Methods and systems for generating power (and optionally heat) from a high value heat source using a plurality of circulating loops comprising a primary heat transfer loop, several power cycle loops and an intermediate heat transfer loop that transfers heat from the high-temperature heat transfer loop to the several power cycle loops. The intermediate heat transfer loop is arranged to eliminate to the extent practical the shell and tube heat exchangers especially those heat exchangers that have a very large pressure difference between the tube side and shell side, to eliminate shell and tube, plate type, double pipe and similar heat exchangers that transfer heat directly from the primary heat transfer loop to the several power cycle loops with very high differential pressures and to maximize the use of heat transfer coils similar in design as are used in a heat recovery steam generator commonly used to transfer heat from gas turbine flue gas to steam or other power cycle fluids as part of a combined cycle power plant.

System and method for the generation of heat and power using multiple loops comprising a primary heat transfer loop, a power cycle loop and an intermediate heat transfer loop

Systems and methods for transferring and converting heat to a power cycle using a plurality of heat transfer fluids, loops and heat exchange devices to convert heat to useful work and/or power. Power is generated using intermediate heat transfer loops (IHTL) and an intermediate heat transfer fluid (IHTF) to cool the hot exhaust power cycle fluid (PCF) stream that is at or above its critical conditions. The temperature of the IHTF can be increased by 100&#xb0; C., 150&#xb0; C., 200&#xb0; C., 250&#xb0; C., 300&#xb0; C., 350&#xb0; C., 400&#xb0; C., 450&#xb0; C., 500&#xb0; C., 550&#xb0; C. or more by exchanging heat with the PCF, either directly or indirectly.

Methods and systems for producing a thermally converted product stream (and optionally heat and power) from a high value heat source using a plurality of circulating loops comprising a primary heat transfer loop, several substantially not recirculated process heater, reactor or separator systems and an intermediate heat transfer loop that transfers heat from the high-temperature heat transfer loop to the several process heater, reactor or separator systems. The intermediate heat transfer loop is arranged to eliminate to the extent practical the shell and tube heat exchangers especially those heat exchangers that have a very large pressure difference between the tube side and shell side, to eliminate shell and tube, plate type, double pipe and similar heat exchangers that transfer heat directly from the primary heat transfer loop to the several process heater, reactor or separator systems with very high differential pressures and to maximize the use of heat transfer coils similar in design as are used in a heat recovery steam generator commonly used to transfer heat from gas turbine flue gas to steam or other power cycle fluids as part of a combined cycle power plant.
