摘要： A fuel injector for injecting fuel in a burner of a gas turbine where the fuel injector has a body with an inner hole and a valve element which is slideably arranged inside the inner hole. The body has a fuel inlet which is formed into the body for injecting fuel into the inner hole, wherein the fuel inlet is coupleable to a fuel supply line. The body further has a first outlet channel connected to the inner hole, wherein the first outlet channel is further coupleable to a burner. The valve element has a first passage which is formed such that in a first position of the valve element inside the inner hole, the first passage connects the fuel inlet with the first outlet channel and in a second position of the valve element inside the inner hole.

摘要： This invention reduces the amount of carbon monoxide introduced by a combustion system to the atmosphere, by furnishing a systems approach to optimize the amount of oxygen to be chemically combined with fuel upon ignition of both allowing the correct amount of carbon to combine with the correct amount of oxygen thus fully release the thermal energy stored therein. By so furnishing the level of oxygen with carbon of the fuel, more carbon dioxide is produced thus proportionally reduces the amount of carbon monoxide released to the atmosphere. The invention provides a heating system that surpasses the net and gross efficiency performance of a natural gas burner.

摘要： A fuel valve includes a cylindrical flow adjusting member having a cylindrical surface formed with two circumferentially extending V-shaped grooves for liquid fuel and air, respectively. The fuel valve further includes liquid fuel and air supply pipes having O-rings at their respective discharge ports which are kept in abutment with the cylindrical surface such that when the flow rate adjusting member is rotated to a position where the V-shaped grooves extend across and protrude from the respective O-rings, the discharge ports of the supply pipes communicate with the respective V-shaped grooves, so that liquid fuel and air flow. The depths, widths and positions of the respective V-shaped grooves are determined corresponding to an igniting position (preheating step), normal burning positions (high heat to low heat), and a discharge position such that the flow rates of liquid fuel and air can be adjusted in synchronization with each other.

摘要： The present invention materially enhances the quality of the environment and mankind by contributing to the restoration or maintenance of the basic life-sustaining natural elements. The present invention reduces the amount of carbon monoxide introduced to the atmosphere of a combustion system. This is achieved by furnishing a systems approach to optimize the amount of oxygen to be chemically combined with fuel upon ignition of both allowing the correct amount of carbon to combine with the correct amount of oxygen thus fully release the thermal energy stored therein. By so furnishing the level of oxygen with carbon of the fuel, more carbon dioxide is produced thus proportionally reduces the amount of carbon monoxide released to the atmosphere. The present invention provides a heating system that surpasses the net and gross efficiency performance of a natural gas burner.

摘要： A fuel injector for a turbine engine, the injector including a body including a mechanism for admitting fuel under pressure, a stop valve for feeding a primary fuel circuit, and a metering valve mounted downstream from the stop valve for feeding a secondary fuel circuit. The injector further includes at least one leakage channel, that can be formed by a thread, that extends from a zone situated downstream from the stop valve and upstream from the metering valve to a zone situated downstream from the metering valve to generate a permanent leakage flow in the secondary circuit.

摘要： A fire display assembly has a burner tray optionally located within a hollow space in the interior of a non-flammable structure. A porous element on or in the non-flammable structure has extensions from a lower surface thereof extending into fuel in the burner tray. The assembly can include a fuel tray connected to the burner tray by conduits which provide flow channels for liquid fuel between the trays. When a container of liquid fuel is placed in the fuel tray the fuel is dispensed and flows into the burner tray. Fuel in the tray is transmitted to the outer surface of the porous element. Flammable vapors from the liquid fuel at the outer surface are then ignited. The arrangement provides a continuous feed of fuel to the surface of the non-flammable structure and allows safe replenishment of the fuel in the burner while the flame is present.
