Systemically structured adaptation of heat transfer in steam generators

The paper presents a model of the processes of heat exchange and combustion in steam generators. The model was created by the methods of system analysis and adapted to a five-step process scheme. For each of the stages (local systems) certain conditions for the separation of all factors and parameters into input, output and control factors are formulated, and the connections and boundaries between local systems are defined. As a model scheme of arrangement of structural elements of steam generators the most common U-shaped scheme is considered which is easily transformed into other schemes. The variety of systems for the preparation and supply of fuel combustion components is unified by output parameters which are input parameters for the intense combustion zone. The temperature distribution along the zone of fuel intensive combustion and the main volume of the furnace is realized basing upon the application of the theory of probability to the fuel-air mixture flow. The solved problem is a stage at a mode and constructive optimization of steam generators under stationary conditions, mainly, industrial TPP of average parameters, but can be extended to steam generators of other types and parameters.
