shell furnace backpressure valve
Thread Content
Which expert knows where the back pressure valve used to maintain pressure in the shell furnace gasification system is installed, and what its operating temperature is? Thank you
The pressure of the Shell furnace itself is not directly controlled; rather, it is regulated by the wet cleaning process. I’m not sure if you are referring to the butterfly valve located downstream – it is usually installed in the wet cleaning section, on the 2nd floor of the framework, near axis 8, with an operating temperature of around 160 degrees.
Does the high-temperature and high-pressure fly ash filter have any effect on maintaining the pressure in the gasification furnace? :)
It is controlled by two valves of the 16PIC0008 type; the pressure inside the gasification furnace is regulated by determining whether these valves are opened for venting or not
It seems that butterfly valves cannot be used to control pressure, because they cannot withstand pressure – I’m not sure if that’s correct :)
Are the two valves of 16PIC0008 connected in series? Is it one as a backup and one in use?:)
The cold gas used in the system to mix with hot gas seems to have a temperature higher than 160 degrees; where does this cold gas come from? What valves are used to control the flow rate? Thank you :)
The flow rate is controlled by adjusting the speed of the rotary press plus the flow control valve FV0008
Thank you so much for the answers, masters :)
Is the compressor mainly used to compensate for the pressure loss that occurs as the coal gas flows through the pipes? Is that right? How large is this amount of loss approximately? Thank you very much
