About Combined Heat and Power-CHP


The energy supply equipment not only provides electricity, but also heat too. This is named CHP. The heat provided can be used for hot water, heating facilities and steam. Additionally, it can also be used to generate cold. The combined utilization of heat and power can increase the comprehensive efficiency to more than 90% in the process of power generation. It can save as much as 40% of the primary energy and reduce carbon dioxide emissions by 60%. This is the reason why CHP is highly efficient and environmentally friendly.

High Safety


Products are fitted with many kinds of sensors and safety valves, integrating control, measurement and protection functions



► Cylinder temperature protection systemGas-train-of-400kW-MAN-biogas-generator-CHP-system-ETTES-POWER


Cylinder temperature sensors or exhaust manifold temperature sensors can measure the combustion or exhaust gas temperature and send signals to the control system to monitor engine's operation condition and ensure normal operation


► Detonation control system


Based on the signals from sensors, the controller sends out analog signals to ignition system after processing so as to adjust ignition timing, reduce load or shutdown to avoid detonation


► Gas leakage protection device


This avoids gas leakage and once the gas leaks, gas pipeline will 

be turned off and alarms will be sent out


► Lightning protection device


The device can introduce lightning into the earth and protect 

personnel and equipment from lightning stroke



► Smoke alarm systemSmoke alarm system ETTES POWER


Internal smoke status is detected in time and once excessive smoke is detected, the system would send out a warning to prevent fire spreading or explosion


► Electrical inlet and outlet shutter


The shutters control inlet and outlet automatically, i.e. close shutters when CHP unit stops or open them when CHP unit starts, 

thus these achieve automatic adjustment and prevent small 

animals entering into the unit when it stops. Once gas leakage 

happens, they are closed automatically to isolate internal air Remote-radiators-of-biogas-generating-set-CCHP-unit-ETTES-POWER

and prevent explosion

Application of Special Gas


● CHP solves the problem of waste disposal and protects

the environment. Electricity produced meets the local demand and public grid. Heat produced is recovered to optimize the living condition.


● With purification treatment, associated gas can be used as 

the fuel of CHP units to supply continuous power and heat for 

oil field drilling and guarantee the normal production.


● About 100-200m3 landfill gas with the heat value of 3.5-5.5kWh/m3 is produced per 1 ton landfill. It is a high-quality 

fuel used on the CHP units, and so this saves energy and protects the environment.
