The report gives results of testing three fuels in a small (732 kW) firetube package boiler to determine emissions of carbon monoxide (CO), nitrogen oxide (NO), particulate matter (PM), and total hydrocarbons (THCs). The tests were part of EPA`s Environmental Technology Verification (ETV) program. The thermal efficiency of the boiler was also calculated for each fuel. Fuels tested were a standard No. 2 fuel oil, the same No. 2 fuel oil emulsified with 30 vol% water, and a fuel naphtha emulsified with 30 vol% water. Emissions and thermal efficiencies measured when using the emulsified fuels were compared with those of the non-emulsified fuel. NO emission concentrations decreased 15--34% for the emulsified No. 2 oil and 33-51% for the emulsified naphtha compared to the No. 2 oil. CO and THC emissions were < 8 ppm (at 3% O2) and PM emissions were < 5 mg/dscm for these fuels. Boiler efficiency was 2--3 percentage points lower for the emulsified fuels than for the non-emulsified fuel.
