How to choose a fluidized bed vertical tube furnace?

When choosing a fluidized bed vertical tube furnace, multiple factors need to be considered comprehensively to ensure that the selected equipment can meet the specific needs of experiments or production. Let’s take a look at what needs to be considered when choosing a fluidized bed vertical tube furnace!

Three commonly used fluidized bed vertical tube furnaces with three temperature zones (click on the image to view product details)

1. Heating performance
Maximum operating temperature: Select the appropriate furnace based on the maximum temperature required for experimentation or production. Ensure that the furnace can operate stably within the required temperature range and consider a certain temperature margin.
Heating rate: If the experiment requires rapid heating, a furnace with a faster heating rate should be selected.
Temperature control accuracy: Choose a furnace with high-precision temperature control capability to ensure the accuracy of experimental or production results. Fluidized bed vertical tube furnaces typically use sophisticated PID intelligent temperature control technology, with a temperature control accuracy of ± 1 ℃ or higher.

2. Furnace and furnace tubes
Furnace structure: The vertical furnace is easy to operate and maintain, especially for experiments such as powder experiments that require frequent sample collection and placement.
Furnace tube material: The furnace tube material should have good high temperature resistance and corrosion resistance. High purity materials such as alumina and quartz are common choices, depending on experimental conditions and sample properties.
Furnace tube size: Select the appropriate furnace tube size based on the required sample quantity, sample size, and heating efficiency for the experiment or production. The diameter and length of the furnace tube should be sufficient to accommodate the sample and ensure even heat transfer.

3. Fluidized bed design
Fluidization mechanism: Ensure that the fluidized bed design can effectively suspend the sample powder in the heating zone to improve heating efficiency and uniformity. Partial fluidized bed vertical tube furnaces use designs such as microporous ceramic plates to achieve this goal.
Gas circulation: Consider the flow path and velocity of gas entering from the lower end of the furnace tube to ensure that the sample can fully contact the gas and be uniformly heated.

4. Safety performance
Safety protection measures: The furnace should have comprehensive safety protection measures, such as over temperature protection, leakage protection, etc., to ensure safety during experiments or production processes.
Convenience of operation: Choose a furnace with a control interface and structure that is easy to operate and maintain to improve experimental efficiency and reduce operational risks.

5. After sales service and brand reputation
After sales service: Choose brands and products with good after-sales service so that problems can be solved in a timely manner during use.
Brand reputation: Choose products from reputable brands that typically have richer production experience and more reliable product quality.

6. Budget and cost-effectiveness
Budget: Choose the appropriate stove based on the budget range to avoid unnecessary waste caused by exceeding the budget.
Cost effectiveness: Taking into account factors such as furnace performance, price, and after-sales service, choose products with high cost-effectiveness.
