An arrangement for converting thermal energy from lost heat of an internal combustion engine into mechanical energy where a working circuit is provided for a working medium which can be heated and evaporated using the lost heat. An expansion machine for obtaining mechanical energy from the heat of the working medium is provided in the working circuit where the working circuit extends through a heat exchanger mounted upstream of the expansion engine in the flow direction of the working medium. The internal combustion engine includes a cylinder having a cylinder liner. A cooling duct is provided in the cylinder liner through which the working medium flows. The cylinder liner is formed by centrifugal casting where the cooling duct is introduced into one centrifugal mold as an insert prior to the centrifugal casting.

The invention relates to a method for detecting an unsealed location in a heat recovery system of an internal combustion engine of a motor vehicle. The heat recovery system has at least one working medium, in particular a combustible working medium, and a working medium circuit with at least one evaporator, a pump, and at least one expansion machine to allow an early and reliable detection of leakages in the evaporator.

A waste heat recovery system comprises an exhaust system, a thermal oil circuit, and a Rankine cycle circuit. The exhaust system is configured to provide exhaust gases. The thermal oil circuit comprises a first heat exchanger and a second heat exchanger. The first heat exchanger is positioned along the exhaust system. The first heat exchanger receives heat from exhaust gases and separately receives thermal oil such that heat from exhaust gases is transferred to thermal oil within the first heat exchanger. The second heat exchanger receives thermal oil from the first heat exchanger and provides thermal oil to the first heat exchanger. The Rankine cycle circuit circulates working fluid through the second heat exchanger separate from thermal oil such that heat from thermal oil is transferred to working fluid within the second heat exchanger. An expander utilizes heat within working fluid to produce mechanical energy.

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.

Apparatus and methods for recovering energy in a petroleum, petrochemical, or chemical plant as described. The apparatus includes a fluid process stream flowing through a petroleum, petrochemical, or chemical process zone. There are at least one variable-resistance power-recovery turbine, a portion of the first process stream flowing through the first power-recovery turbine to generate electric power as direct current therefrom. There is a single DC to AC inverter electrically connected to at least one power-recovery turbine, and the output of the DC to AC inverter electrically connected to a first substation.

A cooling module is coupled to an engine system and a Rankine cycle waste heat recovery system. The cooling module includes a heat exchanger for cooling a fluid of the engine system and a condenser for cooling a working fluid of the Rankine cycle waste heat recovery system, both of which extend in a width direction of the cooling module and are porous to a flow of cooling air in a depth direction of the cooling module. The condenser includes a first tubular header that extends in a height direction of the cooling module. A working fluid transfer tube fluidly couples the first tubular header to the Rankine waste heat recovery cycle system. The working fluid transfer tube has a first portion extending in the depth direction and a second portion extending in the height direction, the second portion being adjacent to the first tubular header in the width direction.
