vacuum-water-boiler-t6

vacuum water boiler t6

The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.

water-tube-steam-boiler

water tube steam boiler

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

The type that circulates water using only the density difference is called a natural circulation boiler while the type that includes a pump is called a forced circulation boiler

Difference between natural circulation and forced

A forced circulation boiler is a boiler where a pump is used to circulate water inside the boiler This differs from a natural circulation boiler which relies on current density to circulate water inside the boiler In some forced circulation boilers the water is circulated twenty times the rate of evaporation

Natural vs Forced Circulation - Boiler and Pressure Vessel

· The forced circ boiler uses smaller furnace waterwall tubes ( 2" OD) and also may tolerate a lower circulation ratio so the downcomers may be smaller Compared to a nat circ boiler that uses 3" OD tubes and must strickly limit frictional pressure drop in the downcoomer and risers to ensure adequate circulation occurs

Natural Circulation - an overview | ScienceDirect Topics

412 is based on density differences The same principle can be seen in eg room on a cold winters day Warm air rises on the wall where the room is heated; subsequently cooled more dense air falls downwards on the opposite wall

Steam Boilers: Classification and Selection | Mechanical

In natural circulation boiler the circulation of water takes place due to natural convection current and density variation of fluid by the application of heat ie thermo-siphon This is based on the principle that the density of water is more than steam and as such requires a boiler drum The method is effective only up to a pressure less than 20 bar After this pressure the difference in density of water and steam
