The article presents methods of industrial tests of the of technical device utility model designed for boilers E-1,0-0,9G-3 QL-500, D-721 of small and medium capacity. The research is aimed at improving the efficiency of fuel combustion in the boiler furnaces due to uniform distribution of airflow when supplying it to the boiler burner
We have considered hybrid nontraditional and
renewable sources of energy in terms of optimizing
their work based on the knowledge of technical and
functional peculiarities of each. We used
classification of clusters of nontraditional and
renewable energy of sources, depending on the
proportion of replacing power in energy
consumption and on the type of nontraditional and
renewable energy of sources. We examined a
simulation model of the hybrid cluster using the
structural diagram and performed statement of the
problem by means of the full and multifactor
experiment. We applied the method of analysis of
non-stationary random process disturbing influences
We have presented a table of analogues of mechanical and
electrical quantities of a thermal power plant, which shows
the relation between the useful power of the engine and
mechanical efficiency, as well as the relationship between
engine parameters and regime of its operation; we have
also developed an electro-mechanical analogy, which
helped to get the expressions linking the useful engine
power with shaft speed, engine performance, coefficient of
mechanical resistance and mechanical efficiency with
speed, coefficient of drag and engine performance. Similar
expressions were obtained for the relations of these
variables with other sets of parameters. The article also
shows corresponding graphs. The expressions for the
maximum net power and corresponding speed of rotation
was found. Thus, the efficiency isÐ…. It is shown that in
larger (compared with the extreme) speed, the mode is less
efficient than with the smaller, for the same useful power.
A method is presented to measure the important
characteristics of the finished engine – motor operation and
its rotational drag coefficient used in the resulting
expressions
