摘要:锅炉在人民生活生产扮演着极其重要的角色,无论是居民的冬季供暖,家庭及旅馆、体育馆、健身中心等建筑物内的生活热水,还是工厂内生产提供动力及热量,都需要锅炉来提供热量。
本设计针对某小区进行了锅炉房设计。在本文中详细阐述了该锅炉房设计的原理和设计依据,计算了锅炉房热负荷、水循环系统及补水系统流量及管径。对锅炉进行了燃料燃烧计算和热平衡计算、烟风阻力计算。计算出了锅炉最大热负荷为10.6MW,锅炉水循环量为158.4t/h,锅炉热损失为17.109%,送风机流量为2.44m3/s,压力为208.03pa引风机流量为2.52 m3/s,压力是6112.46pa以及烟囱高度为45m。根据以上设计及计算结果,本设计给出了由三DZL4.2-0.7/95/70-A型锅炉组成的锅炉房系统,并对风机及泵进行了合理的选择。此外,本锅炉房原水硬度不符合锅炉给水要求,需要进行软化处理。根据补给水流量的计算,本设计选用三台型号为LNN-1200/20的无顶压固定床逆流再生离子交换器。35040

Design of a Residential Boiler Room.
Abstract:Boiler plays extremely important role in people's production and life, both residents of heating in winter, hot water of life in the family and hotel, gymnasium, fitness center in the building or factory production provides power and heat, boilers need to provide heat.
This design for a residential area of the boiler room design. In this paper, the principle and design basis of the boiler room design are described, and the heat load, the water circulating system and the flow rate and the diameter of the boiler are calculated. The calculation of the fuel combustion, the calculation of heat balance and the calculation of the air resistance of the boiler are carried out. Calculate the maximum heat load of boiler 10.6MW,boiler water circulation 158.4t/h, boiler heat loss 17.109%, send flow fan 2.44m3/s pressure 208.03pa cited flow fan is 2.52 m3 / s, the pressure is 6112.46pa and chimney height to 45m. According to the design and calculation results, the boiler room system composed of three DZL4.2-0.7/95/70-A boiler is given, and the reasonable choice of the blower and pump is given. In addition, the boiler room water hardness does not meet the boiler feed water requirements, need to soften the treatment. According to the calculation of the supply water flow, the design of the three models of the LNN-1200/20 no top pressure fixed bed current regeneration ion exchanger.
