Abstract: A blower burner is provided for a boiler heated with fluid fuels with a blower casing, which incorporates on one side the blower with the attached drive motor and where the fire tube of the burner comes out on the other side. The motor and the fire tube form protruding parts on opposite sides of the blower housing. The rear side of the fire tube protrudes beyond the side of the casing disposed toward the drive motor and the rear side of the fire tube protrudes into a cover extension attachment of the blower casing. The burner is provided with a pressure controller, where the air pressure inside of the fire tube element is measured by the input sensor signal and where the blower speed is the variable controlled by the pressure controller. Furthermore, a sound absorbing means is provided for the blower burner.

Abstract: Cooling rods (2) take away the heat from the flame area of a burner (1). Various embodiments of supports (4) for these cooling rods (2) are disclosed.

Abstract: A gas burner comprising a heating gas pipe, the wall of which is traversed by at least one group of longitudinally arranged outlet nozzles. These groups of nozzles (2 or 3) are connected with at least one conduit (5) for a heat accumulating agent which is parallel to the heating gas pipe (1).

Abstract: A system is provided for generation of a set point for a control or automatic feed back control of the feed line temperature in a heating plant depending on the outside temperature. Usually such set points are entered as heating curves into the controller. The heating curves are in reality nonlinear relationships and are difficult to be processed by a computer. The invention subdivides the heating curve into two straight lines, which meet at a common point. This point is placed where the maximum difference occurs between the heating curve and a linear relationship connecting points corresponding to a minimum permissible lowest temperature and to a sufficient high outside where no heating energy is required. Operation according to the invention saves energy by better approximating the temperature requirements of inside rooms at different outside temperatures and this increases the comfort of the persons staying there.

Abstract: A system for controlling a sorption heat pump. Fuel is fed to a burner via a feed line and a fuel valve. The burner heats a generator containing a heat transfer fluid such as a mixture of water and ammonia and generates pressure inside the generator. The vapors produced by the heating are condensed in a condenser. The condensed heat transfer fluid vapors are throttled and passed into an evaporator. The output fluid from the evaporator is returned via an absorber to the generator. Heat is exchanged between the fluid and a circulating medium for a thermal use provision in the condenser and in the absorber. An intensive thermodynamic parameter such as pressure or temperature of the fluid in the pressurized section of the sorption heat pump is controlled depending on the heat requirements of the thermal use provision and/or the thermal input from the environment into the evaporator. The generator and condenser can be constructed as a joint unit preferably with an intermediate rectifying column.

Abstract: A system is provided for igniting and monitoring a fuel burning heat source which comprises a thermoelectric safety burner valve, a thermocouple to be heated by a pilot burner, a fuel source feeding fuel to a pilot feed valve and to a main burner feed valve, which in turn are connected to the pilot burner and respectively the main burner. An electric supply source is provided for energizing either an ignition voltage generator or a thermostat simulator. The igniting and monitoring system can be operated electrically or otherwise manually regardless of the state of the electric supply source. A manually operable pilot fuel valve is connected in parallel to the electrically actuated pilot fuel valve and is connected with a switch for disconnecting the electric supply voltage. Thus the heat source can be operated manually in cases where the electrical supply source is not available without impairing the generation of heat.

Abstract: The present invention relates to a method of determining the set point of a pressure and temperature controller for the high-pressure part of a sorption heat pump.Since the manufacturer of sorption heat pumps does not know from the outset at which location the heat pump is to be installed, such heat pumps cannot be preadjusted, but must be adjusted individually at the location of installation in accordance with the requirements of the user and the expected outdoor temperature.It is the object of the present invention to provide possibilities for preadjusting the temperature and pressure controllers of sorption heat pumps to values which are subsequently varied only in dependence on the day-to-day operating conditions.

Abstract: A sorption heat pump including a fuel energized discharge unit from which heated fluid media for the heat pump is provided and a circuit having the fluid media circulated therethrough and arranged to include a heat exchanger, an absorber, pump devices, a temperature level changer and an energy consumption circuit. The discharge unit operates to emit the fluid media into the circuit as a heated weak solution and to receive the fluid media returned from the circuit as a rich solution. The discharge unit also produces an overheated vapor. The temperature level changer comprises a first and a second heat exchange unit, with the first unit being directly connected to the discharge unit to receive the weak solution therefrom, with the first unit also being connected to form part of a supply line for the energy consumption circuit.
