Abstract: A device for separating interconnected transport boats that are movable in a first plane in an intended direction of motion includes a substantially oval, non-circular separation disk aligned parallel to the first plane and connected to a rotary drive and a lifting device via a drive shaft. The separation disk is movable by means of the lifting device in the direction of the transport boats to be separated in order to engage with a corresponding total recess in the transport boats to be separated. In addition, the separation disk is rotatably movable in, and/or parallel to, the first plane by means of the rotary drive in order to separate the transport boats to be separated from each other by rotating the separation disk.

Abstract: A hot water system, such as a Domestic Hot Water (DHW) system, combines the best characteristics of a tankless heater and a hot water storage tank to provide superior energy and water savings and safety. The storage tank does not need an internal heat source. Tank hot water may be recovered through the tankless heater. A first control (A) activates hot water recirculation from the storage tank to safely heat pipes to supply, for example, a sink, with no wasted water. The tankless heater supplies a greater demand, such as for a shower or tub. A second control (B) activates a cold-water diverter to the supply from the storage tank to the tankless heater. A water flow sensor keeps the tankless heater as the hot water source until the water flow stops. The so-called cold-water-sandwich is eliminated, and waste of water or heat is reduced.

Abstract: A method for predicting a blowdown rate of one or more boilers includes generating output data with a first model that specifies an empirical relationship between multiple input temperatures, multiple plant gas feed rates, and multiple outputs of the boilers. The method further includes collecting an ambient operating temperature and a current steam demand of the boilers and comparing the ambient operating temperature and the current steam demand to the output data to determine a current required blowdown rate. Once determined, the blowdown rate of the boilers is adjusted according to the current required blowdown rate.

Abstract: The present invention relates to a method for performing a drying function after a cooking function, in particular after a steam cooking function, wherein said method comprises the steps of: running the cooking function or steam cooking function (12) for a predetermined time or being manually finished by the user, detecting and/or calculating (16; 26) at least one parameter value (Y; H; te) after the cooking function or steam cooking function has been finished, comparing (18; 28) the detected and/or calculated parameter value (Y; H; te) with a corresponding threshold parameter value (Yth; Hth; teth), checking, if the drying function is required, and running the drying function (22) if required.

Abstract: Before supplying ammonia, which is a flammable gas, into a chamber, the chamber is evacuated to eliminate residual gas from the chamber, and then nitrogen is fed into a combustion-supporting gas line to cause oxygen, which is a combustion-supporting gas, remaining in the combustion-supporting gas line to flow out. After supplying ammonia into the chamber, the chamber is evacuated to eliminate the ammonia from the chamber, and then nitrogen is fed into a flammable gas line to cause the ammonia remaining in the flammable gas line to flow out. Oxygen or ammonia and nitrogen are alternately eliminated on the downstream side of an exhaust part, and it is therefore possible to prevent the flammable gas and the combustion-supporting gas from being mixed with each other.

Abstract: This disclosure relates generally to a method and system for real time monitoring and forecasting of fouling of an air preheater (APH) in a thermal power plant. The system is deploying a digital replica or digital twin that works in tandem with the real APH of the thermal power plant. The system receives real-time data from one or more sources and provides real-time soft sensing of intrinsic parameters as well as that of health, fouling related parameters of APH. The system is also configured to diagnose the current class of fouling regime and the reasons behind a specific class of fouling regime of the APH. The system is also configured to be used as advisory system that alerts and recommends corrective actions in terms of either APH parameters or parameters controlled through other equipment such as selective catalytic reduction or boiler or changes in operation or design.

Abstract: A hot water circulation system comprises a water heater having a cold-water inlet and a hot water outlet. A water pump circulates water through the water heater to produce hot water. The hot water is circulated to a thermal bypass valve, which is configured to close when hot water contacts a heat activated seal. A bypass circuit is coupled between the hot water outlet and the cold water inlet of the water heater. The bypass circuit prevents hot water from circulating from the hot water outlet to the cold-water inlet when the thermal bypass valve is open and promotes circulating hot water from the hot water outlet to the cold water inlet when the thermal bypass valve is closed. Upon a temperature sensor sensing hot water entering the cold-water inlet, the water heater turns of the water pump.
