Low Fuel Oil Temperature Effects On Boiler Operation

Fuel Oil | HFO | Marine Oil | Platts | Definitions

Fuel oil (also known as heavy oil, marine fuel or furnace oil) is a fraction obtained from petroleum distillation, either as a distillate or a residue. In general terms, fuel oil is any liquid fuel that is burned in a furnace or boiler for the generation of heat or used in an engine for the generation of power, except oils having a flash point of approximately 42 °C (108 °F) and oils burned

Boiler Cycling Considerations - Babcock amp; Wilcox

Many fossil fuel-fired boilers are now experiencing load cycling or on/off cycling operation. These modes of operation involve cycling a unit on and off line or reducing loads to absolute minimums in response to varying load demand. This can be caused by daily or weekly load shifts experienced on nights and weekends, power generators dispatching units to the grid which utilize a lower cost

Steam Boiler Questions and Answers

2019-10-1 · Is it possible to overheat heavy fuel oil thus causing any water in it to turn to steam and cause problems at the pump and burner? Answer: Yes it is. The temperature of the heavy fuel oil is very often 130°C to 150°C and water introduced to that temperature would immediately evaporate into steam; well it depends on the pressure too.
