Waste Heat to Power (WHP)
The energy and process-intensive industries generate a valuable byproduct that should recycle back to the user power generation.
The byproduct is waste heat, and there is an immense volume per facility that either overlooks or devalues this byproduct.
Waste Heat to Power (WHP) is the process that generates power from waste heat without adding any fuel.
The power recycled can be steam, preheated combustion air, electrical, district energy or a combination of all the resources.
The district energy can be hot water, heating, or cooling. Bottoming-cycle cogeneration process is another term for the WHP process.
​
We offer the full spectrum of cogeneration cycle processes. (Topping and Bottoming Cycles).​
The US Department of Energy (DOE) estimates WHP can generate over 1.5 GW of electricity in the U.S "Not counting the topping cycle opportunity."
​
According to"The Heat is Power Association (HiP)," which RAI is proud member states:
Waste Heat to Power (WHP) is the process of recovering waste heat and using it to generate power with no combustion and no emissions. WHP systems use the same technologies deployed in several industries.
Anywhere there is an industrial process that involves transforming raw materials into useful products, "steel mills, paper plants, refineries, chemical plants, oil and gas pipelines, and general manufacturing." heat is wasted as a byproduct.
This waste heat is produced whenever the operation is running, often 24 hours a day, seven days a week, 365 days a year.
If not recovered for reuse as lower temperature process heat or to produce emission-free power, the heat will dissipate into the atmosphere, a wasted opportunity.
​
RAI defines WHP as a Power Recycling to reflect our Same Fuel XTRAi Power® approach. We leverage our integrated technologies to satisfy the customer's unique applications. The following are some applications:
​
-
Blast Furnaces & Foundries: Iron, Steel, Aluminium Smelting
-
Refineries, Petrochemicals, Oil/Gas, Bioenergy
-
Mineral Rotary Kilns: Cement, Gypsum, Titanium/Magnesium Oxides, Borax
-
Bricks/Ceramic/Glass Tunnel Kilns
-
Incinerators/Thermal Oxidizers/Cooling Tower/Dryers
-
Natural Gas Pipeline Compressor Station
-
Engine (Reciprocating/Turbine)
​
WHP benefits:
Plant OpEx Reduction - CO2 Intensity Reduction - Plant Reliability Enhancement - Mitigates the Volatile Cost of Power
​
RAI Power Recycling package capacity range from 500 KW - 15 MW.
Topping Cycle Cogeneration
Initially, the process produces electricity from a single source of energy then recover the byproduct to district energy. The cycle simultaneously/sequentially uses power & heat from the same source.
RAI Topping Cycle Cogeneration capacity range: 200 KW - 10 MW.
