    影响管网输送效率的因素有三个,即保温、泄漏和水力失调造成的热损失(而国外基本上是保温损失),其中因外管网水平失调和供暖系统垂直失调而造成的热损失十分可观。外管网的水平失调和室内供暖系统的垂直失调损失的热量所占比例很大,必须改进。如今“煤改气” ,燃气的成本高,减少管网失调热损失显得十分重要。为减少管网热损失,应采用水力平衡系统和室温调控系统。
    There are three factors that influence efficiency of pipeline transportation, namely, heat preservation, leak and hydraulic disorder caused by the heat loss is basically heat loss (and abroad), including the external network level disorder and vertical heating system disorders caused by the heat loss is very considerable. Disorder of the level of the pipe network and vertical imbalance of indoor heating system heat loss proportion is very big, must be improved. Now "coal to gas", the cost of gas is high, reduce the network disturbance heat loss is very important. To reduce the pipe heat loss, hydraulic balance system and room temperature regulation system should be adopted.
    烟气冷凝回收技术是一项利用烟气冷凝回收装置回收九卅娱乐排烟余热的节能技术,应用烟气冷凝回收装置可将温度较高的锅炉排烟与温度较低的供暖系统回水进行热交换。一方面,低温的供暖系统回水可以降低高温烟气可回收烟气中的显热;另一方面,低温供暖系统回水将高温烟气中的水蒸气冷凝成水,回收水蒸气的相变潜热。相关研究资料表明,烟气冷凝回收装置可提高九卅娱乐实际运行效率达3%~8%。
    Gas condensate recovery technology is a use of gas condensate recovery plant recycling waste heat of exhaust gas boiler energy saving technology and application of flue gas condensate recovery unit can be high temperature of boiler smoke and low temperature of the backwater heating system to heat. On the one hand, the low temperature of the backwater heating system can reduce the sensible heat in the high temperature flue gas recycling flue gas; On the other hand, the low temperature water heating system water vapor condensation in the high temperature flue gas into water, recycling water vapor phase change latent heat. Research data show that gas condensate recovery device can improve the efficiency of gas boiler operation was 3% ~ 8%.
    要尽量减少供暖期内各锅炉的启、停次数和待机时间。因每次锅炉启、停都要经过吹扫,消耗燃气;而待机时间内,锅炉就相当一个大散热器,也要损失热量。
    Try to decrease the number of opening and stop for each boiler heating period and standby time. For each boiler are through scavenging, opening and stop gas consumption; The standby time, boiler is quite a big radiator, also want to loss of heat.
