Waste Heat Power Generation Environment / Energy

Waste Heat to Power (WHP) Generation

From small to big companies, most of the heat generated is not used and considered a waste.
By harnessing this “waste heat” using a WHP generator it is possible to produce electricity, allowing businesses to both save energy and help protect the environment.

Benefits

  • Reducing electricity consumption
    Waste heat can be turned into electric power.
  • Protecting the environment
    By reducing our electric consumption we also reduce the amount of fossil fuel needed to produce electricity thus lowering our carbon footprint.
  • Corporate Social Responsibility (CSR) and Sustainable Development Goals (SDGs)
    CSR and SDGs are gaining ever more recognition nowadays as we realize the importance of the environmental issues ahead of us. In this context a Waste Heat to Power generator can be a great asset to help a company attain its CSR goals.

We select the WHP system based on several parameters such as:

  • The temperature
  • The amount of heat produced
  • The type of Waste Heat
Electric power facilities Heat source Typical applications
Organic Rankine Cycle technology (ORC) Medium or low temperature Metal heat treatment, ceramic manufacture, glass production, incineration systems, cogeneration systems etc.
Stirling engine High temperature Garbage incineration plant, woody biomass boiler, industrial scale incineration systems, Industrial furnaces(for ceramic, firing, melting, combustion etc.)
Small steam-electric generator Steam Food industry, petrochemical industry, electronic component manufacturing etc.
Type of waste heat power generation

● ORC (Organic Rankine Cycle)

This system is a steam engine using organic matter instead of water, waste heat can be turned into electricity at medium or low temperature; 90-250 degrees.
ORC engine can also function using geothermal and exhaust gas heat.

● Stirling engine

Gas expand and contract depending on its temperature, by repeatedly warming and cooling a gas in an airtight chamber we can harness this movement to drive pistons and generate power.

● Small steam-electric generator

  • Electric generator using waste steam
    Small steam-electric generator can use steam coming from:
    Other machines
    The flash steam from recovery system
  • Steam Screw Expanders (SSE)
    The SSE is a generator adapted to small scale plants and specifically made to answer the common problems faced concerning small scale steam based power generation:
    Change in flow
    A small steam volume
    Low-pressure
    With a SSE it is possible to generate energy efficiently in small plants and at low cost.

Installation Support

We support you from the feasibility study to the installation and operation of your generator.

WHP project development planning

*Depending on each case we provide tailor made solutions to ensure your utmost satisfaction.

Feasibility study
The most important points for WHP are:
the quantity of gas
the way of recovering heat
Inquiry phase Research
  • Used fuels
  • the principal characteristics of the gas (temperature, pressure, amount of gas flowed, composition)
  • and the provenance of waste heat and how it is captured
  • the amount of available cooling water
  • The current state of the project
  • Installation place
  • Plumbing
  • Confirm blueprints
  • Measure the gas quality(as necessary(extra charge))
