摘要： In order to dry boards, the boards are guided on racks through a drier and brought into contact with drying air in two stages. In a stage A with a higher drying power, the drying air is supplied at a higher temperature and with an at least average humidity, and in the other stage B, it is supplied at an average temperature and with a low humidity. The waste heat of the outgoing air from stage A is used for preheating the drying air. This process should reduce the consumption of primary energy. For that purpose, a process is known that consists of also using the outgoing air condensation heat. This has the inconvenience, however, of requiring substantially more secondary energy, as important air mass flows are required to transfer heat because of the low condensation temperature. Primary energy should be reduced by using condensation heat without substantially increasing secondary energy requirements. According to the invention, the outgoing air from stage A is supplied to stage B through a heat exchanger arranged in the rack of the drier. The drying air of stage B is supplied in counter-current through the drier with a low humidity and temperature, so that the boards are dried in stage B both by condensation heat and by radiant heat. Thus only a reduced mass flow of drying air is required to transfer the condensation heat. The consumption of primary and secondary energy is low. This invention is suitable for drying boards as for buildings and gypsum plain boards or fiber boards.

摘要： A method of and apparatus for producing gypsum fiber boards includes introducing shaped boards provided of a mash of calcium sulphate dihydrate and fibrous material and possibly additives after dewatering and shaping the mash into at least one pressure vessel and to heat the boards at saturated steam atmosphere to 120.degree.-160.degree. C. over a predetermined period. Thereafter, the boards are allowed to cool down within the pressure vessel to a temperature of about 100.degree. or less before being discharged therefrom.

摘要： An apparatus for preparing multiphase gypsum and particularly wall plaster which has an exactly defined composition comprises a plurality of heating stages including at least one high temperature stage and at least two first and second separate low temperature stages. Heating gases are directed from a combustion chamber first to the high temperature stage and subsequently into each of the lower temperature stages. One of the low temperature stages is employed as a pre-burner and it is fed with materials from a common storage bin to pre-burn the material and then direct it to the high temperature stage. The other stage is provided with the heating gases from the high temperature stage and in addition it is controlled as to temperature, humidity and quantity of heating gases in its products together with the high temperature stage products after treatment are delivered to a common cooling device.
