ABSTRACT:
Method and apparatus for heating ladles of the type commonly used in the foundry and steel industry is described whereby fluidized bed technology is employed to achieve greatly improved fuel efficiency. In the method, the particles forming the substance of the bed are drawn directly into the ladle from a mother fluidized bed unit wherein a flow balancing is effected to establish a relatively steady state, simultaneously as the flow to various ladles under treatment may be changed. The invention is particularly adapted to the use of coal as a fuel.
