摘要： A method and system for heat recovery and/or power plant cooling, incorporating an ejector configured to transfer vapor from a generator to a condenser. The ejector includes a converging-diverging nozzle to create a low pressure zone that entrains a fluid. The ejector is within a cooling fluid cycle line in heat exchange combination with an exhaust flue gas. Two fluid flows of the fluid cycle line are mixed via the ejector into a combined fluid, wherein the ejector adjusts a temperature and/or pressure of the combined fluid. Condensing the combined fluid provides a cooling medium.

摘要： A heat cycle system includes a cooling circuit and a Rankine cycle circuit in which an organic medium circulates. The Rankine cycle circuit includes an evaporator, an expander, and a condenser. Before warm-up of an engine, a control device executes a warm-up mode in which the organic medium is circulated through the condenser, the expander and the evaporator in sequence; after the warm-up of the engine, the control device executes a waste heat recovery mode in which the organic medium is circulated through the evaporator, the expander and the condenser in sequence. In the warm-up mode, by supplying energy to the expander, the control device compresses the organic medium passing through the condenser and supplies the compressed organic medium to the evaporator; in the waste heat recovery mode, by depressurizing the organic medium passing through the evaporator by the expander, the control device recovers the energy generated by the expander.

摘要： A method and system enabling the efficient use of thermal energy to provide kinetic energy and/or electrical energy. The method uses at least two heat exchangers for heating the working medium, a heat engine and a condenser. The working medium consists of at least two substances. The working medium is partially condensed on the primary side of the first heat exchanger, wherein heat is transferred to the working medium flowing on the secondary side and, subsequently, further condensation heat is transferred to a cooling circuit in a condensation heat exchanger on the primary side of the condensation heat exchanger. Subsequently, the working medium is redirected to the secondary side of the first heat exchanger. A separation of gaseous fractions of the working medium takes place in the condensation heat exchanger on the primary side.

摘要： A system and a method for controlling operation of a power plant system. The system has at least a gasifier, a boiler, an induced draft fan, and a baghouse. A controller in communication with the system is configured to implement a first stage and/or a second stage sequences after detecting loss of flame in the boiler using a temperature measurement device. The method includes automatically bypassing the baghouse and controlled (e.g., decreasing) the speed of the induced draft fan in the system to relight the boiler. The input feed to the gasifier can be limited and devices operated for a predetermined amount of time before reigniting the boiler.
