Abstract: A propellant flow actuated piezoelectric igniter device using one or more hammer balls retained by one or more magnets, or other retaining method, until sufficient fluid pressure is achieved to release and accelerate the hammer ball, such that it impacts a piezoelectric crystal to produce an ignition spark. Certain preferred embodiments provide a means for repetitively capturing and releasing the hammer ball after it impacts one or more piezoelectric crystals, thereby oscillating and producing multiple, repetitive ignition sparks. Furthermore, an embodiment is presented for which oscillation of the hammer ball and repetitive impact to the piezoelectric crystal is maintained without the need for a magnet or other retaining mechanism to achieve this oscillating impact process.

Abstract: A combustion apparatus includes a fuel supply line for providing an overall fuel supply to the apparatus; a burner including multiple fuel supply lines, the supply of fuel in the fuel supply lines to the burner corresponding to the overall fuel supply in the fuel supply line to the apparatus, and a combustion volume associated with the at least one burner. A temperature sensor measures a temperature of a part of the apparatus to be protected against overheating. A pressure sensor measures pressure within the combustion volume. A control arrangement varies the fuel supplies to the burner based on the measured temperature and pressure and on an information indicative for a progress over time for a signal for a time span. The arrangement maintains the temperature of part to be protected and the pressure variations within the combustion volume below predetermined limits, while maintaining constant fuel supply to the apparatus.

Abstract: A system and method for providing real time control of a heliostat array or CPV/PV module that reduces actuation cost, the disclosure reduces the fixed cost of calibrating and repositioning an individual surface. This simultaneously removes the core engineering assumption that drives the development of large trackers, and enables a system and method to cost effectively track a small surface. In addition to lower initial capital cost, a small heliostat or solar tracker can be pre-assembled, mass-produced, and shipped more easily. Smaller mechanisms can also be installed with simple hand tools and do not require installers to rent expensive cranes or installation equipment.

Abstract: A furnace is disclosed that includes a burner with a firing rate that is variable between a minimum and a maximum firing rate. After a call for heat is received, the firing rate is set to an initial level above the minimum firing rate, and the burner is ignited. The firing rate is then modulated downward toward the minimum firing rate. If the flame is lost during or after modulation, the burner is reignited and the firing rate is maintained above the firing rate at which the flame was lost until the current call for heat is satisfied. In some cases, the firing rate is maintained until one or more subsequent calls for heat are satisfied.

Abstract: A dryer for drying objects of material has a container-like body. The body is substantially tight and material to be dried can be fed into it. The body may be substantially upright or inclined. The material to be dried is fed at the lower part of the body is discharged from the upper part thereof and drying gas is directed to the dryer substantially at the upper part of the body and taken off from the lower part thereof. This is achieved by shut-off arrangements of the feeding and discharge of the material to be dried and by the structure of the body. The drying gas circulates in the dryer in a substantially closed circulation. The drying gas taken off from the lower part of the body is heated by element of a heating device and the heated drying gas is fed to the upper part of the body.

Abstract: A system for heating a pool of water is provided. An inlet is provided for liquid to be delivered to the pool of water. The system includes an attachment apparatus having a body defining a fluid passageway from a first opening to a second opening. A third opening is disposed between the first and second opening. The attachment connects to the inlet for receiving the liquid. An adjustable diverging mechanism is mounted to the attachment operable to redirect flow out of the third opening. A tube having a flow channel and thermally conductive outer surface is coupled to the third opening and extends out of the pool to be exposed to environmental conditions and absorb thermal energy. The liquid passing through the flow channel of the tube returns to the pool of liquid and heated when passing through the tube prior to returning to the pool.

Abstract: During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved.
