The furnace head is the portion between a furnace end and a throat, and its type gives the name of a design. It highly affects on the combustion in concert with the constitutions of the burner jet and air-uptakes.
Model studies on the furnace head revealed followings:
(1) The furnace chamber preferably shall be divided into two spaces balanced each other in front and back by the center line of the furnace head.
(2) The standard dimensions of the single air-uptake furnace are given by following formulae.
For the spread uptake type For the central uptake type
Width: b=B'/2 Width: b2=0.88 B'
Length: l=B'/2 Length: l1=0.88 B'
Height:G=6B'/14.5 Height: G=6B'/14.5
(3) The approaching side walls scarcely play the role of an accelerator of combustion but are apt to increase the wear.
(4) The wear may be decreased without changing incoming air flow by declining the head roof or the end wall to the end.
