CHPCHP (Combined Heat and Power)

CHP is commonly used in larger districtheating systems and industrial installationsHigh efficiency & low emissionsFuels: coal, biomass, waste or mixtures

CHP until nowCHP until now

Viable only in larger scale (> 3 MWe) andsubstituted by feed tariffs or green certificates

Expensive investments (long pay-back time) in

smaller scale

GasificationGasification

Gasification of biomass and especially woodGasification of biomass and especially woodthrough pyrolysis was common during the WW IIthrough pyrolysis was common during the WW II Carbon monoxide (CO) gasifiers for vehicles had aCarbon monoxide (CO) gasifiers for vehicles had avery low efficiency: about 20% of the gas was COvery low efficiency: about 20% of the gas was COand the rest normal flue gasesand the rest normal flue gases

Modern gasificationModern gasification

Modern gasification is a process of pyrolysis of thecombustible mass in 300500 C Modern gasification process gives a gas with 80% of the original energy value of the biomass From 1 m wood chips comes about 200 mproduct gas (1 bar)

Production gas

Clean gas, high hydrogen (H) and CO contents. Tar content in the gas is very low which prolong the

service interval of combustion engines
