direct heating การใช้

• As with direct heating, however, the ultraviolet mechanism is often found wanting.
• This process of direct heating due to magma transport is known as contact metamorphism.
• District heating by the steam is used in some countries and direct heating is applied to internal plant applications.
• In addition to the direct heating effect and the normal feedbacks, the methane breaks down to carbon dioxide and water.
• More record maximums are likely in the Middle West and Ohio Valley, but clouds will limit the direct heating from the sun.
• It is primarily used to hold small quantities of substances which are undergoing direct heating by a Bunsen burner or other heat source.
• In 2007, the world had a global capacity for of electricity generation and an additional of direct heating, including extraction by geothermal heat pumps.
• Short, potent and invisible, these rays account for most of the brightness change and have significant effects on Earth in addition to direct heating.
• The boiler for the S1 was the largest built by the Pennsylvania Railroad, with of direct heating surface and 500 1 inch tubes and flues.
• ReB 2 can be synthesized by at least three different methods at standard atmospheric pressure : solid-state metathesis, melting in an electric arc, and direct heating of the elements.
• More complex Curie-point irons circulate a high-frequency AC current through the tip, using magnetic physics to direct heating only where the surface of the tip drops below the Curie point.
• During this time Baer had also become interested in utilizing solar energy for direct heating of buildings, inspired by reading Farrington Daniels "'Direct Use of the Sun s Energy ".
• :: : I wouldn't expect much direct heating of the air by radiation, since a few feet ( or meters ) of air absorbs a very small percentage of infrared light.
• The sewerthermal system will take advantage of relatively constant high temperatures of effluent water and will use only 20 percent or less power than what is needed for a traditional, direct heating system.
• The asteroid or a chunk of it would be evaporated just as solid things next to a nuclear blast on the Earth are evaporated, due to direct heating by radiation, and this would form a fireball.
• They note that the Sun's overall radiance appears to ebb by only about one-tenth of 1 percent during the solar cycle _ which is too small to account for dramatic change on Earth, at least by direct heating.
• Much of the infrared and visible energy released is caused by the direct heating of the quartz material, 97 % of the near infrared is absorbed by the silica quartz glass tube causing the temperature of the tube wall to increase, this causes the silicon-oxygen bond to radiate far infrared rays.
• This causes the cathode to releases electrons into the vacuum, a process called thermionic emission . ( Some valves use " direct heating ", in which a tungsten filament acts as both heater and cathode . ) The alternating voltage to be rectified is applied between the cathode and the concentric plate electrode.
