Title: The simultaneous production of coal gas and electricity
Inventor: WOLF OTTO
IPC: C10B57/04
Filed: 1957-01-22
Abstract: 857,919. Coking coal. STEINMULLER G.m.b.H., L. & C. Jan. 22, 1957, No. 2316/57. Class 55 (1). In a process for the simultaneous production of electricity and coal gas from coal, the coal is powdered, pre-oxidized whilst conveyed in suspension in a gaseous carrier, carbonized whilst in suspension in a gaseous carrier in a degasifying shaft and then the coke and coal gas separated, the coke being burned to heat water or air in a pressure vessel for driving a turbo-generator, the arrangement being such that the heat necessary for pre-oxidizing and/or carbonizing the coal is supplied at least partly from the combustion of the coke to heat the pressure vessel and at least some of the heat from the gas and coke is transferred to the pressure vessel. The coal may be suspended in part of the resultant gas as carrier gas, air being introduced for partial combustion and oxidation, the preoxidized coal then being conveyed through the degasifying shaft to a coarse dust extraction plant from which the hot coke is fed directly to the burners of the pressure vessel. The gas then gives up its heat to boiler parts in the form of partitions or panels before entering a fine dust extraction plant and a by-products recovery plant. The boiler parts may be surfaces for preheating boiler feed water or combustion air. The furnace gas from the pressure vessel gives up some of its heat to the degasifying shaft and then passes evaporators, water or air preheaters which cool the furnace gas further. The various heat exchangers are arranged to be switched in and out of use to vary the temperature of the heating gases and therefore the degree of degasification and tar cracking. Alternatively gases of lower temperature may be mixed with the heating gases. To vary the amount of steam or hot air produced so as to vary the electricity output, uncoked cool, coal gas, or tar may be burnt in addition to the coke produced. The partitions or panels in the degasifying shape may be cleared by raining balls thereon.
