摘要： A system for providing wind-assisted air supply to coal-fired power plants through the use of a wind funnel communicating with an air handler system of a coal-fired boiler is disclosed. The shape, size and orientation of the wind funnel may be controlled in order to optimize the collection of wind and generation of increased air pressure for delivery to the coal-fired boiler system. Increased operating efficiency of coal-fired power plants may be achieved with the wind funnel system.

摘要： A system for reheating a power generation system (10) including a boiler (12) having a waterwall (23) and a steam drum (25) with an input fluidly coupled to the waterwall (23) and an auxiliary heat source(70) to provide heated fluid. The system also includes a first flow control valve (94) connected to the auxiliary heat source and the boiler to control a flow of heated fluid from the auxiliary heat source (70) to the waterwall (23); a first isolation valve (390) disposed at a waterwall, to isolate circulation of heated fluid from the steam drum (25) to the waterwall; and a sensor to monitor at least one operating characteristic in the boiler. The system also includes a controller (100) to control at least one of the flow control valve (94), the isolation valve (390), and the auxiliary heat source (70) to control the amount of heated fluid supplied to the waterwall (23) when the boiler (12) is not generating steam.

摘要： Aspects of the present disclosure include a system for turbo-compression cooling. The system may be aboard a marine vessel. The system includes a power cycle and a cooling cycle. The power cycle includes a first working fluid, a waste heat boiler configured to evaporate the working fluid, a turbine, and a condenser. The condenser condenses the working fluid to a saturated or subcooled liquid. The cooling cycle includes a second working fluid, a first compressor configured to increase the pressure of the second working fluid, a condenser configured to condense the second working fluid to a saturated or subcooled liquid after exiting the first compressor, an expansion valve, and an evaporator. The turbine and first compressor are coupled one to the other. The waste heat boiler receives waste heat from engine jacket water and lubricating oil from a ship service generator. The evaporator cools water in a shipboard cooling loop.
