摘要:
A flash boiler has a water jacket and a vertically oriented interior passage which includes water tubes or superheating tubes, or both. The interior passage is a hyperboloid surface to induce draft. Water tubes and superheating tubes can be staggered so as to create a helical path for flue gas passing through the boiler. Water tubes and superheating tubes may include, internally or externally or both, heat transfer aids such as pins, fins or vanes, which may also be helicies.

Apparatuses and methods for producing steam are provided. A steam boiler system may include a steam boiler. The steam boiler may comprise an enclosure with a burner, first and second fluid conveyance members, and one or more radiants therein. The burner produces hot combustion gases which warm the fluid conveyance members and thereby the fluid therein. The radiants are also heated by the combustion gases, and they thereby emit radiation which is absorbed by the fluid conveyance members and/or the fluid therein. The boiler system may additionally comprise a steam separator which separates out a steam component. The steam component can be directed back through the enclosure in a third fluid conveyance member to expand the steam before being fed to a steam engine to produce power.
摘要:
A vapor generator, particularly for organic fluids, has a plurality of tubes constituting parallel flow paths. The tubes are wound in interfitted multilayer helices and each tube is of the same length, configuration and flow resistance.
摘要:
An improved heat exchanger apparatus for producing steam or the like wherein a fluid is heated via a burner assembly as the fluid passes through a coil assembly to an outlet steam nozzle, the coil assembly including an outer helically wound coil and an inner helically wound coil generally disposed within the outer helically wound coil and having one end thereof disposed generally near the burner assembly. The coil layers of the outer coil are separated so that the fluid passing therethrough is maintained at a relatively low temperature level with respect to the fluid passing from the inner coil to facilitate the insulation of the coil assembly and to enhance the heat transfer efficiency of the heat exchanger apparatus.
摘要:
A pump connected to a boiler with cylindrical baffles encircled by coils and a heater unit encircled by hot air from the boiler and also surrounded by water heated from the boiler.
摘要:
A portable steam cleaner comprising a wheeled carriage, an enclosure on the forward part of the carriage defining a swirl chamber having a horizontally tangential air input and a vertically axial outlet, a heating coil having spaced convolutions disposed over the chamber such that air passes upwardly therethrough from the chamber, and an oil burner for heating the air which is driven through the swirl chamber and the heating coil by means of a blower. A float valve controlled water supply is disposed toward the upper rear of the carriage along with a soap supply. A hand-held steam gun is disclosed.
摘要:
A steam boiler or analogous heat exchanger is provided with a gas-fired burner comprising a plenum chamber from which a combustible gas-air mixture escapes through an inexpensive and readily replaceable burner member formed of foraminous ceramic material. The porosity and thermal conductivity of the burner member are such as to produce substantially flameless combustion toward the outer surface of the burner member, which causes that surface to incandesce and to radiate heat directly to waterfilled boiler elements facing the burner member.
