    The purpose of the Wicks Efficient Fuel Utilization System (WEFUS) is to produce electric energy and heat simultaneously in a fuel conserving and cost effective manner. WEFUS is a new and novel system that combines the fuel conserving technique of cogeneration with the fuel conserving technique of condensing heating so that the resulting combined system has an additional fuel conservation benefit relative to a system that uses only one of these fuel conserving techniques. The internal components are all conventional and include an internal combustion engine (15), an electric induction machine (17), a fan (18), a high temperature heat exchanger (20), a low temperature condensing heat exchanger (21), along with a controller (14), that controls the position of a solenoid controlled fuel valve (11) and a solenoid controlled electric breaker (13) in response to a signal from a thermostat (27) and conditional to signals from an electric power sensor (25) and unsafe condition sensors. WEFUS also has some inherent safety advantage relative to conventional furnaces since there is no large combustion chamber and additional safety advantages result from conditions that are sensed and input to the controller which then isolates the system from the fuel and electric power connections if an unsafe condition is sensed.

    The system works as follows.
    The cold air is sucked in the direction of arrow 6a, inside module 1 by fan 20 through channel 2, filter 4 passes, muffler 31 and enters the condenser cooler 22 by cooling. heating and then arrows 6c and 6d are supplied to the engine 12, the silencer and the non-condensing heat exchanger 21, cooling these elements and heating up successively. The heated air through the muffler 32 and the filter 5 nq to the channel 3 is supplied to the heated room.
    The relative movement of air and exhaust gases is organized in such a way that after exhaust from the engine, the gases are first cooled by air, which is already heated by the heat of the generator and the engine. Heating the air with heat from the gases discharged from the engine allows it to maximize its temperature before it enters the heated space. Partially cooled spent gases enter the condensation chiller 22, which is installed along the air flow ahead of the engine and generator. Air blowing at the lowest temperature enters it. As a result, the exhaust gases are cooled in it to a dew point and additionally give off the heat of phase transformation to the heated air. To organize the movement of condensed and non-condensed products, this heat exchanger is made with a downward flow.

    A thermostat 26 is installed in the heated air flow in the room; it is connected to the control unit. Depending on the thermostat signal, the control moves the switch to the on or off position, i.e. to turn the fan on or off. At the same time, the amount of electricity supplied to the power supply system depends on whether or not the motor is turned on for driving the fan. On the coldest days, heat is needed for heating the air more and, consequently, the engine operation time increases, the amount of energy produced by the generator increases accordingly, and this corresponds to the peak winter load of the power supply system.
    The purpose of the control body is not only to turn the system on and off in response to a control signal from the thermostat, but also to turn off the system when dangerous conditions are detected or equipment fails. Thus, the device status can be defined as Enabled (operating mode), Disabled (able to work, but does not work, because heat is not required) and Disabled (idle mode due to the detection of dangerous conditions or failure). In normal mode, the system automatically cycles from On to Off. Switching from the Disabled state to the Disabled or Enabled state is possible only by pressing the Return button after determining the causes of the Disabled state.
    After receiving the signal turned on from the thermostat, the control unit that is in the Off state turns on the power supply to the solenoids of the fuel valve and the electrical contactor, opening the valve and closing the contacts between the forced air supply and heating system and the power supply system. Since the generator is made in the form of an electric asynchronous machine, this machine starts to work as a starter for the engine and drives the motor shaft at a speed slightly lower than the synchronous speed. A rotating engine receives a fuel-air mixture and begins to generate mechanical energy, rotating an asynchronous machine, which goes into asynchronous generator mode at a rate slightly higher than synchronous. A fan mounted on the shaft drives the room air through the air cooling system of the engine and the generator, the silencer, the non-condensing heat exchanger and the condensation cooler of exhaust gases. When a signal is received from the thermostat to the control unit. The control unit is turned off and turns off the power supply to the solenoids, closing the fuel valve and opening the electrical contacts.
    The control generates a signal that is turned off when there are dangerous conditions, for example, if the gas level exceeds a specified level, and also when it detects

    Failure of equipment failure, i.e. if the output power after a normal start-up period is below a predetermined normal level to which the control device is tuned. / The fact of power reduction is used as a signal of equipment failure because, with almost any electrical and mechanical failure, the output power decreases as compared to normal. The delay for the normal start-up period after the issuance of the On signal before the Disable signal is issued when the power drops below normal is necessary for the flow, that an asynchronous machine in starter mode consumes power, i.e. creates a negative flow of power.
    The design of the control unit that implements the functions Enabled, Disabled, Disabled requires the use of two high-speed relays and one time relay (or in another embodiment, the logic of the control unit can be programmed on a solid-state circuit). One of the high-speed relays is triggered in response to the signal from the failure sensor, and the other high-speed relay and the time relays are triggered in response to the signal from the power sensor of the asynchronous machine. The control supplies power from the power supply system on the supply side of the contactor, when the power supply is turned off, the control switches to the Disconnected state.
    Thus, the implementation of the control body ensures high reliability of the system.
    The exhaust gas condensation cooler must provide heat removal from the exhaust gases in the low-temperature range and be corrosion resistant, since condensate may contain large amounts of acid. Materials suitable for its manufacture are stainless steel and teflon-coated steel. The need for a downward flow is due to the fact that the condensate must be drained in the direction of flow. In order to maximize heat transfer and heat extraction, it is necessary to direct exhaust gases in countercurrent to the supplied cold air. Gases from the engine injection- | Forcibly, which allows the s-to shorten the time of exposure of the condensate to materials and localize the condensate in certain zones. The main acid present in the condensate can be hydrochloric acid, which can be used as a source for household cleaners, water, and structural materials. Therefore, the air used in the combustion reaction should be supplied directly from the atmosphere. The use of outside air also reduces the heat consumption for heating the room.
    Cooling the exhaust gases to the Condensation Temperature of the 4 water vapor contained in them allows the heat of condensation to be used to preheat the air, which increases the efficiency of the system.
