Each of these four systems has different working conditions and efficiencies. From the perspective of customers, they all hope to choose a system with higher cost performance. For us, suitability is the most important thing. If we only look at the power generation efficiency of the system, the efficiency of the internal combustion engine and the external combustion engine is the highest, and its heat loss is low, and the combustible gas can be directly converted into electrical energy through mechanical energy.

Compared with steam turbine and ORC, steam medium is needed to convert mechanical energy and electrical energy, and the power generation efficiency is reduced. The advantage is that cogeneration can be applied in colder northern regions, and steam power generation can generate a large amount of waste heat, which is the first choice for CHP projects.

If customers want to increase additional income in addition to power generation, they can choose internal combustion engine and external combustion engine power generation system, because in addition to thermal power, they can get additional high value-added by-products such as wood acetic acid and wood tar, plus biomass charcoal, which can improve the project. The payback cycle is long, and the comprehensive utilization of biomass is eaten dry and squeezed out.
