The mat is squeezed in a continuous steam injection squeezing machine 2 to a plate shape 3 and then passes through a rear adjustment unit 4. Gas exhaust and steam generated in the squeezing process are captured. As the exhaust and steam mix with the escaping air from the surroundings, hot air is provided to prevent condensation of the gas exhaust and steam and to carry the steam and exhaust to a combustion plant for combustion.

。[0003] A well-known problem with current manufacturing techniques, whether involving intermittent or continuous squeezing, is the generation of gas at high temperatures in the squeezing machine during the squeezing process. These gases consist of water vapor (steam), different volatiles dissolved wood and glue, so-called volatile organic compounds (VOC), and gaseous phenol from wood and glue. Long-term exposure to these substances gives a pungent odor and high concentrations have been shown to be harmful to health. Therefore, authorities in the majority of countries where boards are manufactured according to the methods described above have struggled to establish rules indicating acceptable exhaust concentrations in the workplace and acceptable concentrations in emissions to the atmosphere.

The effect of these gases on the working environment can be limited to some extent by protective casings and covers, even if room temperature air is normally used as conveying air due to the large size of the press. Thus, this volume of air typically exceeds the combustion air requirements of a factory's standard heating plant. This has required complex and expensive equipment facilities in connection with the majority of plants producing lignocellulose sheets and plates. For example, plants are usually equipped with a so-called RTO (Regener

デヒドの排出は、蒸気の発生を伴う。[0007] The plant shown in the figures is based on the plant disclosed in Swedish patents 502,272 and 504,638 which describe two continuous steam pressing processes. The fibrous mat 1 previously formed in the manufacturing process is squeezed by a continuous steam injection squeezing machine 2 to form a plate or sheet 3, and then the plate or sheet 3 is passed through a rear adjustment unit 4. As the fibrous mat 1 passes through the nip between the two steam injection rollers 5, steam is added to the mat via wires 6 and injected. At this time, the temperature rapidly rises to 100 ° C. or higher, usually to 120 ° C. or higher. The mat thereby becomes a solid plate 3. The pressure drops as the plate leaves the nip between the steam injection rollers 5, while the temperature drops rapidly to around 100 ° C. This is caused by extremely rapid vaporization of some of the enclosed moisture. VOC emissions and formaldehyde emissions are accompanied by the generation of steam.

Vapors and other exhaust air are trapped by a suction unit 8 provided inside the press before it can escape to the workplace or the surrounding environment. Air heated to a temperature above 100 ° C. is sent to this suction unit. The hot air is used together with air leaking from the surroundings as steam and the other exhaust carrier gas described above. The hot air, leaking air, steam and exhaust are sent to a heating plant 9 in the factory for combustion. The hot air delivery unit 11 is connected to the curing zone 10 in the press 2 and the supplied hot air then proceeds to the suction unit 8.

Maintained at high temperatures. This allows the total amount of air and gas to be maintained at a level that does not exceed the volume of combustion air required by a standard plant system that generates the heat and process steam needed to manufacture the board. Therefore, there is no need to install other equipment to prevent exhaust to the surroundings.

Through the rear adjustment unit 4 (see Swedish Patent 504,638). The air exiting the rear conditioning unit contains VOC and formaldehyde emissions, albeit in small amounts, and most of the emissions are generated in continuous steam injection presses, as measured by experimental plants. For this purpose, a suction unit 12 is arranged in the rear adjustment unit 4. Air is drawn in at section 13, heated by heater 14,

As one proceeds, the air is energized through the medium of the heat exchanger 17.
If the air from the rear conditioning unit 4 is excessive, the excess can be mixed with the flow from the press 2 in the closed hood 18 and passed to the heating plant 9. If there is a shortage of air to the curing zone 10, the suction fan 16 draws excess air through the sealing hood 18. The air leaving the rear conditioning unit 4 is used as hot input air for the internal suction unit 8 of the continuous steam injection press. Experiments have shown that these volumes sufficiently satisfy the transport volume required for a continuous steam injection press.

This latter press also includes a special suction unit which functions to capture in the press the exhaust carried by the hot air to the factory combustion plant for the production of heat and steam.
