Regarding the construction of the gasification furnace?
Thread Content
I would like to ask everyone: Currently, the combustion chamber of the Texaco gasifier in my project is under construction. This combustion chamber has 4 thermocouple points, and it is necessary to use special-shaped bricks for construction, so that after construction is complete, the thermocouples can be inserted into the chamber to measure temperatures； There is another pressure measurement port that needs to be constructed tightly. I would like to ask everyone: if, after it is built tightly, the pressure sensing element cannot be inserted into the furnace interior (it only makes contact with the refractory bricks adjacent to the furnace wall), how can pressure be measured?
It shouldn’t be like that; it should have small holes or gaps. This pressure sensing element is different from ordinary ones – it also has an expanded cylinder (which is said to help stabilize pressure), and it’s designed to prevent dust accumulation as well.
According to experts: 1. Treat the refractory lining of the gasification furnace and the furnace body itself as rigid bodies, considering them as a whole; the pressure on any point inside the furnace or on its walls is the same； 2. When the gasification furnace is in operation, if there is a difference in pressure between the inside and outside of the furnace lining, the lining will shift. Therefore, it can be compared to an inflated balloon, where the pressure is the same at every point throughout the balloon (including the balloon wall) ； 3. The pressure gauge is a standard spring-loaded pressure gauge.
