Combined Heat & Power (CHP) also referred to as cogeneration is the simultaneous generation of electricity and heat energy from a single fuel source thus increasing the overall thermal efficiency of the plant.

Despite all the efforts being made in increasing the efficiency of thermal power plants (diesel&, gasoline engines, gas turbines, steam turbines); plants efficiencies are still in the region of 30% to 50% (in simple cycle state). This implies that about 50% to 80% of the fuel inputs are unused and given out to the atmosphere as waste heat. This waste heat contains significant amount of energy that if harnessed can increase the overall efficiency of the plant.

With the frequent power interruptions in Nigeria (some African countries inclusive), most businesses depends significantly on off grid power (i.e. self-generated power) with fuel cost taking a large chunk of their total operating cost. It therefore becomes important to optimize the efficiency of these power plants.

CHP systems offer a very effective solution in recovering most of this energy lost as waste heat from the exhaust of these power plants.

The key components of a CHP system are an internal combustion engine driving an electric generator and a heat exchanger. The internal combustion engine spins the electric generator to produce electricity; while the waste heat from the exhaust is captured by the heat exchanger which can be used for heating, cooling, dehumidification or other process applications

The following are the benefits of CHP systems:

• High overall Efficiency of Power plants (up to 90%)
• Reduction in CO2 emissions which is harmful to the environment
• Reduces demand on grid electricity
• Significant reduction in the utility cost of facility operation
• Reduction in the cost of fuel and overall cost of energy, improving the competitiveness of industry and business.

What We Offer

Installing a combined heat and power system requires expertise and capital. That is why at Entropy-Tech Energy Limited we carry out proper CHP installations by engaging our team of highly skilled engineers and project specialists. We also carry out project analysis to make sure that the capital to be invested in the CHP system is worthwhile using our techno-economic analysis model.   While we offer full CHP system installations, we also offer retrofit heat recovery system for already existing power plants. We also offer performance evaluation and maintenance services to ensure that the CHP system works optimally at all times. Depending on your power and heat requirements, our offered CHP systems are capable of delivering power, low temperature hot water (LTHW) and steam services to hospitals, hotel, factories, industries, special process plants.
