input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings. The efficiency data used for comparison between boilers …
Boiler Systems Pump Selection Typical modern boilers will fire natural gas as the primary fuel, with a percentage of these using #2 fuel oil as a backup fuel. A system designer should be aware of a couple of key points when in-volved with boiler fuel oil systems. 1) Most boilers firing fuel oil will have their own fuel oil pump.
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
Mass And Energy Balances Over Oil Fired Boiler . 2016-12-5 · The main objective of this experiment is to perform mass and energy balances over the oil-fired boiler and vacuum condenser. In addition, the thermal efficiency of the boiler when operating at steady state was to be obtained. The weights of carbon, hydrogen, and sulphur into the system.
Most fuel oils have a hydrogen content that ranges between 10 and 14%, and a carbon content that ranges between 86 and 90%.18Heating values for fuel oils are expressed in units of either British thermal unit per pound (Btu/lb) or per gallon (Btu/gal) at 60°F.

Costs are for gas- and light-oil-fired boilers, complete with pumps, controls and gauges, 15 pounds pressure for steam, 30 pounds for water. Costs do not include flue piping, electric wiring, pad, gas or oil piping. Add 12% for 125# water pressure, 25% for 150# steam. For heavy-oil- and combination oil- and gas-fired units, add 15%.
Typically, fuel consumption accounts for 80 percent of the operating costs for a gas- or oil-fired steam plant. Labor, depreciation, maintenance, and water treatment account for the other 20 percent. Fuel optimization and stack-emissions reduction are crucial.
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 …
Fuel nitrogen conversion is the more important NOx-forming mechanism in residual oil boilers. It can account for 50 percent of the total NOx emissions from residual oil firing. The percent conversion of fuel nitrogen to NOx varies greatly, however; typically from 20 to 90 percent of nitrogen in oil is converted to NOx. Except in certain large
