The function of Section 100, Gasification, is to produce raw, low-Btu, cooled, high-pressure gas from coal in a two-stage, slagging, entrained-flow gasifier with char recycled to extinction. Section 100 is made up of the following key areas: Coal Handling; Coal Pulverizing and Drying; High-Pressure Solids Feeding (Petrocarb); Coal Gasification; Slag Handling; Char Separation, Char Cooling, and Recycle Gas System; Gas Cooling and Superheated Steam Production; and a Gasifier Start-Up System. The coal handling system unloads raw coal from rail cars and crushes and transports it to coal storage hoppers. The coal pulverizing and drying system pulverizes the crushed coal and dries the coal to achieve a zero surface moisture. The high-pressure solids feeding system provides continuous, high-pressure, accurately controlled solid flows of pulverized coal, limestone fluxing agent, and recycled char. The gasification area consists of a two-stage, entrained-flow, high-pressure, slagging, ''Bi-Gas'' coal gasifier, which receives dry pulverized coal, steam, and air and produces high-temperature, high-pressure, sulfur-containing, low-Btu gas and hot molten slag. The slag handling system receives the hot, molten slag from the gasifier and cools and frits it. The char separation, char cooling, and recycle gas systems separate the char from the gas, cool it with recycle gas to a temperature mechanically acceptable to the Petrocarb solids feeding system, and recycle it to this system. The gas cooling system cools the raw gas before it goes to the gas purification sections and produces superheated, high-pressure steam. The gasifier start-up system quenches the hot gasifier effluent gas and char produced during start-up of the gasifier.
