    Abstract: The invention relates to an indirect heating system in which a solid fuel circulates in the form of particles. The inventive system comprises a grinding station, a furnace (7), at least one intermediate silo, a separator, at least one cyclone and, optionally, a gas recirculation fan. The invention is characterised in that a dust extractor (10) captures the finest particles which are subsequently introduced into the furnace (7) by means of at least one specific conduit (52) and burnt by at least one specific burner (71). The aforementioned ultra-fine particles are then stored in a specific silo (10), dosed into a feeding device (61), mixed in well defined proportions with hot air and conveyed to the specific burner (71) through the specific conduit (52).

    Abstract: A method for producing pulverized coal including the steps of providing a drying gas heated to a predefined temperature in a hot gas generator; feeding the heated drying gas into a pulverizer; introducing raw coal into the pulverizer, the pulverizer grinding the raw coal into pulverized coal; collecting a mixture of drying gas and pulverized coal from the pulverizer and feeding the mixture to a filter, the filter separating the dried pulverized coal from the drying gas; collecting the dried pulverized coal for further use and feeding the drying gas from the filter to an exhaust line; and collecting the drying gas exiting the filter and feeding part of the collected drying gas to a recirculation line for feeding recirculation drying gas to the hot gas generator. According to an important aspect of the present invention, the step of providing the drying gas includes feeding a variable flow rate of hot stove waste gas to the hot gas generator through a hot stove waste gas line so as to maximize the amount of hot stove waste gas used as drying gas. A pressure of the drying gas at a pulverizer gas inlet is controlled by regulating a flow rate of the hot stove waste gas through the hot stove waste gas line.
