241	Apparatus for hot water pressure washer with an automatic burner cool-down	US13969473	2013-08-16	US08960565B2	2015-02-24	Jo Ann Rohner; Robert Rohner
A hot water pressure washer with an automatic burner cool-down includes a water inlet assembly, a low pressure water supply assembly, a coil outlet assembly, a control system, and other related components which are required for the functionality of the pressure washer. A shut-down timer of the control system shut down a power source so that the pressure washer can be automatically shut down through the control system when the pressure washer is not operated. Then a cool-down timer of the control system efficiently cools down a heating coil of a burner assembly. The cool-down timer activates the water inlet assembly, the low pressure water supply assembly and the coil outlet assembly through a pair of solenoid valves in order to cool down the heating coil, where the thermal energy within the heating coil is removed from a phase change of water into water vapor and convection.

243	Water heater with multiple heat exchanging stacks	US13111670	2011-05-19	US08807093B2	2014-08-19	Michael B. Steinhafel
A water heater has a tank having an upper and a lower domes which are penetrated by tubular flues in a 1-1-5 arrangement of a first flue connected to a second flue which in turn is connected to tertiary condensing flues. A gas-fired burner on the upper dome fires into the first flue. Both the first and second flue have heat exchange capacity enhanced by a multiplicity of rectangular metal fins welded in a helical arrangement. Some or all of the fins in the first flue may be stainless steel, while the remaining fins may be a different material, such as mild steel. The first and second flues are arranged to remove approximately 82-89 percent of the heat generated by the burner with minimal or no formation of condensate. Approximately 5.5-9 percent of the heat generated by combustion in the burner is removed in third flues where condensation takes place.

247	Fluidized bed combustion system	US134038	1987-12-17	US4836116A	1989-06-06	G. David M. MacKay; Gordon S. Trivett
A fluidized bed combustion system particularly suited for use in a residential or light industrial heating system comprising a fluidized bed combustor housing a combustion chamber wherein fuel is burned to generate hot flue gas, a heat exchanger disposed inside of the combustion chamber, a particulate collector for removing fine particles entrained in the flue gas before the flue gas is vented to the atmosphere, and a fan for supplying air into the combustion chamber. The combustor features an insulated non-adiabatic combustion chamber with a cooling and heat exchange in the combustion zone and in the free-board area above the combustion zone. Electric heating means are disposed within the fluidizing region of the combuston chamber to provide the capability of heating the slumped bed during shut down to maintain bed temperature above the ignition point. The electric heating means is comprised of rod-shaped electrical resistance heating elements of a commercially available type protruding through the distributor plate into the fluidized bed at a specific inclined position. The control circuitry of the heating elements maintains their surface temperature at a level below about 900.degree. C., preferably below about 750.degree. C. The invention increases operation life of the heating elements by reducing their wear due to corrosion and erosion.
248	Water heater for divers and for other uses	US479994	1983-03-29	US4505254A	1985-03-19	Arthur G. Wigdahl
An unpressurized heater for water or another liquid includes a shell which may be substantially filled with liquid to be heated and within which is immersed a fire box which delivers hot combustion products through fire tubes above the fire box which are themselves surrounded by the liquid contained in the shell. The fire box may be fired by gaseous, liquid or solid fuel. A secondary heat exchanger or heat exchangers within the shell also immersed in the liquid can receive salt water or other fluid which is heated proportionally to the temperature of the liquid in the shell and is circulated through a diver's suit and is ultimately returned to the sea after warming the diver. Back-up heating elements are included for diver applications along with required controls and instrumentation in dry compartments. Built-in fuel storage tanks complete a self-contained system.

250	Rotary heat exchanger	US393571	1973-08-31	US3972203A	1976-08-03	Michael Eskeli
A method and apparatus for transferring heat by employing a rotating centrifuge to compress a gaseous first fluid with accompanying temperature increase and then transferring heat from said first fluid in its compressed state to a second fluid being circulated within said centrifuge in heat exchange relationship with said first fluid. After transferring said heat from said first fluid, said first fluid is allowed to expand within said centrifuge with accompanying temperature reduction. Said first fluid may then be passed out from said centrifuge, or said first fluid may be receiving heat within said centrifuge from a third fluid, being circulated in heat exchange relationship with said first fluid, after which said first fluid is again compressed within said centrifuge. Various gases may be employed as said first fluid, such as air, or halogenated hydrocarbons. Said second fluid is usually a liquid, such as water. The third fluid may also be water.
251	Catalytic fluid heater	US489402	1974-07-17	US3955556A	1976-05-11	Jon B. Pangborn; John C. Sharer
A catalytic fluid heater formed of a number of nested fluid heating chambers spaced from one another to provide therebetween a heating zone having a chimney effect such that a mixture of fuel gas and air is caused to flow through the heating zone from the bottom to the top thereof. A catalyzed surface is disposed in contact with the walls of adjacent ones of the fluid heating chambers. A fuel gas, preferably hydrogen, is delivered to the heating zones, mixed with air and combusted on the catalyzed walls. The combustion product, in such cases, is primarily water vapor, so that external venting is not required.

Electronic solid state control circuitry includes means response to the water level sensed by water level sensing electrode for controlling operation of the feed valve to replace water boiled away thereby maintaining a constant water level in the boiler. The electronic control circuitry also includes current responsive means operative to open the drain valve when the electrode current reaches a predetermined maximum magnitude irrespective of the water level and to close the drain valve when the electrode current falls to a predetermined lower value. The control circuitry includes means to prevent the feed and drain valves from being open simultaneously and electronic hysteresis means to prevent the feed valve from being opened and closed in rapid succession.

Rotation of the one group and variation in the flux causes the conductive member to become heated. A fluid is then directed past the member, in heattransfer relationship with respect thereto, to cause the fluid to be heated and useable as a working fluid.

259	Accessory water heater for a gas-fired water heater	US3793992D	1972-07-26	US3793992A	1974-02-26	MARQUEZ F
An attachment or accessory water heater for mounting on the exhaust gas flue of a gas-fired water heater such as those sold for domestic use. There is usually a considerable space above domestic water heaters as ordinarily installed and the exhaust gas flue of such heaters ordinarily traverses this space. It is proposed by this invention to use much of the heat otherwise dissipated through the exhaust flue to preheat, or superheat, the water. The accessory heater is essentially a heat exchanger conduit of considerable capacity capable of encircling the exhaust flue and having means for connection in series in the piping of the main heater, the conduit having thermal insulation to inhibit loss of heat to the atmosphere.
