XX有限公司6t/h燃煤蒸汽锅炉房工艺设计 摘要t/h燃煤蒸汽锅炉房的工艺设计，该公司提供一块60000×20000mm的空地采用台SL6-1.25-WII型蒸汽锅炉，额定工作压力1.25MPa。本锅炉房原水硬度和含氧量不符合锅炉给水要求，需要进行软化和除氧处理。选用两台逆流再生钠离子交换器轮流运行使用。亚硫酸钠除氧GG6-15 No.6.9D的鼓风机与型号为GY6-15 No.10.5D的引风机。 在确定了该锅炉房各项设备的型号后，根据GB50041-2008《锅炉房设计规范》相关技术措施的具体要求，关键词： The design XX CO. LTD.6 t/h coal-fired steam boiler room process Abstract This design is for a hypothetical company 6 t/h coal-fired steam boiler room process design, the company provides a 60000 x 20000 mm of space as a foundation for boiler room. Given in the article through company data and the data required for the calculation of boiler room design, gives a rational of the boiler room equipment selection basis and main equipment models, such as: boiler model, selection of water treatment, air blower, the selection of the induced draft fan, etc. By computing the final decided to adopt 1 SZL6-1.25 - the WII type steam boiler, the rated working pressure of 1.25 MPa. Due to the boiler room raw water for the city tap water, the hardness and oxygen do not conform to the requirements of the boiler feed water, so the raw water to soften and oxygen treatment. Softening system chooses two counter-current regeneration sodium ion exchanger, take turns to run. the advantages of moving bed for water quality is high, can continuous working, convenient operation, less need to exchange dosage. Oxygen way for convenience, choose the sodium sulfite method in chemical oxygen. For fan and induced draft fan, smoke gas and air output, according to the calculated model is respectively chosen for GG6-15 No. 6.9 D blower and models for GY6 - No. 15 10.5 D of induced draft fan. When determining the type of the boiler room equipment, according to GB50041-2008 specification for design of boiler room and related to the specific requirements of the technical measures, determine the size of the different circumstances of boiler room configuration scheme, thus determines the boiler room placement of all equipments and soda pipes, the sm
