Fluidized bed combustion - Wikipedia

Fluidized bed combustion. Limestone is used to precipitate out sulfate during combustion, which also allows more efficient heat transfer from the boiler to the apparatus used to capture the heat energy (usually water tubes). The heated precipitate coming in direct contact with the tubes (heating by conduction) increases the efficiency.

Water Handbook - Preboiler & Industrial Boiler Corrosion

Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

How do fluidized bed boilers work? - Quora

Aug 29, 2017· The first step is to grind the coal (or other solid fuel) into a very fine powder. We describe it as the consistency of talc powder. From there it is blown into the boiler. The main part of the fluidized boiler is that they have a secondary step after the boiler tubes where the fines are captured and recirculated back to the front of the boiler.

Boiler Inspection

There are two types of steam boilers. One is the fire tube, which is made from one combustion chamber and many tubes. The hot gases that are produced during the combustion process pass from inside the tubes and make a heat transfer with the water that is on the outside of the tubes. The other type is a water tube steam boiler.
