The explanation of organic heat carrier boilers has just begun, so there is not much content and it is far from a comprehensive summary of the whole boiler, allowing everyone to fully understand and comprehend it. Therefore, in order to achieve this goal as soon as possible and satisfy everyone's curiosity and thirst for knowledge, the editor will continue to introduce this boiler, mainly elaborating on its structure and technical requirements, so that everyone can further learn and master more knowledge content.
The structure and technical requirements of organic heat carrier boilers mainly include:
(1) The strength of organic heat carrier boilers can also be calculated according to the prescribed standards, and their design pressure should be based on the working pressure plus 0.3 MPa, but the minimum cannot be lower than 0.59 MPa.
(2) The specific requirements for pressure components and non-destructive testing in boilers are:
a. Pipes, drums, headers, pipelines, etc. should be welded together.
b. The seam of the cylinder should be welded using submerged arc automatic welding; And the heating surface should be welded with gas shielded welding.
c. The welding process of organic heat carrier boilers should be carried out in accordance with the prescribed requirements.
d. Its flaw detection can use methods such as radiographic testing, ultrasonic testing, etc.
e. When the pressure bearing components are connected by flanges, their nominal pressure should not be less than 1.6 MPa.
(3) The flow rate of the organic heat carrier in the heating surface tube must be ensured, and phenomena such as overheating of the drum or premature aging of the organic heat carrier must be avoided.
