摘要： A method for improving pulp mill steam cycle efficiency includes the steps of providing at least one deaerator tank having a first pressure, and lowering the pressure of said deaerator tank to a second pressure. Feedwater is supplied to a pre-economizer, where it is heated. The water is then delivered to at least one feedwater heater, where it is heated. The water is then delivered to an economizer. By this method boiler steam rate is increased while boiler efficiency is maintained and turbine extraction for deaerator and feedwater heating is minimized.

摘要： A method for positioning superheaters (2, 3, 4, 5) in biomass burning steam generators, and a steam generator. The steam generator comprises a combustion chamber (1), a flue gas duct (6), a steam circuit (7), and the superheaters (2, 3, 4, 5) positioned for minimizing corrosion at a high temperature. The steam generator is fitted with at least two superheaters (2, 3, 4, 5), whose positioning in the flue gas duct (6) and serial arrangement in the steam circuit (7) are effected in such a way that the superheater's or superheaters' heat transfer surface has its surface temperature remaining below the melting point of KOH, 406° C. (corresponds to a steam temperature of about 350-380° C.) down to the point in the flue gas duct (6), at which the flue gases' temperature has fallen to 750° C. While the flue gases are within the range of less than 750° C., the final superheating is effected to a higher temperature without significantly increasing the contamination and corrosion hazard for superheater surfaces.

摘要： In an improved system for recovering heat from a combustion gas produced by burning wastes, the combustion gas or combustible gas produced by partial burning of the wastes subjected to dust filtration in a temperature range of 450-650null C. at a filtration velocity of 1-5 cm/sec under a pressure of from null5 kPa (gage) to 5 MPa before heat recovery is effected. The dust filtration is preferably performed using a filter medium which may or may not support a denitration catalyst. Heat recovery is preferably effected using a steam superheater. The dust-free gas may partly or wholly be reburnt with or without an auxiliary fuel to a sufficiently high temperature to permit heat recovery. The combustion furnace may be a gasifying furnace which, in turn, may be combined with a melting furnace. If desired, the reburning to a higher temperature may be performed under pressure and the obtained hot combustion gas is supplied to a gas turbine to generate electricity, followed by introduction of the exhaust gas from the gas turbine into a steam superheater for further heat recovery. The system can raise the temperature of superheated steam to a sufficient level to enhance the efficiency of power generation without possibility of corrosion of heat transfer pipes by the combustion gas or combustible gas.

摘要： According to the present invention, boiler water is pressurized so that its boiling point is set at approximately 200.degree. C. to 320.degree. C. The boiler water is heated in at least two stages. Thermal energy of gases containing chlorine compounds is used to heat the water to its boiling point. Thermal energy of gases which do not contain chlorine compounds is used to heat the water from its boiling point until superheated steam of a given temperature is generated. The heating which uses the thermal energy of gases containing chlorine compounds is accomplished using the thermal energy from the combustion of pyrolysis gases obtained from a pyrolysis means in which waste material is supplied into a chamber containing a fluidized bed medium which has been heated to at least 300.degree. C., and a pyrolytic reaction is induced. The heating which uses the thermal energy of gases which do not contain chlorine compounds is accomplished using the thermal energy obtained from a char combustion means to combust char in which a char mixture consisting of unpyrolyzed residue and fluidized bed medium removed from the pyrolysis means is fluidized by a stream of air, and the unpyrolyzed residue is combusted.

摘要： A method and system for treating waste liquors from pulping processes for recovering energy and chemicals from the waste liquors (such as kraft black liquor). A recovery boiler having a furnace for combusting waste liquor includes a plurality of injection nozzles in the furnace walls, for injecting waste liquor into the furnace. At least one conduit is disposed in at least one wall of the furnace below the nozzles for withdrawing a portion of the combustible gas from the furnace. Typically between about 10-50% of the combustible gas produced in the furnace is withdrawn through the conduit or conduits below the nozzles, and the withdrawn gas is cooled and purified. The system may utilize a superheater which is separate and distinct from the recovery boiler, the cleaned and cooled withdrawn gas led to the separate superheater.

摘要： A garbage to hydrocarbon fuel conversion system is provided which generates electricity and hydrocarbon gases from combustible garbage. The garbage is pulverized and then burned in a destructive distillation process. The heat produced is used to generate electrical power. Dust precipitated by an electrostatic cottrell precipitator is mixed with light oil and burned in an oil burner. The heat obtained is used to maintain the destructive distillation. The gases which rise to the top of the precipitator are passed through a hydroxide solution which leaves a layer of tar and oil floating on top of the solution and a volume of hydrocarbon gases on top of this layer.
