slurry having a first solids concentration;a closed vessel disposed downstream from and fluidly coupled to the grinding mill, wherein the closed vessel is configured to receive the first fuel slurry from the grinding mill and to hold the first fuel slurry;a heat source coupled to the closed vessel and to a steam source in a gasification plant, the heat source being configured to receive steam generated in the gasification plant, wherein the heat source is configured to heat the first fuel slurry;a fuel supply unit disposed downstream from the grinding mill, the closed vessel, and the heat source, wherein the fuel supply unit is configured to provide an additional amount of solid fuel to the first fuel slurry downstream of the closed vessel to adjust a solids concentration of the first fuel slurry and generate a second fuel slurry having a second solids concentration that is greater than the first solids concentration; a control system configured to control the heat source to heat the first fuel slurry while the first fuel slurry is in the closed vessel to decrease a viscosity of the first fuel slurry below a threshold viscosity, within the closed vessel and the control system is configured to control the additional amount of solid fuel provided to the first fuel slurry by the fuel supply unit in response to a monitored viscosity or solids concentration of the first fuel slurry; and a gasifier fluidly coupled to the closed vessel, wherein the gasifier is configured to receive the second fuel slurry and gasify the second fuel slurry to produce syngas. |
