Low Fuel Oil Temperature Effects On Boiler Operation

Oil firing - ScienceDirect

Both low-temperature and high-temperature corrosion may result from oil firing, particularly when heavier grades are used. The possibility of corrosion is best considered and dealt with when the plant is designed, and the temptation to cut capital cost and risk corrosion should be resisted. Corrosion is briefly dealt with elsewhere (Ch.20.1 and

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

Operation. An electronic sensor is inserted into the boiler flue, near the boiler, ahead of any dampers or other sources of air leakage into the boiler or flue. The sensor is connected to a control panel that measures oxygen and sends a signal to a control damper on the burner air supply. From the Hays Cleveland OXY-MIZER™ data sheet:
