Question:
The boiler in Example 8.1 uses 1,500,000 L of fuel oil per year. An instrumentation kit is purchased at a cost of $10,000 and is used to adjust the boiler operation so that the excess O2 is only 3 percent. Determine the payback of the instrumentation if the cost of fuel oil is $1.00/L.
Example 8.1
A flue gas analysis of an oil fuel-fired boiler indicates that the CO2 content is 11 percent, with a gas flue temperature of 343°C (650°F). Determine the overall thermal efficiency of the boiler. Use oil No. 2.
