A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. [ 1][ 2][ 3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system. [ 4] This reduces plant operating costs and also helps to avoid thermal ...
Thermosiphon. Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces ...
An atmospheric water generator ( AWG ), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [ 1] or pressurizing the air.
Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses. Domestically, water is traditionally heated in vessels known as water heaters ...
An absorption heat pump ( AHP) is a heat pump driven by thermal energy such as combustion of natural gas, steam solar-heated water, air or geothermal-heated water [1] [2] differently from compression heat pumps that are driven by mechanical energy. [citation needed] AHPs are more complex and require larger units compared to compression heat ...
Liquid-to-water heat pumps (also called water-to-water) are hydronic systems that carry heating or cooling through the building through pipes to conventional radiators, underfloor heating, baseboard radiators and hot water tanks. These heat pumps are also preferred for pool heating. Heat pumps typically only heat water to about 55 °C (131 °F ...
Both effects will reduce the pipe's overall thermal efficiency when used as a heat exchanger. Boiler feedwater is the water which is supplied to a boiler. The feed water is put into the steam drum from a feed pump. In the steam drum the feed water is then turned into steam from the heat. After the steam is used, it is then dumped to the main ...
A truckmount carpet cleaner is a carpet and upholstery cleaning unit that is generally mounted to the floor of a van or trailer. Its cleaning method is hot water extraction.The operator would park the van near the premises, connect the vacuum hose and solution line hose into the machine, bring the hoses into the building, and connect a carpet cleaning wand to the end of the hoses.
