| 221 | Wood fuel heating apparatus and combustion process | US292691 | 1981-08-13 | US4479481A | 1984-10-30 | Charles S. Ingersoll; E. Peter Schellens |
| A boiler having a downdraft solid fuel firebox with a refractory hearth structure with a plurality of parallel internal conduits forming an internal combustion chamber, a heat exchanger below the firebox connected to the outlet of the internal combustion chamber, an outlet blower connected to the outlet of the heat exchanger and an air inlet valve controllable with the outlet blower to control the induction of air through the boiler for automatic boiler control. | ||||||
| 222 | Liquid heating system | US342730 | 1982-01-26 | US4471724A | 1984-09-18 | William T. Pope |
| This invention is a non-fossil fuel fired hot water system which allows a large amount of water or other liquid to be raised to a relatively high temperature, but below the boiling point, in a relatively short period of time. Due to a unique air circulation system, extremely high temperatures of the combustible material can be obtained with secondary burning eliminating all visible particulate material from the exhaust stack of the system. The unique firebox itself is disposed such that it is surrounded by water on all sides including the access closures for said firebox. | ||||||
| 223 | Stove | US401946 | 1982-07-26 | US4419942A | 1983-12-13 | Charles A. Johnson |
| A stove in which the fuel is combusted within a primary combustion zone and the products of combustion are transported into a tertiary combustion zone surrounded by a container of water. A bundle of secondary combustion tubes connect the primary and tertiary combustion zones. The tertiary combustion and separation chamber termed a posatron completes the combustion and separates a portion of the creosote and other condensable materials from the combustion gases. The combustion gases are then conducted through small pipes immersed in the water bath to cool the combustion gases and complete the condensation of water, creosote and other unburned constituents. The water and creosote mixture flows into a creosote collection chamber and the products of combustion are either recycled to the combustion chamber or exhaused to the atmosphere. Heat is removed from the system by recirculating air or by hot water circulation. | ||||||
| 224 | Heating boiler | US359668 | 1982-03-08 | US4408547A | 1983-10-11 | Ilpo Autere |
| The invention concerns a heating boiler operating on solid, comparatively finely divided fuel, such as chips or peat, and which is used to produce hot water or steam. The boiler comprises a furnace, in which the grate consists of a shell-like burning basket, which can be placed in rotary motion about its substantially horizontal axis. The rotating of the burning basket may be arranged by connecting to the basket a tubular arm provided with a gear wheel and which is connected to a motor placed outside the boiler. The arm then simultaneously serves as duct through which the fuel is introduced into the burning basket. The purpose of the rotating burning basket is to boost the combustion reaction so that comparatively wet fuel can be used in the boiler. The combustion may furthermore be boosted by placing the burning basket in the furnace in a housing having as its extension a cyclone constituting a helical exhaust duct for the flue gases, which sets the gases at high temperature into strongly turbulent motion. | ||||||
| 225 | Combustion apparatus | US265596 | 1981-05-20 | US4394839A | 1983-07-26 | Ikeda Toshio |
| A combustion apparatus and a process used to obtain hot water without producing any pollution therefrom, including a hermetic casing, a furnace and cyclone device, all of which are disposed in the hermetic casing. The furnace being designed to combust a waste material and the exhaust gases including dust being introduced into the cyclone device to eliminate the dust. The hot water is obtained by surrounding the furnace and cyclone device with a space including water which contacts directly to the heated walls thereof. | ||||||
| 226 | Multi-fueled boiler | US252254 | 1981-04-08 | US4393814A | 1983-07-19 | Raymond Sievert |
| An improved multi-fueled hot water or steam boiler comprising a plurality of compartments, one compartment for the combustion of a solid fuel, such as wood or coal, and the other for the combustion of a liquid fuel and separated from each other and the exterior of the boiler by water-conducting walls; a water supply tank positioned above one of the compartments and connected to the water-conductive walls; and a plurality of horizontal fire tubes passing through the water supply tank and connecting one compartment to an exhaust flue. The compartment not positioned below the water supply tank has a water-conductive ceiling slanted upwardly toward and connected to the water supply tank. One compartment has an adjustable air-flow secondary damper in addition to a primary air damper. The water-conductive walls, fire tubes, adjustable secondary damper, and upwardly slanting water-conductive ceiling reduce boiler heat losses and improve boiler efficiency. | ||||||
| 227 | Multi-zone boiler for firing with solid and liquid fuel | US212733 | 1980-11-05 | US4367697A | 1983-01-11 | Karl Ackerman |
| A furnace for alternatively burning solid or liquid fuels is disclosed. The furnace includes an oil burner and a solid fuel burner as well as a combustion chamber for the burning fuel. The hot combustion gases can be introduced through one of two sets of chimney gas flues, depending upon the fuel being burned. A tiltable flap at the inlet of the chimney gas flues controls which set of flues the gas passes through. At the outlet of the flues, a reversing chamber reverses the direction of the gases and directs them to a flue gas pipe for removing the combustion gases from the furnace. The position of the tiltable flap is controlled by a control means responsive to the sensed temperature of the gas leaving the furnace. The chimney gas flues define a heat exchanger and may be formed from flat plates or round ducts. | ||||||
| 228 | Furnace | US92550 | 1979-11-08 | US4292933A | 1981-10-06 | Daniel Meier; Carl Maendel |
| A furnace with a combustion compartment and a heat exchanger compartment connected by a channel having a secondary air inlet for efficiently burning wood and absorbing the heat of combustion. | ||||||
| 229 | Water heating stove | US972224 | 1978-12-22 | US4226195A | 1980-10-07 | Martii K. Lindroos |
| A water heating stove, comprises a fire box substantially surrounded by a water jacket through which water to be heated circulates. The fire box is completely closed by sealing, loading and clean out doors, to provide that the only access for combustion air is a special aperture below the fire, controlled by a thermostatically operated damper. The fire box bottom wall is inclined to allow drainage of water condensates without losing combustion air flow control, via a water trap. The stove includes a heat transfer coil through which water is circulated to supply hot water. | ||||||
