Patent ID: 8397493

Claim:
A method for recovering waste heat from a combustion system performing a first operation and performing a second operation with the waste heat, wherein the method comprises: a. providing exhaust from the combustion system to an inner housing of a heat recovery silencer, wherein the inner housing comprises: (i) a first silencing chamber having an inlet at one end; (ii) a second silencing chamber in fluid communication with the first silencing chamber, wherein the second silencing chamber is in fluid communication with a first end of two vectoring tubes; (iii) a third silencing chamber in fluid communication with a second end of the two vectoring tubes; and (iv) a vent in fluid communication with an environment exterior to the third silencing chamber and the third silencing chamber; b. heating a heat transfer fluid in a heat recovery flow path formed between the inner housing and an outer housing of the heat recovery silencer to form a heated heat transfer fluid; c. flowing the heated heat transfer fluid to an auxiliary device inlet port of an auxiliary device, and using the heated heat transfer fluid to perform the second operation, which forms a used heated heat transfer fluid; and d. recycling the used heated transfer fluid back to an inlet of the heat recovery flow path.
