2018-8-5 · For example, a typical No. 2 fuel oil has a viscosity 40 SSU. A 500 hp boiler requires up to 115 gallons per hour of No. 2 oil. Using Table 2, and specifying a 1-inch nominal pipe size, gives 0.1 psi pressure drop at 100 gph, and 0.2 at 150 gph. Linear interpolation gives 0.13 psi pressure drop per 100 equivalent feet of pipe.

Efficiency of Gas Vs. Oil Furnaces Our Everyday Life

For example, a furnace with an AFUE rating of 90 percent means that 90 percent of the fuel is converted to heat and the other 10 percent is lost through the chimney. Regardless of whether powered by gas or oil, the accepted minimum ratings are 78 percent for a furnace and 80 percent for a boiler. Oil furnaces and boilers also require onsite

Boiler Combustion CleanBoiler.org

When firing fuel oils, NOx formed by fuel-bound nitrogen can account for 20-50% of the total NOx level. One method to reduce NOx levels from boilers firing distillate oils is through the use of low nitrogen fuel oil. Low nitrogen oils can contain up to 15-20 times less fuel-bound nitrogen than standard No. 2 oil (less than 0.001% fuel-bound
