For industries that require combined heat and power (CHP) and perhaps additional cooling options, MBH offers power plants with Cogeneration and Tri-generation features.

• Cogeneration is the generation of both electrical power (standard power-plant output) and thermal energy (from exhaust heat), resulting in an overall energy generation efficiency of up to 90 percent.
• Trigeneration is the generation of a cooling current in addition to power and heat.

Cogeneration is a highly efficient means of simultaneously generating electrical power and heat from the same energy source. The process uses heat that is otherwise lost in conventional power generation to produce thermal energy (steam and / or water) needed for local industries or municipalities. This method proves more efficient than procuring power and heat separately.

While making use of the recovered heat, cogeneration ensures significantly increased efficiency of energy conversion and use - up to 90% efficiency - , decline in energy cost and lower emissions into the atmosphere. The use of cogeneration of power and heat is an efficient, economical and one of the most environmentally friendly practices. 

MBH has specialized in cogeneration since 1990. MBH power plants with cogeneration features yield a remarkably high electrical efficiency and permit economical operation even under partial-load conditions. Suitable heat exchangers are provided to decouple heat energy mainly from exhaust gas, cooling water, lube oil and supercharging air coolers so that heat energy is available for heating of water and steam generation. In addition, the low-temperature heat derived by means of heat exchangers can be used for lube oil and fuel in the secondary cooling circuit. Apart from the engine-generating set, essential elements of the CHP plant include: components for heat decoupling, exhaust line with sound absorber, exhaust gas cleaning systems (SCR catalyzer with oxidation stage), chimney, feed systems for fuel, lube oil, water and air, and the instrumentation system. To economically cover peak-hour heat requirements, exceeding the heat supply capacity of the engine system, the peak-hour boiler plant is normally added. Thus, MBH´s CHP plants are able to efficiently supply residential areas, commercial facilities or large-scale industrial undertakings with power and heat.

We can also offer the ORC (Organic Rankine Cycle) option, where the low temperature heat is converted into electricity, in order to further increase the plant´s efficiency.

Trigeneration technology allows the conversion of part of the heat produced into a cooling current that may be needed in addition to heat. Application examples would be the cooling of airport runways between landings, or air conditioning units.
