摘要： A steam generator includes a tank with a water inlet valve, a steam outlet, an electric immersion heater in said tank, and a normally closed drain valve. A water level control, connected to the inlet valve and the heater, is arranged to apply power to the heater only when it is immersed, and to admit make up water into the tank as steam is used. A drain valve control is connected to said drain valve and operates to open the drain valve to flush the tank only upon starting the generator after completion of a generator cooling period sufficient to condense residual steam in the tank which follows shut down of the generator. The completion of such a cooling period is sensed by either a pressure sensitive or a temperature sensitive switch which responds to conditions in the generator. The switch is connected to the drain valve control to prevent opening of that valve should the generator not be cooled to ambient temperature.

摘要： A device for scavenging condensate from long heat exchange tubes by recirculating the steam which is passed through one portion of a U-shaped tube bundle through another portion of the tube bundle and thus reducing the build-up of slugs of liquid in the tubes by increasing the velocity therethrough without reducing the heat transfer surface and also protecting the welds which seal the tubes to the tube sheet from thermal shocks and stresses by incorporating a thermal sleeve in the device which cooperates with the scavenging of condensate from the tube to provide optimum protection.

摘要： In a method for reducing the oxygen content in the flow volume of tubes of erected and installed tube wall regions or tube wall segments of a steam generator or steam boiler of a power station fired, in particular, with carbon-containing fuel, a solution is to be provided which eliminates or at least diminishes the problem of the incorporation of atmospheric oxygen into the boiler water which arises when tubes of the steam generator wall are being filled with boiler water and/or when boiler water is being discharged from these tubes. This is achieved in that an inert gas or an inert gas mixture is introduced into tubes of the tube wall regions or tube segments, through which boiler water or steam formed from this flows when the power station is in operation, before filling with boiler water or steam, in a way whereby gaseous oxygen present in the respective flow volume of the tubes, particularly in the form of atmospheric oxygen, is displaced, and/or an inert gas or an inert gas mixture is introduced during a discharge of boiler water or steam from the respective flow volume of the tubes, in a way whereby the free volume occurring is filled.

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 and a control method thereof are disclosed. The control method includes supplying water to a first chamber (C1), turning a heater (83) on, wherein power is supplied to the heater (83) to heat the heater (83) at a third temperature so as to generate steam, preventing overheating, wherein power supplied to the heater is cut at a first temperature so as to prevent overheating of the heater, and determining scale, wherein power supplied to the heater (83) is cut at a second temperature lower than the first temperature and then is resupplied after a predetermined time so as to prevent malfunction of the overheating prevention, wherein, when a time interval for the temperature of the heater to rise from the third temperature to the first temperature is within a predetermined time, determining scale is not performed.
