Abstract: 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.

Abstract: A separator circuit for a steam generation system. The separator circuit comprises a steamer connection tube and a liquid bin tube that extends vertically between a steam outlet for providing steam to a cavity of a cooking appliance and a recirculation tube for routing condensation back into the provided steam generation system. A slide tube is sloped downwardly from the steamer connection tube to the liquid bin tube for gravitationally accelerating condensation from the steamer connection tube through the liquid bin tube and into the recirculation tube. A vortex section is located between the slide tube and the liquid bin tube and includes a choke wall. The choke wall extends from a first end decreasing a cross-sectional flow path of the vortex section to a second end in a direction of the liquid bin tube.
