Cogeneration is the simultaneous generation and use of
both electricity (or mechanical power) and thermal energy
from a single fuel source. It is a technology that has been
used for years by industries, commercial institutions, and
municipalities that need both heat and electrical power. An
analytical approach has been developed...
A computer model was created using compressor and
condenser performance data to simulate vapor-compression
ammonia refrigeration system performance under various
operating conditions and strategies. The model was used to
estimate energy, demand, and cost savings resulting from
reduced condensing pressures.
Two ammonia refrigeration systems were selected for the
investigation into...
The literature cites several examples of investigations made
concerning the size of bubbles rising in small particle fluidized beds
at room temperature. In many practical applications, however, fluidized
beds require the use of large particles at very high temperatures.
Despite this fact, little information has been reported on bubble size...
This report presents the study of wood combustion and
combustion systems for a combined cycle wood-fired power
plant. The power plant consists of a twin air cycle and a
single steam cycle. The fuel for this power plant is wood
and wood waste with particle size in the range of...
The object of this research study is to investigate and provide
some fundamental information about bed slumping in a partially defluidized
bed combustor. Due to the difficulty in making measurements and
observations at high temperature, a dynamically similar cold phase
fluidized bed was used to model the high temperature case....
Adequate lubrication is of the utmost importance in internal combustion engines. Low temperature operation with low-proof alcohol may create some operational problems if alcohol and or water accumulates in the crankcase oil. Condensates of unburned alcohol and water may be blown into the crankcase oil with blow by gases. The...
Effective combustion of waste fuels requires an
understanding of the fuels characteristics. Gaseous and
particulate emissions, ash residues and combustion
properties are of interest to many; those that produce and
sell heating units, utilities interested in using the fuels
for power generation, regulatory agencies, municipalities
needing to solve a disposal...
