METHOD OF USE OF HEAT FLOW

摘要

FIELD: recovery of waste heat obtained in the course of conversion of energy; heating of one flow due to cooling of other flow. SUBSTANCE: in energy conversion system process of cooling thermal engine is adequate to process of heating central thermal point utilizing waste heat obtained in the course of energy conversion process. Functional scheme of reconstruction of standard project use of thermal flow includes reduction of inter-thermal friction arising at mass transfer of flows at different temperatures which provides for effective use of central thermal point; rational use of recovered heat flow is determined by the following relationship: , where R is designed value of thermal power of consumer; magnitude of saving of fuel burnt in the course of energy conversion process corresponds to: , where Qf is heat of combustion of all kinds of fuel. EFFECT: enhanced efficiency. 2 dwgs
