    摘要： A method and an arrangement for treating wet material which is difficult to treat, such as sewage sludge, by combustion, wherein the material being treated is dried in a steam dryer (3) and the dried matter is combusted in a combustion apparatus (1). For the heat requirement of the steam dryer (3), steam is superheated by the aid of the thermal energy generated by the material combusted in the combustion apparatus (1), and the superheated steam is taken to the steam dryer (3) for drying the material being treated. The amount of heat released from the fuel in the combustion apparatus (1) is transferred into the steam circuit of the steam dryer (3) in its entirety.

    摘要： A method and apparatus for feeding solid fuel such as coal or peat into a pressurized boiler, dryer or other similar pressurized space. The method uses as the fuel feeder a rotating cylinder/ram piston feeder comprising two feed cylinders (3). The goal of the invention is accomplished by reducing the pressure in the gate feed cylinder (3) prior to moving the feed cylinder to the position corresponding to the pressure level preceding the filling step of the cylinder and then keeping the cylinder pressure at a reduced pressure level during the transfer step between the filling step and the connection step for discharging into the pressurized space and, after the transfer step, finally elevating the cylinder pressure just prior to the connection for discharging into the pressurized space.

    摘要： The present invention relates to an assembly for providing a laminar gas flow serving, e.g., to form a fluidized mixture of solids with a gas, said assembly comprising a plenum chamber (3) forming a closed space containing a gas infeed pipe (5) for blowing gas into the plenum chamber and a feeder pipe (1) into which said laminar flow is to be formed and whose one end (2) is adapted into said plenum chamber. The lower end (2) of said feeder tube (1) adapted into said plenum chamber (3) is formed into a diffuser mouth (8) of rotationally symmetrical shape having its inner diameter flared in a horn-like manner so that the inner diameter of the tube end is expanded smoothly toward the rim of its diffuser mouth facing the bottom of said plenum chamber (3), and the bottom (10) of said plenum chamber (3) at the area facing said mouth (8) is adapted at a constant distance from the rim of said mouth (8) over the area facing the perimeter of the mouth.

    摘要： The invention concerns an integration construction between a steam boiler and a steam turbine and a method for preheating of the supply water. In the integration construction the steam is passed from the steam boiler (10) along the duct (24a) into the steam turbine (11) so as to rotate the electric generator (12) which generates electricity. The economizer (23) consists of at least two parts, comprising at least one first economizer part (23') and at least one second economizer part (23''). The supply water is passed from the cold economizer part (23') to a supply-water preheater, which consists of a heat exchanger (24) in which thermal energy is transferred from bled steams of the steam turbine, either directly or through a medium, preferably water, into the supply water. After this, the supply water, which had been preheated by means of bled steams from the steam turbine, is passed in the steam boiler (10) into the hot economizer part (23'') and further to the vaporizer (240) and into the superheater (24) and through the superheater into the steam turbine.
