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 firetube boiler furnace having two combustion sections and an in-line intermediate tubular heat transfer section between the two combustion sections and integral to the pressure vessel. This design provides a staged oxidant combustion apparatus with separate in-line combustion chambers for fuel-rich primary combustion and fuel-lean secondary combustion and sufficient cooling of the combustion products from the primary combustion such that when the secondary combustion oxidant is added in the secondary combustion stage, the NOx formation is less than 5 ppmv at 3% O2.

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 process for fossil fuel refining by contacting ground solid fossil fuel for about 1/2 to about 3 hours with phenol at a temperature of about 600.degree. to 690.degree. F. and a corresponding saturation pressure of about 250 to 430 psig, the phenol being present in greater amounts by weight than the fossil fuel and dissolving refined product from the fossil fuel leaving a solid fuel residue. The phenol containing the refined product is removed from the fuel residue while heated, followed by cooling and separation of the refined product from the phenol which is recycled to the solvent extraction process. The process provides refined products low in mineral matter and sulfur following a low pressure solvent refining process which does not require a proton donor, acid catalyst or an external source of hydrogen.
