In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler. 3 Use of Economizer with Waste-heat Boiler. Where the exit gas temperature is above ca.225°C and the ratio of flue gases to weight of water evaporated is low (e.g. < 3:1), the use of an economizer may be justified economically. Under these circumstances the exit gas temperature may fall to < 140°C.
Jun 23, 2020 · Gas-fired boilers are fueled by either natural gas or propane, and are highly efficient.
CB-8488A. Steam. 10,000 to 500,000 lb/hr. Temperatures to 900°F. Steam pressures up to 2,300 psig. Gas flow rates up to 1,000,000 lb/hr. A, O, and D-type designs. The Cleaver-Brooks waste heat watertube boilers are offered in a single pass design or multiple pass design including furnace / radiant sections. Reusing waste heat for steam or power replaces the need for additional auxiliary-fired boilers.
The process gas waste heat boiler (WHB) is a critical piece of equipment cooling the hot synthesis gas exiting an ATR, a secondary reformer, or an SMR. The heat from the process gas is utilized to generate high pressure and high-quality steam for the process and to drive turbines. Depending on the downstream processes and the need for accurate temperature control, the WHB can be designed with one or two …

Waste heat boilers (WHB's) recover useful energy from exhaust gas streams from many industrial, waste and power generation processes and help to save fuel and reduce CO2 emissions. Our engineers have designed solutions for hundreds of applications from clean gas turbine exhausts through to the dirtiest and most arduous of conditions where fouling and corrosion are overiding design factors.
