本文根据能级及能级平衡导出余热有效利用的热力学新判别准则——能级差δΩ与折合绝对温度T_(eq)计算了当余热利用于背压式、动力式、供热式及抽汽动-热合产等四种方案时的δΩ及T_(eq)的值,并进行了分析比较,求出了除纯供热外的三种方案的最佳蒸发温度t_(t,opt),和决定动力式与背压式两种利用方案优劣的转变温度t_(inv).
In this paper, a new criterion of thermodynamics for the efficient utilization of waste heat is deduced according to the energy level and energy level balance - the energy level difference δΩ and the equivalent absolute temperature T_ (eq). When the residual heat is used in back pressure, power, heating and extraction - heat production and other four kinds of programs when the δΩ and T_ (eq) values, and were analyzed and compared to find the best addition to pure heat supply outside the optimal evaporation temperature t_ (t, opt), and to decide Dynamic and back pressure two kinds of programs to use the merits of the transition temperature t_ (inv).
