供热是一项改善环境污染、经济效益较大的社会公益性事业,随着电力工业向自动化方向发展,对供热生产的安全可靠性提出了越来越高的要求。南区热网分东线、南线、中线、北线四条主管道,供应南市区、卢湾区170多家企事业单位的生产、生活用汽,扩建规模供汽用户发展到300家以上。在此之前用户用汽量积算抄报、汇总统计、结算、热值换算、热损平衡均采用人工方法,落后且容易产生操作误差,致使热网每年约有30%的经济损失。为了加强对供热生产的科学管理,根据南区热网系统的要求,从实用角度综合性考虑,将供热 Heating is a public welfare improvement of environmental pollution and economic benefits. With the development of the electric power industry towards automation, the safety and reliability of heating supply are set higher and higher. Southern Heat Network points east, south, center, north of the four main pipeline, supply Nanshi District, Luwan District, more than 170 enterprises and institutions of production and living steam, expanding the scale of steam users to 300 or more. Prior to this, the user calculated the amount of steam used to report, summary statistics, settlement, calorific value conversion, heat loss balance using manual methods, backward and prone to operational errors, resulting in heat network each year about 30% of the economic losses. In order to strengthen the scientific management of heating production, according to the requirements of the Southern District heat network system, from a practical point of view of comprehensive consideration, the heating
