Natural Circulation - an overview | ScienceDirect Topics

Natural circulation is caused by the density difference between saturated water and heated water partially filled with steam bubbles. In a natural circulation unit the water tubes are connected to a loop, Fig. 4.3. Heat is applied to one leg, called the raiser tube, where the watersteam mixture flows upward.

Thermosiphon - Wikipedia

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.

KEY COMPONENTS OF BOILERS | Boilers Guide

The NUK-HP®is a high-pressure natural circulation boiler operat- ing by the gravity circulation principle. Therefore circulating pumps are not required to oper- ate the NUK-HP®. Boiler water is used as the heat carrier. The water is evaporated in this boiler within a hermetically closed cir- cuit.

Why is my natural gas furnace leaking water?

Fired heaters (Image 3), also known as furnaces, may be used as a distillation column reboiler. A pump is required to circulate the column bottoms through the heat transfer tubes in the furnace's convection and radiant sections. The heat source for the fired heater reboiler may be either fuel gas or fuel oil.

30/06/2020 · The working principle of Central gas heating is not as complicated as other types of heating systems. When the natural gas burns, heat is generated in the furnaces burner. The heat produced in the furnace then passes through a heat exchanger, which makes it hot.
