An object of the present invention is to provide a pulverized coal drying system for a pulverizer, a pulverized coal drying method therefor, a pulverized coal drying program, a pulverizer, and an integrated gasification combined cycle capable of stably drying a carbonaceous feedstock irrespective of the type of the carbonaceous feedstock to be used. There is provided a controller (50) of a pulverizer (10) that dries a supplied carbonaceous feedstock by using a drying fluid and includes a flow rate controller that controls the flow rate of the drying fluid within upper and lower limits of the flow rate of the drying fluid that are set to dry a plurality of types or the carbonaceous feedstock having different moisture contents in such a way that the temperature of the drying fluid discharged from the pulverizer (10) approaches a target temperature.

A disulfide oil hydrocarbon stream or a mixture of a disulfide oil hydrocarbon stream and a residual oil is partially oxidized in a gasifier to produce a hot raw synthesis gas containing hydrogen and carbon monoxide which can be passed to a steam generating heat exchanger to cool the hot raw synthesis gas and to produce steam which can be used to generate electricity via a turbine and, optionally, subjecting the cooled synthesis gas to the water/gas shift reaction to produce additional hydrogen and carbon dioxide.

Methods are provided to prepare a low sulfur fuel from hydrocarbon sources, such as light tight oil and high sulfur fuel oil, often less desired by conventional refiners, who split crude into a wide range of differing products and may prefer presence of wide ranges (C3 or C5 to C20 or higher) of hydrocarbons. These fuels can be produced by separating feeds into untreated and treated streams, and then recombining them. Such fuels can also be formulated by combinations of light, middle and heavy range constituents in a selected manner as claimed. Not only low in sulfur, the fuels of this invention are also low in nitrogen and essentially metals free. Fuel use applications include on-board large marine transport vessels but also on-shore for large land based combustion gas turbines, boilers, fired heaters and transport vehicles and trains.

The present invention includes a gasifier for gasifying fuels having a container with a top, sidewalls and a bottom for facilitating the gasifying process. One or more open vertical shafts extend downward inside the container for allowing a downdraft or updraft of air and fuel for the gasifying process. A rotating bed is preferably included inside the container and below the one or more shafts for receiving the fuel. The bed rotates essentially perpendicular to the shaft to facilitate even heating and gasifying of the fuel. The bed is further movable relative to the vertical shaft in order to increase or decrease the volume of fuel flow to the fuel.

Processes for producing high biogenic concentration Fischer-Tropsch liquids derived from the organic fraction of municipal solid wastes (MSW) feedstock that contains a relatively high concentration of biogenic carbon (derived from plants) and a relatively low concentration of non-biogenic carbon (derived from fossil sources) wherein the biogenic content of the Fischer-Tropsch liquids is the same as the biogenic content of the feedstock.

A method of generating syngas as a primary product from renewable feedstock, fossil fuels, or hazardous waste with the use of a cupola. The cupola operates selectably on inductive heat alone, chemically assisted heat, or plasma assisted heat. Additionally, the operation of the cupola is augmented by the use of direct acting carbon or graphite rods that carry electrical current for additional heat generation into the metal bath that is influenced by the inductive element. The method includes the steps of providing a cupola for containing a metal bath; and operating an inductive element to react with the metal bath. Feedstock in the form of a combination of fossil fuel, a hazardous waste, and a hazardous material is supplied to the cupola. A plasma torch operates on the metal bath selectably directly and indirectly. Steam, air, oxygen enriched air, and oxygen are supplied in selectable combinations.

A carbonaceous feedstock gasification power generation facility, and a method for regulating a gas for drying gas this carbonaceous feedstock, are disclosed with which it is possible to expand the range of the types of carbonaceous feedstocks that can be used. High-temperature exhaust gas, low-temperature exhaust gas and extreme high-temperature exhaust gas are bled from the furnace respectively at a high-temperature bleed position, a low-temperature bleed position and an extreme high-temperature bleed position. When these exhaust gases are mixed, the flow volume of the extreme high-temperature exhaust gas supplied to at least one of the exhaust gases, that is, the high-temperature exhaust gas or the low-temperature exhaust gas, is adjusted such that the temperature of at least one of these exhaust gases, that is, the high-temperature exhaust gas or the low-temperature exhaust gas, reaches a prescribed temperature.

The object is to provide a powder fuel feed apparatus, a gasifier unit, and an integrated gasification combined cycle and a control method of a powder fuel feed apparatus that can suppress deformation of a sintered metal filter with simple and inexpensive configuration. An embodiment includes: a distributor pipe (89) in which a mixed gas containing moisture and a gas in which pulverized coal and nitrogen transported with the pulverized coal are mixed is transported; and a diluting nitrogen system (90) that, when a flow velocity of the mixed gas is less than a predetermined threshold, additionally supplies a diluting nitrogen to a mixing chamber (97) connected to the distributor pipe (89) and forming a part of the distributor pipe (89), and the diluting nitrogen system (90) continuously supplies a predetermined flow rate of the diluting nitrogen to the mixing chamber (97).
