How efficient is a Stirling engine?

The thermal efficiency of Stirling engines is 40% while the efficiency of similar Otto and Diesel engines are 25 and 35%, respectively. The Stirling engine cycle is a closed regenerative thermodynamic cycle, with cyclic expansion and compression of the working fluid at various temperatures [7–11].

How does a Stirling engine work?

Every Stirling engine has a sealed cylinder with one part hot and the other cold. The working gas inside the engine (which is often air, helium, or hydrogen) is moved by a mechanism from the hot side to the cold side. When the gas is on the hot side it expands and pushes up on a piston.

What is micro CHP?

The term micro CHP refers to a group of technologies that generate both usable heat and electricity. The technology was developed to increase the amount of energy harnessed when burning fuel to generate electricity, thereby increasing the efficiency of the combustion process.

Where are micro CHP boilers made?

Each of the boiler companies has developed their own variant of micro CHP unit incorporating the MEC engine, now being manufactured in China. The UK variant is manufactured by Baxi, part of the BDR Thermea Group which also includes Remeha, De Dietrich and Br�tje.

What is micro combined heat and power (mCHP)?

Below, you will find a short outline of some of the sections to help you find the information you are looking for. Micro Combined Heat and Power is a term that refers to a group of technologies that generate both heat and electricity at the same time.

What are the different types of MicroCHP?

These range from fuel cell mCHP units which generate electricity and heat by extracting energy from fuel at a chemical level, to Stirling engine generators that use standard combustion methods to drive an engine. Learn all about the different types of microCHP engines in this section. How do micro CHP systems work in a home or business?
