    2012-2-24 · Mechanical Stoker Firing. When fuel i.e. coal is put into the steam boiler furnace by means of a mechanical stoker, the firing of boiler method is referred as mechanical stoker firing. There are mainly two types of mechanical stoker firing systems. Under Feed Mechanical Stoker GmLoc DB Class 45 accucraft,From 1950 therefore several Deutsche Bundesbahn locomotives were equipped with an outer firebox with a combustion chamber and a mechanical underfeed stoker. The engines with operating numbers 45 010, 45 016, 45 019, 45 021 and 45 023 were provided with welded boilers and underfeed stoker equipment.
