区域供热计划可以作为使用低碳热源的推动因素。工业场所排出的热量可能用于供应这种方案，但各种限制因素限制了这种情况可能发生的程度。本研究估计热量，可以提供给区域供热网络从工业场所在英国（GB），在一系列的限制标准的背景下。现有的GB热量需求的空间分类数据库与以前对工业场所拒绝的热量的大小，温度和位置的分析相结合。然后，采用一系列不同的标准计算工业场地可以提供的热量。考虑的标准包括热源和需求之间的最大允许距离、被认为可行的需求的最小热密度、可能发生的热损失以及热需求的季节性曲线。使用吸收式热泵，由高温热驱动，以供应低品位的热量的潜在收益被发现是有限的。比较了工业场地排热的高低估计值。家庭和非家庭的热量需求进行了研究。虽然国内需求的总量较大，但它们往往发生在较低的密度，因此这两种需求可能会在供热中占据很大的份额。热需求的季节性对补充热源的需求比对总热量的影响更大。对于距离和热量需求密度标准被认为是最合适的，只有一半的热量是由工业拒绝可以利用区域供热网络。(C)2015年能源研究所。由爱思唯尔有限公司出版。保留所有权利。
District heating schemes can act as enablers for the use of low carbon heat sources. Heat rejected by industrial sites could potentially be used in supplying such schemes but various constraints limit the extent to which this is likely to occur. This study estimates the quantity of heat that could be supplied to district heating networks from industrial sites in Great Britain (GB), in the context of a range of limiting criteria. An existing spatially disaggregated database of GB's heat demands was combined with previous analysis of the magnitude, temperature and location of the heat that is rejected by industrial sites. The heat that could be supplied from the industrial sites to the heat demands was then calculated with a range of different criteria applied. The criteria which were considered included the maximum allowable distance between the heat sources and demands, the minimum heat density of the demands which was considered feasible, the heat losses that may occur, and the seasonal profile of the heat demands. The potential gains from using absorption heat pumps, driven by high temperature heat to supply lower grade heat were found to be limited. High and low estimates of the heat rejected by the industrial sites were compared. Domestic and non-domestic heat demands were examined. Although the domestic demands have a greater total, they tend to occur at lower densities and so it is likely that both demands will take a significant share of the heat supplied. The seasonality of the heat demands has a greater impact on the need for supplementary heat sources than on the total heat delivered. For the distance and heat demand density criteria considered most appropriate, only half of the heat which is rejected by industry could be utilised by district heating networks.
