LIQUID LEVEL ESTIMATION IN A STEAM GENERATION SYSTEM

A method of estimating fluid in a steam generation system includes periodically determining steam flow rates and drainage flow rates to accurately estimate fluid levels. The method includes determining a first steam flow rate of a steam generator. Before a present steam cycle, determine a starting quantity of liquid in one or more liquid reservoirs. During a present steam cycle, determine a quantity of liquid remaining in the one or more liquid reservoirs by determining a time the steam generator injected steam and multiplying the time by the first steam flow rate. Based on the first steam flow rate, determine a time remaining before the quantity of liquid remaining in the one or more liquid reservoirs is below a threshold and the one or more liquid reservoirs needs to be refilled. With the drain flow rate, the steam generation system can be emptied with minimized dry cycle duration.

Method for reducing the oxygen content in steam generator wall tubes

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.

Operation of a vaporizer of a domestic appliance

In a method for operating a vaporizer of a domestic appliance, the vaporizer is filled at least to a predetermined filling level. The vaporizer can be emptied using an emptying arrangement. A time measurement is started, when a filling level falls below the predetermined filling level. A heating system of the vaporizer is switched on, when the filling level falls below the predetermined filling level. The time measurement is stopped, when the heating system has overheated, and a delivery output is calculated during emptying of the vaporizer, from a duration for emptying that is determined by the time measurement.
