IR radiation is generated using one of three different
technologies: electric, gas catalytic, or radiant gas (and radiant gas systems
are mainly used for space heating rather than process heating).

Electric
infrared technology offers more flexibility than gas-catalytic regarding the
fancied heating force. Electric and gas-catalytic IR advances have particular
qualities that make them pretty much proper relying upon the material and the
sort of process. Gas-catalytic IR frameworks by and large oblige a more
prominent capital venture than the other two, yet they have lower working
costs.
To choose which technology is ideal for a particular item or
process, various parameters must be viewed as, including item quality, working
costs, and generation rates. In processes that oblige fabric and paper drying,
gas-catalytic technology has a marginally predominant heating productivity as a
result of the force of the radiation it transmits and the measure of time the
item uses in the stove. As a rule, a gas-catalytic IR framework is a decent
decision for materials that oblige a considerable measure of vitality, for
example, a few materials, in light of the fact that its fuel costs are lower
than those of electric IR.
Electric IR is more suited to delicate materials that requires
a less-exceptional heat or to processes that need brisk reaction times or
shorter blasts of serious radiation from the heating gear
Gas-catalytic IR technology has an altered force thickness
that relies on upon the temperature of the fuel-oxygen response; it for the
most part does not surpass 2 kilowatts for every square foot (kw/ft2—that is 22
kilowatts for every square meter [kw/m2]). Interestingly, electric IR stoves
can rapidly and effectively differ the force of emitted heat while
accomplishing force densities of up to 37 kw/ft2 (400 kw/m2)—a trademark that
makes them predominant for quickly heating metals.
Both the Methods of IR heater firing holds its advantage and
limitation it totally depends on the process that is being needed for.
