摘要： The invention relates to a method and system for a paper machine comprising calculating the heat recovery heat flow Q rec , the heat flow Q pw required for heating the process water, the heat flow Q MR required for heating the ventilation air of machine room ventilation, Q sup required for heating the supply air of the dryer section and the evaporation amount m ev of the dryer section. Also the dimensioned evaporation amount in the dyer section m ev, dim is determined and the values are used for calculating the heat recovery efficiency EFF rec by the formula: EFF rec = (Q rec /(Q pw + Q MR + Q sup ))*(m ev, dim /m ev ). The invention relates also product comprising program code elements disposed to perform the steps of the method.

摘要： An insulated hood of a paper machine, in which hood at least a wall, a door element or a roof has been constructed by arranging at least a first element (10) and a second element (11) in contact with each other. The elements comprise two essentially parallel planar surfaces (12a, 12b), an insulation material (13) between the surfaces, and watertight edges. The gap between the first and the second surface (12a, 12b) comprising the insulation material (13) is free of frame structures of the hood.

摘要： The invention relates to an arrangement and a method in connection with an impingement dryer (10, 20, 30) of a fiber web (50). According to the invention in the method: - the fiber web (50) is guided into the impingement dryer (10, 20, 30) via its first end (11, 21, 31 ), - the fiber web is guided inside the impingement dryer past blowing means (104) and exhaust means (105), and - the fiber web is guided out via a second end (12, 22, 32) of the impingement dryer, - during a web break or tail threading, the fiber web is guided into a desired direction by means of a guiding form (304, 317) arranged in the first end (11, 21, 31) or the second end (12, 22, 32) of the impingement dryer, on the outer surface (303) of the impingement dryer, and having, in the machine cross direction, at least the width of mainly the entire dryer.

摘要： A method for drying a paper web, in which method a paper web is dried with at least one dryer unit, in which a paper web to be dried formed on a support fabric (2) is conveyed over a surface of a heated drying cylinder (3), whereby the second surface of the paper web is against the first surface of the support fabric (2), and air is blown toward the second surface of the support fabric (2), and in which method the surface of the drying cylinder (3) is heated to a temperature of 130―200 °C and the temperature of the air to be blown to at the most about 70°C. The invention also relates to an arrangement in a drying section of a paper machine for implementing the above-mentioned method.
