A drying oven for crosslinking a continuous mat of mineral or plant fibers includes a plurality of heating boxes through which the mat of fibers successively passes. At least one of the boxes includes, between an external insulating jacket of the drying oven and a central compartment of the box, an in-built hot-gas heating and recirculation device that includes at least one radial turbine mounted horizontally, the axis of rotation of which is arranged vertically, the turbine drawing hot gas along the axis through a gas outlet orifice of the central compartment after it has passed through the mat, and discharging it radially toward a recirculation device that recirculates the hot gas leaving the radial turbine to a gas inlet orifice of the compartment, and at least one heating device for heating the gas circulating in the box.

The invention relates to a process for processing an adhesive, wherein the process comprises applying an adhesive precursor product onto an adhesive carrier and activating and crosslinking the adhesive precursor product by treating the adhesive precursor product with water vapor and heat in a reaction chamber, and wherein the process is characterized in that air mixed with reaction gases forming during the activation and crosslinking in the reaction chamber is conducted away from the reaction chamber and recirculated as circulating air into the reaction chamber, wherein a portion of used air of the air recirculated as circulating air is replaced by fresh air. The invention further relates to a corresponding device for processing a pressure sensitive hot-melt adhesive.

A system for treating objects includes a device for tempering objects in which a tempering tunnel having at least one air outlet and at least one air inlet is arranged in a housing. At least one heating unit, in which a hot primary gas flow can be generated, is assigned to the tempering tunnel, wherein the hot primary gas can be guided into a circulating air heat exchanger, in which air from the tempering tunnel can be heated by hot primary gas as circulating air, which can be fed back to the tempering tunnel in a circuit via the at least one air inlet. The heating unit is coupled in the manner of a combined heating and power plant to an electric generator in such a way that electrical energy is produced during operation of the heating unit.

The invention relates to a lignite fired steam power plant comprising a water/steam power cycle, a dryer system for drying lignite coal and a heat recovery system for recovering thermal energy from the dryer system. The heat recovery system vaporises condensate against a vapour line of the dryer steam and then compresses the vaporised condensate for use to preheat either or both combustion air or condensate of the water/steam power cycle.

The invention relates to a drying device for forming a coating with at least one defined coating parameter in the cavity of a metal can, including a drying chamber through which the cans can be moved; adjustment means which have two or more controllable adjustment variables, wherein the adjustment means are arranged and designed so as to adjust the at least one coating parameter of the coating; and a controller, which is coupled to the adjustment means so as to transmit signals and which is designed to control the two or more adjustment variables on the basis of at least one can parameter such that the coating is formed with the at least one defined coating parameter.

A dishwasher drying system includes an air inlet configured to receive hot, humid air from a tub of a dishwasher. The dishwasher drying system also includes an air outlet configured to discharge the air to an ambient environment outside the dishwasher. The dishwasher drying system further includes an air moving device configured to cause the air to move from the air inlet to the air outlet. In addition, the dishwasher drying system includes a thermal storage heat exchanger positioned within an airflow path of the moving air, the thermal storage heat exchanger configured to absorb heat and condense moisture from the moving air as the moving air contacts the thermal storage heat exchanger during a dishwasher drying cycle.

A multi-stage separation heat-exchange type drying system is provided. A plurality of first heat exchange blocks of the first main body are installed to be spaced from each other at a predetermined interval, and first vortex generating blocks are installed between the first heat exchange blocks. Also, a plurality of second heat exchange blocks of the second main body are installed to be spaced apart from each other at a predetermined interval, and second vortex generating blocks are installed between the second heat exchange blocks. The heat exchange occurs in a manner that the first heat exchange blocks and the second heat exchange blocks corresponding to each other, positioned up and down, exchange a heat medium therebetween.

The present invention relates to a coal supply device for reducing dust of coal input for dry and supplying dispersing and supplying the coal in a system for drying coal using reheat steam, and more particularly, to a device to minimize dust when the coal is supplied to a multi-stage dryer from a coal constant feeder through a pulverizer in a multi-stage dryer for drying coal using reheat steam and disperse and supply the coal to a transfer device and a coal drying system in which coal which is primarily dried in the first coal dryer is inputted into the second coal dryer and thus is secondarily dried, includes a coal constant feeder supplying a predetermined amount of coal onto the upward surface of the first transfer plate; and a dust reducer constituted by an inlet pipe coupled to an outlet of the coal constant feeder by a bearing, a worm wheel coupled onto the outer periphery of the inlet pipe, a worm gear-coupled with the worm wheel and rotating with rotary force transferred from a motor, a curved pipe of which the top is coupled to the inlet pipe, and an outlet pipe coupled to the end of the curved pipe, wherein the dust reducer which rotates at the predetermined velocity reduces the velocity of the coal supplied by the coal constant feeder to minimize generation of dust from the coal input onto the upward surface of the first transfer plate.
