Выбор и расчет теплообменного оборудования для паротурбинных циклов на низкокипящих рабочих телах

Abstract

A solution is proposed for estimating the mass-size characteristics of the heat exchange equipment included in the heat scheme on low-boiling working fluids. In order to reduce the cost of design in the implementation of the thermal schemes the possibility of using existing in the petrochemical industry type series of heat exchange equipment. A model is developed for calculating the heat-exchange equipment included in the steam-turbine cycle on low-boiling working fluids and to determine their main characteristics calculation studies were carried out. It is received, that use of such approach allows to choose the appropriate type of the heat exchanger and to estimate its weight and size characteristics. The main indicators of heat exchangers are determined, which serve to further assess the technical and economic feasibility of implementing heat schemes on different working fluids.
