WHAT IS COGENERATION (CHP)?

Cogeneration, or Combined Heat and Power (CHP), is a highly efficient process that produces electricity and heat from a single energy source — such as natural gas, biogas, or biomass.

Instead of wasting excess heat as in conventional power plants, CHP systems recover and reuse it for heating, hot water, or industrial processes, achieving up to 90% total system efficiency.

Cogeneration units typically operate with gas engines, gas turbines, or steam turbines. The chemical energy in the fuel is converted into mechanical energy, which drives a generator to produce electricity. The waste heat released during this process is then captured and used productively — increasing overall efficiency and reducing environmental impact.

Benefits of CHP:

  • Energy Savings: Cogeneration systems can provide up to 30-40% more energy savings compared to traditional energy production methods. This is because they make use of waste heat, turning energy that would normally be released into the atmosphere into usable energy.
  • Cost Savings: Due to energy savings, you can significantly reduce your electricity and heating bills. Additionally, cogeneration systems require less maintenance and repair, which provides further savings in the long run.
  • Environmentally Friendly: Cogeneration systems help protect the environment by producing fewer greenhouse gas emissions. This way, you do not contribute to environmental problems like global warming and air pollution.
  • Reliability: Cogeneration systems can operate independently of the electricity grid, providing greater security against power outages.
  • Flexibility: Cogeneration systems can be customized to meet different needs. Therefore, they can be used for small and medium-sized enterprises as well as large industrial facilities.

WHAT IS TRIGENERATION (CCHP)?

Trigeneration can be defined as producing mechanical (electrical), heat and cooling energy simultaneously from one energy source. Absorption chiller that converts heat energy to cooling energy is invented by French scientist Ferdinand Carré in 1858 by using water + sulfuric acid. In 1926 Albert Einstein and his student Leó Szilárd developed it in alternative design, also known as, Einstein refrigerator and patented in 1930.

Absorption chillers consist of very few moving parts and need only heat energy. In absorption chillers, chilling principle is rely on vaporization-condensation cycle. There are four main heat transfer surfaces such as, evaporator, absorber, generator, and condenser. In a simple absorption chilling system, typically lithium bromide – water is used as a solution which is common in many commercial institutions.

MWM GAS ENGINES

MWM GAS ENGINES AND GENERATOR SETS – Reliability, Economy, Quality.

MWM’s product portfolio comprises gas engines and gensets in the output range from 400 kWel to 10,300 kWel. In this way, it is possible to set up power plants with an output of up to 100,000 kWel and more.

The gas engines can be operated with various types of gas, such as natural gas, shale gas, mine gas, biogas, landfill gas, sewage gas, and syngas. They are designed for maximum electrical and thermal efficiency, low operating and service costs, and high reliability and availability. Thus they achieve efficiency of over 90 percent.

MAN LIQUID FUEL ENGINES

Our reliable liquid fuel (HFO) machines – for cleaner power

MAN Energy Solutions has a long tradition of excellence in combustion engines – and produces the most efficient, advanced models on the market today.

Our successful diesel engines have been in use in power plants around the globe dating back to 1904. Known for their fuel flexibility and high efficiency, our latest models are ideal for base- and peak-load power generation. They are also very agile – offering fast start capabilities as well as high partial-load efficiency and low-load operation capabilities. MAN Energy Solutions also designs liquid fuel engines with two-stage turbocharging to boost fuel efficiency even further and avoid derating at high temperatures and altitudes.

Our liquid fuel engines are also very versatile: They run on crude oil, heavy fuels and distillate diesel oils, but also a range of renewable fuels – including vegetable oils, animal fats and biofuels. While our engines meet all emissions requirements alone or with additional technologies, we also offer exhaust gas after-treatment technologies to make them even cleaner and greener.

MAN DUAL FUEL ENGINES

Dual fuel engines: Deliver high performance, efficiency and versatility

Making the most of all fuel sources

MAN Energy Solutions designs dual fuel engines to achieve the same high performance and efficiency – whichever fuel may be available.

The main advantage of dual fuel technology is fuel flexibility. This makes it possible to take advantage of the low cost and superior environmental benefits offered by gas. If the supply of gas fuel is interrupted, the engine can continue operating using liquid fuel. In addition to natural gas, our dual fuel engines can also run on liquid biofuel or distillates like marine diesel oil (MDO), marine gas oil (MGO), crude oil and heavy fuel oil (HFO). Dual fuel engines from MAN Energy Solutions are known for their reliability, efficiency, performance and the ability to switch between fuel sources. And if you already have one of our liquid fuel engines, it’s easy to upgrade to dual fuel capability to meet changing needs.
