The gasifier is fed with a slurry of kg of water per kg of solids, produced by wet grinding Illinois #6 coal (Table 2) in an open circuit rod mill with slag fines recycled from the gasifier and preheated water.
Some manufacturers however, use a radial inflow design. The radial inflow turbine is rugged, less complex, less expensive and easier to manufacture than the axialflow turbine. This radial flow turbine design is a "backwards" version of the centrifugal flow compressor.
Feb 01, 2018· Gasification of black liquor. DOEpatents. Kohl, Arthur L. . A concentrated aqueous black liquor containing carbonaceous material and alkali metal sulfur compounds is treated in a gasifier vessel containing a relatively shallow molten salt pool at its bottom to form a combustible gas and a sulfiderich melt.

The authors report: "This gasifier is a pressurized, entrainedflow gasifier that has a capacity of x lO^gOOO pounds) of coal per hour,and has a down flow configura tion with some similarity to an entrained flow gasifier operated by the Bureau of Mines during the period .
Normally in solving problems involving turbines, the turbine efficiency is known from manufacturers tests, and the inlet state and the exhaust pressure are specified. State 1 and p2 determine the isentropic discharge state 2s using the steam tables.
Another potential route for sludge disposal is to direct it to a steelmanufacturing company, where the CaF, can be used as a neutral flux to lower the slagmelting tem ' ! perature and to improve slag fluidity.
50 Clean coal technologies for power generation Since natural gas is a versatile fuel that can be used for many purposes, the factors driving these increases in demand vary by region.
The sidewall of the Shell gasifier is water cooled, which causes the molten slag to form a thin solid film over the gasifier refractory liner, protecting it from corrosive Because a watercooled liner is used, refractory replacement occurs within 5 to 8 years, and thermocouple replacement about once a .
During slag collection, the slag continuously falls into the lockhopper. When it reaches a preset time, a slag discharge procedure will be initiated to discharge the slag. The lockhopper sequence has a cycle of 30min, the collection and dump are about 28min and 2min respectively.
