摘要： A method to enhance the production of oil from underground oil deposits recovers the anode exhaust stream components and thermal energy from a fuel cell for injection in a well pipeline to heat, displace and flow oil into a production well pipeline at optimal reservoir pressure and operating conditions. The process recovers and injects the GHG emission stream from a fuel cell anode exhaust stream into an oil reservoir to increase oil production.

摘要： A water heater with two non-condensing flues and a condensing flue(s) having a system to prevent condensation in the non-condensing flue(s). The downwardly extending first flue is connected by a 180 degree connector to an upwardly extending second flue. Between the non-condensing and the condensing flues is positioned a temperature sensor. A controller receives input from the temperature sensor and is connected to the burner to control the minimum power setting and duration so as to prevent the combustion gases from falling below a temperature at which water will condense at the temperature sensor so no condensation occurs in the first two flues. Burner power settings are minimized near a water tank setpoint to improve efficiency by increasing condensation.

摘要： A fan includes: an impeller including a main plate having a first plane, a plurality of first blades each formed the first plane, and a shroud formed integrally with the plurality of first blades; a fan case; a drive source; and a rotation shaft. The first blades each include a linearly protruding region that is linearly increased in height from an outer circumferential side to an inner circumferential side, and a curvedly protruding region that is curvedly increased in height from the outer circumferential side to the inner circumferential side, the height extending in a direction in which each first blade protrudes. The linearly protruding region is welded to the main plate. Accordingly, a highly durable fan can be implemented that allows sufficient durability to be maintained even under a high temperature environment or an acid environment.
