What is the current operating pressure of waste heat boilers (please provide the latest pressure range)?
Our old boiler operates at a pressure of 12 MPa, with safety valve setting pressures of 13.5 and 14.2 MPa.
Reply to 2# Front-line employees: When was your defective boiler designed? ?
Reply to 1# liangj2009: The pressure range for waste boilers is quite wide; it can go as low as –0.3 MPA, or it can reach the 12 MPA pressure mentioned earlier. But to determine the pressure in the waste heat exchanger, it is first necessary to know the temperature of the heat medium. For example, if it is 12 MPA, and the corresponding saturated temperature is around 320 degrees, then the exit temperature of the heat flow from the waste heat exchanger must be at least 350 degrees, so as to prevent the exchanger from having an excessively large size. In short, you first need to tell the temperature of the hot medium entering and leaving the waste boiler, and then determine the pressure of the waste boiler.
Reply to 4# DXJ122: I mainly need to use one piece of data here; I’m not sure what the internal medium is I want to know the maximum operating pressure of waste heat boilers at present. Thanks for replying
The waste heat boiler for the conversion gas of the methanol plant, designed and supplied by Sichuan Aipu for CNOOC’s Inner Mongolia Tianye project, has a maximum pressure of 12.6 MPa and has been in normal operation for 6 years.
