Burner made from moulded refractory bricks, esp. for waste incinerator

摘要

The burner, designed to be mounted in the wall of a combustion chamber, comprises a first outer assembly of moulded bricks (2), with a second assembly (3) situated inside it, and an expansion joint (A) between the two. The expansion joint is between 2 and 10 mm in width and filled with a mortar, an adhesive, or refractory concrete. The bricks in the outer assembly are shaped to form a ridge on which the inner assembly is mounted. The inner bricks are curved with wedge-shaped sides and include one (7) which acts as a key for the remainder. The burner is constructed by assembling the outer bricks first and then the inner ones, using a template and locking element.
