Abstract

Rational utilization of waste heat is one of the important measures to improve the energy utilization efficiency and save energy, and the crucial way of waste heat utilization is thermal vapor compression (TVC). The calculation method of efficiency evaluation of waste heat recovery by TVC is presented, which can be applied to predict the effect of energy saving when the parameters of waste heat deviate from the design condition. The comprehensive utilizations of waste heat in the viscous oil exploitation and exhaust steam in the drying process are taken as examples to compute the efficiency of waste heat recovery at different conditions, and the optimal regulation method at special condition is presented.
