Abstract: One embodiment of the present disclosure relates to a combustor assembly which has a burner assembly and a combustor. The burner assembly has a body having a first end and a second end and a center passageway. The center passageway extends between the first end and the second end of the body. The body of the burner assembly is provided with a biomass inlet for receiving biomass, a primary air inlet for receiving air, a gas inlet for receiving gas, and a secondary air inlet for receiving air. The biomass inlet is in communication with the center passageway.

Abstract: In a hardware accelerator for preamble detection of a Physical Random Access Channel (PRACH) in a CDMA based communication system, buffering means stores input samples received at an antenna at a first rate, addressing means read a predetermined consecutive number of the input samples in parallel at a second different rate. The hardware accelerator is further partitioned into a reusable unit providing code correlation, and a preamble detection dedicated unit providing signature code despreading. The reusable unit comprises means for correlating at least a subset of the previously read input samples with a predetermined code to provide a correlation output for a number of time lags. The preamble detection dedicated unit comprises means for preamble detection configured for providing Hadamard Transformation of the correlation output to enable preamble detection, and all means are arranged on a single hardware chip to enable high-speed data transmissions between the respective means.

Abstract: A flexible and resource-efficient despreading-on-demand (DoD) technique is described where only channels that actually contain data to be despread are despread, and only a single despreading operation need be performed using the actual spreading factor associated with that data. In one example, the data portion of the received signal is buffered for a frame so that an associated transport format, including the actual spreading factor, can be determined before the data is despread. The data is buffered in a memory at a first rate and then subsequently read out at a second rate that is considerably faster than the first rate. The fast data read-out allows despreading at a high rate so that the despread data symbols from the buffered frame are available for further processing shortly after the last sample belonging to the frame has been received.

Abstract: A fuel additive composition for the reduction/removal of vanadium-containing ash deposits in gas turbines and other by combustion of vanadium-containing fuel driven apparatuses, which composition as its active ingredient comprises a compound of a metal capable of forming a vanadate with vanadium of said ash deposits is disclosed.

Abstract: Centrifugal separator, the separation chamber (9) of which is surrounded by a first rotor part (1) and a second rotor part (2), an annular flange portion (3) of the first rotor part (1) being axially inserted into a sleeve formed end portion (5) of the second rotor part (2) and connected thereto by means of a locking joint. The locking joint comprises locking elements (8), which are brought radially outwards from a position radially inside said sleeve formed end portion (5) and axially outside said annular flange portion (3), such that one part of each locking element (8) is located in an internal recess (7) in the sleeve formed end portion (5), whereas the remaining part of the locking element (8) is located radially inside the periphery of said flange portion 3, whereby the locking element 8 is arranged to transmit axial forces from the first rotor part (1) to the second rotor part (2).

Abstract: At each end the bowl of the centrifuge is journalled for rotation in a bearing housing from which the prevailing bearing loads are transmitted to a support means through a system of springs, the spring rate of which is so low that the natural frequency of the centrifuge is substantially below its normal rpm, preferably lower than 15 percent thereof. The bowl can then rotate at a high rate of rotation without concomitant vibration problems.In order to avoid undesirable transverse forces acting on the bowl a pulley mounted on its protruding shaft end may be pre-loaded in diametrically opposed directions by means of two pretensioned belt drives each of which is trained over a stationarily mounted pulley. At least one of the last mentioned pulleys is driven by a motor.
