Abstract

An apparatus for removing slag from the heat absorption surface in the furnace section and convection section of a heat exchanger including at least one blast nozzle disposed proximate to the surface and having at least two outlet orifices. A first fluid, such as water, is delivered to one of the orifices, and a second fluid, such as steam, is delivered to the other orifice to create a thermal shock and mechanical force which causes the slag deposits to separate from the heat absorption surface.
