There are a number of heat sources that Raser can use to develop green zero-emission heat recovery projects.  The following are the primary sources:

Waste Gas Heat Recovery (WGHR)

Some manufacturing processes often creates excess heat that is often discarded through smokestacks, forced through expensive pollution reduction systems, or simply radiated into the environment. WGHR is the process of converting this unused heat into useful power, often resulting in the production of clean electricity. Raser’s industrial waste heat recovery business can be applied to a number of industries that have exhaust waste heat, including cement, aluminum, steel manufacturing and oil. Raser executes through established strategic relationships with leading specialized engineering firms that serve these industries.

Liquid Heat Recovery (LHR)

Some manufacturers use water to cool their manufacturing process. This water needs to be cooled in order to circulate back through the plant. Raser’s power solutions act as a cooling process for this water while generating electricity.

Gas Compression and Let-Down Stations (GCLDS)

Gas Compression stations are prolific throughout the world.  Large gas turbines are used to pressurize gas pipelines.  The exhaust gases exiting from these turbines is very hot and is an excellent source of recoverable heat to generate power.  Let-down stations are used to let the pressure down off the pipeline to bring into businesses and homes.  The energy released from the pressure let-down can be used to generate power using Raser power solutions.

Bottom-Cycling (BC)

There are gas turbines, reciprocating engines, coal fired and nuclear power plants throughout the world that generate power.  The exhaust and hot water coming out of these primary power cycles are a tremendous source of  heat that can be recovered.  Raser power solutions are well suited to capture and utilize this heat to produce additional zero-emission power without any additional fuel.

Turbine Inlet Chilling (TIC)

Gas Turbines that are employed in warmer or tropical climates are not as efficient as gas turbines that are operating in cooler climates.  TIC is the process by which cool air is introduced into the turbine which provides as much as a 10% increase in efficiency.  This process can be combined on a skid-mounted Raser heat recovery system.

Solar Thermal (ST)

Raser has power solutions that use hot liquids to provide heat into the power cycle.  Geothermal plants use the hot brine from under the ground.  Solar Thermal projects can provide hot thermal oil to the Raser power systems to use as the heat source in the power cycle.  This type of heat recovery is very beneficial in providing power using the Raser modular power solutions where hotter ambient conditions exist without geothermal resources.
