(One question per week) Gasification plant and framework

Reply to 2# lvjianghuagong: The key to whether a factory building needs to be enclosed or not depends on the location. If the temperature in your area is extremely low in winter, then it’s necessary to enclose the building; otherwise, it will be impossible to survive through the winter. However, while implementing sealing, it is necessary to consider possible gas leaks within the framework, pay attention to exhaust and heat exchange, and install CO alarm devices at key potential leakage points. As for whether to use a steel structure or a frame structure, it mainly depends on the timeline requirements of your project. In some sense, steel structures allow for faster progress, but even so, it is advisable to use a frame structure for the lower floors of a gasification facility. Whether to go with a high-end or low-end version should be decided based on your management’s choice regarding cost-effectiveness.

In general, factory buildings cannot be sealed off; it is essential to maintain ventilation in them. The frames can be made of Q234 or Q345 steel

Concrete framework + steel structure for some floors + covered with color steel sheets + floor exhaust fans + large-opening windows + high-power exhaust fans on the top floor + heating system with high heat dissipation capacity installed on the ground floor + pipeline heating outside the framework. Suitable for cold regions such as northern Shaanxi, Ningxia, Inner Mongolia, Xinjiang, Qinghai, Liaoning, Jilin, Heilongjiang, etc.

The design of the factory building is mainly determined by the local climate; in the south, an open design is obviously preferable. In the north, it must be kept closed; otherwise, winter will be very uncomfortable. Ventilation is mainly achieved through windows, which are left open in summer, while their usage in winter depends on the actual conditions. As for the frame structure, I think reinforced concrete is better, as gas is usually somewhat corrosive, and steel structures are prone to corrosion.

In fact, when considering all factors, steel structures are the better choice – they have a short construction period, are fast to build, and come at a lower cost. As for whether to use a closed or open design, you need to take the following factors into account: 1. Design standards, safety requirements, and environmental protection regulations. 2. Climate conditions: protection against high temperatures and freezing. 3. Cleanliness requirements for the factory building. Is there sandstorm? What is the grade of the factory building? 4. Energy-saving considerations, such as natural lighting and heating. 5. Building requirements. 6. Equipment requirements, construction, instrumentation. Electrical requirements.

The progress of steel structure construction is relatively fast; as for whether to seal it off or not, it mainly depends on the weather conditions. In that case, it’s necessary to ensure proper ventilation

According to the standards for high-altitude gasification plants, it is generally not allowed to have enclosed structures; ventilation is a major concern. However, it is impractical not to use enclosed structures in northern regions or areas with strong winds. The main goal is to protect against wind, so an approach of enclosing the lower and upper parts of the structure can be adopted – one layer at the bottom and one layer at the top. Axial flow fans and large windows should be installed in the upper part, but all these arrangements must undergo feasibility studies by professional fire safety agencies before they can be implemented

The workshops and frames in the north need to be enclosed; otherwise, it will be very difficult to endure in winter. The factory building framework must take into account ventilation, heating design, as well as the issue of explosion volume.

Everyone has discussed the issue of sealing the northern factory building; does anyone have any relevant specifications on this?
