摘要： A gas generator comprising a substantially cylindrical gasifier vessel (1), a grate (2) on which solid fuel (8) being combusted is fed, a gasifier throat (6) forming in the gasifier vessel (1) a portion with a cross section narrower than that of the other portion of the gasifier, and gasification air nozzles (4) adapted above the gasifier throat (6) to the gasifier vessel (1). The invention is implemented by way of adapting at the gasifier throat (6), substantially concentric with the center axis of the cylindrical gasifier vessel (1), an upward tapering control element (5) of the gasifier throat cross-sectional area.

摘要： A grate for a gas generator (7) adapted to operate in the gasifier of the gas generator so as to provide support to solid fuel fed thereon such as wood chips, peat, bark and hog fuel from forest harvesting and the like refuse fuel, the cross sections of the gasifier and thus also its grate being substantially circular in shape and the grate being equipped with substantially circular slots (9) having the same center point but a varying radius, whereby the circular slots are formed between the annular grate rings (3), and the grate having placed thereon a mass of balls (2) with a diameter larger than the width of the grate slots. The invention is implemented by way of mounting below the grate a member (4) that is rotatable about the center axis of the grate and is equipped with projections (6), at least some of which extending upward through the circular grate slots (9) to a level higher than the top level of the grate.

摘要： A method for cleaning a pipe (2) carrying a product gas containing impurities, said pipe being substantially rectangular in cross-section. The invention is so implemented that solid and/or liquid impurities are detached from the walls of the pipe (2) and returned into the device (1), such as a gas generator, producing the product gas. The invention also relates to an apparatus implementing the method.

摘要： A seal mechanism for a gate valve (3) operable between a solid fuel feed system (1) and a combustion space (3), such as a gas generator combustion chamber, the fuel feed system comprising a hopper (1) having at least its bottom end portion shaped substantially cylindrical, whereby gate valve (3) controls the discharge opening of the hopper bottom end, and the open/closed positions of the gate valve being controllable by means of a gate valve actuator mechanism (5, 6) in such a fashion that a seal is provided between the bottom end (4) of hopper (1) and gate valve plate (3). The invention is imple­mented by way of providing the lower edge of hopper (1) with a sealing member (4) whose edge facing the gate valve plate (3) is annular and is sharpened substantially over its entire circumferential length.
