| A unit for converting a fossil fuel burning furnace into an electrical furnace for utilization of electrical energy for heating, except under those periods of high energy usage during which the cost of electrical power is high, or during periods when extreme loads exist upon the electrical supply. During such times, a control system is provided to automatically revert the furnace to a fossil fuel burning operation. The unit includes an electrical heating device including a plurality of electrical heating elements arranged in a vertically staggered array for insertion into the ductwork of the fossil fuel burning forced air furnace, such that the elements are in close association to the plenum of the furnace and such that the fan or blower of the furnace provides air flow past such elements.The unit includes a positionally extensible air deflector extending across the plenum in parallel relation to the heating elements such that the air being delivered from the fan or blower of the furnace is properly dispersed past the electrical heating elements prior to delivery through the ductwork.The unit further includes temperature sensing mechanisms to control the fan or blower of the furnace system to control air flow when the electrically heated air reaches a predetermined temperature. A residual heat sensor controls the operation of the electrical heating elements to prevent energization thereof until the residual hot air from the heat exchanger has been dispersed. | ||||||

Access passageways are provided for fuel insertion and ash removal. Boiler tubes supporting the fuel as well as collecting heat from the fire chamber communicate with fluid in the reservoir. Shaker bars interspersed between the boiler tubes supporting the fuel may be actuated to agitate and more completely combust the fuel. | ||||||
| 270 | Heat exchanger | US266020 | 1979-11-08 | US4382425A | 1983-05-10 | Michael Boyes |
| A hot water boiler, particularly for central heating and hot water supply in small dwellings where an economic unit with an output less than about 0.3 megajoule/hr (30,000 but/hr) is required, has a compact, cylindrical heat exchanger (110) with central combustion chamber (20) and forced draught. Water circulates through double-pass longitudinal waterways (12) in the monobloc heat exchanger body (111), in crossflow relationship to hot gases forced through short, narrow, annular radial passages (23). One or more walls (22) separating these passages may be replaced by a hollow wall within which water can circulate, increasing the heat exchange surface available. | ||||||

| An enclosure containing rotating blades for mechanical stirring of gaseous fluids may be a heat exchanger, flue gas energy recovery device, gas generator or combustion device. A high rotational stirring velocity increases the convective heat transfer rate, rendering it independent of the lower throughput velocity of primary fluid which can be controlled independently of the stirring speed. Primary fluid is isolated from a secondary fluid by a thermal transfer surface which is continuously swept by the swirling primary fluid and which may be the peripheral wall of the enclosure or a flow tube located proximate the peripheral wall. In one embodiment, swirling is achieved by radially-extending blade assemblies secured to a rotatable shaft at longitudinally spaced locations to establish discrete swirling zones in which fluid recirculates from the shaft outwardly, along the wall, and back toward the shaft. In another embodiment, the blades extend longitudinally, proximate the peripheral wall, from peripheries of horizontal discs which rotate with the shaft. In this embodiment, primary fluid follows a restricted helical path, maintaining continuous contact with the thermal transfer surface, away from the shaft. Either embodiment may be converted to a combustion system by igniting primary fluid in the presence of admitted air. In all embodiments, recirculation of primary fluid condensate, injected water or additive optimizes heat transfer via latent heat of vaporization and dropwise condensation. Blade rotary speed may be varied to commonly or independently control: combustion fuel and air flow; primary fluid flow; and stirring energy. | ||||||

| 274 | 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.
