    摘要: A heating system having a steam generator or water heater, at least one economizer, at least one condenser and at least one oxidant heater arranged in a manner so as to reduce the temperature and humidity of the exhaust gas (flue gas) stream and recover a major portion of the associated sensible and latent heat. The recovered heat is returned to the steam generator or water heater so as to increase the quantity of steam generated or water heated per quantity of fuel consumed. In addition, a portion of the water vapor produced by combustion of fuel is reclaimed for use as feed water, thereby reducing the make-up water requirement for the system.

    摘要: A multi-stage heating apparatus having a first stage combustion chamber, a second stage combustion chamber, a primary porous matrix chamber disposed between the first and second stage combustion chambers, a secondary porous matrix chamber, heat exchanger tubes for transfer of heat from the combustion products to a working fluid, a recirculation device for recirculating combustion products in the first and second stage combustion chambers to the root of flames therein. A mixture of fuel and primary oxidant is introduced into the first stage combustion chamber, and the products of combustion therein are conveyed to the porous matrix chamber disposed between the first and second stage combustion chambers. After undergoing intensive heat transfer in the porous matrix chamber, the cooler products of combustion flow into the second stage combustion chamber forming additional products of combustion. The products of combustion then flow to a second porous matrix chamber in which they undergo further intensive heat transfer. From there, the products of combustion pass through an economizer for preheating a working fluid and through a condenser for removing moisture in the combustion products prior to being exhausted.

    摘要: A method for removing a condensable component from a process stream in which a first side of a permselective membrane is contacted with the process stream in which is disposed the condensable component. The condensable component is passed through the permselective membrane to a second side of the permselective membrane, forming a condensable permeate. The condensable permeate is then contacted with a liquid stream having a liquid form of the condensable permeate, forming a condensed permeate. The condensed permeate may then be returned to the process which generated the process stream.

    摘要: A method and apparatus for combustion of a solid carbonaceous material in which the solid carbonaceous material is preheated and at least a portion thereof pyrolyzed on a stoker grate disposed in the lower portion of a combustion chamber to produce pyrolysis products. Overfire oxidant is then introduced into the combustion chamber above the stoker grate to ensure complete combustion of combustibles in the products of combustion generated by combustion of the solid carbonaceous material and the pyrolysis products. Preheating and pyrolysis of the solid carbonaceous material is carried out by the introduction of a pyrolysis agent directly into the bed of solid carbonaceous material.
