GASIFICATION APPARATUS

A combined fluidised bed (FB) and fixed bed (UB) gasifier in which the fixed bed gasifier is arranged in the path of the effluent gases from the fluidised bed gasifier. The fixed bed fuel (coal) acts as a filter for the entrained particles, char, ash etc. from the fluidised bed and in return the effluent gases devolatilise the fixed bed fuel. The latter is thus broken down and falls, or is driven, into the fluidised bed. The fixed bed (UB) may be arranged either (Fig. 1) directly above the fluidised bed (FB) or (Fig. 5) in an adjacent duct (27) from which it has to be driven up before falling into the fluidised bed.

Over at least part of the fluidized bed height, the gasifier has a horizontal cross-section, which has different dimensions in two directions perpendicular to one another. The nozzles can project by different amounts into the gasifier vessel.

Device for generating combustible product gas from carbonaceous feedstocks

A device is provided for generating combustible product gas from carbonaceous feedstocks through allothermal steam gasification in a pressurized gasification vessel. The pressurized allothermal steam gasification of carbonaceous fuels requires that heat be supplied to the gasification chamber at a temperature level of approximately 800-900 °C. In a heat pipe reformer, as is known from EP 1 187 892 B1, combustible gas is generated from the carbonaceous feedstocks to be gasified through allothermal steam gasification in a pressurized fluidized bed gasification chamber. The heat needed for this is fed to the gasifier or reformer from a fluidized bed combustion system through a heat pipe arrangement. Due to the straight and tubular construction of heat pipes, the combustion chamber and reformer/gasification chamber are disposed one above the other in the known heat pipe reformer from EP 1 187 892 B1. The pressure vessel base is under particular stresses due to the high temperatures in the combustion chamber. In addition, the base is weakened by a plurality of heat pipe feedthroughs. The sealing of the feedthroughs also presents a problem. In conventional tubular heat pipes, the line for liquid heat transfer medium and for gaseous heat transfer medium are both disposed in the common tubular shell. The fact that the present invention uses loop heat pipes in which the liquid heat transfer medium is conveyed spatially separated from the gaseous heat transfer medium allows the number of feedthroughs to be reduced to two, namely a liquid line and a vapor line. When a plurality of such loop heat pipes is used, the separate vapor and fluid lines thereof can be combined in the gasification pressure vessel to form a common vapor and liquid line, which then penetrate the gasification pressure vessel. Outside the gasification pressure vessel, the two common lines can then be separated again. This allows the number of feedthroughs from and into the gasification pressure vessel to be ...

Feedstock inlets are configured to introduce the reactive material into a region that is vertically between the first and second clusters of heating conduits. The heating conduits in the first cluster have a first thickness while the heating conduits in the second cluster have a second thickness. The first separation distance is at least as great as the smaller of the first and second thicknesses.

Indirectly heated thermochemical reactor apparatus and processes

Resonant tubes of a pulse combustor are immersed in a bed of solid particles in a reaction zone to provide indirect heat from the pulsating combustion gases to the solid particles of the bed. The bed is maintained in an agitated state by a gas or vapor flowing through the bed. Reactant materials are introduced into the agitated bed and undergo reaction at enhanced rates resulting from heat transfer coefficients at least about twice as high as those of steady flow combustors and an intense acoustic pressure level propagated from the pulsating combustor into the reaction zone. The apparatus is useful, for example, to steam reform heavy hydrocarbons and to gasify carbonaceous material, including biomass and black liquor to produce combustible gas at relatively low temperatures, with steam being usilized as the bed fluidizing medium. Black liquor gasification, utilizing sodium carbonate as bed solids, results in liquor energy and chemical content recovery without smelt production.

A fluidized bed system in use with independent combustor

The present invention relates to a fluidized bed indirect gasification system with an independent combustor which enables to obtain high quality of synthetic gas through effective indirect gasification of low grade fuels having various constellations such as biomass, waste, coal, etc. According to the present invention, the system comprises a pre-process unit having a selector (500); a gasifier (300) supplied with a first fuel selected in the pre-process unit; a combustor (100) supplied with a second fuel selected in the pre-process unit; and a riser (200) for connecting the gasifier (300) and the combustor (100) and having temperature-increasing and transporting functions of a bed material therein.

Fluidized bed apparatus

A fluidized bed apparatus having an outer vessel provided at a lower region with a plenum chamber as well as a grid situated directly above the plenum chamber and carrying a plurality of nozzles through which gas flows from the plenum chamber into the space in the vessel above the grid. These nozzles provide a given pressure drop in the gas flowing therethrough while as the gas flows from the plenum chamber through each nozzle there is also provided by way of a suitable structure a preliminary pressure drop, so that a two-stage pressure drop is provided in the gas flowing through each nozzle from the plenum chamber into the vessel above the grid. In this way it is possible to achieve a flow of gas above the grid sufficient to maintain the particles suspended in the fluidized bed while attrition of the particles is maintained at a minimum so that very little if any fines flow out of the vessel with gas which is formed therein. According to this method, the particles are petroleum coke particles while the gas is a mixture of steam and air maintained in the plenum chamber at a pressure of only 1-5 psig above the pressure in the bed while at the region of the interior of the vessel above the grid the temperature is on the order of 1500°-1800° F. The grid supporting the nozzles is sloped 3° to 5° downwards towards a center well and supporting member to allow solid agglomerations such as lumps of coke and slag to move radially inward into the well for withdrawal.
