Studies on Combustion Characteristics and Flame Length of ...

Apr 06 2007 · Combustion characteristics flame structure and length in an oxy-fuel combustor have been experimentally investigated for a wide range of fuel nozzle diameters and fuel and oxidizer velocities. Measurements are made for the model combustor (Combustor I) as well as for the actual oxy-fuel combustor (Combustor II). The experimental results for Combustor I clearly reveal basic features

Heat Flux And Maximum Film Temperature For Fired Heaters ...

Dec 18 2012 · In general heat flux is the main determinant for the tube area of a fired heater. It has the units kW / m 2 in SI units and Btu / hr*ft 2 in English units. It is the rate of heat transmission through the tubes into the process fluid. The area used in the specification of heat flux is usually the outside tube area in the radiant section.

Calculation of Radiant Section Temperatures in Fired ...

Flame and effective gas temperatures are key variables that need to be accurately determined before analysis of heat transfer in the radiant section of fired heaters can be meaningfully undertaken. To facilitate the calculation of these temperatures appropriate equations were derived using two Computer Matlab programmes specially written for the purpose.

Boiler Questions and Answers regarding Your Boiler

You can take the reading over a few minutes and correct to one hour. So 1000 cubic feet/hour X 1050 btu/ cubic foot = 1050000 btu/hr at maximum input. Minimum Input meter clocked is 100 cubic feet/hour. 100 cubic feet/hour X 1050 btu/cubic boot = 105000 btu/hr at minimum input.
