Experimental firing of Miscanthus at Hjordkaer district heating plant; Forsoegsfyring med Miscantus hos Hjordkaer Fjernvarme

Technical Report:

Abstract

A series of measurements were taken during one day at a local district heating plant which was experimentaly fired with bales of Miscantus. A single measurement, lasting for half an hour, was taken of the emission. During measurement, the after-calculated yield was 69% of the nominal, which is 3.15 MW. The smoke outlet pipes had been previously cleaned and the filter bags inspected. Flue gas temperature was measured to be 91 degrees centigrade, flue gas volume (m{sup 3}(n,t)/h) was 3750, carbon dioxide content (volume %, dry basis) was 11.5, oxygen content (ditto) was 8.7, solid state concentration (mg/m{sup 3}(n,t) was 42, NO{sub x} concentration as NO{sub 2} (ditto) was 530 and CO concentration (ditto) was 138. (n,t indicates dry flue gas at normal condition, which is 0 degrees centigrade and pressure 1013 mb). The indirect efficiency according to DIN 1942 was 92.8%. Measurements were taken within a period of only half an hour and do not cover the situation where the bale is changed. (AB).
