The concept of the flame continuum for zone of intense burning of boiler unit

The problem of the decomposition for zone of intense burning of boiler unit is formulated in this paper. The rational scheme for solving the problem within the concept of the continuum of flame is proposed in this article. That allowed us to consider basic laws of heat transfer and aerodynamics at the bottom of the firebox of the boiler unit. The main features of the three elements of the scheme (the furnace environment, flare continuum and the enclosure of intensive burning) are defined with taking into account the definition of the boundaries between them. Characteristics of the furnace medium and fencing determined using accepted methods for calculating. The properties of the flame continuum are adapted to a heterogeneous flame on burning solid and liquid fuel. Furthermore, the task of determining the enthalpy is solved in one-dimensional formulation. When burning gaseous fuel the processes of aerodynamics are an important factor. In this case, the homogenous flame continuum is considered in a two-parameter formulation. A common characteristic of the combustion of fuels in three states of aggregation is a temperature distribution along the length of the flame. That allows us to consider heat transfer processes in each zone.
