    摘要: A hybrid combustion system is provided combining advantages of a fluidized bed combustion portion and a pulverized coal combustion portion. The former portion includes a fluidized bed chamber, a coal mill without an air separator, a recycling duct connected to the coal mill, a coal supply duct, and a spray feeder. The fluidized coal combustion portion includes a pulverizing coal mill with air separator, a blowing duct for blowing ground coal, at least one pulverized coal burner and an air recycling duct for recycling combustion air. Fluidized bed combustion takes place in a lower part of the system and pulverized coal combustion takes place above the fluidized bed combustion. Each of the portions may be independently operated of the other. A main combustion chamber is common to both the fluidized bed portion and the pulverized coal portion. A related process is also described.

    摘要: The equipment according to the invention is suitable for the measurement of very small weight forces by conversion of the forces to be measured to 5-100-fold value. The equipment has two units, each containing at least three measuring arms, where the connection points of the measuring arms are attached to an extension bar, and the free ends of the measuring arms are connected to a single rigid element in such a way, that the connection points of the measuring arms are outside the planes fixed by the ends attached to the rigid element. The measuring arms and extension bar in the equipment are formed as pull rods. The measuring arms are arranged symmetrically or asymmetrically, and their number is optional. Infinite number of measuring arms may be used, in which case they are formed as membranes in the practice. Force-meter sensors, suitably elongation measuring resistors are built into the measuring arms, thus the output signal gives directly the measured value.
