ABSTRACT:
A waste heat recovery method can provide heat recovery from exhaust gases, full firing of exhaust gases, and auxiliary burning, either simultaneously or independently. Such method is carried out by installing a tube-nested (or heat-absorbing water tube furnace-inserted type) combustion chamber in a boiler of a cogeneration system or combined cycle system or the like which generates both heat and power. The boiler is provided with a combined full firing burner and auxiliary burner confronted by the exhaust gas entrance. This structure allows for elimination of a separate auxiliary chamber and thus has made it possible to provide a waste heat boiler of a simplified structure which is smaller in size and thus occupies less space, at a reduced price and with a greatly expanded heat-to-electricity ratio. Accordingly, the boiler of the invention has a greatly extended range of applications.
