The present invention provides a method and system for generating electricity using a drive for the electrical generator that is powered by an engine (e.g., turbine). The method and system uses high pressure hot gases produced by combustion of a fuel and an oxygen-bearing gas, using at least a portion of the electricity generated to power manufacturing plant equipment. Additionally, hot waste gases from the heat engine are transported to a process dryer (e.g., rotary kiln dryers) to dry minerals, salt, pigments, sands, and clay.

A combination of components for use in making asphalt concrete from a mixture of virgin aggregate material with recycled asphalt products and/or recycled asphalt shingles encompasses a direct dryer for heating virgin aggregate material; a pre-dryer for heating recycled asphalt product and/or recycled asphalt shingles, said pre-dryer using warm exhaust gas from said direct dryer to heat the recycled asphalt product and/or recycled asphalt shingles; and means for conveying warm exhaust gas from said direct dryer to said pre-dryer.

A method for efficient utilization of hot air flows in a dryer system for goods to be dried is provided, in particular for a vehicle painting plant. Waste air from the dryer is heated in a thermal post-combustion plant and, as clean gas is conducted through circulating air recuperators, the circulating air extracted from the dryer is heated up and returned into the dryer. A device for efficient utilization of the hot air flows in a dryer system for goods to be dried is also provided, in particular for a vehicle painting system. The device includes a dryer, the waste air of which is heated in a thermal post-combustion plant. Clean gas is fed to circulating air recuperators and at least one fresh air recuperator. At least one additional heat source for the clean gas is also provided.

The invention relates to a continuous flow dryer (10) for drying a material (14) by means of hot air (24), comprising a first and a second section (20, 22), which in a transport direction (18) are successively passed through by the material (14), and which in terms of flow are separated to a great extent. The invention is characterized in that a fresh air supply device (28) for supplying fresh air (26) as first infeed air (32) into the first section (20) is provided, an exhaust air recirculation device (44) for removing exhaust air (40) from the second section (22) and for recirculating exhaust air (40) as second infeed air (42) back into the second section (22) is provided. Furthermore, a heat exchanger (58) is provided, through which the fresh air (26) on the one hand and the exhaust air (40) on the other hand are guided, for transferring waste heat (62) of the exhaust air (40) into the fresh air (26).

An apparatus for drying an electrode plate includes a drying furnace configure to dry an electrode plate having a slurry coated thereon, an over-heated steam supplier configured to supply the drying furnace with over-heated steam as a drying heat source, a circulation fan configured to inhale at least some of the over-heated steam discharged from the drying furnace and to introduce the inhaled over-heated steam back into the drying furnace, an exhaust fan configured to inhale at least some of the gas exhausted from the drying furnace, and a heat exchanger configured to exchange heat of the exhaust gas supplied from the exhaust fan.

A heater (160) is provided for use in curing tobacco or other similar processes. The heater comprises: a furnace (211) having a chamber in which to burn fuel to generate heat; and a heat exchanger (230) for transferring heat from the heater to an airflow for use in curing the tobacco or other similar process. The airflow passes outside the heater. The heat exchanger has one or more pipes (220B-2,220A-2) that connect into the chamber of the furnace and is integrated into the furnace. For example, the heat exchanger may have a plurality of pipes (220B-2,220A-2) that connect into the chamber of the furnace, wherein the plurality of pipes (220B-2,220A-2) comprises two rows of pipes, one on each side of the furnace. The heat exchanger may further include a plenum (231B, 231A), wherein each of the pipes (220B-2,220A-2) leads upwards from the furnace chamber (211) to the plenum (231B, 231A). The heat exchanger may be integrated into the furnace by the use of one or more welded junctions.

The invention relates to a device and a method for the bonding of a textile web, whereby the textile web is guided over an idler drum into a bonding plant, led around a through-air drum and over a cooling drum and then led out again, whereby heated fresh air flows through the web and the through-air drum and the exhaust air is extracted from the bonding plant. According to the invention, it is intended that cooling air is directed onto the web ahead of the detachment point of the web from the through-air drum onto the web.

An electrode manufacturing facility includes a dryer, a first pipe, a solvent collection device, an outside air inlet pipe, a heat exchanger, and a second pipe. The first pipe sends an exhaust gas expelled from the dryer to the solvent collection device. The solvent collection device causes an organic solvent contained in the exhaust gas expelled from the dryer to dissolve into water to collect the organic solvent. The heat exchanger exchanges heat between the exhaust gas expelled from the dryer and the outside air inlet pipe. The second pipe is connected to a pipe to which the exhaust gas after having passed through the solvent collection device is expelled and to a portion of the outside air inlet pipe located upstream of the heat exchanger, and sends at least a portion of the exhaust gas after having passed through the solvent collection device to the outside air inlet pipe.

To provide a coating drier facility that has only a small heat loss and saves energy, a coating drier facility includes: a drier chamber configured to dry a coated object; a heater for heating air; an air supplier for supplying the air heated by the heater into the drier chamber; an air collector for collecting air from the drier chamber; and a treatment device for treating a volatile substance in the air that the air collector has collected, wherein the heater doubles as the treatment device.

A device for controlling the temperature of objects, in particular for drying coated vehicle bodies, and method for controlling the device, the device having a temperature control chamber and a cooling region connected to the temperature control chamber, a temperature control device for generating temperature control air, a control apparatus, and a heat exchanger. The heat exchanger has an outside air inlet, a hot air inlet connected to the cooling region and/or the temperature control device, and a cooling air outlet connected to the cooling region, and the control apparatus is designed to control the temperature of the outside air supplied via the outside air inlet using hot air supplied via the hot air inlet.
