The article presents the scheme and principle of operation of a combined fluidized bed unit with re-utilization of heat from exhaust gases of a diesel generator and indicates the requirements for the functioning and operation of these types of installations. It presents theoretical and experimental graphs of the required volumes of air replacement with diesel exhaust gases in nominal and fractional modes, fuel economy, transients of changes in the fluidized bed temperature from time to time when various disturbing effects are applied.

The article discusses methods of factor analysis to identify heterogeneity in the conditions of spatial distribution and flow formation in aquatic ecosystems. Various factor analysis algorithms were studied to take into account the conjugate action of many factors. Examples of ranking the established dependencies by the value of their own significance criteria are shown. Deficiencies of factor analysis methods in certain software applications were identified because of a possible incorrect interpretation of the results due to the complexity of the technology. The possibility of using factor analysis tools to describe the spatial structures of hydrological data and identify risk zones associated with the instability of the hydrological regime was identified.
