The plasma system is designed as a single monoblock with equipment for operation of DC plasma torches, with arc starting devices (oscillators), superheaters, and industrial steam plasma torches connected to it.
The PLAZARIUM TPS/L universal plasma system is a combination of equipment integrated into a structural and functional package intended for conversion of electric energy into thermal energy with production of high-temperature ionized gas stream.
The plasma system is designed as a single monoblock with equipment for operation of DC plasma torches, with arc starting devices (oscillators), superheaters, and industrial steam plasma torches connected to it.The process steam plasma torches within the PLAZARIUM TPS/L universal plasma system are intended for creation of a high-temperature plasma jet of large volume and heat power. They are applied in any plasma-chemical reactors, furnaces and thermal plants for various high-temperature applications and other technological applications. The plasma system can be integrated into any thermal process as a high temperature heating source to replace fossil fuel based heating sources.
Process plasma torches with capacity of 15 to 65 kW are manufactured in series for this type of plasma systems (check Note 1 in Specification). The PLAZARIUM TPS/L universal plasma system is manufactured with a total power of 35 to 100 kW. An universal plasma system is supplied complete with 1 to 2 primary plasma torches and up to 2 backup plasma torches. Backup plasma torches allow the plasma system to have an industrially significant continuous cycle of operation, and also allow the replacement of consumables and maintenance of the plasma torches without the need to stop and shut down the thermal heating process. The bulk temperature of the heated stream (the plasma flame zone) is over 5000 °С. It can be controlled by changing the current and flow rate of the plasma-forming gas.
The composition of the water-steam plasma: The water-steam plasma consists mainly of hydrogen and oxygen, both of these components are active agents in oxidation-reduction reactions.
Gasification in steam atmosphere provides the way for complete conversion of carbon and hydrogen in the gasified substance into synthesis gas(СО + Н2), the presence of surplus hydrogen from the steam allows for regulating the ratio of carbon monoxide and hydrogen in the synthesis gas. The volume ratio of hydrogen in the synthesis gas obtained by plasma gasification amounts to 50 to 70%.
The quality of synthesis gas obtained by plasma gasification is as good as the quality of synthesis gas obtained by steam reforming of natural gas.
You can learn more about all the advantages of water-steam plasma and steam plasma torches in the corresponding article on our website.
The PLAZARIUM TPS/L universal plasma system is a complete set of all the necessary blocks and systems required for functioning and controlling of the primary and backup plasma torches.
ThePLAZARIUM TPS/L plasma system can be manufactured not only with steam plasma torches but also with air plasma torches and plasma torches for different gas mixtures, depending on the customer’s needs and tasks. The plasma-forming medium can consist of one-, two- or multicomponent gases (argon, helium, nitrogen, air, mixture of argon and nitrogen with hydrogen, oxygen, hydrogen, methane, syngas, ammonia, water, etc).
The plasma system has been designed with due regard to specific features of construction of the mobile plasma gasification units.
All main and auxiliary equipment is assembled in frames of special design in standard dimensions and has the possibility of subsequent installation in the container frame of 20, 30 or 40 feet (additional option).
All components of the product are equipped with control and measuring appliances and instruments, and distributed and unified information display systems. Numerical control of all plasma system devices and processes completely backed up with analog control allows using the plasma system with increased reliability. The product is delivered assembled; external utilities are to be mounted according to the design documentation. -

PLAZARIUM TPS/L plasma system:
Plasma torches within the TPS/L plasma system:
Notes:
1 - There is a scientific and R&D version of the PLAZARIUM TPS/L plasma system with a single plasma torch with a power of 15 and 25 kW (available for ordering only for universities and scientific organizations), as well as a version of the PLAZARIUM TPS/L universal plasma system with one basic plasma torch with a power of 35, 50, 65 or 80 kW and a possible additional plasma torch 15, 25 and 35 kW, as an additional option. All scientific and R&D plasma systems require an external cooling system and an external plasma forming gas generation and supply system (with the exception of the version for the use of steam as a plasma forming gas).
, 2 - The power supply sources and the other energy systems provide for automatic adaptation to any input voltage within the range of380-450 V for three phases according to the characteristics in the customer’s TOR.
3 - Universal plasma systems are designed to be integrated and mounted in a container of any plasma unit. The container of the plasma unit is capable of providing any required range of operating ambient temperature and climatic zone of operation according to the characteristics in the customer’s TOR.
4 - The dimensions of the monoblock of the basic version of the universal plasma system PLAZARIUM TPS/L are indicated. The monoblock of the scientific and R&D version of the PLAZARIUM TPS/L plasma system has overall dimensions of 850 x 1200 x 1800 (L×W×H, mm). Dimensions may vary and are determined within the framework of the Technical Project.
5 - It is possible to manufacture of the scientific and R&D version of the PLAZARIUM TPS/L plasma system with backup plasma torches as an additional option according to the customer's individual TOR.
6 - The life cycle of consumable elements depends on the manufacturing technology and type of the electrode, the type of arc stabilization, the type of plasma-forming medium, and characteristics of the power supply source.
7 - The plasma torches are developed for a particular plasma forming gas or gas mixtures (STEAM / AIR / NITROGEN / ARGON / HELIUM / OXYGEN / AMMONIA / CARBON DIOXIDE / HYDROGEN / METHANE / SYNTHESIS-GAS, etc.) according to the characteristics in the customer’s TOR.
8 - All the characteristics of the plasma torches and the plasma system are manufactured in accordance with the customer’s TOR.
9 - The structural design of the plasma torch and the entire plasma system is defined by the Contractor after agreeing the overall and connection dimensions with the Customer within the framework of the Technical Project. -
List of Equipment
PLAZARIUM TPS/L plasma system:
Notes:
1 - Closed-circuit cooling system requires an additional separate cooling unit.
2 - The control system is either independent for the entire plasma system, or fully integrated into the main console of the head unit.
3 - The total power of the additional separate cooling unit directly depends on the model of the plasma torch and the required parameters of the plasma system. -
Software
All components of the product are equipped with control and measuring appliances and instruments, and distributed and unified information display systems. Numerical control of all plasma system devices and processes completely backed up with analog control allows using the plasma system with increased reliability.
The plasma system has a main controller to carry out all operations correctly and manage various parameters, and a multilingual human-machine interface to set and manage all parameters.
The plasma system software allows manual or automatic control. The automatic control mode allows starting and stopping the plasma torches, as well as replacing the plasma gases without the participation of the operator. Manual control mode allows you to quickly adjust the plasma system for a specific technological aplication.
Controlled by touch panel and controller via LAN connection within the plasma system. The software monitors, controls and saves the statistics of the operation parameters of the plasma system components and all operator actions.
The universal plasma system has safety features, automatic blockers and disabling mechanisms. All electric cabinets and cable ducts are airtight, have sealing on their doors and airproof inlets and outlets which allows using an automatic fire-fighting system in each cabinet and the cable ducts after integration of the universal plasma system into the plasma unit container.
