A cartridge heater is a tube-shaped, heavy-duty, industrial Joule heating element used in the process heating industry, usually custom manufactured to a specific watt ...
The ideal tubular grate heater would be built like an ideal heat exchanger with as large a surface area as possible with material suitable to minimize the heaters thermal deterioration yet provide good thermal conductivity with a high airflow rate, similar to your home furnace. However the unique environment of a fireplace and the burning of ...
Spray nozzles can for example be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles. Calculation
Methods include immersion in tanks of hot water or spraying with steam. The scalding may be hard or soft, in which the temperature or duration is varied. A hard scald of 58 °C (136.4 °F) for 2.5 minutes will remove the epidermis of poultry; this is commonly used for carcasses that will be frozen, so that their appearance is white and attractive.
A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.
30 kW resistance heating coils This radiant heater uses tungsten halogen lamps. Electric heating is a process in which electrical energy is converted directly to heat energy. Common applications include space heating, cooking, water heating and industrial processes. An electric heater is an electrical device that converts an electric current ...
In vehicles, heat coils are often called heater cores. On the liquid side of these heat exchangers, the common fluids are water, a water-glycol solution, steam, or a refrigerant . For heating coils , hot water and steam are the most common, and this heated fluid is supplied by boilers , for example.
An early automotive use was the "head bolt heater", invented by Andrew Freeman in the United States and patented on 8 November 1949. [ 1 ] [ 12 ] [ 13 ] These early heaters replaced one of the engine's head bolts with a hollow, threaded shank containing a resistive heating element.
