Industrial Furnace : More Production and Less
Emission
Industrial furnace has wide applicability in both small and big
industries. It is an enclosed structure that produces heat for
industrial purposes. Made up of different kinds of heat resistant
(refractory) elements it can withstand long term use. The enclosed space
holds the materials, gas or air being heated until the desired
temperature is reached. Industrial furnaces are available in varying
temperature control options or set for a single temperature, depending
on the process for which the furnace will be used. Industrial furnace
commonly have one of the following atmospheres: air or oxidizing, inert,
reducing, salt bath and vacuum.
The important feature of the furnace include over temperature
protections, service or entry holes, view ports, computer interface and
application software are some of the features available on these
furnaces. Heat sources can be infrared or radiant, natural gas,
induction, conduction, electrical or dielectric.
The industry that widely use industrial furnace is steel industry. The
steel industry uses high-temperature, natural gas-fired furnaces, which
produce large amounts of nitrous oxide (NOx) per unit of
processed material. The latest furnace are highly efficient productive
and reduced NOx emission from all types of industrial furnaces. In this
type of furnace valve is used to oscillate the fuel flow rate to the
burner. Oscillation creates fuel-rich and fuel-lean zones within the
flame that retard the formation of NOx increasing heat
transfer to the load.
Lot of research is going on to develop advanced industrial furnace
designs that provide approximately 30% energy savings and hence CO[2]
reduction, 30% reduction in the furnace size, and 25% reduction of
pollutants including NO[x] as compared to current designs. The main
purpose is to establish such furnace that consume less energy and emit
low pollutant from a range of furnaces.
