I’m seeking help from experts regarding the design of HVAC boiler rooms. .
Thread Content
Dear experts, this is my first time dealing with the design of HVAC boiler rooms, and I have many questions. I would like to ask whether the requirements regarding the clear distance between boilers and walls as specified in the boiler room design codes must be met; does this distance requirement also apply to the space between boilers and columns? Additionally, what aspects need to be considered when designing the smoke and air ducts for boilers? Is it necessary to calculate the resistance balance, just as hydraulic balance is calculated for hydraulic pipelines? When there are many boilers, how should the smoke and air ducts be arranged? For more than ten boilers, how many of them should share one chimney? Also, which book is a good reference for learning about smoke and air ventilation systems? I’d appreciate everyone’s advice. Thank you in advance; I don’t have much money, but I’ll give it all to those who help me. Please assist me. . :(
A clear distance between the boiler and the wall is necessary. If it is a column, consideration should be given to the convenience of operation and maintenance. The calculation for smoke and air ducts can require the manufacturer to carry out it in conjunction with the boiler combustion calculation. http://bbs.hcbbs.com/thread-1593156-1-1.html
Practical Design Manual for Boiler Rooms
The last edit to this post was made by xyc114 on 2016-6-15 at 16:25. The function of the chimney height is to discharge the flue gases generated by boiler combustion through suction force. According to GB13271-2001, “only one chimney may be installed in each newly built boiler room.” The Design Code for Boiler Rooms (GB 50041－92) stipulates that the number of boilers in a boiler room should not be less than 2; however, if one boiler is sufficient to meet the thermal requirements and maintenance needs, then only one chimney is required； A new boiler room should not have more than 5 boilers, while during expansion or renovation it should not have more than 7 boilers. Moreover, boilers are located in areas with high population and industrial density; to facilitate the dispersion of emissions, regulations stipulate that \"each new boiler room may have only one chimney.\" The provisions regarding the number and capacity of boilers in the \"Code for Design of Boiler Rooms\" (GB 50041–2008) retain the aforementioned requirements while adding that \"in non-independent boiler rooms, the number should not exceed 4 units.\" Regarding chimneys, the following rules apply: “For fuel oil and gas boilers, it is advisable to provide a chimney for each individual boiler,” and “Fuel oil and gas boilers shall not share flues or chimneys with equipment that uses solid fuels.” Therefore, this revision makes the following adjustment to the provisions regarding boiler chimneys: it changes \"Each newly built boiler room may have only one chimney\" to \"Each newly built coal-fired boiler room may have only one chimney.\" ” The above content is taken from the letter containing comments on the \"Emission Standards for Air Pollutants from Boilers\"
