摘要： The invention relates to a process for the purification of flue gases by feeding (7) limestone into the furnace (1) of a boiler, by separating (3) the dusts from the flue gases at a point after the furnace, by hydrogenating (14) the separated dust, which contains calcium oxide, by returning (12, 13) it to the flue-gas flow (11) at a point after the separation point but before the reaction zone (4), in which additional water or vapor is fed (15) into the dust-bearing flue gas, whereafter the dust which contains sulfated calcium hydroxide is separated (5) from the flue gases (6) thus purified. According to the invention, the hot, dust-bearing flue gas coming from the furnace is divided in the separation zone (3) into a dust-poor main flow (11) and a dust-rich secondary flow (12), vapor or water mist (14) being fed into the secondary flow at a point at which the temperature of the secondary flow is 300-600 DEG C. The invention also relates to an apparatus, such as a cyclone, intended for use in this process and having nozzles (19) for feeding in steam or for atomizing water, and a connecting duct (12) between the separation device (3) and the flue-gas duct (11) for the purpose of making the activated dust-rich secondaryflow of flue gas to join the dust-poor main flow at a point after the cyclone (3).

According to the method, the pressure difference across the hydrocyclone (1) is kept substantially constant by raising the pressure of the pulp conducted to the hydrocyclone (1) by a pump (3) preceding the hydrocyclone (1) and by returning part of the purified pulp discharged from the hydrocyclone to the inlet channel (2) of the pulp before the pump (3) so that substantially a constant amount of pulp flows through the hydrocyclone (1) in a unit of time. The separating apparatus comprises a pump (3) mounted in the inlet channel (2) of the pulp, a return channel (12) running from the outlet channel (11) to the inlet channel (2) before the pump (3) and provided with a valve (13), and a pressure difference regulator (17) provided with pressure sensors (14, 16) and arranged by means of the sensors (14, 16) to measure the pressure difference across the hydrocyclone (1) and to adjust the valve (13) so that the pressure difference remains substantially constant.

摘要： The application of the electron beam technique in the polymerization of surfaces and purification of flue gases, for instance, often has a high demand of energy. The performance of prior art emitters, often considerably less than 50 %, is thereby a major drawback. In the present method, low-energy shaping acceleration is applied first and thereafter the electrons are passed through windows very ideally and homogeneously by the proper acceleration. By means of the method, several successive and/or parallel windows can be provided in the device, the electron power being distributed evenly between said windows.

摘要： A method of combustion and an apparatus for the reduction of the formation of nitrogen oxides in a combustion process. In the method the air required for the burning is introduced into a furnace (2) in at least two stages so that in the first stage the coefficient of air ranges preferably from 0.90 to 0.97 while the combustion is carried out under understoichiometric conditions, and in at least one stage so that the total coefficient of air exceeds the value one. According to the method the gases formed in the first combustion stage are cooled to a lower temperature while introducing more air among the gases at the earliest in connection with the cooling. The introduction of air is carried out so that the total coefficent of air at each particular point within the furnace (2) is at the most such as would be required by the temperature of the gases at this particular point for a concentration of nitrogen monoxide not exceeding a predetermined value to be formed in the gases. The apparatus comprises a superheater (7) which effects cooling in the furnace (2) of the boiler (1) after the first combustion stage and through which the gases formed in the first stage are forced to flow. More air for the final combustion is introduced at the superheater (7) and/or after it.

摘要： A hydraulic piston cylinder device comprising a cylinder (1), a piston (2) dividing the cylinder into two cylinder spaces (A and B), and valve elements (7, 9) between the cylinder spaces (A and B) and the respective pressure medium pipes (11, 12). The problem is to accomplish a hydraulic piston cylinder device in which the pressing or tractive force of the cylinder is maintained even if the external pressure led into the cylinder would stop. To solve this problem, the piston (2) is elastically compressible by the pressure of the cylinder (1) and the valve members (7, 9) are coupled to each other so that when one of the valve members (7 or 9) is closed the other (9 or 7) cannot be closed. The piston is divided in the axial direction into two successive parts (21, 22) spaced from each other, between which parts there is elastic material (3).
