flue gas velocity in boiler – Coal Fired Steam Boiler Project

4) Make sure that the boiler received is configured for the correct gas (natural or LP).The BSI311, BSI346 and BSI380 may only be used with natural gas. 5) Boilers installed at altitudes above 2000 ft. require different burners and main burner orifice than those at sea level.

Nov 05, 2019 · Boiler flues are fitted when using combi, regular, and system boilers. The only exception that may apply to a small number of homeowners is a back boiler. This is a type of boiler that is fitted behind a fireplace. If you have a gas boiler behind your fire, the emissions will exit through your chimney, rather than via a boiler flue.

Location. Under the boiler flue position regulations, the flue has to be positioned a certain distance from any parts of the home that can be opened up such as windows and doors. How far this is will depend on the size of your boiler but is typically between 30-60cm above, below or to the side of an opening.

CFD simulation of fuel/flue gas section of the fire-tube

Flue Gas Analysis Calculations. Flue gases are formed on combustion of air with fuel in the presence of heat. Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel.

Experiment and Analysis on Flue Gas Low Temperature

This is because the flue gas velocity of x = 0.1 m, which is near the entrance to the convection chamber, is less than that of x = 1.0 m, leading to a smaller heat transfer coefficient and thus a lower flue gas temperature. The flue gas of upward flow carries out heat exchange with the tubes, and the flue gas temperature field also gradually becomes uniform.
