  • HEAT RECOVERY BOILERS - thermopedia.com

    HEAT RECOVERY BOILERS. Boilers of this type generate steam by extracting heat from hot fluid, generally a gas, which is produced as a by-product of a chemical reaction and has no intrinsic value as a chemical, or which is in the form of exhaust from a gas-turbine or internal combustion engine. Heat recovery boilers are also often found in Learn More

    with modern gas turbines, even this prob-lem has been solved. If the heat-recovery boiler operates with-out additional firing, the control range for the process steam will have an upper limit. This is because the maximum steam that can be produced by the heat-recovery boiler is dependent upon the gas turbine load. Comparison of the economicsLearn More
