Abstract

Inventia se refera la un procedeu pentru optimizarea arderii carbunilor la generatoarele de aburi, destinat, în special, îmbunatatirii functionarii cu sarcina partiala, precum si scaderii continue a sarcinii minime, fara a fi necesar un foc de siguranta. Solutia tehnica a inventiei asigura o optimizare a arderii8 amestecului pe baza de praf de carbune, chiar în cazul unuo volume aproape constante de alimentare cu amestec a arzatoarelor, însa cu o scadere a alimentarii cu praf de carbune la un ventilator. Pentru o parte a arzatorului, concentratia amestecului de praf de carbune este mentinuta aproximativ constanta pe întregul interval de sarcina la o viteza de iesire din arzator aproape constanta. Aceasta se face printr-o dirijare a variatiilor concentratiei de praf de carbune, gaze de ardere, vapori de apa si aer, printr-o alta parte a arzatorului, pe baza inertiei prafului de carbune. Dirijarea are locdin fluxul de amestec pe directia lui de curgere, de preferinta în zona principala de ardere.
