Abstract: A system and a method for reducing a risk of bacterial contamination in a water heater are disclosed. A bypass conduit is connected to cold water supply and hot water outlet conduits of the water heater with T-shaped fittings, the bypass conduit generally extending in a same horizontal plane as the fittings and running alongside a top surface of the water heater. A thermostatic mixing valve is integrated to the bypass conduit close to the fitting with the hot water outlet so that its mixed water outlet is connected to the fitting with the hot water and its cold water inlet is connected to the fitting with the cold water, its hot water inlet being blocked. The thermostatic mixing valve is adjusted to regulate the hot water temperature at the outlet of the system and to produce a thermosiphon loop in the system depending on whether there is extraction or no extraction of hot water from the water heater.

Abstract: In the disclosed solution sand to be cleaned is thermally cleaned by rotating the sand being cleaned in a large oven (1) by rotating the oven (1). Before cleaning, the sand may be pre-processed by crushing any lumps and cleaning the sand fraction by magnetic separation. Preprocessed sand to be cleaned and heat energy are fed (5) into the rotating oven. The oven (1) is set slightly inclined so that a second end of the oven (1) is lower than a first end. The inclination and rotating speed of the oven (1) as well as the feed amount of sand are adjusted, whereby the advancing speed of the sand may be adjusted, as well as the ratio of the sand being cleaned to the volume of the oven (1) kept as desired. The temperature of the oven (1) is monitored at the coldest area of the oven, which is substantially at the second end of the oven. The temperature of the oven (1) is adjusted by adjusting the amount of heat energy fed in.

Abstract: In a nozzle for feeding a combustible medium such as coal particles along with air into a furnace, the exit end of each splitter plate in the nozzle is reinforced by a stiffener having an external cross-sectional shape in the form of a continuous curve proceeding outward and forward from a first surface of the plate to a first location, inward from the first location to a second location beyond the level of an opposite second surface of the plate, and inward and rearward from the second location to the second surface. The stiffener can be hollow, and can also be provided with openings for the flow of cooling air from the interior to the exterior of the stiffener. The continuous curvature of the exterior of the stiffener avoids recirculating flow at locations adjacent the stiffener and thereby minimizes flame attachment and deposition of ash or fuel sediment onto the reinforced splitter plates.
