Gas systems

A system is a collection of elements which are tailored to each other and interact in such a way that they can be regarded as a unit for specific tasks, senses or purposes and are separated from their environment in this respect.

Under this definition, a distinction is made between gas systems as to their purpose and function for gas distribution and gas utilization.

Knowledge of the type of gas system concerned is of major significance for operators of these systems, planning officers and system manufacturers since different statutory requirements apply to the different types and this results in the use of different safety standards and regulations.

Gas distribution systems include energy production and storage systems as well as distribution and transport systems. These include compressor systems, measuring systems and pressure control systems within the public gas distribution networks as well as the distribution networks within industrial sites.

Gas utilization systems are part of gas-using equipment such as gas appliances and industrial thermoprocessing equipment.
The aim of these systems is to control and regulate a heating process safely.

Gas appliances are systems used for cooking, heating, producing hot water and for cooling, lighting or washing purposes.

Industrial thermoprocessing equipment subjects substances or workpieces to the effects of heat energy.
The gas distribution system of industrial thermoprocessing equipment generally consists of a main gas train with a downstream single or multiple burner system comprising the burner(s), air supply and burner control unit.
