The best investment among the technologies on the market today

The IBT Group has developed innovative applications that ensure maximum efficiency especially in those industries that need valuable heat carriers, such as saturated steam or superheated water, for their production process.


Combined production of electrical, thermal and cooling energy

The trigenerative system involves the combined use of Capstone and Century technologies for the combined production of electrical energy, hot water and chilled water through the insertion of a gas turbine and a specific heat recovery module (HRM) for the production of hot water from the exhaust gases of the turbine to feed an absorption refrigerator for the production of chilled water. The hot water produced by the recovery of thermal energy from the exhaust gases of the Capstone gas turbine can be used to feed an absorption refrigerator (chiller) that produces chilled water for use in the air conditioning system or in the process. Chillers use an absorption refrigeration cycle, based on state transformations, in which the refrigerant (water) in combination with the absorbing substance (lithium bromide) reaches the temperatures of a traditional refrigeration system with very low electricity consumption.

The CCHP system ensures a saving of > 30% compared to separate energy production, as well as a considerable benefit in environmental terms, which translates into a significant reduction in the emission of harmful gases such as CO2 into the atmosphere.


Saturated steam and electricity production

Using Capstone’s 65, 200, 600, 800 and 1000 kWe turbines, steam production can be maximised through the use of a special waste steam generator that uses the energy of the turbine’s exhaust gases as combustion air. The system involves the insertion of an oil-free gas turbine and a special recovery steam generator equipped with an air vein burner. The exhaust gases coming from the turbine, rich in oxygen and free of any trace of oil, are used as combustion air for the generator’s burner, resulting in considerable cost savings in steam generation.

The system allows primary energy savings of more than 30% compared to separate production of electricity and steam.


Combined heat and power generation

Capstone’s oil-free technology allows, in addition to the production of electricity, the extremely clean and oxygen-rich exhaust gases from the turbines to be used directly in the drying process, thus achieving the highest possible heat recovery. The turbine can be used for the joint production of electricity and hot air required by the drying process. This application is possible thanks to the air bearings, Capstone’s main patent, which do not require lubricating oil inside the turbines, ensuring the extreme cleanliness of the exhaust gases. The system consists of a Capstone methane gas turbine that produces electricity in cogeneration mode, entirely self-consumed for the production process, and exhaust gases that are directly conveyed to the drying process. The turbine is able to adapt the production of electrical and thermal energy to the load required by the plant thanks to the possibility of modulating the operation of the turbine itself.

The system ensures an overall efficiency of > 95%.


Combined generation of electricity and sub-zero brine

This is the perfect solution for the logistics and food industry that uses refrigeration at low temperatures. Thanks to the Capstone oil-free gas turbine, it is possible to produce sub-zero cooling energy at controlled temperatures with considerable energy savings compared to electric chillers. The Capstone gas turbine produces superheated water suitable for feeding a specific ammonia absorption unit for the production of glycol water from -6°C to -60°C. The methane-fuelled Capstone gas turbine produces electricity and, thanks to a heat recovery system (HRM), superheated water to feed an ammonia absorption refrigeration unit for the production of glycol water at controlled sub-zero temperatures.

The system ensures a saving of over 30% of primary energy with overall efficiency peaks of over 85%.


Combined production of electrical and thermal energy

The thermal efficiency of the internal superheated water distribution network can be increased through the use of Capstone technology, which allows the combined production of electricity and superheated water at the required temperature. All this is possible without limitations on the required in-out temperatures. The system involves the use of a Capstone gas turbine and a specific heat recovery module (HRM), suitably sized to produce superheated water at the required in-out temperature.

The system ensures a saving of more than 30% of primary energy, with a combined production of electricity and more than 80% of the heat recovered from the exhaust gases in the form of superheated water.


Maximising the efficiency of the existing steam generator

Capstone technology can be used to improve the efficiency of your existing steam generator by increasing its overall thermal efficiency. In fact, thanks to the post-combustion of exhaust gases, which are extremely clean and rich in oxygen, it is possible to increase the thermal efficiency of the existing steam generator by using all the thermal energy of the turbine as combustion air. The system involves replacing the existing generator burner with a special afterburner combined with a suitably selected power Capstone turbine to more efficiently produce electricity and saturated steam from the existing steam generator.

The system achieves overall efficiencies close to 100%.


Maximum sustainability for mobility with methane turbine

Capstone oil-free technology can be used as an additional gas (or alternatively LPG/Diesel) engine for environmentally friendly hybrid ZEV (Zero Emission Vehicles). Capstone microturbines combine the typical advantages of turbines (reduced levels of harmful emissions thanks to low combustion temperatures and extreme mechanical simplicity) with unique construction features such as the use of special air bearings that eliminate the need for lubrication.

The technology can be used to produce hybrid buses with several advantages:

  • the possibility of recharging the battery pack en route so there are no limits to the range
  • operation with different fuels (both diesel-LPG and methane)
  • extremely low levels of polluting emissions
  • extremely low maintenance
