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.

The invention provides an apparatus for generating heat and transferring the heat to a heater head of an external combustion engine, preferably, a Stirling engine. Fuel and air are introduced into a combustion chamber and mixed to form an air/fuel mixture. The air/fuel mixture is combusted over a combustion catalyst positioned in physical contact with a heat spreader, which itself is positioned in physical contact with a heat acceptor surface. The heat acceptor surface is secured in thermal communication with the heater head. Depending upon the design of the heater head, heat flux from the heat acceptor surface into the heater head may occur radially or non-radially.

Excellent fuel atomization in a turbine engine may be obtained with fuel injectors 46 including elongated, laminar discharge orifices 72 and impingement surfaces 76 disposed in the path of fuel 78 being discharged through the discharge orifices 72. Preferably, the fuel 78 is discharged as a flat spray generally tangentially to the annular combustion space 40 of an annular combustor 26.

The present invention relates to a burner system, in particular for a gas turbine, with a main supply channel (2), debouching into a combustion chamber (1), for a fuel/air mixture having a swirler (5) and a burner lance (3) which passes through the swirler (5). To improve the transverse ignition properties between several such burner systems, optionally disposed on the burner chamber (1), and also to increase the flame stability, the burner lance (3) has, on the combustion chamber side with respect to the swirler (5) exit openings (12, 16) for fuel supplied to its interior or for a fuel-rich fuel/air mixture supplied to, or formed in, its interior.

A method and apparatus for conducting such method are disclosed for igniting a fragmented permeable mass of formation particles in an in situ oil shale retort. The method is conducted by forming a hole through unfragmented formation to the fragmented mass. An oxygen-containing gas is introduced into the hole. A fuel is introduced into a portion of the hole spaced apart from the fragmented mass. The fuel and oxygen-containing gas mix forming a combustible mixture which is ignited for establishing a combustion zone in a portion of the hole spaced apart from the fragmented mass. The hot gas generated in the combustion zone is conducted from the hole into the fragmented mass for heating a portion of the fragmented mass above an ignition temperature of oil shale.
摘要:
A burner includes a plurality of air nozzles open toward a furnace and which are disposed unsymmetrically with respect to the central axis of the burner and so combined that the velocity of combustion air to issue from one or more of the nozzles is higher than the mean air velocity through the total air nozzle opening area and the velocity of combustion air from the rest of the nozzles is lower than the mean velocity. The opening area of the lower-velocity air nozzle or nozzles accounts for from 30 to 60% of the total opening area. A fuel nozzle or nozzles are located within or adjacent the lower-velocity air nozzle or nozzles. The amount of air to issue from the lower-velocity air nozzle or nozzles is not more than 70% of the theoretical air for the fuel to jet out of the burner.
摘要:
A crude oil burner is provided particularly suited for oil well testing in Arctic and sub-Arctic regions having a plurality of aligned and spaced air cones to the rear end of which crude oil is delivered, and into which air is induced. Air is also available at the space between the cones and at the front of the front cone. Gas assist heads are provided connected to a ring at the space between the cones and connected to a ring at the front of the front cone for inducing air and aiding in the combustion of the crude oil to provide smokeless combustion. The burner can be mounted for turning in accordance with the wind direction to avoid undesired deflection of the flame by the wind.
