城市集中供热方式的探讨

城市集中供热方式可分为热电厂集中供热系统、锅炉房集中供热系统、混合系统。热电厂的突出特点是热电合产，使能源的有效利用程度提高，从而能节约燃料。但受诸多因素制约。集中锅炉房节能效果较热电厂差，但热电厂种种制约条件致使其不可能全部替代集中锅炉房，二者长期共存将起到取长补短的作用。应广泛探索提高集中供热经济性途径，使城市集中供热在节能工作中发挥应有的作用。

The discussion of city's concentrative heating

In selecting heating way, city should combine local situation, and bas e on energy?saving, protecting the environment, economy and be reasonable. Acco r ding to heat source, city's concentrative heating includes concentrative heating system of thermoelectricity plant and boiler room, hybrid system. The outstandi ng characteristics of thermoelectricity plant is thermo and electricity producin g together, thus the effective use degree of energy is increased and the fuels a re saved. Confined by many factors, the energy?saving effect of boiler room is l ess than thermoelectricity plant, but many confined conditions make thermoelectr icity plant can't take place of thermoelectricity plant. The long?term coexist o f these two concentrative heating ways will learn from others's strong points to offset one's weakness. The way to improve the economy of concentrative heating should be searched extensively, thereby, city's concentrative heating will exert its function in enegy?saving.
