LHV vs HHV Efficiency - Fulton

WebHeat of combustion depends on the relative lignin and holocellulose and extractive contents of wood. Cellulose and hemicellulose have a higher heating value of 18.6 kJ kg-1, whereas lignin has a higher heating value of 23.2–25.6 kJ kg-1. Higher heating values of extractives are about 32–37 kJ kg-1. WebIn one paper, I found the lower heating value (LHV) which can be expressed by LHV = 10.78H2(%) + 12.63CO(%) + 35.88CH4 (%) + 56.5C2H2 (%) + 64.5C2H6 (%) for … WebWhere local heat off-take is available, the economic case for biogas co‑generation is stronger than for an electricity-only plant. This is because co‑generation can provide a higher level of energy efficiency, with around 35% of the energy from biogas used to generate electricity and an additional 40-50% of the waste heat put to productive use. harem pants vs hammer pants
