很多工业部门(包括冶金工业),在生产的过程中都需要一定的热能。如何合理的选择热能的供应方式,使之节约能源,降低成本,已成为当前的一个重要课题,也是评价工艺生产过程完善程度的重要组成部分。本文着重讨论如何正确选择供热机组,提高供热系统的效益问题。一、工厂企业的供热 (即供汽)方式 1.单独工业锅炉供热; 2.热电联合生产装置供热(这里不包括余热利用的供热装置,因它纯属节能措施)。热电联合供热又可分为背压式和抽汽凝汽式汽轮机组两种。除此之外,近年来为适应同一供热系统中不同热用户对压力要求不同且差异较大的
Many industrial sectors (including the metallurgical industry) require some heat during their production. How to reasonably choose the way of supplying heat energy to make it save energy and reduce costs has become an important issue at present and also an important part of evaluating the perfection of process technology. This article focuses on how to correctly select the heating units to improve the efficiency of the heating system. First, the heating of the factory business (that is, for the steam) 1. A separate industrial boiler heating; 2. Combined heat and power plant heating (here does not include the use of waste heat heating devices, because it is purely energy-saving measures). Combined heat and power can be divided into two kinds of back pressure and steam condensing steam turbine. In addition, in recent years to meet the different requirements of the different heat users in the same heating system with different pressure
