摘要:
A cleaning system includes an explosive subsystem including: a plurality of detonation cords extending along a direction different from a vertical direction; and a locating assembly locating the plurality of detonation cords relative to each other. The locating assembly spaces each of the detonation cords apart from a system to be cleaned. The cleaning system includes a pressurized air blower assembly adjacent a portion of the system to be cleaned, the pressurized air blower assembly being configured to direct pressurized air towards the portion of the system to be cleaned after the detonation cords have been exploded.

A heat recovery steam generator includes a gas inlet for receiving a flow of exhaust gas from a gas turbine, a gas outlet opposite the gas inlet, at least one heat exchanger intermediate the gas inlet and the gas outlet, the heat exchanger having a plurality of heat transfer surfaces configured to transfer heat from the exhaust gas to a fluid within the heat exchanger, and a valve associated with the heat exchanger and configured to regulate a flow of the fluid through the heat exchanger. The valve is controllable from an open position to a closed position to decrease the flow of the fluid through the heat exchanger in order to effect an increase in a temperature of the heat transfer surfaces of the heat exchanger to clean the heat transfer surfaces.
摘要:
A volatile liquid vapor recovery system is used to recover vapors produced in the loading of shipping vehicles with volatile liquid product from a storage tank. The recovery system uses a primary vessel with an adsorption bed for adsorbing the volatile liquid vapors and venting clean air including oxygen to the atmosphere. The recovery system regenerates the adsorption bed by recovering the volatile liquid vapors from the adsorption bed and directly delivering said vapors to the storage tank. The system may be adapted to remove oxygen from the primary vessel prior to regeneration, such as by purging and venting the primary vessel with a purge gas or by providing a secondary vessel to receive oxygen and vapors from the primary vessel prior to regeneration of the first adsorption bed. Adsorbed volatile liquid vapor from the secondary vessel can be recycled to the primary vessel for conservation.
摘要:
A steam generator apparatus for generating steam from a feedwater inlet stream including impurities is disclosed. The apparatus includes a tubing circuit in communication with an inlet for receiving the feedwater stream, the tubing circuit having a substantially unrifled bore defined by a metal wall, and a heat source operable to deliver a heat flux to the feedwater stream through the metal wall of the tubing circuit, the heat flux being operable to cause evaporation of feedwater within the tubing circuit and to produce an outlet stream at an outlet of the tubing circuit, the outlet stream includes a steam portion and liquid phase portion, the steam portion being greater than about 80% of the outlet stream by mass, the steam portion providing sufficient cooling of the metal wall to maintain a wall temperature at less than a threshold temperature associated with safe operation of the steam generator apparatus.

摘要:
A method for operating a steam power plant having a water-steam circuit, according to which method the process wastewater produced is collected from the water-steam circuit, in a separated manner according to the degree of contamination thereof, in a number of partial wastewater quantities is provided. At least a first partial wastewater quantity having a first degree of contamination and at least a second partial wastewater quantity having a second degree of contamination are formed in the process. The second degree of contamination is higher than the first degree of contamination. The first partial wastewater quantity and the second partial wastewater quantity are mixed together in such a manner that a combined process wastewater is produced, which is fed to a wastewater treatment plant.
