Issues regarding the ceiling height of the control room
Thread Content
Recently, while reviewing the standards, I had some questions regarding the ceiling height in control rooms. I wonder if there are anyone who has experience in designing boiler rooms; the standards for boiler room design do not address the issue of the clear height within such rooms. In the design manual for small and medium-sized combined heat and power plants (from around 2006), it states that the clear height in the boiler control room should be 3.6 meters, while that in the turbine control room should be 3 meters； According to the design specifications for small thermal power plants (2011 version), the clear height of the control room is 3.2 meters. I wonder why such a higher requirement is specified for the boiler control room; if anyone knows the reason, please let me know. I think the height of the control room should be related to its area; a larger area might allow for a higher height. Both the boiler control room and the turbine control room contain control cabinets and operation consoles – so why is there such a big difference in height? I wonder if it’s because of the height of the boilers
The reason why the clear height in the boiler control room is usually higher than that in the turbine control room may be related to the structure of the boiler itself and its operational requirements. The operation of boilers involves monitoring and controlling high-temperature, high-pressure equipment, and may require more space to accommodate the relevant equipment and ensure safe operation. Furthermore, the temperature and environmental conditions in the boiler room are also quite severe; a higher ceiling height can help improve air circulation and heat dissipation. The turbine control room, on the other hand, is primarily involved in electrical control and low-pressure operations, so it requires relatively less space. Overall, the differences in design standards may reflect the specific requirements of different devices in terms of operation, safety, and environmental management. .
According to the specifications for small thermal power plants, when the boiler and turbine share a single control room, the required clear height of that room is at least 3.2 meters. There is no significant difference in the equipment used for controlling the boiler and turbine within the control room; both use computers. The boiler is equipped with several industrial televisions, but large-screen displays are also typically used, so the height requirement isn’t that strict in such cases
In the case where a boiler and a turbine share a control room, the requirement of a clear height of not less than 3.2 meters is likely intended to ensure sufficient working space as well as the space needed for the operation of the equipment. Although primary devices such as computers and large screens may be similar in physical size, a shared control room may require additional space to accommodate more monitoring and control devices, as well as to ensure the comfort and safety of operators. Furthermore, the interior of the control room may also need to take into account the space requirements for equipment maintenance, such as sufficient space for equipment inspection and wiring arrangements. Therefore, even though similar electronic equipment is used in the boiler and turbine control rooms, the requirements regarding the clear height of these control rooms in the specifications are intended to take into account operational efficiency, safety, and ease of maintenance. .
The space becomes smaller when they are used together; 3.2 meters is required. When they are separated, 3.5 meters is needed for the boiler control room
The required clear height for the combined control room is 32 meters, likely due to the needs of integrated functions and space optimization. When separating them, the boiler control room requires 35 meters, which is likely because it needs additional space to accommodate more specialized equipment or to cope with higher heat loads and environmental challenges. An independent boiler control room may also require additional safety distances and flexibility in equipment layout to meet the special requirements of boiler operation. Therefore, when control rooms are shared, although the overall space may decrease, functional requirements can still be met through design optimization and proper layout. On the other hand, a separate boiler control room may place more emphasis on the specificity and safety of operations, thus requiring a higher ceiling height. .
