SAFETY PRECAUTIONS
Always follow the safety regulations applicable to the plant and observe the
following precautions:
° Wear protective clothing. Hot water causes burns and superheated
vapour is invisible.
° Before starting disassembly, make certain that t he desuperheater is
isolated from any source of pressure that may exist within the system.
° Carry out checking/maintenance of desuperheaters at least once two
years.
° The outer surfaces of desuperheaters reach tempe ratures approximately
equal to the temperature of the fluid flowing through them. For this reason,
if fitting a desuperheater in a potentially explosive atmosphere, check that
the explosion point of the atmosphere surrounding the desuperheater is
sufficiently higher than fluid temperature inside the desuperheater itself,
and prevent deposits of dust from forming on its outer surfaces.
° In the connection between the desuperheater and line, ensure the
equipotentiality of the system in order to prevent the accumulation of
electro-static charges on the outer surfaces of the plant, which could act as
an effective trigger in a potentially explosive atmosphere.
° Before carrying out any work on desuperheater co mponents, consult
CARRARO.
