3台14MW高温热水锅炉房工艺设计+CAD图纸(2)
Hot water boiler widely used in hotels, schools, hotels, residential and other enterprises and institutions of heating, bathing and living hot water, etc
The automobile factory of the secondary design boiler is located in Shenyang City, which is used for making automobile parts
High temperature hot water boiler room is newly built, the boiler room is mainly for the paint shop process, heating and the daily life of the heating required to provide the heat.
Public power station boiler room is located within the plant. The indoor air temperature is below 40 in summer, and the indoor air temperature is not less than 5 The boiler room is equipped with WNS type power 14MW boiler 3 with a hot water. The total rated power of the boiler room is 42MW, the rated outlet pressure is 1.25MPa, the water supply return water temperature is: 130 /70, and each weight 4kg.
Boiler fuel use natural gas. Water use tap water.
The main reference of the design of the boiler room principle and equipment, a book. The main design steps for the load calculation and then the equipment selection, the air pipe system and the calculation layout of the pipe system after the equipment selection.
Through 3 14MW high temperature hot water boiler room, the design of the boiler room is to understand the contents, procedures and basic principles of the boiler room, and to study the method and the process of design calculation, and improve the operation and drawing ability At the same time, through the design and consolidate the theoretical knowledge and textbook knowledge, and learn how to use these knowledge to solve practical problems.
