Abstract:
A premixed dual fuel burner includes a burner head, a burner interior elongated along a main axis and having an upstream side enclosed by a swirler and a downstream side enclosed by a premixing section, and an injection component. The burner head, the upstream side and the downstream side are serially arranged. The swirler includes an inlet section for introducing air and a main gas fuel into the burner interior. The injection component has a tapering structure positioned along the main axis. The tapering structure extends from the burner head into the burner interior. The injection component has a burner head side and an injection side and tapers from the burner head side to the injection side along the main axis. At the injection side a liquid fuel outlet is present for introducing a main liquid fuel into the burner interior. The injection side is disposed in the burner interior. At least one of the at least one liquid fuel outlet is at a side – i.e. a side face of the tapering - of the injection side of the injection component.
Abstract:
Methods and systems of burning a multi-phase hydrocarbon fluid include determining a water content of the multi-phase hydrocarbon fluid, communicating the multiphase hydrocarbon fluid to a fuel port of a burner in a primary fuel flow, initiating a flame at the burner to combust the multi-phase hydrocarbon fluid, communicating an auxiliary fuel source to the burner fuel port in an auxiliary fuel flow, and controlling the primary and auxiliary fuel flows based on the water content of the multi-phase hydrocarbon fluid.
Abstract:
There is provided a system for producing heat energy comprising: an electrolyzer for effecting electrolysis of water to produce an electrolysis product material including gaseous molecular hydrogen, and a furnace, fluidly coupled to the electrolyzer for receiving the gaseous molecular hydrogen of at least the electrolysis product material, and configured for combusting the received gaseous molecular hydrogen.
Abstract:
A dual fuel heating system (10) can be used in a gas appliance. The system can have an air shutter (60) to regulate an amount of air that can mix with the fuel for combustion. The air shutter can be configured to have different positions depending on the type of fuel to be used.
Abstract:
A method as well as a burner are provided for introducing solid, liquid or gaseous fuel into the burning zone of a kiln, such as a rotary kiln for manufacturing cement clinker or similar products, where fuel is conducted through substantially concentric ducts (1, 6) and where primary air is conducted through two likewise concentric and annular ducts (8, 9) arranged around the fuel ducts, where the air in one of these air ducts (9) is made up of axially flowing air, whereas the air in the second air duct (8) comprises air which is caused to rotate about the centre axis of the burner, and where the portions of primary air can be independently controlled. The peculiar feature of the burner is that the primary airstreams are mixed at a relatively low velocity in a collecting duct (15) into a primary airstream which is subsequently accelerated up to a desired, relatively high velocity prior to being injected into the kiln via an annular nozzle (14). There is thus obtained effective mixing of fuel and air in an operationally reliable manner with a minimum loss of pressure, and the flame shape can be adapted to the optimum desired.
Abstract:
A variable-direction burner tip is coupled to a first actuator that, when actuated, alters a firing direction of the respective burner tip. A respective flexible hose may couple a fuel input to each burner tip to accommodate rotation of the respective burner tip. In a burner incorporating one or more variable-direction burner tips, the burner includes a burner throat having one or more burner throats therein, the burner throats being sized and shaped to accommodate variation in firing direction by at least one burner tip positioned within each of the burner throats.
Abstract:
A pressure regulating module for regulating the pressure of a first fluid using a reference pressure of a second fluid. A pressure transfer assembly including a piston slidably disposed within a cylinder bore between a control fluid chamber and a reference fluid chamber is dimensioned to provide a predefined radial clearance between at least a portion of the outer side wall and the inner circumferential surface of the housing along a predefined axial length of the main body. The predefined radial clearance and predefined axial length are dimensioned to control the flow rate and amount of fluid along one or more fluid communication passages formed between at least a portion of the piston and the housing inner circumferential surface from one or more high pressure fluid zones to a lower pressure fluid zone which can include a leak and/or weep orifice directing fluid to a drain and/or vent circuit.
Abstract:
A method is for determining information about liquid droplet fallout during operation of a gas-liquid flare apparatus. The method includes disposing a plurality of tiles in a spaced apart fashion over a monitoring area. A gas hydrocarbon fuel is injected into the gas-liquid flare apparatus to create a combustible flow, and a test fluid is injected into the gas-liquid flare apparatus such that the test fluid is dispersed into the combustible flow. The combustible flow is combusted in in the gas-liquid flare apparatus, resulting in fallout of liquid droplets of the test fluid onto the plurality of tiles. Images of the liquid droplets on the plurality of tiles are analyzed so as to determine the information about liquid droplet fallout in the monitoring area, using a computer. The information about liquid droplet fallout may be used to estimate combustion inefficiency of the gas-liquid flare apparatus.
