Reduction Shaft Iron ore, pellets and additives (limestone and dolomite) are continuously charged into the reduction shaft via lock hopper systemEntrained Flow Gasifier | Biofuels AcademyEntrained-flow gasifiers have the ability to handle practically any coal feedstock and produce a clean, tar-free, syngas.The fine coal feed can be fed to the gasifier in either a dry or slurry form. The former uses a lock hopper system, while the latter relies on thePerformance Improvements to a Fast Internally Circulating Fluidized Bed (FICFB) Biomass Gasifier .system was developed, allowing accurate samples to be obtained in a matter of minutes. Experimental testing included a cold testing exercise which provided valuable information on the circulation behaviour of the bed material and char within the gasifier. ThisEnvironmental Expert - Entrained-Flow GasifierThe design allows for 4 hours of continuous feed use at 8 lb/hr before the coal hopper needs to be refilled through a cycling lock hopper. The system may also be fed using coal–water slurry. Pneumatic transport gases consisting of nitrogen or recycled syngas .

Coal Gasification based Production of Direct Reduced .

Dried and ground coal is fed via a lock-hopper into the gasifier, which is fluidized by a mixture of steam and O2. These reactant gases are introduced at the bottom of the gasifier through a distribution grid, and at the ash discharge port in the centre of the distribution grid.15th European Biomass Conference & Exhibition, 7-11 May 2007, .LOCK HOPPER PUMP-1 PUMP-2 Figure 1: Schematic of High Pressure Gasifier The system was equipped with PLC controls and interlocks for operational safety.
