    在采暖锅炉的选型中,应根据采暖锅炉的功率和居室内采暖系统的实际情况进行选择。既要使采暖炉能满足居室的取暖要求,使房间能快速达到所设定的温度,又要保证采暖炉卫生热水供给量能满足人们的日常生活、洗浴的要求。因此,在选型中我们应当注意以下几方面:
    In the selection of heating boiler, the heating system should be based on the power of the heating system and the actual situation of the heating system to choose. Not only to make the heating furnace can meet the requirements of heating room, the room can quickly reach the set temperature, but also to ensure the sanitary hot water supply heating furnace can meet the people's daily life, bathing requirements. Therefore, we should pay attention to the following aspects in the selection:
    1.采暖锅炉的功率:
    1 the power of the heating boiler:
    采暖锅炉的功率主要为了满足卫生热水需求。在采暖方面,我们只需保证采暖炉的最大输出功率不小于房间的总采暖负荷需求即可。
    The power of heating boiler is mainly to meet the demand of health hot water. In terms of heating, we only need to ensure that the maximum output power of the heating furnace is not less than the total heating load demand of the room can be.
    2.流量、汞压:
    2 flow, mercury pressure:
    采暖锅炉为采暖系统中的一部分,进行系统设计和采暖锅炉的选型当中,在考虑采暖锅炉提供的采暖水流量能满足居室内的采暖需求同时,应使采暖系统?形成的阻力不超过机器内部本身循环泵在此流量下所提供的泵压。
    As part of a heating boiler heating system, the system design and selection of heating boiler, considering heating water flow heating boiler provided can meet indoor heating demand at the same time, should make the heating system? The formation of the resistance is not more than the machine itself circulating pump in this flow under the pressure provided by the pump.
    注:采暖炉之上采暖系统的物理高度与水泵的压力(扬程)没有关系。因为采暖系统?是密闭系统,系统高度所造成的压力同时作用在泵的两侧并使其相互平衡,这与水用泵送入冷却塔之类的敞口水箱并不是同一回事。
    Note: heating furnace above the physical height of the heating system and pump pressure (head) does not matter. Because the heating system? Is a closed system, the pressure caused by the system at the same time the role of both sides of the pump and make it balanced, and the water pump into the cooling tower and the like the open water tank is not the same thing.
    3.锅炉系统水容量:
    3 boiler system water capacity:
    系统内的水加热后膨胀,应考虑系统总水容量在采暖炉膨胀水箱所容许的范围内。
    The water heating in the system should be expanded, and the total water capacity of the system should be taken into account in the allowable range of the expansion water tank of the heating furnace.
    系统内的水被加热后将会膨胀,其膨胀的水?均容纳在膨胀水箱之内,如此时系统的水压力超过采暖炉的安全放散压力,采暖锅炉将实行自动放散。此种情况下,当系统水温降低后,水的容积变小压力降低有可能出现系统压力不够而影响采暖炉的正常运行。
    When the water in the system is heated, it will expand. Are accommodated in the expansion tank, so when the system pressure exceeds the water heating stove heating boiler pressure relief, will implement the automatic spread. In this case, when the system water temperature is reduced, the volume of water becomes smaller and the pressure of the system can not be enough to affect the normal operation of the heating furnace.
    4.卫生热水供给量方面:
    4 sanitary hot water supply:
    采暖锅炉具有两种功能:即能满足居室内采暖的需求,又能提供适温、适量的卫生热水,以满足用户洗浴和冬天用水的需求,在锅炉选型时,应充分考虑用户冬天热水的使用需求。
    The heating boiler has two functions: to meet the demand of indoor heating, and can provide the optimum temperature, the amount of hot water, bathing and winter water to meet user needs, in the boiler selection, should fully consider the user demand for the use of hot water in winter.
    冬季时,由于水的基础水温较低(约5℃左右),在标准温升(Δt=25℃)的情况下,不能满足用户的使用要求;采暖炉在高温升(Δt=35℃)的条件下,采暖炉卫生热水的产率将变小。此时,为获得适温、适量的卫生热水应充分考虑采暖炉的功率。
    In winter, the water temperature of the base lower (about 5 degrees Celsius), the standard temperature (t=25 DEG C) condition, cannot satisfy the requirements of users; heating furnace in high temperature (t=35 DEG C) under the condition of heating furnace with hot water yield will be smaller. At this time, in order to obtain the appropriate temperature, the proper amount of sanitary hot water should be fully considered the power of heating furnace.
