ABMA paper 9 00 - Johnston Boiler

The volumetric heat loading is an important criteria especially for fuels critical about stabilisation for combustion and low heating value gases. Low values of volumetric heat loading signifies an increased residence time in the furnace for the combustion to complete. The values used for the normal fuels range from 130 to 300 x 10 K.Cal/hr/cu.m.3

design is significantly different from that of any gas-fired burner, and it presents many more challenges during opera-tion than a gas-fired burner. For those reasons, most burners designed for liquid firing are also equipped with gas-firing capability. Therefore, oil burners for process heaters are typi-cally combination gas-oil burners.

H. Widell, in Biomass Combustion Science, Technology and Engineering, 2013 Furnace design. Just as coal-fired boilers are not designed in the same way as oil- or gas-fired boilers, neither can biomass-fired boilers be designed as coal-fired boilers, if they are to function efficiently. Biomass firing requires a larger furnace (i.e. a larger radiation heat transfer surface) than coal firing.

They power package boilers, start up larger furnaces with fluidized beds and grates, and heat many other processes. Larger burners have Combustion Control Systems (CCSs) which should be tuned periodically. To understand how to tune a gas and/or oil (usually #2 Diesel oil) burner, it helps to first understand how and why they work the way they do.
