Hot water reset. Hot water reset, also called outdoor reset ( ODR ), is an energy-saving automatic control algorithm for heating boilers that are typically fired with fuel oil or natural gas. A hot water reset control loop measures the outside air temperature; this information is used to estimate demand or heating load as the outdoor ...
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 ...
Because boiler feed water from cogeneration plants has much lower return rates than 100% condensing power plants, industries usually have to treat proportionately more boiler make up water. Boiler feed water must be completely oxygen free and de-mineralized, and the higher the pressure the more critical the level of purity of the feed water. [5]
A fire-tube boiler is a type of boiler invented in 1828 by Mark Seguin, [ 1] in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam .
Condensing boiler. Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the ...
Boiler (power generation) An industrial boiler, originally used for supplying steam to a stationary steam engine. A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low ...
An electric water boiler, also called a thermo pot, is a consumer electronics small appliance used for boiling water [ 1][ 2] and maintaining it at a constant temperature in an enclosed reservoir. It is typically used to provide an immediate source of hot water for making tea, [ 1] hot chocolate, coffee, [ 1] instant noodles, or baby formula ...
Thermal power station. A thermal power station, also known as a thermal power plant, is a type of power station in which the heat energy generated from various fuel sources (e.g., coal, natural gas, nuclear fuel, etc.) is converted to electrical energy. [ 1] The combustion or nuclear reaction of the fuel source in a boiler or reactor generates ...
