WHAT IS INDUSTRIAL PROCESS HEATING?

Industrial process heating allows companies to use thermal energy to assist with
manufacturing processes or treatment of various materials and products. For
example, thermal energy may be introduced to help fabricate, modify, or enhance
the properties of steel, plastic, glass, cement, composites, textiles, and
chemical products used in industrial processes.

Nearly three-quarters of energy across the globe is used by industrial
applications. The majority of manufacturers use industrial process heating of
some kind in their operations, including indirect heating to hold stable
temperatures within a facility or direct heating for drying applications.


TYPES OF PROCESS HEATING SOLUTIONS

The right process heating solution for your business will be based on the
materials you want to heat and your heat source’s location. Several heating
solutions are available to fit your specific needs.

Thermal Fluid Systems
Process Bath Heaters
Biomass Energy Systems
Direct Fired Heaters
Waste Heat Recovery Systems
Circulation Heaters
Immersion Heaters

Thermal fluid process heating systems warm and recirculate thermal oil or other
thermal fluids to generate indirect heat. The system then supplies it to various
materials, machinery, or process systems. This indirect heat helps reduce the
chances that equipment will experience damage or workers will sustain burns.
Additionally, the controllability of thermal fluid systems makes precise
alterations to temperature possible.

Learn More About Thermal Fluid Systems

These safe systems use a simple bath solution to heat substances indirectly.
Many of these systems use water-glycol solutions for low-temperature process
heating as high as 250° F, while specialty operations requiring higher
temperatures can use salt melts to achieve this. Process bath heaters submerge a
heater within the bath solution, which sits at the base of the heater vessel.
The process coil in the tube-style burner warms up and subsequently heats the
process medium flowing through the system.

Learn More About Process Bath Heaters

Biomass Energy Systems assist in the combustion of waste materials in an
efficient manner, minimizing emissions and leveraging a range of fuels. Fuel
feed, furnace, and ash conveyor systems are included.

Learn More About Biomass Energy Systems

Direct fired heater designs are available in a wide variety of configurations
including API 560 compliant, non-API radiant convective, and convection only
style.

Learn More About Direct Fired Heaters

Waste Heat Recovery Units (WHRUs) recover the thermal energy from the hot
exhaust and gases discharged by industrial equipment such as incinerators and
turbines. This energy is then repurposed to heat other media and materials,
including asphalt and oil. WHRUs are available in various designs and styles. By
capturing heat that would otherwise go to waste, WHRUs allow facilities to use
that energy for other applications, making them a valuable addition to various
industries. They can greatly improve the overall efficiency of industrial
plants.

Learn More About Waste Heat Recovery Systems

Also called inline heaters, circulation heaters are applicable for systems
involving gasses, steam, oils, or other such fluids. They act as a custom
solution in corrosive or high-temperature system applications. These systems
lessen process heat loss by containing their heat-generating components within
insulated steel vessels. This construction also allows for superior efficiency
in the heaters’ rate of heat transfer.

Learn More About Circulation Heaters

The most prevalent of industrial process heating systems, immersion heaters are
highly efficient. These heaters can reach temperatures as high as 1,200° F and
have the ability to heat up tank contents of up to 500,000 gallons. Housings for
immersion heaters may consist of either carbon steel or stainless steel, to best
address your application’s requirements. They’re also available in models that
resist leaks and explosions to protect joints within terminal housing.

Learn More About Immersion Heaters


TYPES OF FUEL SOURCES FOR INDUSTRIAL HEATING SOLUTIONS

Industrial processing uses four main heat sources:

 * Fossil Fuels
   
   Industrial heating solutions that utilize fossil fuel-based sources produce
   heat energy through combustion. The ignition of solids, liquids, and gasses
   allows systems like ovens, furnaces, kilns, infrared heaters, smelters, and
   high-temp generators to produce indirect or direct heating using radiant heat
   transfer or convection, respectively. Fuel options include coal, oil, or gas
   that produces heat energy when burned. Indirect heating systems will use a
   combination of burner tubes and exhaust systems that ensure the fuel source
   doesn’t come into contact with process materials while allowing the heat to
   transfer through the tube to heat the material within it, similar to the
   workings of a water heater.

 * Biomass
   
   Industrial heating solutions may also use biomass, which is the most
   extensive type of non-fossil bioenergy source. Given their similarity to
   fossil fuels, which already have widespread uses for energy, biomass fuels
   are likewise suitable for the majority of industrial heating applications.
   Biomass produces bioenergy using many types of feedstock, including
   agricultural or wood waste material, as well as options for feedstock
   conversion pathways to generate process heat. Outside of direct combustion,
   there are also such pre-processing methods as liquefaction, torrefaction, and
   gasification.

 * Electricity
   
   Some industrial process heating solutions use electricity as fuel. Direct
   heating systems that use this fuel source tend to transfer electricity into
   workpieces and materials, while indirect systems use methods such as
   convection, conduction, and radiation. Induction heating systems, infrared
   ovens, and electric arc or vacuum furnaces typically use electric-based heat
   energy.

 * Hybrid
   
   Hybrid industrial heating systems may use a combination of fuel sources,
   technologies, and heating approaches to produce the ideal energy level and
   increase cost-effectiveness. For example, electric and fuel-based systems can
   help reduce energy expenses because of their controlled usage of electricity,
   with a system’s boiler running on electric energy only at non-peak times when
   it’s cheaper. Hybrid systems may also use a combination of convection and
   electromagnetic heat to optimize the direct heating processes that industries
   use for drying.

Environments ranging from manufacturing facilities to those involved in heavy
industry require reliable process heating systems to effectively maintain
stability in controlling both temperature and processes for fluids like gasses
and liquids. At Sigma Thermal Inc., our process heating systems can help your
application benefit from improved efficiency as well as facility, equipment, and
worker safety. Our high-quality process heating solutions use varying heat
sources, giving our extensive product line the ability to meet diverse process
heating needs.




PROCESS HEATING APPLICATIONS

No manufacturing element utilizes direct energy more than process heating, with
many industries and applications using these systems. Process heating is
applicable for:

 * Appliances
 * Electronics
 * Heavy Machinery
 * Paper Goods
 * Food Processing
 * Computer Chips
 * Farming Equipment
 * Textiles
 * Healthcare Products
 * Automotive
 * Shipbuilding
 * Drying Paints & Coatings
 * Cosmetics


MAINTENANCE SERVICES

Industrial process heating allows companies to use thermal energy to assist with
manufacturing processes or treatment of various materials and products. For
example, thermal energy may be introduced to help fabricate, modify, or enhance
the properties of steel, plastic, glass, cement, composites, textiles, and
chemical products used in industrial processes.

Over time, industrial process heating systems will experience wear as components
degrade via the buildup of debris or frequent contraction and expansion.
Typically, immersion heaters see an output decrease of about one-third over a
five-year period after initial installation. To help offset degradation, it’s
important to conduct regular inspections of heating system elements based on the
manufacturer’s instructions. It’s also best to have replacement heaters
available in anticipation of a future breakdown, which will help minimize the
potential for costly unscheduled downtime.
