摘要： In combustion of gasified fuel by gasifying a low quality fuel and combusting the gasified fuel in a combustor, combustion of gasified fuel is controlled by sampling the gasified fuel at a constant flow rate at the upstream side of the combustor, combusting the sampled gasified fuel, detecting an overall energy level of sensible heat and heating value possessed per unit weight of the gasified fuel on the basis of the combustion temperature of the sampled gasified fuel, and controlling the flow rate of gasified fuel to be led to the combustor in accordance with a fluctuation in the detected overall energy level. Unstable combustion due to a fluctuation in the heating value of the gasified fuel and blow-out due to deficiency of the heating value can be prevented.

摘要： A centrifugal type counterflow contact apparatus having a rotary body or drum intergrally mounted on a rotary shaft, and a plurality of ring members disposed within the rotary body such that circumferential slits are defined between the adjacent ring members in the axial direction of the rotary drum. The ring members have a cross sectional configuration inclined with respect to the axis of the rotary body. A light liquid is introduced into the periphery of the rotary body while a heavy liquid is introduced in the center portion of the rotary body. The heavy and light liquids flow countercurrently through the slits between the ring members under the centrifugal force produced by the rotation of the rotary body, whereby extractability can be improved and accumulation of solids entrained in the feed can be avoided.

摘要： In fuel gasification, particles of, for example, coal and an oxidant are supplied to a reactor, where the coal particles are gasified. The gas thus produced may contain molten slag entrained therein and such slag could subsequently solidify and affect other components of the coal gasification apparatus. Therefore a molten slag cooling heat exchanger is positioned directly above the reactor and this cools the gas so as to cause any molten slag therein to solidify. Hence, such molten slag does not reach an evaporator above the molten slag cooling heat exchanger, so that the efficiency of the evaporator will be maintained. However, solidified molten slag may build up on heat exchange tubes of the molten slag cooling heat exchanger. Therefore, the rate of coolant supplied to the molten slag cooling heat exchanger is varied, to cause expansion and contraction which causes solidified slag to be dislodged. Hence the efficiency of the molten slag cooling heat exchanger does not deteriorate. Cleaning gas and coal particles may be jetted onto the evaporator to dislodge ash or soot therefrom.

摘要： A high temperature, high pressure raw coal gas containing hydrogen sulfide, ammonia, and tarry matter, is purified by contacting the raw coal gas with solid particles thereby cooling the raw coal gas to a temperature suitable for hydrogen sulfide removal and at the same time depositing the tarry matter onto the solid particles by condensation to recover the tarry matter from the raw coal gas, removing the hydrogen sulfide from the cooled and substantially tar-free coal gas, expanding the raw coal gas to a pressure suitable for ammonia decomposition, heating the expanded raw coal gas to a temperature suitable for ammonia decomposition by heat obtained by combusting the recovered tarry matter on the solid particles, thereby regenerating the solid particles for reuse, and then decomposing ammonia in the raw coal gas, thereby removing ammonia therefrom. A process for efficiently purifying raw coal gas by removing tarry matter, hydrogen sulfide and ammonia, including effectively utilizing the recovered tarry matter to produce heat while also effectively utilizing the energy obtained by expanding the coal gas through a pressure-reducing means such as an expansion turbine.

摘要： Nitrogen oxides (NOx) are removed from combustion waste gases by injecting gas (NH.sub.3) into the combustion waste gases in the presence of a metallic catalyst to deoxidize the nitrogen oxides to nitrogen and water, within a reaction tower having the catalysts moving through the reaction tower, so that thereafter the dust may be separated from the catalysts and the catalysts may be regenerated continuously, so that the regenerated catalysts may be returned to the reaction tower. The catalyst moves in a substantially closed path, and preferable downwardly through the reaction tower, with the ammonia gas and combustion waste gases moving in cross current through the reaction tower, with mixing being enhanced by a plurality of angled baffle plates. Regeneration is accomplished by washing the catalysts, particularly ferrous catalysts with water to remove ferric sulfates, thereafter providing ferrous sulfates on the surface of the ferrous catalysts, and thereafter heating the catalysts with combustion gases separate from the ammonia gases, to dry the catalysts prior to their moving into the portion of the reaction tower having therein the mixed ammonia gas and combustion waste gases.

摘要： A contaminant, such as sulfur dioxide, is removed from a fluid, such as hot exhaust gas, by passing it through beds of material for removing the contaminants, such as activated carbon for adsorbing the sulfur dioxide as sulfur trioxide; periodically, the bed is regenerated by discontinuing the passage of process fluid therethrough and passing through the bed a regenerating fluid, such as water, with quantities of the regenerating fluid being successively passed through the bed with corresponding decreasing amounts of contaminants, such as sulfuric acid within the water, in the respective quantities of regenerative fluid. At least one further bed of material is regenerated with substantially the same regenerative fluid in substantially the same succession of concentrations, but out of phase so that a quantity of regenerative fluid of one contaminant concentration is passed completely through only one bed of material prior to its passing through another bed of material. Preferably, after passing through one bed of material, the regenerative fluid is of the next highest concentration and passes through another bed of material in the sequence of the next highest concentration.
