A smudge pot (also known as a choofa or orchard heater) is an oil -burning device used to prevent frost on fruit trees. Usually a smudge pot has a large round base with a chimney coming out of the middle of the base. The smudge pot is placed between trees in an orchard. The burning oil creates heat, smoke, carbon dioxide, and water vapor.
Bain-marie. A bain-marie ( English: / ˌbænməˈriː / BAN-mə-REE, French: [bɛ̃ maʁi] ), also known as a water bath or double boiler, a type of heated bath, is a piece of equipment used in science, industry, and cooking to heat materials gently or to keep materials warm over a period of time. A bain-marie is also used to melt ingredients ...
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 ...
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 ...
A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through faults to hot rock deep in the Earth's crust . Hot spring water often contains large ...
Pots for bedding plants. Many bedding plants were grown in the same old glass greenhouses with a boiler, fin tubing and manual ventilation. But the new greenhouses on the same property or at a new site were simpler and cheaper. The new greenhouses were made with pipe bows and covered with air-inflated double polyethylene roofs. [18]
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 ...
The athlete, who has won 14 Olympic medals for swimming, the most of any female Olympian, said she has POTS (postural orthostatic tachycardia syndrome). In "Just Add Water: My Swimming Life ...
