This standard specifies technical requirements for arrangement, specification and material, supporting rib, explosion precautions, design of supporter and hanger for air & flue gas ducts/raw coal & pulverized coal piping of fossil fuel power plant boilers, as well as selection for chimney exit velocity, etc. This standard is applicable to air & flue gas ducts/raw coal & pulverized coal piping design for steel structure of coal burning boiler with capacity is 65-2000t/h grade. It only proposes relevant technological design requirements for air flue gas ducts of nonmetallic structure. Design for air flue gas ducts of fuel oil and natural gas burning boilers, and air & flue gas ducts/raw coal & pulverized coal piping of coal burning boiler with capacity is less than 65t/h and is larger than 2000t/h grade may comply with this standard. Engineering concerning foreign affairs must consider condition and using standard of supplier and purchaser's country, it may use this standard by reference.
