Temperature Control of Industrial Water Cooler using Hot-gas Bypass
Abstract—In this study, we experiment on precise control outlet temperature of water from the water cooler with hot-gas bypass method based on PI control logic for machine tool. Recently, technical trend for machine tools is focused on enhancement of speed and accuracy. High speedy processing causes thermal and structural deformation of objects from the machine tools. Water cooler has to be app...
متن کاملX-ray pulse apparatus based on explosive electron emission
One of the basic problems of the design of the portable x-ray devices for the works under the field conditions is to get smallest possible weight and the overall sizes. The classical apparatuses, which contain thermo-emission X-ray tube and source of constant high voltage as a rule have weight about 15-30 kg, which strongly impedes their use in the nonstationary conditions. In the proposed work...
متن کاملHot Corrosion in Gas Turbines
DURING COMBUSTION in the gas turbine, sulfur from the fuel reacts with sodium chloride from ingested air at elevated temperatures to form sodium sulfate. The sodium sulfate then deposits on the hot-section components, such as nozzle guide vanes and rotor blades, resulting in accelerated oxidation (or sulfidation) attack. This is commonly referred to as “hot corrosion.” Sulfur in the fuel is gen...
متن کاملWater Temperature From Hot Water Outlets in a Major Public Hospital: How Hot is Our Water?
OBJECTIVES To measure the water temperature issuing from a representative sample of patient-accessible outlets around the Royal Adelaide Hospital. To initiate an audit cycle in the event of unacceptably high water temperatures to ensure their reduction. METHODS Samples were taken of water issuing from hot taps, showers, and hand hygiene basins in patient areas throughout the hospital, encompa...
