rocess for the operation of coal steam-generating plant where, at the combustible inlet side is interposed a milling and drying installation wherein there is conducted, as drying gas, hot flue gas sucked from the combustion chamber 2 of the steam-generating plant, via a flue gas suction conduct 6. Primary combustion air or, in some cases, recycled cold flue gases are mixed with the drying gas to regulate the cooling of this last; the quantity of the aforementioned cooling regulating means is adaptable in relation to the predefined temperature of the drying gas which is measured before or /and after the milling and drying installation, where a part of the cooling regulating means is substituted for the refrigerating water drawn into the flue gas suction conduct and the drying flue gas is cooled to produce the adequate temperature for the evaporation of the refrigerating water; it is also proposed an arrangement for the realization of this process (fig. 1). |
