If you are doing a project which requires
parts to function in extreme heating 1,200 °F, you need to have a heat resistant casting. It’s important to know, that all heat resistant products are
not the same. There are many factors that go into predicting which component is
good for your particular industry. Radiant tubes are one of the many different
types of heat resistant products available.
What are Radiant
The procedure of heating system do not
only depends on the furnace burner, but mainly on the radiant tubes. Tubes are categorised according to their construction. Heat is passed by radiation from the outer surface of the heated tube to the internal surfaces being heated. Different sizes and shapes
of various heat opposing substances are used for these tubes depending upon
their particular need, service temperature, and furnace atmosphere.
What is W-TYPE Radiant Tube?
A radiant tube heating consist of an
external radiant tube build-up of heat-resistant substance, burner assembly
comprising an inner tube situated within and spaced inwardly from said radiant
tube, said inner tube having a forward discharge end, means for transferring
combustion air into said internal tube for flow toward the forward end of said
inner tube, a gas supply pipe located within said inner tube and having a
forward end, means for delivering gaseous fuel to said gas supply pipe.
Radiant tube assembly
The current concept is a radiant tube assembly that
involves a burner assembly firing combustion gases into a combustion tube who
releases radiant heat energy from its external surface. A black ceramic coating
is applied to the external surface of the combustion tube to increase the
emissivity of the combustion tube and lower the temperature of the external
surface of the combustion tube. Semi-circular top and semi-circular bottom
inserts extending longitudinally along the length of a first section of the
combustion tube lower the combustion tube outer temperature.
