An Elliott STG is an efficient, cost-effective means of producing electric power from the excess thermal energy in
a steam system, from a conventionally-fueled source, or from an alternative fuel source such as biomass. Each
Elliott STG is configured to a customer’s specific requirements and takes the local utility cost model into account.
Depending upon applicable electricity rates, an Elliott STG can offer payback on the capital investment in three
years or less

 

Configuring an STG for cost-effective power generation
depends upon determining the right mix of elements,
including:
Š A defined steam supply
Š A clear understanding of how the electricity will be used
Š Whether the steam is also needed for other processes

The mix of these elements, and each installation, is always unique. Designing the best STG solution requires an
accurate understanding of the application and operating conditions from the start. A clear definition of the right
mix allows Elliott’s application and product engineers to match the STG to the customer’s specific requirements.
Elliott STGs operate in power applications such as combined heat and power (CHP), waste-to-energy, and
waste heat recovery. The alternating seasonal steam demand for heating and air conditioning at institutions such
as universities, medical centers, correctional institutions, and corporate campuses makes these facilities wellsuited
to an STG. However, the varying steam loads dictate a different system approach than do the relatively
unchanging process requirements of an industrial plant.
The prevalence of steam in industrial processes makes these plants excellent candidates for electrical cogeneration.
Steam availability often exceeds process requirements, and without an STG, the extra energy is
frequently vented and lost. An Elliott STG cost-effectively converts this excess thermal energy into electricity.
Industries that produce significant combustible waste, such as lumber, sugar, and food processing, can use this
material to fuel a boiler and produce low-cost steam. In these situations, an Elliott STG can pay for itself in a few
years.
