Corrosionpedia - What is Natural Circulation? - Definition

Corrosionpedia explains Natural Circulation. In natural circulation boilers, the circulation of water depends on the difference between the density of an ascending mixture of hot water and steam, and a descending body of relatively cool and steam-free water. The difference in density occurs because the water expands as it is heated, and thus,

Boiler circulation systems: natural circulation and forced

Natural versus forced circulation typical schematic. In natural or thermal circulation type boilers, the rate of circulation depends strongly on the density difference between the unheated water and the heated steam-water mixture. The overall circulation rate (flow) in natural circulation systems mostly depends on the following factors: - Height of the boiler - Taller boilers yield a bigger pressure difference between the heated and unheated sections and consequently produce bigger flow rates.

Difference Between Low- and High-Pressure Boilers | Hunker

High-Pressure Boiler Definition. High-pressure boilers will heat steam above 15 psi and water at pressures that exceed 160 psig. Temperatures in high-pressure boilers will exceed 250 degrees F. Because of the elevated pressure at which these boilers operate, they need to be monitored to ensure safety at all times.

Colder feedwater replaces the water that rises, which creates the natural circulation. A typical boiler circulation (as shown below) will illustrate: Boiler feedwater being introduced into the steam drum. Cooler water sinking through tubes called "downcomers." Water absorbing heat from the tubes, then the heated water rising to the steam drum. Due to the critical need for water, modern boilers are equipped with automatic low-water trip switches.

BOILER BASICS AND TYPES OF BOILERS, DIFFERENCES

A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.
