Configuring ASHRAE 90.1 Baseline Systems and Plants

Boiler efficiency (%) = 100 (heat exported by the fluid (water, steam ..) / heat provided by the fuel) (1) Heat Exported from the Boiler to the Fluid. If a fluid like water is used to transfer heat from the boiler - the heat transfer can be expressed as: q = (m / t) c p dT (2) where. q = heat transfer (kJ/s, kW) m / t = mass flow (kg/s) m = mass (kg) t = time (s) c p = specific heat (kJ/kg o C) dT = temperature difference …

Determining & Testing Boiler Efficiency for Commercial

3.2.6 Thermal efficiency of conventional power plants. The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.

Waste Heat Recovery Methods And Technologies - Chemical

Jan 01, 2013 · Economizers for boilers. An economizer recovers waste heat from fluegases by heating BFW, and hence reduces boiler fuel requirements. Flue-gases are often rejected to the stack at 30 to 70°C higher than the temperature of the generated steam. Generally, boiler efficiency can be increased by ~ 1% for every 22°C reduction in fluegas temperature.
