The boiler adopts advanced mechatronics automatic control technology, high quality silicic acid encryption and insulation, reduce heat loss. Horizontal industrial boiler composes furnace body, access door hole, front and rear smoke chamber, insulation layer cover, burner interface, pipes, valves and instruments, platform and stairs, instruments and safety devices, supporting accessories, electrical control cabinet.
Figure 1 - schematic representation of natural/thermal circulation boiler and forced circulation boiler 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 boiler seems to be working fine but the radiators are cool. Can you give me some insight into my boiler circulation problem? Kate. Boiler Circulation Problems | Troubleshooting Hydronic Water Loops. Kate, there can be several things wrong that keeps the water from circulating through the water loop. The first place to start is the
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.

A LaMont boiler is a type of forced circulation water-tube boiler in which the boiler water is circulated through an external pump through long closely spaced tubes of small diameter. The mechanical pump is employed in order to have an adequate and positive circulation in steam and hot water boilers.
Circulation refers here to the flow of water, steam, or their mixture around the steam—water circuit in a boiler. In early days of boilers, steam was generated in a large vessel. The vessel was heated from outside, which would create a convective current within the large body of water.
Grainger carries multiple types of circulating pump, designed for use in closed loop heat recovery and hydronic systems. Or choose from Grainger's boiler pump selection to handle condensate and steam produced in boiler heating.
Therefore natural circulation is limited to boiler with drum operating pressure around 175 kg/cm2. #2.Controlled Circulation In Boiler: If the Operating pressure of boiler is between 180 kg/cm2 to 200 kg/cm2 then circulation in boiler is to be assisted with mechanical pumps, to overcome frictional losses.
In most boilers there is a natural circulation of water, the fundamental principle of which is based on the principle of thermosiphon. In a boiler with free natural circulation, the generating tubes are installed almost horizontally, with only a slight incline toward the vertical.
once-through and combined circulation type boilers. All boilers for power generation are nowadays water tube boilers. Natural circulation boilers General The natural circulation is one of the oldest principles for steam/water circulation in boilers. Its use has decreased during the last decades due to technology advances in other circulation types.
