Abstract: This invention provides an electronic control for combination (fuel-fired boiler and electric heat pump) building space and water heating systems that optimizes operation of such within the operating temperature limits and heat capability of both the heat pump and boiler unit in the combination system. In a diagnostic mode, the controller assesses the ability of existing heat radiation systems in thermostatically controlled zones to meet heating loads at different operating temperature limits of the heat pump and boiler. The system/controller provides information to guide most effective deployment of system heat-dissipation devices. In its normal operating mode, the controller is capable of receiving input signals from zone thermostats, the boiler and heat pump, along with current outdoor temperature and other data, processing and evaluating inputs over time, and outputting control signals.

Abstract: The present application overcomes the disadvantages of the prior art by providing a system for proper life-cycle management of plastic products and the plastic waste that plastic products produce.

Abstract: This invention provides a system or method that includes combustion of mixed content solid waste to produce flue gases and separation of carbon dioxide gas in the produced combustion flue gas from other gaseous constituents of the flue gas in an amount produced from the burning of plastic material contained in the mixed content solid waste. The separated carbon dioxide is sequestered in geologic formations, thereby providing environmentally sound disposal and elimination of plastic waste, in one consolidated process, free of the need for separation of plastic waste from other solid or the need to identify and separate the various forms and compositions of plastic waste material. The illustrative disposal of plastic waste hereby is generally free of emission into the atmosphere of carbon dioxide gas. The invention includes a fee-generation process applied to customers, which can quantified and generated in association with the application of the system or method.

Abstract: This invention provides a system and method for cogeneration of electric power and building heat that efficiently interfaces a liquid-cooled electric power generator with a multi-zone forced hot water (hydronic) space heating system. The system and method utilizes an electric generator with an electric output capacity (kW) that is near the time-averaged electric power consumption rate for the building and with a heat generation capacity that is useful for meeting building heating needs. This generator is operated as the priority source of heat for the building, but normally only when there is a demand for heat in building, with the intent of running the generator for long periods of time and generating a total amount of electric energy (kWhs) that is significant in comparison to the total electric energy consumption of the building over time.

Abstract: This invention provides a system and method for cogeneration of building heat and electric power and that efficiently interfaces a warm air heating system with a liquid-cooled electric power generator. The system and method utilizes an electric generator that is rated at near the time-averaged electric power consumption for the building. This generator is operated as the priority source of heat for the building, but normally only when there is a demand for heat in building. In this manner, the generator can run to generate a significant part of the building's electric power but in a manner that is typically supplemented in variable quantities by power from a public power grid. The heat output is directed via a liquid coolant circuit on the generator, as needed, to the warm air heating unit for the building. The warm air heating unit blows return air through a cabinet and out to the supply duct(s). The warm liquid coolant is directed through a primary heat exchanger in the cabinet.

Abstract: A small-scale, space-heating and electrical power co-generation system includes a heater and a pump for supplying high-pressure water to the heater. Within the heater, the high-pressure water is heated to at or near its saturation or boiling point so as to produce both vapor (e.g., steam) and liquid (e.g., water) fractions. This high pressure, two-phase mixture is then provided to an expander which expands the two-phase mixture to a lower pressure and, in the process, produces mechanical energy. The expander is coupled to an electrical generator so that the extracted mechanical energy can be used to drive the generator and thus produce electrical power. The fluid exiting the expander is then provided to a condenser. A space heating fluid (e.g., air or a separate water supply) is brought into proximity with the condenser so that it may be heated. This space heating fluid is then be distributed throughout the corresponding home or building for space heating purposes.

Abstract: A self-powered heating system includes a boiler for generating steam, an expander for extracting mechanical and electrical energy from the steam and a heat exchanger for transferring heat energy from the steam to room air. A fan mounted adjacent to the heat exchanger forces room air to be heated past the heat exchanger and through the space being heated. An electric pump returns condensate from the heat exchanger to the boiler. The mechanical and electrical power for operating the fan and pump are provided by the expander. In particular, the expander extracts mechanical energy from the low pressure steam supplied by the boiler to power the fan and includes a magneto for generating an alternating current which may be converted to a direct current for powering the pump. The electrical power generated by the magneto is also sufficient to power a steam valve to the expander and a fuel valve regulating fuel flow to the burner.

Abstract: A self-powered, forced hot air space heating system including a boiler for generating steam, a mechanical power producing steam expander, and a heat exchanger for heating air. Steam from the boiler is supplied to the expander and the heat exchanger, which is disposed in close proximity to the boiler. A fan powered by the expander is mounted adjacent to the heat exchanger in order to force air to be heated past the heat exchanger and through the space being heated. By operation of the fan, cool air is forced past the heat exchanger and heated. The resulting warm air is then provided to the space being heated. The system provides central forced hot air heating without the need for any external supply of electrical power. In another embodiment, a hot water heater is used in place of the boiler to heat high pressure water. The high pressure hot water is expanded to obtain mechanical energy for driving a generator and, thereby, producing a supply of electrical power.

Abstract: A forced hot-water heating system in which sensible and latent heat remaining in flue gases after contact with a primary heat exchanger is recycled into incoming cold air by a second heat exchanger. The heater, humidified intake air is then directed to a fuel burner, and reduces the amount of fuel necessary to achieve a given amount of heat exchange at the primary heat exchanger at normal operating return-water temperatures.
