Waste Heat Recovery Unit (WHRU)
Small Scale Cogeneration Installations
The fire tube shell waste heat recovery boiler design is the economical solution for sub-critical waste heat boiler applications on gas engines, gas turbines and select heavy oil engines. The design provides a large disengagement area in the steam chest and is well suited for facilities with widely fluctuating steam loads. Available in single or multi-pass configurations; these units can be designed with a high level of flexibility to allow for multiple flue gas streams from up to four prime movers; though typically for gas turbines the realistic limit is two prime movers. In addition, supplementary duct firing and fresh air firing options are also available per customer specification and project requirements.
Combustion Processes
The cooling of exhaust gases downstream of thermal combustion processes (furnaces, fluidized beds, and rotary kilns) represents a special challenge. The high content of dust often present in the gases requires a special boiler design. Fire tube boilers are generally used in smaller applications where the thermal system heat release is below 20 MM Btu/hr and when high-pressure steam is not required. For larger applications, with high-pressure steam requirements, a water tube boiler is more suitable. There are many different process configurations available. Careful analysis of the end users emission requirements, steam requirements, process operating conditions, and operating cost objectives is our expertise.
Process Plants
Exhaust gases must be cooled by heat exchange in process engineering processes. Typical applications are plants for producing hydrogen using the direct reduction method or for producing sulfuric acid using the contact process. Waste heat boilers used for these purposes can be designed as water tube boilers and smoke tube boilers.
Heat Recovery Steam Generator (HRSG)
HRSGs are a strategic part of any CHP or Combined Cycle system; recovering the waste heat of exhaust gases from a prime mover (gas turbine, gas engine or heavy oil/diesel engine). McGuffy has a consolidated experience in CHP and Combined Cycle systems and a wide range of well proven solutions are available for any application focusing on all design and operation aspects based on to its capability to handle complex turn-key systems.
A reliable HRSG solution from McGuffy provides high thermal efficiencies, reduces thermal emissions and improves overall energy economics with high profitability of any industrial plant. Correct design is of course, a key point to make the above statement real in conjunction with the life cycle cost of the system. Depending on the range of prime mover outlet power; natural or forced circulation will be selected in order to achieve the required performances.
Adopting the correct plant design; our HRSG’s are suitable to recover waste heat from any prime mover’s flue gases whenever these are produced by combustion of natural gas or light oil.
Thanks to our group of skilled specialists, an integrated control system has been developed ensuring a complete control and supervision management of the HRSG, achieving an open architecture able to interface with a wide range of Distributed Control Systems.
