Mathematical aspect of the performance of the action of the reduction-cooling plants.
Abstract
The concept of a reduction-cooling unit and a desuperheater is disclosed. The determination of the main components of the process of reducing the pressure and temperature of the steam used has been carried out. The diagram of the reduction-cooling unit with a detailed description of all components and the separation of the cooling water and live steam flows is given. Also marked are the input pressure and temperature values set at the start of the reduction and cooling unit. The cooling algorithm is described with an indication of all components. The level of reliability of the reduction-cooling unit is disclosed and the main negative impacts that occur during the operation of the reduction-cooling unit are emphasized. It is indicated that the efficiency of the reduction-cooling unit, the level of its productive action underlies exergy. The mathematical substantiation of the performance of the operation of the reduction-cooling units is given. An equation of exergy balance for a reduction-cooling unit and a diagram of exergy flows of a reduction-cooling unit are proposed. Separately, the equation of the heat balance of the reduction-cooling unit and the material balance. The formula for determining the flow rate of live steam and calculating the flow rate of cooling water is given. The parameters used in the analysis of the operation of the reduction-cooling unit are highlighted separately.
