摘要： A method and apparatus for treating a wet or moist lignocellulosic material at a moisture content which is in a range from above the Xfsp value of the material down to about 0.1 kg water/kg dry below the Xfsp value, where Xfsp is the fiber saturation point value, with rapid warming of the wet or moist lignocellulosic material to a level that natural polymers in the lignocellulosic material soften, which changes the microstructure and results in improved properties of the lignocellulosic material.

摘要： A method for controlling the curl of paper in which steam treatment and/or moistening of the paper web is/are carried out after the calendering process being performed in the calender. In processes in which calendering is not employed, the curl is controlled in connection with a machine reel-up or in process steps carried out after the machine reel-up. A paper or board machine applying the method includes a headbox, a former, a press, a dryer section and steam boxes, moistening devices, an IR dryer and/or equivalent curl control devices. The steam boxes, moistening devices, IR dryers and/or equivalent curl control devices for the control of the curl are arranged after the calender or, if no calender is employed, in connection with a machine reel-up or a finishing process carried out after the machine reel-up.

摘要： The disclosed cylinder for heat-treating a web is rotatable about a horizontal axis and is heated by one or multiple stationary infrared burners that extend all along the length of the cylinder, but which are limited to an arcuate extent, establishing a maximum cylinder heat output when the burner(s) is (are) supplied with air-fuel mixture at their maximum rate. Reduction of the air-fuel supply rate over a wide range allows the cylinder heat output to be reduced as the web processing speed is reduced. When the burner is divided into segments, the temperature profile along the cylinder; i.e., across the width of the web, can be regulated to adjust the moisture profile of the web. An exhaust manifold within and along the cylinder is configured so as to avoid any local accumulation of high-temperature exhaust.

摘要： A power control system for the heat lamps for typically drying a continuous web of paper in order to provide a linear moisture profile locates the actuating thyristor type switch at each zone where the heater lamps themselves are located. Thus, computer control can be centralized and wiring minimized. The parameters of minimum flicker for unity power factor and high resolution power control are achieved by utilizing the timing signals provided by the zero crossings of the three-phase AC line voltage input and controlling either half cycles or partial half cycles for each zone. Computing time is reduced by providing for scratch pad memory tables which can rapidly be scanned or sequenced through by a zone pointer.

摘要： Improved burner constructions for gas-fired infra-red generators having ceramic fiber matrix through the thickness of which gaseous combustion mixture is passed and as it emerges it is burned to heat emerging surface to incandescence. Burner matrix can be loaded with silicon carbide particles to improve its emissivity, can be made water-repellent and its uniformity can be improved. Burner body can be casting, with sheet metal addition to form a baffle and air-seal and to grip matrix edges. Combustion mixture plenum can have movable partition assembly separating it from air seals, to adjust portion of matrix at which incandescence is generated. Metal screen can be stretched in front of incandescent surface to assist with low-temperature operation. Large size matrix can have central support fitted and secured to back of burner body. Air seal can be provided by narrow curtain of air extending around internal faces of burner body. Annealing lehr is desirably provided with gas-fired infra-red irradiation, and can have heat losses reduced by diminishing amount of metal used as in a conveyor to move workpieces through.
