摘要

A radiant tube assembly (1) includes a radiant tube (2) having a burner leg (4) with a burner therein, an exhaust leg (6) and a connector leg (14). A recuperator (32) is located inside the exhaust leg in a stream of products of combustion flowing through the exhaust leg. The recuperator has an air inlet port (50) at the outer end (40) and a mixing baffle (80) at the inner end (42). The mixing baffle causes combustion air and products of combustion to be mixed at the inner end of the recuperator and the mixture is supplied to the burner for combustion.
