Abstract: A reformer (2) which enables rapid load changes of up to 100% within a few seconds, and which is intended to produce hydrogen from hydrocarbons by steam reformation, has an evaporator cooler for cooling the reformate and for generating steam. The evaporator cooler (34) is disposed in the reformer (2), on the end of its reaction vessel. It keeps the applicable end of the tube cool and uses the waste heat of the reformate for generating steam. This makes fast load changes possible, because an increase in the introduction of water immediately causes an increase in the reformate produced and thus an increase in the heat output.

Notably, this control may be performed manually or by way of an automated system. The resulting vessel enhances the safety and performance of the vessel, and it is more easily integrated into a complete fuel processor system. A method for achieving these goals is also described.

Abstract: Production of oxides of nitrogen during combustion of liquid fuel can be reduced by burning at relatively low temperatures of about 1400.degree. C., by first producing a special combustible gaseous mixture of superheated steam, fuel vapor, and combustion air. Water is fed (9) to the apparatus in quantities of about 2 to 4 parts for each part of fuel (10). Then the fuel is vaporized (8) in a stream of the superheated steam. This avoids fuel cracking and formation of long-chain hydrocarbons. Preheated air (13,14,15) is added (17) in slightly over stoichiometric proportions. The resulting mixture is burned (2) and the hot effluent is used to heat the evaporator (6,7,8) and the air preheating chamber (15), with a bypass (20) equipped with a throttle (22) being used for regulation of evaporator temperature. For start-up, an external hot air source (23) or electric heat (24) can be used. The remaining heat in the effluent can be captured in a conventional heat exchanger.

Abstract: An apparatus for treating carbonaceous material, e.g. waste oil by effecting the gasification thereof to produce a relatively high BTU content gas to supplement or substitute for natural gas. This is attained by a furnace in which the products of combustion are utilized to separately generate steam and to preheat a supply of carbonaceous material which may be mixed with water. The generated steam is mixed with the preheated carbonaceous material and passed through a premixing and/or a primary dynamic mixer wherein the preheated carbonaceous material and steam mixture is further heated to a temperature ranging between 1600.degree.-1800.degree. F. to effect a partial gasification of the carbonaceous material. The partially gasified material is thereafter directed through one or more secondary dynamic mixing chambers to be further heated in the presence of additional steam to complete the gasification thereof.
