A boiler's circulator pump is used to remove hot water from the boiler, and then pass it into heating devices such as the radiator or a convection pipe system. The power of the pump is enough to cause the water to travel right back up to the boiler from the pipework. Using a circulation pump is a great way of keeping water traveling throughout the system.

A novel suspension-floating-circulating fluidized combustion technology is proposed for burning coal slurry fuel in traditional circulating fluidized bed boilers (CFBB). This technology can solve some existing problems in large-capacity CFBB burning coal slurry. The principles of the suspension-floating-circulating fluidized combustion technology were introduced in detail in this paper.
A method, system and apparatus for a low bed pressure drop circulating fluidized bed (CFB) boiler associated with fast bed CFB combustion are disclosed. The CFB boiler may be operated according to the following set of conditions. In an upper area of a combustor of the boiler, a flow pattern of the two-phase gas-solid flow may be placed in a fast bed fluidization state.
QXX high-speed external CFB Boiler Advantages: 1, high combustion efficiency, energy saving evidently. Due to circulating fluidized bed boiler gas-solids mixed well, and the fuel particles could recycle burning, so the time of fuel kept in the furnace become longer, the combustion efficiency is up to 97-99%.
High combustion temperatures in coal-fired boilers can cause slag and fouling problems in the furnace, superheater and heater sections depending on the quality of the coal . Therefore, regular soot blowing is necessary to keep these areas clean. On the other hand, the combustion temperature in the CFBC boilers is low, around 900 ° C., which reduces the problems of slag or fouling.
The use of low-speed circulating fluidized bed design, combustion chamber has large cross-sectional area, and smoke speed is low, low flue gas concentration. B. The separator is designed in the exit of the combustion chamber, applies high-temperature separation method to prevent effectively the wearing of heating surface behind the separator.
Then Finds its way to power generation. PF firing technology shifted the Power generation from 15 MW to as high as 1300 MW in early 1970. When a solid fuel such as coal is reduced to the consistency of talcum powder and fired in an open furnace, the resulting combustion is almost equal to oil or gas firing—in Speed controllability, and Heat
