Industrial heating systems are made up of a circuit combining the technologies needed to provide heat efficiently to an industrial production process that is determined, guaranteeing the end product quality, maximising productivity and minimising energy costs.
Their efficiency is determined by their capability of complying with the quality requirements of the given products manufacturing process. The systems include all the technologies and elements required to melt or heat certain products. The energy efficiency of industrial heating systems is the key aspect because the said system should be able to manufacture products with the quality standards that are expected plus with lower energy consumption. Industrial heating systems that are efficient allow starting a production process with energy requirements that are reduced for each heated product unit at a certain temperature.
Generally, process heating technologies are designed around four types of principal energy:
Fuel-based Process Heating Systems
They produce heat energy through the combustion of gaseous fuels, liquid or solid, and then transfer it either indirectly or directly to the material. Combustion gases can be in contact with the material directly (direct heating through convection) or utilise a radiant heat transfer process by routing hot gases through panels or radiant burner tubes, hence separated from the materials (indirect heating).
Process Heating Systems Based on Electricity
They can transform materials through indirect and direct processes as well. For instance, electric current can be directly applied to suitable materials and leads to the direct resistance heating. High-frequency energy can also be inductively coupled to materials that are suitable leading to indirect heating. The electricity-based process systems (electrotechnologies) are normally used to perform operations like curing, drying, heating, forming and melting.
Steam-based Process Heating Systems
Steam-based process heating systems generate heating through indirect or direct heating application of steam. Same as fuel-based indirect and direct systems, steam is introduced to the process directly for heating (for instance steam sparge), or it is in contact with this process indirectly through a heat transfer system. Steam heating supply a large amount of the energy that is used in industrial process heating with lower temperature. Steam-based systems use is mainly for industries where the supply of heat is below or at around 400 degrees Fahrenheit and where there’s the availability of cheap fuel or even by-products to be used in the generation of steam. Use of co-generation (concurrent production of electrical power and steam) is another example where people use steam-based heating systems.
Hybrid Process Heating systems
Hybrid process heating systems utilise a mixture of process heating technologies that are based on different energy sources or different methods of heating of similar energy source to optimise their energy increase, increasing the overall process of thermal efficiency. For instance, a hybrid boiler system combining a boiler based on fuel with a boiler that is electrically based using off-peak electricity is sometimes used in lower-cost-electricity areas. ST Heating Services Ltd is located in Manchester as well as the North West and we are commercial heating engineers. We specialise in plumbing, LPG contractors, pump and boiler. Our contractors offer services of high quality, repairs and maintenance for heating and boiler units.
