Thermal Design of a Slag Tap Boiler Furnace

抄録

In the conventional design of slag-tap boiler furnaces, certain complicated procedures based on experience have been required because of their variety of construction. A new comprehensive design is explained here, being deduced from the thermal theory, so that a simplified design method may be introduced from the relation between the furnace heat-release and the form factor, and determined by the statistical data. Further, from the latest experimental information, a general viscosity equation of molten coal-ash slag is derived and the thickness of a fluid slag film is determined by the author. In particular, a simplified equation for calculation is deduced from the inherent operation conditions of the slag tap boilers.
