Hydrogen Production By Steam Reforming - Chemical
Transfer-line steam generator. The outlet transfer line from the reformer is used to generate high-pressure (usually 650 psig) steam. The reformer effluent gas exits through the transfer line at about 1,400 o F and enters the tube side of a single-pass steam generator. BFW is fed through the shell side and becomes 650 psig steam.

This is the internal exchange of heat within the Brayton cycle. In a cycle operating with normal pressure ratio and turbine inlet temperature, the turbine outlet temperature is always higher than the compressor outlet temperature (Figures 7.12 and 7.13), i.e., T d is higher than T b and heat addition is from "b" to "c."The performance of this cycle may be improved by adding a surface

Heat Recovery Options - socalgas.com
2011-5-10 · If only high-pressure steam is desired, a heat recovery steam generator can produce up to 100 psi steam utilizing the exhaust gas of the engine-generator, but the amount of steam will be significantly less since much of the engine's heat is dissipated through the radiator. Natural gas turbines can produce large quantities of high-pressure steam.

4.3 Gas Turbines - UnderstandingCHP.com
Gas turbines produce a high quality (high temperature) thermal output suitable for most combined heat and power applications. High-pressure steam can be generated or the exhaust can be used directly for process drying and heating. Overall or total efficiency of a CHP system is a function of the amount of energy recovered from the turbine exhaust.

Turbo-expanders IPIECA
As the gas flows from the high pressure stream into the turbo-expander, the gas spins the turbine, which is coupled to a generator that produces electricity. Thus, by replacing a conventional control valve or regulator with a turbo-expander, the energy contained in the motive stream, that would otherwise be lost, can be converted to electricity.
